1. D. sordida Say. 



Blackish brown, more rarely reddish brown, clothed above with 

 short erect or suberect hair, which is longer, denser, and more brightly 

 fulvous on the head, prothorax, and around the scutellum; shorter and 

 more grayish elsewhere on the elytra. Punctuation rather fine but 

 very dense throughout, the elytral costae obsolete or but feebly indi- 

 cated. Clypeus broadly sinuate emarginate, head with transverse 

 occipital smooth space. Sides of prothorax sinuate in front, the angles 

 prominent and acute; hind angles distinct and nearly rectangular as 

 viewed from above. Length 10-12 mm.; width 5.1-6.2 mm. 



This well-known species needs no more extended descrip- 

 tion. The uniformly dense punctuation of the elytra, as well 

 as the occipital smooth space are peculiar to this and the 

 following species. There appear to be no secondary sexual 

 characters aside from the somewhat stouter hind thighs of 

 the female. 



Sordida is most frequently taken in the maritime regions of 

 the North Atlantic States but seems nowhere very abundant. 

 The following States are represented in the material at hand: 

 Maine, New Hampshire, Massachusetts, New Jersey, Maryland, 

 Virginia, North Carolina, Michigan (Marquette). LeConte 

 gives also Pennsylvania and Georgia. 



2. D. rugosioides Schf. 



Almost precisely like sordida, except that the pubescence of the head 

 and prothorax is not longer than that of the elytra, being exceedingly 

 short and grayish in color throughout. 



The type is from Hampton, New Hampshire. Two exam- 

 ples sent me by Mr. Leng labeled "So. Pines, N. C." answer 

 well Schaeffer's description. In one of these there are large 

 discal impunctate areas on the pronotum, which are scarcely 

 at all indicated in the other. The species is not represented 

 in any other of the numerous collections sent me, and notwith- 

 standing its different appearance, it is not unlikely that it will 

 prove to be only a variety or aberration of sordida. 



3. D. mimosas n. sp. 



Variable in color from reddish brown to dark brown or nearly black, 

 entire upper surface clothed rather plentifully with fine erect hairs 

 averaging in length about two-thirds or three-quarters the width of 

 the scutellum; prothorax and elytra minutely alutaceous. Labrum
