postmedian spots paler. Integuments polished throughout. Antennae scarcely 

 infuscate apically. Head margined in front. Punctuation of head and thorax 

 fine, not very* close; elytra more coarsely and closely punctate. Body beneath 

 rather strongly and not very closely punctate, the punctures coarser on the 

 coxal plates as usual. Length 2.6 mm.; width 1.4 mm. 



The type was collected in Alameda Co., California by Koebele. The 

 specimen is, I think, a male, though the tarsi are only very moder- 

 ately dilated. A second specimen is from Dalles, Oregon. 



This litle species is by the margined front allied to those which pre- 

 cede, but is distinctly less convex both above and beneath, and has 

 the moderately elongate oval form of most of the species which follow. 



C. laccophilinus Lee. 



Ovate, pointed behind, moderately convex, rufocastaneous, coxal plates and 

 base of abdomen sometimes infuscate. Integuments sparsely rather finely 

 punctate, strongly shining in the male, alutaceous and opaque and more finely 

 punctate in the female. Length 2.8 to 3.1 mm.; width 1.65 to 1.75 mm. 



Described from Detroit, Michigan ; known to me also from Tyngs- 

 boro, Mass., Peekskill, N. Y. (Sherman), and Indiana (Blatchley.) 

 It is also recorded by Smith in the New Jersey List. 



This species is similar in many respects to the next, but is a little 

 larger, broader and more convex, and with less inequality in size of 

 punctures. The front and middle tarsi are very distinctly wider in 

 the males than in the females, the disparity being much less marked in 

 sylvaiius. 



C. sylvanus Fall. 



Form rather narrowly ovate, widest before the middle, moderately convex, 

 glabrous, both sexes shining; color castancous, the antennae legs and under 

 side of head and prothorax brighter rufous. Head and prothorax finely 

 sparsely punctulate, the latter more strongly and closely so along the front and 

 rear margins. Elytra widest a little behind the base, sides continuous in out- 

 line with the prothorax; punctuation not very close, consisting of intermixed 

 moderately coarse and much finer punctures. Metasternum, coxal plates and 

 sides of the basal ventral segments sparsely punctate, the punctures gradually 

 diminishing in size from front to rear. Front and middle tarsi of male only 

 moderately dilated, a little narrower in the female ; claws small and slender, 

 unmodified in the male. Length 2.5 to 2.7 mm.: width 1.35 to 1.45 mm. 



New York (Peekskill Sherman.) 



Nearly allied to laccophilinus but smaller, narrower and less convex 

 (not "more convex" as was stated by mistake in the original descrip- 

 tion), and with less dilated male tarsi, the sexual difference in this 

 respect not very marked. 



C. turbidus Lee. 



Regularly oval, moderately convex, widest at middle, above dull yellowish to 

 brownish or piceotestaceous, without markings ; the head, thorax anteriorly, and 

 side margins of elytra a little brighter in color; integuments polished in both
