184 HEMIPTERA-HETEROPTERA. 
abdomen in the male extends very little beyond the elytra; the fifth segment is 
subangularly dilated at the outer apical angles ; and the sixth segment is subparallel and 
produced on each side at the apex into a short rounded lobe, the apical margin being 
truncate in the middle, leaving the terminal genital segment very narrowly exposed. The 
abdomen in the female is gradually narrowed behind, and extends to far beyond the 
elytra; it has the terminal ‘genital segment produced into a long caudiform process, 
and the fifth ventral segment very deeply emarginate at the apex. The venter is 
obsoletely canaliculate down the centre in both sexes. ‘The head has a row of stout 
setiferous spines on each side beneath, both before and behind the eyes, those behind 
the eyes being partly fused and forming irregular bifurcate processes. The anterior 
femora ure only moderately incrassate and unarmed.

Two of the three described species of this American genus occur in Central America, 
It is chiefly recognizable by the row of stout setiferous spines on each side of the post- 
ocular portion of the head beneath, these being sometimes fused and forming irregular 
bifurcate processes. The anterior femora are strongly incrassate.and armed with two 
rows of short spines beneath.

Of this species, the type of the genus, we possess a pair from the “ tierra caliente ” 
of Chiriqui. The male, as in G. litegiosa, has the abdomen obtuse at the apex, the 
terminal genital segment being produced into a caudiform process in the female.

_ The types of this species are before me, and our figure is taken from one of them. 
G. tumidula, Stal, from Texas, is doubtfully distinct from G. litigiosa.
