AMERICAN COLEOPTERA. 273 



inwardly, its width more than twice its length ; eighth joint nearly as long as 

 the width of the seventh, slightly increasing in width in basal third, then sinu- 

 ately sub parallel to apex, apical angle a little obtuse; ninth joint fully as long as 

 the eighth but narrower, fully four times as long as wide, outer edge broadly 

 arcuate, inner edge sinuate, tip moderately acute. In the female the seventh 

 joint (fig. 2) is less than one-half wider than long and nearly of the form of an 

 isosceles triangle; the eighth longer than the width of the seventh and scarcely 

 sinuate internally; ninth relatively a little less elongate than in the male and 

 not or only very feebly sinuate on its inner side. Eyes rather small, nearly 

 divided, scarcely differing in the sexes; the front about oue-half wider than 

 their longest diameter. Head moderately closely punctate. Prothorax rather 

 sparsely finely punctate at middle, the punctures becoming somewhat coarser 

 and closer at sides, where they are separated by more than their own diameters. 

 Elytral punctures coarser than those of the pronotum, irregularly placed with 

 but faint evidences of serial arrangement, except between the lateral stride, sepa- 

 rated on the average by about twice their own diameters. Metasternum coarsely 

 closely punctate'; ventral segments closely but less coarsely punctate than the 

 metasternum. Fifth segment as long as the two preceding united; the sutures 

 slightly arcuate at middle. Length 1.75-2.25 mm. 



Our commonest and most widely distributed species. The fol 

 lowing localities are represented in the material at hand : All the 

 New England States, New York, Pennsylvania, New Jersey, Dis- 

 trict of Columbia, North Carolina (Black Mountains), Ohio, Indi- 

 ana, Illinois, Wisconsin, Michigan, Missouri, Kansas, Louisiana, 

 Texas (Columbus), Arizona (Oracle and Santa Rita Mountains). 



6. C. Itluiifliardi n. sp.— Similar in form to oculata, but a little smaller 

 and with finer closer punctuation. Pubescence yellowish gray. Terminal joint 

 of maxillary palpus (fig. 6) about one-half longer than wide, the outer edge 

 rather strongly oblique, the inner angle rounded. Terminal joint of labial pal- 

 pus (fig. 7) fully one-half longer than wide, the outer edge moderately oblique. 

 First joint of antennal club in the male (fig. 5) less produced inwardly than in 

 oculata, its width barely twice its length ; terminal joint a little sinuate on its 

 inner side, nfiiking it appear somewhat arcuate, the apex pointed. Eyes widely 

 separated, nearly divided, not differing appreciably in the sexes. Front vaguely 

 longitudinally costate at middle. Length 1.5-2.1 mm. 



Described from a series of five examples taken at Tyngsboro, 

 Massachusetts, by Mr. Blanchard, to whom it gives me great pleas- 

 ure to dedicate the species With these I have placed a Michigan 

 (Detroit) specimen in the Hubbard and Schwarz collection, which 

 is quite surely identical, and a small series from Oregon (National 

 Museum collection, Koehele). I am not entirely certain that these 

 last are identical with the Massachusetts types, but can find no dif- 

 ferences of moment. The Oregon examples have hitherto passed
