A New Species

Five years observations in fields of young cane in Puerto Rico indicate a marked seasonal abundance during autumn and early winter, of all caterpillars except those of Diatraea saccharalis F., the species noted being Laphygma frugiperda S. & A., Mocis repanda P., Panoquina n. nero F., P. coscina Herrich-Schäffer, Perichares c. coridon F. and Marasmia trapezalis Guenée. The yellow aphid, Sipha flava Forbes, is most abundant during the winter and again in late spring, especially in eastern Puerto Rico. The eggs of Diaprepes abbreviatus L. are most abundant in June and September, and on the south coast were found only during these months. Thonalmus chevrolati Bourgeois, a red .and blue Lycid beetle accidentally established at Guanica by introduction from Santo Domingo, has spread north to Coloso and east to Ponce. The twice-stabbed lady-beetle, Chilocorus cacti L., introduced to prey upon the scales attacking bamboo, feeds on many other kinds of scales, and at times is found in cane fields. The injury produced by a new species of mite, Tetranychus sacchari McGregor, simulates mosaic disease.

The configuration of Canarian migration during the Conquest and colonization of the Spanish Caribbean was significantly influenced by its historic continuity, familial nature (with an elevated presence of women and children), dedication to agriculture, and contribution to the settlement of towns. This migration gave rise to quintessentially rural prototypes, such as the Cuban guajiro, linked to self-sustaining agriculture and tobacco; the Puerto Rican jíbaro, a coffee grower; and the Dominican montero or farmer from Cibao. All of these contributed a great many aspects of their speech, idiosyncrasies, and culture. The migratory dynamic has evolved since the Conquest and includes such processes as Cuban tobacco colonization, the foundation of townships in Santo Domingo and Puerto Rico (in order to further analyze their adaptation to the economic boom of sugar plantations in Cuba and Puerto Rico), and the uprising of slaves in French Santo Domingo, as well as the cession of the Spanish portion of the island to this country in 1795. This event merits special focus, due to its great transcendence in terms of the signs of identity that emerged during the rebellion of the Canarian vegueros against the monopoly within the Havana context, and the defense of their configuration as a distinct people in San Carlos de Tenerife: processes that explain their response to 19th-century innovations in Cuba and Puerto Rico and to Dominican political avatars, as well as their attitudes toward criollismo and emancipation. Their singularities are reflected in the mass Cuban emigration that took place during the early decades of the 20th century.

The genus Abbrosoga Caldwell (Delphacidae: Delphacinae: Delphacini) was described in Caldwell & Martorell (1951) to include the single species Abbrosoga errata Caldwell, 1951. Here, a second species, Abbrosoga multispinosa n. sp. is described. Revised diagnostics are presented for the genus and A. errata, including a key to species. A compiled list of 64 delphacid species from Puerto Rico is presented, with updated nomenclature, including the new species and a new record of Delphacodes aterrima for Puerto Rico.

Sipha Flava

Survey work in 1935-36 on sugarcane insects of Puerto Rico, especially those which may transmit mosaic disease, is described. Previous work is cited; climate, geography, and methods are outlined briefly. Aphis maidis was found to be rather abundant on tasseled corn, sparingly present on several grasses, and scarce on cane. Hysteroneura setariae was moderately abundant on some grasses, occasional on cane along the south coast, and rare on cane elsewhere. Sipha flava was widespread on cane, sometimes injurious, and small numbers occurred on grasses. Carolinaia cyperi was found in moderate numbers on a sedge. A. maidis was most numerous in the rainy season, the other three in the dry season. Mealybugs were numerous, especially on mature cane. Saccharosydne saccharivora was widespread but seldom numerous on cane. Some minor insect notes are recorded. Aphis maidis seems likely to be important in mosaic dissemination, because more abundant in areas of rapid than of slow spread. Hysteronera and Carolinaia seem less likely to be important, and the other insects named seem unlikely to be implicated at all. Some aphids not breeding on grasses may be important.

Neoaplectana Carpocapsae Weiser

A survey was conducted to determine the presence of entomogenous nematodes which might parasitize Diaprepes abbreviatus (L.) larvae in Puerto Rican soils. One larva (2.3%) was parasitized with Heterorhabditis sp. Poinar when 4-month-old larvae were placed in the soil at eight different sites throughout the Island. Soil samples, taken from sugarcane fields and pasture lands in five geographical regions during July and September 1980, and January and April 1981, and inoculated with D. abbreviatus larvae did not reveal entomogenous nematodes. In the laboratory, when Neoaplectana carpocapsae Weiser was introduced into sterile soil from these regions, 40% of the exposed D. abbreviatus larvae became infected. We believe this is the first report of the entomogenous nematode, Heterorhabditis sp., occurring in Puerto Rico.

A New Species

A new species of eurysquilloid stomatopod,Eurysquilla petronioisp. nov., is described from the tropical western Atlantic.Eurysquilla petronioisp. nov. is the fourteenth species of the genus to be recognized worldwide, the fifth species from the western Atlantic and the second from Brazilian waters. It is most closely related toE. maiaguesensisfrom Puerto Rico, but differs chiefly in having an unarmed versus apically spinous rostral plate and 6 or 7 rather than 8–10 teeth on dactylus of raptorial claw. A key to the species of the genus is provided.

Compensation Hypothesis

ABSTRACTThe Functional Compensation Hypothesis (Hochberg 1986a, b) interprets frequent expression of pronominal subjects as compensation for frequent deletion of agreement marking on finite verbs in Puerto Rican Spanish (PRS). Specifically, this applies to 2sg.túwhere variably deleted word-final -smarks agreement. If the hypothesis is correct, finite verbs with agreement deleted in speech should co-occur more frequently with pronominal subjects than finite verbs with agreement intact. Likewise, social dialects which frequently delete agreement should show higher rates of pronominal expression than social dialects which less frequently delete agreement. These auxiliary hypotheses are tested across a socially stratified sample of 62 speakers from San Juan. Functional compensation does show stylistic and social patterning in the category of Specifictú, not in that of Non-specifictú. However, Non-specifictúis the key to frequency differences between -s-deleting PRS and -s-conserving Madrid; hence the Functional Compensation Hypothesis should be discarded. (Functionalism, compensation, null subject, analogy, Spanish, Puerto Rico)
