THE CANADIAN ENTOMOLOGIST. 309 



rounded, disk notably depressed before the scutellum. Surface, when de- 

 prived of concealing indument, granular from the density of the punctua- 

 tion, and with a polished dorsal line , elytra convex, inflated at middle, 

 measured across the convexity as wide as long, roundly contracted from the 

 middle to base where the width equals that of the thorax. posteriorly strongly 

 declivous, deeply and widely striate, punctures large and distant, intervals 

 convex and narrow with a crenate appearance ; legs granulato-punctate 

 and coated like the head and thorax. The punctures contain exceedingly 

 short curved bristles visible only when sought for. Length, .08-10 inch. 

 Described from 4 examples. Easily known from all our species as yet 

 described, by the absence of erect setae and patches of scales on the elytra, 

 as well as more globose form. Occurs near Allegheny, Pa., in April, 

 about beech trees (Fagus ferrnginea), under stones where it has hiber- 

 nated, but is not often found. 



Pachybci) is strigapuiutus. — Bariform, black, shining, tarsi piceous. 

 Beak polished, slender, long, arcuate ; that of $ punctate at base and 

 finely irregularly lineate to apex when carefully viewed ; that of ? 

 scarcely longer, punctate and lineate at base to the insertion of the an- 

 tennae ; first joint of antennae nearly three times longer than second, 

 which is one-half longer than thiid, 3 to 7 equal in length but increasing 

 in thickness, the 7th rather suddenly ; thorax wider than long, convergent 

 from base forward, suddenly constricted at apex f.^r the insertion of the 

 head, base with a long scutellar-lobe on each side of which it is slightly 

 sinuate, finely, closely strigate in longitudinal wavy lines, scatteringly 

 punctured especially near the apex, a fine median line from apex to 

 scutellum ; elytra a little wider than the thorax, twice longer, widest at 

 middle, finely striate, stria: not obviously punctured, intervals flat, 

 uniseriately punctured, each puncture containing a white scarcely project- 

 ing hair or seta ; underside, pro- and meso-thorax and legs rather coarsely 

 closely punctured, venter more finely, white seta; of the punctures more 

 conspicuous than above ; tibiae roughly striate and punctured. The o* 

 has an acute tubercle before the anterior coxae, in one example a spine as 

 in some Centrinus; the anterior coxae are not widely separated, the 

 prosternal cavity is well marked but not incised. Length, .12 to .15 inch. 

 Characterized from 3 $ and 3 $ examples. Occurs in May and June on 

 Crataegus, but not abundantly. 



Balaninus confusor. — Form, colour and vestiture the same as in B.
