sexes; antennae with outer joints lightly infuscate. Head and thorax finely 

 sparsely punctate, a few coarser punctures along the base of the latter. Elytra 

 with a dual system of finer and coarser punctures, which is, however, not very 

 strongly marked, the disparity becoming quite feeble posteriorly. Body beneath 

 black, metasternum, coxal plates and sides of abdomen at base coarsely, not 

 densely punctate, venter elsewhere finely sparsely punctate; under side of 

 prothorax, epipleurae and legs pale. Length 2.7 to 3 mm.; width 1.5 to 1.75 mm. 



Described by Le Conte from Massachusetts. Crotch says more 

 specifically, "Boston." It occurs rarely at Tyngsboro, Mass., and other 

 Massachusetts specimens in my collection are labeled Westport, Berke- 

 ley and Fall River (N. S. Easton). I have also before me examples 

 from Vermont, Montreal, Can.; Winnipeg, Man. (J. B. Wallis), and 

 Ag. Coll., Miss. (H. E. Weed.) It is reported from Staten Island 

 (Leng), and from Indiana (Blatchley.) 



C. dispar Lee. (=dissimilis G. & H.) 



Moderately elongate, oval, dull yellow to brownish testaceous, head and thorax 

 commonly brighter rufotestaceous, the typical dorsal discal clouds feebly de- 

 fined on the elytra in the light colored examples, but scarcely at all evident 

 . in the darker specimens ; trunk black beneath ; integuments polished throughout 

 in both sexes; outer joints of antennae lightly infuscate, with their bases paler. 

 Head and prothorax finely sparsely punctate, the latter with a few coarser 

 punctures near the base. Elytra with conspicuously intermixed fine and much 

 coarser punctures over the greater portion of the disk, the punctures closer 

 and more nearly equal in size at apex. Metasternum, coxal plates and the 

 sides of the basal ventral segments coarsely punctate. Length 3.4 to 4 mm.; 

 width 1.85 to 2.15 mm. 



This species is widely dispersed in the northern United States and 

 Canada. Described from Lake Superior. Specimens before me are 

 from Esopus, N. Y. ; Phila Neck, Pa. ; South Haven, Mich. ; Evanston, 

 Ind. ; N. 111. ; Glencoe, 111. ; Rochester, Minn. ; St. Louis, Mo. ; Winni- 

 peg, Man. ; Kamloops, B. C. It is recorded also in the New Jersey, 

 District of Columbia and Iowa Lists. 



In some 30 or 40 specimens examined there are no obvious sexual 

 differences, the tarsi being narrow and of the female type in all, 

 though there can be little doubt that both sexes are present. 



C. compar sp. nov. 



Elongate oval, very similar in form and size to the preceding species, and like 

 that, varying in color from dull yellow or rufotestaceous to fuscotestaceous or 

 brownish, the elytra, however, without trace of nubilous markings which are 

 sometimes somewhat defined in dispar, antennae infuscate from about the 

 middle. Elytra with intermixed punctuation, the coarser punctures, however, 

 are smaller than in dispar, and the disparity is therefore less marked and is not 

 very evident except in the baso-sutural region. The males are polished, the 

 females may be either shining or dull, the latter as usual more finely punctate. 

 In the male the front and middle tarsi are distinctly broader, the second joint 

 rather conspicuously widest and triangular, the third joint about as long as 

 wide and very slightly wider than the basal joint, the anterior claw of the front
