Similar in structure aiul habitus to inornatus, exccjit as follows: Second 
antennal segment (fig. dGc) suddenly enlarged in aj)ical third. Pronotal 
margins (fig. Stkl) less broadly ex])anded and rather irregular in outline, the 
teeth very uneven. 
cT (fig. 3()b). Fifth ventral segment slightly longer than sixth; genital 
segment very strongly convex, the lobes decidedly longer than in tnorndl us.

This species, while closely related to inornolKS, may be readily 
recognized l)y the strikingly different aidennal structiii'e and 
the pronotal characters.

Description. — Black, Hnely granulate; posterodateral margins of pronotum, 
narrow ])Osterior margins or at least ajiical angles of connexival segments, 
and inner margins of genital lobes, reddish yellow; basal expansion of corium 
and narrow sides of scutellum sometimes obscurely pale; rostrum and legs

Head longer than broad (40 to 32), longer than jironotum (40 to 32); tylus 
long, strongly conpiressed, enlarged somewhat toward base; inijiressions of

s])ines rather stout, conical, moderately divergent, the lateral tooth obsoles- 
cent; postocular tubercles very low, rounded; eyes prominent, substylated; 
antennae (fig. 37c) moderately slender, almost as long as heail and jironotum 
together (70 to 7.5), the first .segment reaching middle of tylus, the second in 
length slightly more than eipial to width of head including both eyes; rostrum
