NO. 2041. THE INSECT FAMILY DELPHACIDAE— CRAWFORD. 565 



Male pygofers large, aperture rather circular; anal tube enlarged 

 apically; genital styles contiguous, or nearly so, on enlarged basal 

 portion, apically slender, arcuate, acuminate, almost touching at tip. 



Redescribed from numerous males and females from the following 

 localities: Jamaica (Van Duzee), Mexico (Baker), Jalapa, Vera Cruz, 

 Chiapas, Guadalajara, Mexico (Crawford), Belize, British Honduras 

 (J. D. Johnson), Nicaragua (Baker), and St. Louis, Mo., (Baker). 

 The specimens from Nicaragua had been determined by Melichar as 

 C. swartzii. The specimens from Mexico are uniformly much darker 

 than the rest, both on body surface and elytra. Throughout the 

 series there is a gradual variation in the coloration of the frons from 

 brownish with black dots and spots to entirely black with perhaps 

 a few lighter spots very small in extent. The body surface, also, is 

 widely but gradually variable, so that neither of these characters can 

 be used to separate species, as was done by Stal in describing his 

 species swartzii. This species, both according to authentically deter- 

 mined specimens and the original description, is not distinct in any 

 way, and therefore becomes a synonym. The species is apparently 

 limited to the Tropics and the southern portion of this country. In 

 all the series there are no brachypterous specimens. 



COPICERUS IRRORATUS THORACICUS Guerin. 



Copicerus thoracicus Guerin in literature. 

 Seven specimens from Havana and Cayamas, Cuba (Baker), have 

 been determined as C. thoracicus Guerin, but are not specifically dis- 

 tinct from the above species. The following differences are constant 

 enough to warrant its separation as a varietal form, however. Body 

 uniformly smaller, more slender; median frontal carina rather con- 

 spicuously raised, much more so than in species. 



COPICERUS INSIGNICORNIS Lethierry. 



Asiraca insignicomis Lethierry '90: 150. 



This species was described as belonging to the genus Asiraca, but 

 by the description it is easy to recognize it as a Oopicerus. Perhaps 

 it is the same species as the tropical irroratus, but until further evi- 

 dence is obtainable it will remain as a distinct species. 



LocaUty: Venezuela, South America. 



Genus PENTAGRAMMA Van Duzee. 



Body robust, very large. Head large, broad, about as broad as 

 pro thorax; vertex longer than broad, produced a little before eyes, 

 sides rather straight, subparallel, rounded in front; frons broadly 

 ovate, broadest at ocelU, with two median carinas over entire length 

 passing separately onto vertex, diverging and following the curve of 

 frontal sides; carinae not sharp; apex of head tumid; face convex; 

 clypeus long, large, convex; gense large. Eyes large, not deeply
