NORTH AMERICAN COLEOPTERA. 275 



the sides the two outer strife, are sometimes faiutly indicated bj' coarser puuc- 

 tures. Body beneath piceous black, opaque. Legs piceous or brown. Posterior 

 femora finely strigose, sparsely punctate, middle and front femora densely punc- 

 tate, except at apical third. Length .10 — .12 inch. ; 2.5 — 3 mm. 



, rrosternum simple, mesosternuni plane, without trace of any 

 protuberance. 



The above description will be found to differ in some points from 

 that based on the unique in my former paper. That now proves to 

 have been an immature specimen, hence the unfortunate trivial name. 

 Superficially, it greatly resembles digestus, and it is only by an ex- 

 amination of the niesosternum that the two can be separated. As 

 the protuberance in digestus is sometimes either a short, transverse 

 ridge, or even a small tubercle, it may be pos.sible that more material 

 will show the desirability of uniting the two species. 



Occurs in Oregon and Washington. 



v. iiifuscatus Mots. — Eather broadly elliptical, convex, fusco-testaceous or 

 ochraceous, head black, usually with a pale spot in front of each eye, suture of elytra 

 narrowly iufuscate. Anteinise 9-jointed, testaceous, club dark. Head usually 

 closely punctulate. Thorax pale piceo-testaceous, with a rhomboidal darker 

 space at middle, an arcuate space each "side less dark (PI. iv, fig. 16), disc dis- 

 tinctly and moderately closely punctate, a little coarser at the sides, no basal 

 marginal line. Elytra piceo-testaceous or ochraceous, the suture narrowly 

 darker, the punctuation a little coarser, but less close than on the thorax, with- 

 out evidence of linear arrangement. Body beneath piceous, opaque. Legs pi- 

 ceous, tibisE and tarsi usually paler. Femora of all the legs densely punctulate, 

 pubescent and opaque, except for a short distance at apex. Length .08— .10 inch. ; 

 2—2.5 mm. 



Prosternum simple, mesosternuni with a transverse ridge acutely 

 elevated at middle. Maxillary palpi short and stout, the pseudo- 

 basal joint nearly as thick as in dissimilis. 



As a rule the legs and antennal club are dark in color, but speci- 

 mens have been seen with both comparatively pale. 



At first sight this insect resembles .some of the forms of PhiL 

 nehulosm, although rather broader and more convex. The above 

 description applies es|)ecially to specimens clean and free of discolor- 

 ation. Many have merely a general brownish color until properly 

 deprived of grease, while in others the dark spaces of the thorax 

 form an indefinite cloud. 



H. feminalis Lee. is one of those latter forms in which the punc- 

 tuation of the surface is a little less distinct. Similar specimens 

 occur in California. 



H. castaneus Lee. is founded on dark, discolored specimens, with 

 the greater portion of the disc of the thorax piceous, merely the
