desinente, lateral! basi abbreviata, pone oculos iaterrupta ; elytris 

 striis dorsalibus 1-4 integris, 5 et suturali apicalibus ; propygidio 

 postico transversim punctato, margine laterali anticoque laevi ; 

 pygidio punctato, margine postice la?vi. 

 L. ^ mill. 



Shortly oval, convex, black and shining ; the head, stria 

 strong and straight behind the mandibles, sinuous on either 

 side, with a median depression behind the stria ; the thorax 

 bisinuous on the anterior edge, marginal stria fine laterally, 

 but deeper from the anterior angle until it terminates behind 

 the eye, internal stria shortened at the base, feebly sinuous 

 at the sides, bent and interrupted near the anterior angle ; 

 the elytra, humeral strias wanting, except the oblique basal, 

 which is very fine, dorsal stride 1-4 complete, 3-4 somewhat 

 bent, 5 apical, nearly dimidiate, and parallel to the fourth, 

 5 shortened by one third of its length and posteriorly widens 

 from the suture ; the propygidium has a rather wide smooth 

 margin at its base and sides, with a transverse thickly and 

 rather coarsely punctured surface behind ; the pygidium is 

 similarly punctate, with a smooth posterior margin ; the 

 prosternum with large shallow punctures, anterior lobe clearly 

 marginate, keel narrow, smooth, and triangular at the base ; 

 the uiesosternum, anterior edge nearly straight, with a com- 

 plete marginal rather deep stria and a short stria at either 

 angle ; the anterior tibia has a strong apical tooth, obscurely 

 bifid, with 3 or 4 obtuse inconspicuous teeth behind it. 



The thoracic striaj and the marginate propygidium of this 

 species agree with those of //. Geslroi^ Sch. ; but //. cincti- 

 j^ygus is smaller and relatively broader, and has a very distinct 

 frontal depression. In //. latimargo, Sch., Icevimargo, Lew., 

 and pIa7iimargo, Lew., the propygidia are similarly margined, 

 but in all the American species the prosternum is bistriate.
