pleurce to designate the lower beaded margin of the epipleurse, which, although 

 generally small and sometimes obsolete, occasionally becomes larger and rather 

 conspicuously modified. It is hoped that this will tend to promote conciseness, 

 and that the consequent reduction of words will warrant the proposed nomen- 

 clature. 



CARABID^. 



PSEVDOmORPHA Kirby. 



By referring to the table of species published by Dr. Horn (Trans. 

 Am. Ent. Soc, X, p. 273), it will be seen that the following form is 

 not closely allied to any hitherto known. It is extremely slender, 

 parallel and convex, and is distinguished by the nine series of ely- 

 tral punctures being very distinctly traceable. 



P, cylilldrica, n. sp. — Parallel, very convex, rather more than three 

 times as long as wide, uniformly blackish-piceous above ; under surface and 

 legs bright rufous ; integuments highly polished ; margins fimbriate. Head 

 short and broad, feebly convex, nearly four-fifths as wide as tlie prothorax, 

 very finely, sparsely and unevenly punctate, the punctures in the form of 

 minute strongly embossed rings ; eyes large, finely faceted ; antennje slender, 

 compressed, cylindrical ; joints four to eleven very compactly joined, second 

 thre(^-fifths as long as the third, tlie latter longer than the fourth, five to ten 

 subequal, nearly as long as the third, the eleventh longer. Prothorax scarcely 

 more than one-third wider than long ; sides very feebly convei-gent from base 

 to apex and just visibly arcuate; basal angles — viewed laterally — broadly 

 rounded, ajiical narrowly rounded ; base and apex transversely truncate, tlie 

 former with a fringe of short pointed closely placed seta? ; disk transversely, 

 very strongly convex, very narrowly explanate along the sides, margined at 

 the sides and apex with a wide elevated bead which is completely obsolete 

 throughout the basal margin, very minutely, sparsely punctate ; ^lunctures 

 ratlier unevenly distributed, annulate ; median impressed line completely 

 obsolete. Scutellum very minute, transversely triangular. Elytra fully as 

 wide as the base of the prothorax, twice as long as wide, three and two-tliirds 

 times as long as the prothorax ; sides parallel and straight ; together abruptly 

 subtruncate at apex, the truncation broadly arcuate ; disk cylindrically and 

 strongly convex, with nine distinct and almost even series of fine distant sub- 

 asperate punctures, the punctures of the second series from the suture much 

 larger and with longer setre, those of the fourth series also more distinct but 

 much smaller than those of tlie second ; intervals impunctate. Length 7.0 min. ; 

 width (base of prothorax) 2.1 mm. 



Texas (El Paso). Mr. G. W. Dunn. 



The single specimen is a male, and the sexual characters are 

 remarkably distinct. The third and fourth segments of the abdomen 

 have, each, a large transversely-elliptical impression, or more appa-
