May 28, 1904, collected by W. S. Blatchley, Purdue University (W. S.

Description: Rostra of both sexes black, closely but not roughly 
punctate and squamose behind the antennal insertions; moderately 
curved, polished, finely punctate before the antennal insertions in the 
female; stout, slightly curved, strongly punctate before the antennal 
insertions in the male. Head black, shining, sparsely punctate. 
Antennae rufopiceous, the second funicular segment much longer than 
the third. Prothorax piceous, broadly rounded at the sides, moderately 
narrowed and slightly constricted behind the apex; disk evenly 
covered with rounded punctures, no smooth median line present; scales 
of the disk sparse, rather linear, yellowish white; prosternum deeply 
emarginate, moderately concave. 
Elytra piceous, the intervals thinly covered with elongate-ovate 
scales, some of which are white, while others are smaller and light tan 
in color. Underside of the thorax and abdomen covered with small 
elongate-ovate white scales. Femora piceous, strongly clavate, 
covered with elongate-ovate white scales. Tibiae piceous, thinly 
covered with linear yellowish white scales; hind pair noticeably ex- 
panded at the apices. Tarsi reddish brown, the fourth segment 
extending well beyond the third, the claws connate near the base, 
moderately divergent. Internal sac of the male genitalia covered 
with large, heavy spines; spiculum gastrale distinctly hooked at the 
anterior end (figure 95).
