taceous; the pectus, the knees and the tips of the tibi.-E are usually fuscous; the 

 tarsi are always testaceous ; the scutellum is occasionally nearly black. The 

 tijis of the mandibles and the antennae are black; the second joint of the latter 

 is half as long as the third.

Massachusetts; Dr. Harris. Found in sandy places in early spring. The 

 ventral segments of one sex (female ?) are furnished in the middle with a broad 

 black velvety patch of hair ; in the other sex this is wanting.

Haldeman, Stansbury's Expedition to Great Salt Lake, 377. 



Two specimens brought from Utah by Capt. Stansbury. For an opportunity 

 of examining them I am indebted to Prof. Haldeman. 



Although so different in form from the preceding, this species exhibits a re- 

 markableparallelism of structure. In the head and thorax there is absolutely 

 no difference to be perceived. The antenna? are shorter and much more attenu- 

 ated externally ; the body being provided with wings, the humeri become pro- 

 minent, while in the preceding apterous species they are obsolete, or very 

 broadly rounded. The larger specimen has a romid patch of black velvety hair 

 on the middle of each ventral segment of the abdomen.

Lake Superior, nat rare. This species varies very much, some of the speci- 

 mens being very dark fuscous; the head and thorax are, however, always varied 

 with testaceous ; the sides of the thorax are slightly sinuous from the prominence 

 of the posteiior angles. 



Although considered by Newman as belonging to the (Edemeridoe, this 

 singular genus seems to me better placed as an anomalous genus of the Cantha- 

 ridjti. The appendaiies between the claws of the tarsi are not found in (Edeme- 

 rid;3e, while in this tribe they have their analogues in Zonitis, Horia and Nemog- 

 natha, th.:ugh in the pre>ent genus they are much larger and obtuse; the 

 mandibles are slervder and acute at the apex, as in the genera just mentioned. 



2. C. v a r i a n s, valde elongatum, utrinque attenuatum, subtiliter punctulatum,

One specimen from iMaiiie, Mr. Brevoort. This species only diffi^rs from 

 the dark colored varieties O'f the preceding by having the posterior ansrles of the 

 t.'.orax less prominent, so that the sides are not sinuate ; the head and thorax are 

 entirely fuscous above, and testaceous beneath.

A larse mass of pentarnerous serricorn C'oleoptera may be distingirished by 

 having the anterior coxa^ inserted in decpacetabula between the pro- and meso- 

 sternum, and the prosternum although sometimes very narrow, entirely cor- 

 oeoas. The abdomen has live visible ventral segments, except in Cebrionidaj,
