Several badly preserved specimens from Sta. Catalina Island agree in sculp- 

 ture, but the sides of the thorax are much more rounded, the legs are nearly- 

 black, and the elytra are less coarsely punctured. If is a little smaller, being 

 1*6 mm. long. It may be named D. catalina?. 



The dilatation of the claws inboth species is broad, and about half as long 

 as the claw. 



ESCHATOCREPIS Lee. 



In this genus the appendages of the claws are as long as the claws, narrow, 

 rounded at tip, and free quite to the base. In this respect it agrees with the 

 European genus Haplocnemis, but differs by the antennae being scarcely 

 serrate, gradually thickened externally, with the fifth joint, as in several spe- 

 cies of Pristoscelis, slightly wider than the contiguous joints. 



The thorax is not wider than long, feebly rounded on the sides from the 

 base nearly to the tip, where they are slightly sinuate, thus rendering the 

 anterior angles somewhat prominent ; the disc is feebly channelled, and 

 marked each side with a deep impressed line extending from the tip to the 

 base.

San Diego, and Fort Tejon, California. The fifth ventral segment of the 

 male is marked with a small rounded impression near the tip. 



MELYRIS Fabr. 

 The only two North American species known to me are of small size, very 

 coarsely punctured, without elevated costse on the elytra.

Additions to the COLEOPTEEOUS FAUNA of the United States. No. 1. 

 BY JOHN L. LECONTE, M. D. 



It is my intention, from time to time, to publish descriptions of the new spe- 

 cies which have been obtained too late for insertion in the " List of the Coleop- 

 tera of North America," and the "New Species of North American Coleoptera," 

 in course of publication by the Smithsonian Institution. As the parts of those 

 two works now in print treat of the same families as are contained in Part I. 

 of the " Classification of the Coleoptera of North America," published by 

 the Institution, the papers of this series will be confined within the same 

 limits. Any interesting discoveries in the succeeding families, in which the 

 penultimate joint of the tarsi is connate with the last joint, (Tetramera and 

 Trimera of the Latreillean method,) and in the Rhynchophora, will be de- 

 ferred, or made known only in faunal memoirs. 



The descriptions of individual members of genera and families are in the 



1866.]
