Chromosomes of 24 curculionoid species from the Greater Puerto Rico Region, including the U.S. Virgin Islands are listed. Seven are endemic and eight are notable agricultural pests. The male meioformula of the broadnosed weevils (Brachyderinae, Otiorhynchinae) as well as of the brentid Cylas formicarius elengantulus is the expected 10 + Xyp, except for the phyllobiine Lachnopus kofresi from Mona Island (16 + Xyp). Representatives of the other curculionid subfamilies had higher autosomal numbers and primitive sex bivalent, Xyp. An exception was Anthonomus eugenii, which has a sex trivalent (X1X2Y) in the male. For morphological and cytological reasons, Lachnopus coffeae montanus Marshall, L. seini Wolcott, and L. yaucona Wolcott were synonymized with L. coffeae Marshall (NEW SYNONYMIES). One species of Ischionoplus (Brachyderinae) is new to science and it is endemic for Mona Island.

Scientific Survey

The necessity for a systematic review of the Homoptera of Puerto Rico is apparent when an attempt is made to identify specimens by means of the only available publication, the section of the "Scientific Survey of Puerto Rico and the Virgin Islands", relating to the Homoptera (Osborn 1935). This section lists 152 forms of which eight are definitely referred to the Virgin Islands. Scattered subsequent publications and additional plant quarantine records which are listed in "Insecta Borinquenses" and "Supplement" (Wolcott 1936 & 41) have added about 26 more forms for Puerto Rico. A recent faunistic treatment lists 28 species for Saint Croix, V. I. (Beatty 1944), and a similar treatise (Ramos 1947), includes 23 forms from Mona Island. While Mona Island is a political subdivision of Puerto Rico its fauna shows closer affinity to that of Hispaniola, therefore Mona Island will not be included in this review. On the other hand Saint Thomas, V. I., though politically separated, is ecologically related and forty records for this island are included herein even though these records were secured in four hours collecting and certainly are very incomplete.

This article adds to the growing literature about how the Supreme Court's decisions in the Insular Cases affected the residents of the U.S. territories. It focuses on the territory of Guam, which lacked juries in both criminal and civil trials until 1956–nearly sixty years after the island became a U.S. possession. Residents of Puerto Rico, Hawaii, and the Virgin Islands had limited jury trials, but Guam was left out due to its strategic military significance as well as racialized ideas about the capabilities of Chamorros, the native inhabitants of the island. This article recovers the struggle by Guamanians to gain jury trials. It argues that independence movements, like those in the Philippines and Puerto Rico, were not the only forms of resistance to American empire. Through petitions, court challenges, and other forms of activism, Guamanians pushed for jury trials as a way to assert local agency and engage in participatory democracy. For them, the Insular Cases were not just abstract rulings about whether the Constitution followed the flag; they deeply affected the administration of justice on the ground for ordinary Guamanians.
