lantic regions, but angustum seems to be perfectly congeneric with 

 the west coast forms. I am somewhat doubtful in regard to 

 glohifer and parabolicum, which are not represented in the ma- 

 terial before me ; they appear to have the discal stria of the el3'tra 

 much more abbreviated than usual. 



A. angustum n. sp. — Narrow, elongate, convex and" moderately ventri- 

 cose, polished, impunctate and pale rufo-testaceous throughout ; pubescence 

 moderate in length and rather sparse, subdecumbent, Read very slightly nar- 

 rower than the prothorax, a littl e wider than long, the eyes well developed, 

 -convex, prominent, at about their own length from the base, the tempora much 

 less prominent, feebly convergent and broadly arcuate behind them ; occiput 

 feebly impressed at the middle ; fovese deep, slightly pubescent, just behind 

 the middle, separated by fully % of the total width, the connecting impression 

 shallow and angular in form, the antennal prominences strongly tumid ; an- 

 tennae % longer than the head, the last joint elongate, gradually ogival and 

 almost as long as the preceding five joints, the tenth 23^ times as wide as long, 

 slightly oblique and a little more developed toward the outer side. Prothorax 

 as long as wide, widest and moderately rounded near the middle, the sides 

 broadly and rather deeply sinuate thence to the base ; surface convex, the lat- 

 eral fovese not very large but deep and subpubescent, connected by a deep 

 transverse groove which is posteriorly enlarged at the middle. Elytra almost 

 as long as wide, very convex, % longer and fully ,*5 wider than the prothorax, 

 the sides divergent from the rather widely exposed humeri, becoming strongly 

 arcuate behind ; basal fovese two in number ; discal stria fine and extending 

 almost to the middle. Abdomen about as long as the elytra and slightly nar- 

 rower, the sides parallel and feebly arcuate ; basal segment equal to the fol- 

 lowing, with two short basal carinse separated by }-^ of the discal width. Legs 

 moderate in length, the femora feebly and equally inflated. Length 1.2 mm. ; 

 width 0.4 mm. 



Pennsylvania (Westmoreland Co.). Mr. Schmitt. 



A number of specimens were sent to me under the name Trimio- 

 plectus paraboUcus, but according to the description and figure, 

 that species, the locality of which was not indicated by the au- 

 thor, must be quite different. The description is from the male, 

 in which sex the sixth ventral is broadly and feebly impressed, 

 and the oblong-oval flat enclosed pygidium of the seventh is much 

 smaller than in the Pacific coast forms. The female is less ven- 

 tricose than the male, with a slightly smaller head and very much 

 smaller eyes. 



A. 'bifOTeatum n. sp. — Elongate, the hind body wider, convex, polished, 

 subimpnnctate, the elytra minutely, subrugosely punctulate, rufo-testaceous 

 in color, the pubescence subdecumbent, rather short and moderately abundantr 

 Head small, very much narrower than the prothorax, fully as long as wide, the
