of the upper surface notably sparse, the second joint distinctly- 

 shorter than the fifth. Length (cf 9 ) 11.5-16.0 mm.; width 4.4- 

 5.9 mm. Rhode Island and Lake Champlain to Florida and west- 

 ward to Lake Superior, Colorado (Boulder Co.) and Mississippi; not 

 at hand from Texas. Seventy examples. [H. bicolor Fab., fannns 



Dej. nee Say] pennsylvanicus DeG. 



A Similar to pennsylvanicus but narrower in form and with the elytra 

 more elongate when compared with the combined head and pro- 

 thorax; antennae thicker and notably shorter, especially in the 

 female; prothorax rather less narrowed anteriorly and with the 

 large foveae decidedly deeper; elytra distinctly wider than the 

 prothorax, parallel, nearly two-thirds longer than wide, similarly 

 deeply striate and sparsely and irregularly punctured laterally; 

 hind tarsi (cT) much shorter than the tibiae, sparsely and finely 

 pubescent above, the first three joints decreasing uniformly and 

 rapidly in length, the second distinctly shorter than the fifth. 

 Length (cT 9 ) 14.0 mm.; width 5.4-5.6 mm. Utah. Three 



examples mormonicus n. subsp. 



Body smaller in size and narrower, piceous to black in color, rather 

 shining, the elytra (9) slightly opaculate; under surface rufous to 

 nearly black, the legs pale; head moderately large, the foveae un- 

 usually developed, deep; eyes prominent, the antennae slender; 

 prothorax a third wider than long, parallel, feebly rounded at the 

 sides, only slightly narrowing anteriorly, the apex evidently narrower 

 than the base; surface, side margins and basal bead as in pennsyl- 

 vanicus, the general facies more as in j 'ami us but with less coarse 

 though separated basal punctures; elytra two-thirds longer than 

 wide, throughout as in pennsylvanicus; hind tarsi very slender, 

 much shorter than the tibiae,, very sparsely and inconspicuously 

 pubescent above, the first joint much longer, the second equal to, 

 the fifth. Length (9 ) 13.0 mm.; width 4.6 mm.; North Carolina 



(Southern Pines). New York LeConte convivus Lee. 



15 Body elongate and rather narrow, the general habitus nearly as in 

 pennsylvanicus. Color piceous-black, the entire under surface and 

 legs bright testaceous and concolorous; mandibles, antennae and 

 trophi bright testaceous, the first black at the tips; head moderate, 

 with small and perforate foveae, the eyes well developed, and prom- 

 inent, the antennae (cf) slender, extending behind the thoracic 

 base; prothorax about a third wider than long, subparallel, the sides 

 broadly rounded, more converging apically, the apex narrower 

 than the base, which is transverse, rather finely but strongly mar- 

 gined throughout, the angles slightly obtuse and narrowly rounded 

 at their tips; surface as in pennsylvanicus and with very feeble 

 vague foveae, but with much finer lateral re flexed margin and with 

 finer punctures latero-basally; elytra fully two-thirds longer than 

 wide, slightly wider than the prothorax, parallel, the sides feebly 

 arcuate, the sinus feeble, the striae fine but deeply impressed, the 

 scutellar long, deep and free; intervals slightly convex, feebly alu- 

 taceous, 3-5-7 with minute and widely spaced, subserial punctures; 

 all the outer intervals with minute sparse and suffused punctulation,
