In my revision of the North American Eucosminae (Bull. 123. U. S. Nat. Museum, p. 172, 1923) I applied the generic name Exentera Grote to a small group of closely related species including improbana Walker (=cressoniana Clemens) and spoliana Clemens. I did this upon the assumption that, in the main, Fernald and others had correctly identified the Grote species. Although I had gone over the Fernald collection at Amherst, Mass., I did not see the Grote types, and assumed they were in the British Museum and so stated in the revision (p. 174).

Natural Groups

AbstractThe genus Ips is one of four closely related genera in the tribe Ipini, sub-tribe Ipina (De Geer 1775, Balachowsky 1949, Nunberg 1954, Hopping 1963). There are now 32 species of Ips recognized in North America, with a few more as yet undescribed. This paper defines the groups of closely related species with observations on the group relationships of species from other parts of the world. Work is in progress to define the North American species in each group.

A comparative study was made of the sequence of the GBSS1 gene fragment in accessions of closely related species Elymus margaritae, E. komarovii, and E. transbaicalensis from Siberia. Nucleotide sequences of the gene were determined for St subgenomes in accessions of E. margaritae and E. komarovii from classical habitats. The StH-genomic constitution was confirmed, and microevolutionary relationships between species were evaluated by constructing the NJ dendrogram. It was shown that variants of the St subgenomes in accessions E. margaritae GUK-1009 and E. komarovii AUK-9803 belong to the North American ancestral line St2 of the genus Pseudoroegneria, in contrast to accessions E. margaritae AUK-0650 and E. komarovii GAR-0501. The latter belong to the Asian branch of St1, together with variants of subgenomes in the species E. gmelinii and E. pendulinus. That is, according to the differentiation levels of the St subgenome, accession E. margaritae GUK-1009 (holotype) is significantly distanted from the accession AUK-0650 (paratype), which in turn is close to accessions of E. komarovii and E. transbaicalensis from East Sayan. According to levels of differentiation of the H subgenome, the studied species did not show noticeable differences.

Tentative Identification

The genus Pseudophysaloptera, recognized as a genus distinct from Physatoptera, is tentatively considered monotypic. The several species previously assigned to the genus Pseudophysaloptera, and the closely related species Physaloptera kotlani, have been reduced to one polytypic species, Pseudophysaloptera formosana, with two subspecies, P. f. formosana and P. f. soricina. The former occurs in Oriental species of Suncus, while the latter occurs in Palaearctic and Ethiopian soricid insectivores. North American specimens, which may represent a distinct species, are tentatively assigned to P. f. soricina. Presently available collections are only sufficient for a tentative identification of the Nearctic form.

In his paper on the genus Scolops (Kansas University Science Bulletin, Volume XVIII, page 417, 1928), Breakey comes to the conclusion that Scolops cockerelli Fowler is a synonym of Ball's Scolops robustus. On pages 427-428 he records the comparison of specimens of a number of closely related species with the type specimen of Fowler's species by Mr. W. E. China of the British Museum.

The north-western European species of the laevigatus-group of Apanteles are revised. Forty species are dealt with, of which twenty are described as new. Brief notes are added on North American species of the group in the British Museum (Nat. Hist.) to assist their eventual correlation with the European species.

Abstract In August 2018, the North American Coalition for Insect Agriculture (NACIA) organized a 3-d conference, Eating Insects Athens, in Athens, GA. The conference built on the success of the 2016 event, Eating Insects Detroit, and highlighted progress in both research and industry linked to insect agriculture. NACIA was created as a platform to strengthen an industry currently in its infancy. Goals of NACIA include, but are not limited to, promoting discussion about insect agriculture, educating, and streamlining efforts aimed at developing quality products for consumption by humans, livestock, poultry, or aquaculture. The 3-d Eating Insects Athens conference consisted of presentations, outreach events, and small group sessions to further develop the mission of NACIA. This overview article highlights some of the topics discussed at the conference, including optimizing production systems, developing standard operating procedures related to quality assurance, and investigating key issues such as palatability and bioavailability of insect nutrients, allergenicity, animal welfare, and ethics. Such research has the potential to improve the environmental impacts, resource efficiency, public acceptance, and regulatory approval of insect agriculture. Though the field and study of insect agriculture is young, the increased interest in research indicates a promising future.

Work undertaken in connection with Mr. C. P. Kimball's projected list of Florida Lepidopera has revealed a number of problems in the North American species usually referred to Diasemia Hübner ([1824-25] p. 348), type Pyralis literalis Denis and Schiffermüller (=Phalaena litterata Scopoli) (Figs. 1, 2). A structural study shows that these species belong to five groups, generically distinct from one another and from the type species of Diasemia. Diasemia alaskalis Gibson (Fig. 3) is congeneric with Udea ferrugalis (Hübner) and should be known as Udea alaskalis (Gibson), new combination. I have characterized the genus Udea Guenée in an earlier paper (Munroe, 1950). Diasemia plumbosignalis Fernald (Fig. 10) and related species belong to the genus Choristostigma Warren, 1892: 440. The species of Choristostigma will be discussed in a separate publication. Diasemia magdalena Fernald and an undescribed species belong to the genus Daulia Walker (1859: 975) hitherto known from the tropics of the Old World and from Argentina. Hydrocampa ramburialis Duponchel and Desmia? janassialis Walker require new genera.

The Family

Four species of the water snake genus Natrix have a distinctly different pattern of chromosomal morphology than found in two species of the related genus Regina. Natrix all have a karyotype with seven pairs of large or medium-sized submetacentric autosomes, three pairs of medium-sized subtelocentric autosomes, and seven pairs of small metacentric autosomes. All have a 2n of 36 with a submetacentric Z and submetacentric or subtelocentric W. The autosomal complement of Regina consists of seven pairs of large to medium-sized submetacentrics, five pairs of medium-sized submetacentrics, and five pairs of small metacentrics. The Z and W are both submetacentric chromosomes. The sex chromosomes are easily distinguished in both genera. The relationships of Natrix and Regina and Old World Natrix are discussed, as well as chromosomal variation in closely related species in the family Colubridae.
