d’. The apical margin of the terminal genital segment not 
toothed or angulate at the sides above the points of 
insertion of the claspers. 
c*’, The spines very long, acuminate, and divergent ; elytra 
moderately long, the corium and membrane dark : 
body robust we ee ee 
d°®, The spines very much shorter, divergent; elytra rela- 
tively longer, the corium with some of the nervures 
partly ochreous (rarely in great part ochreous), the 
membrane blackish; legs rather slender: body narrow 
(3), broader ( ¢?) soe ee . 
b°, Membrane hyaline, with the base only dark ; corium blackish, 
the nervures partly or entirely pale; ¢ with the apical 
margin of the terminal genital segment toothed at the sides 
above the points of insertion of the claspers . soe 
b*. Posterior lobe of the pronotum rugose; apical margin of the 
terminal genital segment of ¢ broadly truncate between the 
spines a 
d'". Pronotum with the base deeply sinuate on each side near the hind 
angles, the posterior lobe smooth; ¢ claspers angularly dilated 
on the inner side about the middle, the spines long and feebly 
divergent: body robust, the legs stout 
? with the outer apical angles of the first genital (terminal dorsal) 
segment deflexed and not forming a continuous outline with the 
coniexival margin; ¢ with the apex of the last genital segment 
produced into a short process in the centre and armed with two spines.

e". @ with the two genital spines upwardly curved and obliquely 
divergent. 
e"". Pronotum partly rufous (in the Mexican specimens usually with 
two transverse black fascie, and the basal margin narrowly 
pale towards the sides) ; the corium (except in dark vars.) rufous 
or reddish-ochreous, with the apical margin narrowly ochreous ; 
connexival margins, at most, very narrowly pale. . . 
f’”. Pronotum black, with reddish or pale basal margin; corium 
obscure rufo-piceous ; connexival margins more broadly pale .

laterally extended. 
g'". Ventral segments flavous, with the sutures very narrowly black : 
species larger, more robust, and more brightly coloured. .
