Three new monotypic genera in the family Zerconidae (Acari: Gamasida) from the United States are described: Krantzas gen.nov. (type species K. mirificus sp.nov.), Lindquistas gen.nov. (type species. L. amyihetes sp.nov.), and Hypozercon gen.nov. (type species. H. macleani sp.nov.). Krantzas is related to genera characterized by absence both of adgenital shields and a single opening of glands gv2, and is also related to genera characterized by peritremal shields terminating truncately behind the fourth pair of coxae. In this genus the additional lateroventral shield is situated between the peritremal and ventroanal shields. Lindquistas is related to genera characterized by the peritremal shield terminating truncately behind the fourth pair of coxae and by having two short, smooth peritremal setae. Members of this genus are similar to those of Macrozercon Błaszak and Bledas Halašková. Hypozercon is related to genera characterized by having the peritremal shields extended posteriorly and having two unequal setae on the peritremal shield. Members of this genus are similar to those of Mesozercon Błaszak and Neozercon Petrova.

Resumen: Antecedentes y Objetivos: La avena de mar, Uniola paniculata, se distribuye en el Caribe, los Estados Unidos de América y México. El objetivo de este trabajo es reportar su presencia y registro en el estado de Campeche, México. Métodos: Se colectaron ejemplares de la familia Poaceae creciendo en una duna frontal al suroeste del estado de Campeche, específicamente en la Isla del Carmen. Las colectas fueron procesadas y herborizadas, para su conservación e identificación.Resultado clave: Con la identificación de ejemplares, y después de hacer una revisión de su distribución, se registra por primera vez la presencia de Uniola paniculata (Poaceae) en la Península de Yucatán, representando una contribución al conocimiento florístico de la región y a la flora de México.Conclusiones: Esta especie solo había sido reportada para la costa del Golfo de México, en los estados de Tamaulipas, Veracruz y Tabasco. Este registro adquiere relevancia por el papel ecológico de este pasto en las dunas costeras.Palabras clave: avena de mar, conocimiento florístico, dunas costeras, flora de Campeche.Abstract: Background and Aims: The oat sea grass, Uniola paniculata, is distributed in the Caribbean, the United States of America and Mexico. The aim of this work is to report its occurrence and record in the state of Campeche, Mexico.Methods: Individuals of the family Poaceae were collected growing in a coastal dune in the southwest of the state of Campeche, particularly on the Isla del Carmen. The collections were processed and herborized for their conservation and classification.Key results: With the individuals’ identification and after reviewing its distribution, this is the first report of the presence of Uniola paniculata (Poaceae) on the Yucatan Peninsula, representing a contribution to the floristic knowledge of the region and the flora of Mexico.Conclusions: This species had only been reported from the coast of the Gulf of Mexico in the states of Tamaulipas, Veracruz and Tabasco. This record is relevant because of the ecological role of this oat sea grass in the coastal dunes.Key words: Campeche flora, coast dunes, floristic knowledge, sea oat.

Тhe agromyzid (Diptera: Schizophora: Agromyzidae) fauna of America north of Mexico is described in the first part of this publication, including a genus key and discussions on morphology, life history and classification. The second part is a species-level revision of the family in the “Delmarva” states of the United States of America, that is, of the District of Columbia and the surrounding states of Delaware, Maryland, Virginia and West Virginia. The fauna of this region includes 156 species. This study presents 346 new state and provincial records and 23 new country records, two of which are new continental records (Agromyza abiens Zetterstedt and A. apfelbecki Strobl). Liriomyza endiviae Hering is no longer considered to occur in North America. Fifteen species are newly described: Agromyza echinalissp. nov., Melanagromyza brunkeisp. nov., M. eoflacensissp. nov., M. glyptossp. nov., M. rutellasp. nov., Ophiomyia capitoliasp. nov., O. cupreasp. nov., O. galiodessp. nov., O. heleiossp. nov., O. kaliasp. nov., O. laticolissp. nov., Cerodontha (Poemyza) ungulasp. nov., Phytomyza avicursasp. nov., P. catenulasp. nov., and P. winklerisp. nov. Four new species-level synonyms and one genus-level synonym are provided: Agromyza marmorensis Spencer syn. nov. is included as a synonym of A. aristata Malloch; Melanagromyza fastosa Spencer, syn. nov. is included as a junior synonym of Ophiomyia tiliae (Couden); Melanagromyza verbesinae Spencer is considered a synonym of M. vernoniana Steyskal; Phytomyza ranunculoides Spencer, syn. nov. is included as a junior synonym of Phytomyza loewii Hendel; the genus Liomycina Enderlein, syn. nov. is included as a junior synonym of Phytobia Lioy. Ophiomyia ultima (Spencer), comb. nov. is recombined from Melanagromyza. Euhexomyza albicula Spencer, stat. reinst., comb. nov. is resurrected from synonymy with E. winnemanae (Malloch). New host records are given.

Agathilla Westwood is an endemic genus of the family Ichneumonidae in North America, with three species from the United States of America and two from Mexico (A. fulvopicta Westwood in Belén Barranca ―no state name in label― and Durango; A. bohartorum Wahl in Durango, Estado de México, Jalisco and Zacatecas). This is the first record of A. bohartorum collected on Bidens pilosa Linnaeus (Asteraceae).

AbstractTwo new families and three new genera and species of Crinoidea from the Icla and Belén formations, Bolivian Devonian, are described. The material is identified as Meperocrinus angelina n. gen. n. sp., from the Icla Formation of the Sub-Andina region, Tuberocrinus lapazensis n. gen. n. sp. and Aenigmaticumcrinus rochacamposi n. gen. n. sp., both from the Belén Formation of the Bolivian Altiplano. Meperocrinus angelina n. gen. n. sp. is an Emperocrinidae, a family described from the Silurian of the United States of America. Tuberocrinus lapazensis n. gen. n. sp. is assigned to a new family of Dimerocrinitacea, the Tuberocrinidae n. fam., which is closely related to Pterinocrinidae that already has representatives in Bolivia (Apurocrinus sucrei McIntosh), Argentina (Pterinocrinus? australis Haude), and Colombia (Bogotacrinus scheibei McIntosh). Aenigmaticumcrinus rochacamposi n. gen. n. sp. is also as assigned to a new family of Dimerocrinitacea, the Aenigmaticumcrinidae n. fam.; a family with very distinctive features. These data demonstrate that the Malvinokaffric crinoid fauna in Bolivia has a mixed origin, with forms that arrived in South America from Europe (Old World Realm) and United States of America (Eastern America Realm) during the late Silurian or earliest Devonian, as well as a local stock, which evolved to highly endemic lineages.UUID: http://zoobank.org/f03120c6-264a-4ae9-81e0-46bfe844e65e.

The present is a particularly appropriate time to embark on a comparison of the demographic situation in the United States of America and that in England and Wales. P. K. Whelpton's study,Cohort Fertility: Native White Women in the United States, and the Report on the Family Census of 1946 conducted under the auspices of the Royal Commission on Population, have recently been published. These two works, one American and the other British, deserve careful study. This paper is designed mainly to make a broad comparison of the populations of the two countries and to provide a background for readers of Whelpton's book and of the Family Census Report.The author wishes to acknowledge the ready assistance he received, on all occasions, from officials of the U.S. National Office of Vital Statistics and of the U.S. Bureau of the Census.
