with mouth parts, antennal scape, and legs reddish brown to piceous; 

 antennal club grayish black except the apical segment which is tan; 

 ventral parts of the thorax with scattered coarse punctm-es, each 

 bearing a reddish seta; surface finely alutaceous between punctm-es 

 except medially on the metastcrnum where it is smooth and finely 

 punctate; abdominal segments alutaceous and, except for the first 

 segment, with a row of punctures across their bases, most of the punc- 

 tures bearing short reddish setae; last abdominal segment apically red- 

 dish brown, broadly emarginate to receive the pygidium. Forelegs 

 not noticeably larger than those of females, similar to male major of 

 velutinus except that they are not as obviously alutaceous on the outer 

 surface. Middle and hiad femora with scattered coarse and fine 

 punctures, the coarse ones often bearing setae. 



Male minor. — Paratype, length 6.0 mm., width 3.6 mm. Differ- 

 ing from the t3rpe in the following respects: Dorsal color reddish 

 black; head similar except that the clypeus is scarcely reflexed anteri- 

 orly and the carina of the vertex is higher. Pronotum similar in 

 outline, but less convex and with the pronotal protuberance reduced 

 to a flat shelf barely extending over the back of the head, the protu- 

 berance with parallel sides and a truncate anterior margin, the deep 

 fossae on each side of the protuberance in the male major here reduced 

 to shallow indentations with a few tubercles and punctures (in one 

 damaged male minor the thoracic protuberance is so reduced that the 

 pronotum is similar to that described for the female). Elytra, pygid- 

 ium, and ventral sm-faces, except for a lighter color and few more 

 tubercles on the elytral intervals, identical with the male major. 



Allotype. — Female, length 7.0 mm., width 4.2 mm. Differing 

 from the male major in the following respects: Surface of head heav- 

 ily, rugosely punctate; clypeus scarcely reflexed, more sharply, nar- 

 rowly emarginate anteriorly; clypeal cariua evident and entire from 

 side to side; frontal carina at least twice as high as in male major, 

 bowed posteriorly near the middle. Pronotum differing mainly in 

 the shape of the pronotal protuberance which is reduced to a large 

 median tumosity rising abnost vertically above the anterior pronotal 

 margin; a smooth gi'oove on either side of the tumosity representing 

 the fossae of the male major, the anterior edge of the tumosity broadly 

 arcuate and approximately the same width as the carina of the 

 vertex; tubercles of pronotum more pronounced than in male, with 

 the basal setae shghtly longer. Elytra similar, except that the tu- 

 bercles of the intervals appear slightly larger. Pygidium more convex 

 and apicaUy less alutaceous than in male major; ventral surfaces 

 with the setae and punctures more conspicuous; last abdominal 

 segment lighter in color along its posterior margin, not emarginate 

 to receive the pygidium. Foretibia of the same length as in the
