but flatter and not so robust, narrower at the base of the 
hemielytra, the eyes much larger and more prominent, and 
the head smaller. 
Eyes almost contiguous at their postero-interior angles, their 
interior lateral margins very curved, widely diverging towards 
the vertex, where the head is from six to eight times as wide 
as between the postero-interior ocular angles. Head and pro- 
notum smooth, shining, pale rufo-testaceous ; eyes reddish 
chestnut, irregularly bordered with black. Antenne: two 
basal segments madder-brown, two apical segments rufo- 
testaceous. 
Pronotum anteriorly somewhat rugose, with superficial 
spherical depressions, posteriorly very finely punctate; 
humeral angles acute, accentuated; lateral margins sinuate, 
ctirved posteriorly below the humeral angles, forming almost 
a continuous line with the lateral margins of the scutellum ; 
lateral margins distinctly and widely flattened anteriorly, the 
whole posterior half of the pronotum being elevated ; poste- 
rior margin not sinuate. 
Scutellum black, not pubescent; lateral margins very 
sinuate. 
Connexivum (1) rufo-testaceous, each segment narrowly 
black at the apex, or (2) entirely green. 
Hemielytra dark brick-red (or rich orange-yellow), with 
short, sparse, golden-yellow pubescence; a large irregular 
black blotch at the base of the corium and embolium ex- 
tending transversely and non-acuminately from the apex of 
the clavus to the golden-yellow lateral submargin of the 
embolium ; membrane dark red-brown, apical half black, this 
tint encroaching more or less upon the basal half. 
Pedes ruto-testaceous or greenish ; coxe blackish, posterior 
tarsal fringe blackish and golden pink; all the spines and 
spurs on the legs black ; unguiculi black; spur on inter- 
mediate tibiz blunt, subcylindrical, two or three rudimentary 
spurs nearer the base; tibize and tarsi with four or five long, 
black, stiff hairs inferiorly ; posterior femora with a double 
row of short spines inferiorly ; tibiz with short spines supe- 
riorly and inferiorly. 
Ventral surface: frons emerald-green, anteriorly suffused 
with rose; apical segment of rostrum black, remainder rufo- 
testaceous, marginally darker. 
Abdomen ruto-testaceous, densely furnished with blackish- 
green hairs; sternal hair-tufts golden pink.
