entire, with two small and very distant internal punctures ; outer lateral 

 stria subentire, strongly hooked at apex ; inner strong, feel)ly sigmoid, gener- 

 ally somewhat abbreviated before the base ; ante-scutellar stria sliort but 

 deep. Scutellnm unimpressed, small, equilateral. Elytra one-half longer 

 than the prothorax, and, at basal third, distinctly wider ; sides arcuate ; 

 apex feebly oblique, five-sixths as wide as the base ; infiexed fianks coarsely, 

 sparsely punctured, with a single fine, nearly entire stria ; striae rather coarse, 

 the subhumeral slightly abbreviated at base ; ninth stria composed of small 

 remote punctures along the convex flanks ; inner subhumeral composed of 

 more closely spaced punctures between the subhumeral and first dorsal, nearer 

 to the former ; oblique humeral very fine and feeble ; first four dorsals sub- 

 entire ; fifth short, arcuate, occupying apical third ; sutural represented by 

 a series of coarse punctures from the apex to about the middle. Propjiyidium 

 coarsely evenly and rather closely punctate throughout, the interspaces 

 minutely, sparsely punctate ; pygidium strongly, densely punctate. Pro- 

 sternal lobe truncato-sinuate, with broadly rounded angles, finely margined, 

 deeply but not very coarsely punctate laterally. Mesosternura deeply, broadly 

 sinuate in median third, the marginal stria entire. Anterior tibise rather 

 closely 5-dentate, sometimes with a minute sixth denticle basally. Length 

 5.5-6.5 mm. ; width 4.2-5.0 mm. 



Yirginia (Fredericksburg). 



In view of the variations noticed in d^purator, I am unable to 

 estimate the true value of the truncate yjrosternal lobe in this spe- 

 cies ; it is however perfectly similar in the three specimens before 

 me. The two minute punctures along the fine marginal stria of 

 the pronotum are constant in size and position in these tj^pes. 



H. plllto. — Rather narrowly oval, convex, polished, the punctules remote, 

 scarcely stronger on the head but becoming distinct punctures toward the 

 inner stria and basal angles of the prothorax. Bead feebly impressed at the 

 middle of the epistoraa, the frontal stria distinct, subentire, with an acutely 

 reentrant angle at the middle. Prothorax quite distinctly less than twice as 

 wide as long; sides moderately convergent and broadly arcuate from base to 

 apex ; fine marginal stria entire, with two minute remote internal punctures ; 

 outer lateral stria straight, subentire, hooked at apex ; inner subentire, coarse, 

 slightly uneven ; short ante-scutellar stria very deep. Elytra nearly as long 

 as wide, one-half longer than the prothorax, and, before the middle, slightly 

 wider ; sides feebly, evenly arcuate ; apex distinctly oblique and narrower 

 than the base ; inflexed flanks concave behind basal third, coarsely and 

 rugosely punctate ; lateral c(mvexity with an entire series of even remote 

 punctures ; subhumeral nearly entire, the series of punctures between it and 

 the first dorsal almost completely obsolete ; humeral stria distinct ; there is 

 also a short basal stria external to this and the usual internally oblique striole 

 from the humeral angles ; first three dorsals strong, entire ; fourth abbreviated 

 more or less before the middle ; fifth represented by a few subapical punctures ; 

 sutural short, subapical. Propjjgidiam and pygidium densely evenly and not
