long, somewhat robust, one-half as long as the body, the joints equal in 

 length throughout, the intermediate strongly obconical and nearly twice as 

 long as wide, the third very long, cylindrical and slightly longer than the 

 fourth. Prolhorax two-thirds to three-fourths wider than long, somewhat 

 parabolic and strongly rounded at apex, the sides becoming parallel and 

 distinctly arcuate in basal half to two-thirds, the angles nearly right, not 

 rounded ; base transverse, the sinuations rather narrow and distinct ; disk 

 scarcely impressed, very finely and sparsely, somewhat feebly punctate. 

 Elytra four times as long as the prothorax and subequal to the latter in 

 width, gradually very acutely ogival toward apex, the sides parallel and 

 scarcely visibly arcuate ; disk with feebly impressed series of punctures, 

 which are rather coarse and distinct toward base, but almost completely 

 obsolete toward apex, the intervals minutely very sparsely punctate, tliese 

 punctures becoming rather coarser and more asperate toward apex. Abdomen 

 minutely, sparsely punctate throughout. Z^(/s slender ; femora rather robust, 

 sparsely punctate ; basal joint of the hind tarsi unusually long, fully one-half 

 longer than the remainder. Length 7.0 mm. ; width 2.6-2.8. 



Michigan. 



The species above described is not likely to be confounded with 

 any other, being distinguishable by its long antennae with strongly 

 obconical joints, the third a little longer than the fourth — which is 

 unusual in this section, — its larger eyes and incomplete elytral 

 series. It also differs in its very fine, extremely sparse pronotal 

 punctuation. The two specimens before me are apparently females. 



5 H. punctulatus Lee— Proc. Ac. Phil., 1859, p. 78.— Oblong-oval, 

 moderately convex, polished and pale rufo-testaceous throughout, the pubes- 

 cence line, short, subrecumbent, pale but rather sparse and not conspicuous. 

 Ilead rather large and strongly convex, somewhat coarsely, sparsely punctate, 

 the eyes small, separated by two-fifths more than their own width ; antennae 

 rather short and robust, distinctly attenuate toward apex, but little more 

 than one-third as long as the body, the intermediate joints somewhat feebly 

 obconical, the third and fourth subequal. Prothorax strongly transverse, 

 about twice as wide as long, the apex broad and subtruncate, the base trans- 

 verse, broadly, feebly arcuate in the middle ; sides broadly arcuate and con- 

 vergent in apical two-fifths, thence nearly parallel to the basal angles which 

 are obtuse and rather blunt; disk scarcely at all impressed, finely, rather 

 densely punctate, the punctures separated by about twice their own diameters. 

 Elytra nearly five times as long as the prothorax and rather distinctly wider, 

 somewhat abruptly ogival in apical third ; sides parallel and just visibly 

 arcuate ; humeri rounded and oblique externally, but not exposed at base ; 

 disk with feebly impressed series of fine, rather approximate punctures, the 

 intervals minutely, confusedly and* somewhat sparsely punctate. Abdomen 

 minutely, rather feebly and sparsely punctate. Length 6.3 mm.; width 2.6 mm.
