hioma^ and, besides this, the two differ radically in the form 

 of the abdomen, there being only two basally impressed ter- 

 gites here, instead of the three of that genus and Rheochara. 

 The general surface of the abdomen is perfectly smooth and 

 highly polished, without trace of minute ground sculpture of 

 any kind. The single known species may be identified by the 

 following characters: — 



Moderately stout, convex, subparallel, strongly shining, piceous-black, the 

 elytra pale rufo-testaceous, clouded with blackish at the sides in the 

 vicinity of the apical angles; antennae blackish, the basal joint and legs 

 throughout pale testaceous; vestiture fine, subdecumbent and some- 

 what inconspicuous ; head nearly as long as wide, about three -fifths 

 as wide as the prothorax, extremely minutely, sparsely punctulate; an- 

 tennae fully as long as the head and prothorax, gradually and strongly 

 incrassate distally, slender basally, the subapical joints about two- 

 thirds wider than long, the second and third elongate and equal, the 

 fourth normal, much shorter and narrower than the fifth; prothorax 

 about a fifth wider than long, parallel, the sides broadly and evenly 

 arcuate, the base similarly arcuate, the punctures very fine, rather 

 sparse and indistinct; elytra somewhat transverse, evidently though 

 not very greatly wider and longer than the prothorax, the suture equal 

 in length to the median line, the punctures fine but distinct, rather 

 close-set; abdomen at base almost as wide as the elytra, gradually nar- 

 rowing in apical half, parallel toward base, the punctures very fine but 

 distinct, evenly distributed throughout each tergite though becoming 

 sparser in the two basal impre8Sions,|ratber close-set toward the abdo- 

 minal base but becoming excessively sparse toward tip. Length 2.8 

 mm.; width 0.8 mm. California (Pasadena) fenyesl Bernh. 



I owe a representative of this very interesting species to 

 Dr. A. Fenyes, of Pasadena, in honor of whom it was recently 

 named by Mr. Bernhauer, (D. Ent. Zeit., 1905, p. 249). 



A number of European Aleocharae have been noted from 

 time to time as occurring in America, besides fuscipes and 

 nitida before mentioned ; among these are Xenochara puherula^ 

 which has doubtless been confounded with our bipartita, 

 moerens Gyll., and morion Grav., the last being a very isolated 

 minute and peculiarly sculptured species with very broad 

 mesosternal process. Graciliformis Fauv., of the Henshaw 

 list of 1895, is unknown to me; it is probably a manuscript 

 name.
