HANCOCK 4:^ 



inserted considerably below and in advance of the eyes about 

 one-third the breadth of one of them, the first joint large, the 

 second round and diminutive, the remaining ten or eleven 

 articles becoming extremely attenuated. Pronotum foliaceous, 

 strongly angulose, the portion above being thinned out and 

 partially translucent when held against the light; the dilated 

 opaque portion of the pronotum below divided by a strongly 

 arcuate line and highest at the middle; sides of the pronotum 

 distinctly veined and punctate. Dorsum in profile elevated 

 into an angle a little behind the middle, in front of the angle 

 sloping forward nearly straight over and beyond the head; the 

 part before the angle a little sinuate, at the antero-produced 

 portion suddenly truncate and bisinuate; the short horizontal 

 inferior margin straight, anteriorly angulate (two millimeters 

 in length), extending beyond the head; behind the angulate 

 dorsal summit a little more precipitously declined, subcon- 

 caved, posteriorly marked by slight sinuations and the apical 

 extension backward, forming the posterior process, provided 

 with a prominent tooth near the apex, which here projects 

 backward a little farther than the inferior marginal apex, and 

 scarcely or about as far as the angulate apex of the posterior 

 femora. Viewed from above the dorsal median margin is 

 sulcate; the humeral angles are obliterated ; the lateral carinae 

 exquisitely modified into veins. Elytra and wings wanting. 

 The posterior angle of the lateral lobes small, subangulato- 

 truncate behind, with a small, deep, subrounded sinus above; 

 the inferior margin of the lobes scarcely at all laterally 

 deflected; toward the apex the inferior lateral margin of the 

 pronotum very little but broadlv convexo-concaved. Anterior 

 femora narrow, above carinate, below lobate at the anterior 

 third, and a very small secondary lobe just following; middle 

 femora slender, both margins very slightly lobate near the 

 extremity; posterior femora slender compressed, superior 

 marginal carina a little beyond the outer half suddenly reduced ; 

 genicular tooth strongly angulate produced, external femoral 

 paginje scabrous, between the superior marginal carina and 

 the next one below three or four enlarged elevated papillate 

 eminences.
