entire, distinct, the marginal punctures obsolete ; lateral stria strong, sub- 

 entire, straight and somewhat crenulate, especially along the transverse apex ; 

 ante-scutellar stria extremely short, punctiform. Elytra transverse, one-half 

 longer than the prothorax, and, at the middle, rather more than one-fifth 

 wider ; sides evenly and strongly arcuate ; intlexed flanks flattened and feebly 

 punctate posteriorly, the single stria much coarser in the flattened area ; mar- 

 ginal series of distant punctures obsolete ; interstrial row subobsolete ; oiater 

 humeral short, oblique, feeble ; inner rather long, fine, extending beyond 

 basal third ; subhumeral rather coarse, subentire, feebly arcuate basally, 

 with a fine oblique inferior appendage only ; dorsals coarse and deep, the 

 first four entire, the fourth arcuate at base halfway to the scutellum ; fifth 

 and sutural finer, short, equal and apical ; surface near the base of the first 

 dorsal distinctly and broadly impressed. PiopijgkHum rather coarsely evenly 

 and very densely punctate, the pygidium strongly, very densely so toward 

 base, gradually more finely and obsoletely toward tip. Prosternal lobe broadly 

 rounded, subtransverse and strongly margined at apex ; mesosternal emargi- 

 nation very feeble and broadly rounded. Anterior tibiae arcuate externally, 

 and with about six small spiculiform teeth ; spinules of the posterior small 

 but rather close-set. Length 4.5 mm. ; width 3.6 mm. 



New York (Catskill Mts.). 



Readily distinifuishable by the broadly oval form with subin- 

 flated elytra, and by the pronotal sculpture; from marginicoJlia 

 it may be known by the entire and basally arcuate fourth dorsal 

 stria and verj' densely punctate propygidium. 



Group Abbrevialus. 



Resembles the preceding, but with the subhumeral stria greatly 

 abbreviated, interrupted or obsolete. The anterior tibiae are 

 minutely serrulate externally, sometimes almost mutic. The two 

 species here described ma}- be known from any of the others by the 

 coloration, which is similar to that of militaris: — 



H. electllS n. sp. — Oblong-oval, thick, con vex, the punctulation extremely 

 minute and sparse, the pronotum strongly, densely punctate along the basal 

 margin, gradually more nanowly to the middle ; elytra red and black. Head 

 feebly punctulate, very broadly and feebly concave anteriorly ; stria entire, 

 the apical part wide and feebly sinuate. Prothorax twice as wide as long, the 

 sides feebly convergent and nearly straight to beyond the middle, then more 

 rapidly rounded ; fine marginal stria entire ; three marginal punctures very 

 feeble ; outer lateral stria strongly hooked at apex, extending only to apical 

 third ; inner subentire, nearly straight, very distant from the sides anteriorly, 

 gradually approaching the edge posteriorly; ante-scutellar stria very short, 

 strong. Scutellum small, equilateral. Elytra wider than Jong, not quite one- 

 half longer than the prothorax, and, at basal third, scarcely perceptibly
