rounded, less narrowed hehiud than in front, hind angles obliquely truncate 

 above and with the carina not reaching the subniarginal line, angles produced 

 below. Elytra punctate striate intervals feebly convex, punctulate. sides rounded, 

 ajiex narrower, normally with two small pale yellow si>ots before the middle and 

 two before the apex, either pair may be obsolete or wanting, the posterior are 

 sometimes transverse and reach both margin and suture, the humeri may have 

 a small spot, or the ante-median spot may be extended forward obliquely to the 

 humeri. In one 9 'Massachusetts., a vitta extends from the humerus obliquely 

 backward and inward narrowly one-third, then is dilated inwardly for another 

 third and then directed both ways so as to reach both margin and suture, apex 

 black. Body beneath shining, punctulate with coarser punctures intermixed, 

 except on the sides of the prothorax : submarginal lines reaching the middle of 

 the thorax or beyond, cariniform at base, impressed anteriorly, exterior angle of 

 side pieces acute, produced beyond the base of the pronotum. not sinuate at base 

 inside the angle, post coxal process ra'her short, margined behind, and feebly 

 ascending : hind coxal plates with posterior margin transverse, not dilated be- 

 hind. Legs of the same form as in the previous species, black varied with yel- 

 low. Length j>2-.33 inch. ; 6-8 mm.

The only Massachusetts specimen seen was found on the sea-shore, 

 and I suspect it does not occur inland east of the great lakes. In 

 the two preceding species there is not a notable difference in size in 

 the sexes, but here the $ is frequently much larger. It differs es- 

 pecially from fene-itratm by the more elongate form, more acuminate 

 behind, by the greater convexity of the thorax and the less dilated 

 hind coxal plates. Candeze uses the truncation of the hind angles 

 of the prothorax, in his synoptic table, to distinguish one of the va- 

 riations of this species, but does not allude to it in the description. 

 The type of Dejeanii Lee. is a S of tliis species. 



4. C bifasciatns n. sp. — Black, opaque, clothed with yellowish pubescence, 

 with two undulating yellow fasciae across the elytra. 9 robust, very convex, 

 legs varied with rufous. Antennfe of the 9 slender, feebly serrate, short, two- 

 thirds the length of the head and thorax. Head feebly convex with frontal 

 margin finely elevated and broadly rounded, the lateral oblique carina present, 

 densely punctured with with fine and coarse punctures. Thorax very convex, 

 as wide as. or wider than long, densely finely punctate and with numerous regu- 

 larly disposed larger punctures distant from one another three or four times 

 their breadth, sides strongly rounded and narrowed in front, obliquely less nar- 

 rowed behind, hind angles obliquely truncate above, produced beneath, basal 

 plicfe moderately long, lobe bisinuate. disc very faintly longitudinally impressed, 

 carina not confluent, with submarginal line, though sometimes barely reaching 

 it by a minute deflection. Elytra wider than the thorax, convex, sides broadly 

 rounded and narrowed from behind the middle to tip, strongly punctate striate, 

 intervals ver>- convex, becoming more so towards the apex, rather densely punc- 

 tulate, a median or slightly ante-median fascia extending from the suture out-
