Notes on the Genus Dysdercus 
117 
gins, which are luteous, deeply infuscate, with a small spot 
towards the inner angle of the corium, accompanied by a 
streak following the course of the radial vein, black; the 
membrane black, the apex narrowly albido-limbate. 
The anterior collar and posterior disc of the pronotum, 
the epimera and acetabula, sparsely punctate; the clavus 
and the corium thickly punctate; the rest of the body im- 
punctate. 
The rostrum reaching to the posterior margin of the 
second visible abdominal sternite. 
The male parameres with two spurs projecting down- 
ward toward the ventral surface, both short, of approxi- 
mately equal length, obtuse, cylindrical, the distal one per- 
pendicular to, the proximal one forming an acute angle 
with the axis of the paramere, the shaft of the paramere 
with a strongly dorsally reflected flange arising from the 
outer ventral surface, the distance between the tips of the 
spurs roughly equal to that between the tip of the proximal 
spur and the apex of the lateral flange. 
Length, from the apex of the clypeus to the tip of the 
membrane of the hemelytra: $ $ 9.5-12.5 mm. $ $ 7.5- 
11.5 mm. 
Maximum breadth of the pronotum : $ $ 2.5-3. 1 mm. $ $ 
2. 0-3.0 mm. 
Based on measurements of a series of thirty-five speci- 
mens from Trinidad.

The color of this species is exceedingly variable. In the 
pallid forms the head, rostrum, antennae, legs, posterior 
disc of the pronotum, scutellum, clavus and corium are 
identical in color with the same parts of the body of D. 
howardi Ballou, which they also approach in size. They 
may be distinguished from the latter species by the rela- 
tively narrower anterior black margins to the abdominal
