distinct ; disk scarcely impressed, somewhat coarsely, very densely punctate, 

 tlie punctures circular and almost absolutely in contact, but not polygonally 

 crowded. Elytra three and one-half times as long as the prothorax and about 

 one-fifth wider, rather obtusely ogival in apical third, the humeri very slightly 

 rounded to the base of the prothorax ; sides parallel and nearly straight in 

 basal two-thirds ; disk with rather deeply impressed strise of somewhat coarse, 

 close-set, almost perforate punctures, the intervals somewhat convex, very 

 minutely, rather sparsely punctured. Abdomen finely, sparsely punctate. 

 Legs slender, the basal joint of the hind tarsi distinctly longer than the 

 remainder. Length 6.8 mm. ; width 2.3 mm.

This species is not at all closely related to any other, the strongly 

 shining, deeply striate, minutely punctate elytra, coarsely, densely 

 punctate pronotum, long antennte and oblong, subdepressed form, 

 at once distinguishing it. 



35 H. inaeqiialis n. sp. — Oblong, parallel, strongly convex, the elytra 

 polished, dark piceo-castaneous, the under surface, legs and antennse paler, 

 rufescent ; pubescence rather long, more than usually erect, not very dense. 

 Head coarsely, sparsely punctate between the eyes, more finely, densely so 

 anteriorly; eyes moderate, separated by four-fifths of their width ; antennse 

 rather stout, gradually, distinctly attenuate, fully two-fifths as long as the 

 body, joints five to eleven gradually decreasing in width and just visibly 

 increasing in length, the former two-thirds longer than wide, strongly obconi- 

 cal, the tenth much more than twice as long as wide, third very distinctly 

 longer than the fourth. Prothorax short, three-fourths wider than long, the 

 apex two-thirds as wide as the base, almost transversely truncate, the base 

 transveise, the median portion broadly, distinctly arcuate ; sides broadly 

 arcuate and strongly convergent anteriorly, very slightly convergent and 

 nearly straight in basal two-fifths, the angles rather distinctly obtuse but not 

 at all rounded ; disk not impressed, convex, very coarsely, extremely densely 

 and not very deeply punctate, the punctures in contact and somewhat poly- 

 gonally crowded. Elytra nearly four times as long as the prothorax and just 

 perceptibly wider, the apex gradually, evenly ogival, the humeri feebly, 

 obliquely rounded externally to the prothoracic base, the sides parallel and 

 nearly straight; disk with extremely feebly impressed series of small but 

 deep, close-set and almost perforate punctures, which are slightly oblong; 

 intervals highly polished, minutely, sparsely punctate. Abdomen minutely, 

 sparsely punctate, the anterior portions of the body coarsely so, the prosternum 

 and propleurse extremely densely so. Legs moderate in length, rather densely 

 pubescent, the femora slightly robust ; basal joint of the hind tarsi subequal 

 in length to the remainder. Length 7.0 mm. ; width 2.8 mm.

 its oblong, unusually convex form, very coarse, dense prouotal and
