Ephistemus Stcph. 

 In this genus, as in the preceding, the body is evenly oval and 

 rather pointed behind, the sides of the elytra and prothorax being 

 perfectly continuous and without a reentrant angle at the contiguous 

 bases. The surface is virtually glabrous, having only a few extremely 

 minute hairs visible under high amplification, and is feebly and 

 sparsely sculptured. r)ur single representative is the following : — 



Oval, convex, polished, black or piceous-black the elytra gradually rufo-testaceous 

 posteriorly almost in apical half, the legs and antennae paler ; surface impunctate ; 

 prothorax moderately transverse, the sides convergent and rather strongly, almost 

 evenly arcuate ; elytra rather less than three times as long as the prothorax and 

 about a third to nearly half wider, widest at two-fifths, the sides strongly, almost 

 evenly arcuate, converging behind, the tip narrowly rounded. Length 1. 1 mm. ; 

 width 0.72 mm. New ^'ork. New Jersey, Pennsylvania and Indiana. 



apical is Lee. 



Almost i)erfectly resembles the European i/i/iiidiafiis, but rather 

 stouter and much larger ; the latter species seems to be distinct from 

 glolnilits, with which it is united as a variety in the European catalogue 

 of Heyden, Reitter and Weise.-'^

 It matters but little what name is used to designate a genus, and 

 consequently perhaps, a family, provided it be the oldest properly 

 published name, and that there be unanimity of opinion in regard to 

 the points at issue. The Geoffroyian name Trifoi/m has been adopted 

 in the most complete European catalogue, presumably after proper 

 investigation, for the familiar Afyccfopliagus, and, as arbitrary dissent 

 from this decision would only tend to perpetuate ambiguity in the 

 fundaments of nomenclature, I am ready to take any course which 



* The following is a new species from the European fauna, recently received from 

 Mr, Reitter : 



Narrowly oval, polished, blackish throughout, the elytra obscurely rufescent,blackish toward base, the 

 legs and antennae pale, extremely minutely, feebly and sparsely punctate; prothorax rather short and 

 strongly transverse, the sides converging and arcuate as usual ; elytra relatively long, rather more 

 than three times as long as the.prothorax but only about a fourth to a third wider, subinflated be- 

 tween a third and two-fifths from the base and narrowly rounded at tip. Length 0.95 mm. : 

 width 0.6 mm. Russia (Caucasus) reitteri, sp. no v. 



Distinguishable at once horn globulus or dimidiatus by its narrower and less ovate 

 form, the elytra in the species referred to being from two-fifths to a half wider than 

 the prothorax.
