thighs with two very minute, equal, well separated denticles ; hind 

 tibia not visibly carinate externally, the terminal spur about two-fifths 

 the length of the first tarsal joint. Length, 1.1-1.15 mm. ; width, 

 .7-. 8 mm. 



Hyannis (Cape Cod), Mass.; Newark, New Jersey. The 

 type is one of a considerable series taken by Mr. Frederick 

 Blanchard at the first named locality. 



The smallest species known to me, though closely ap- 

 proached in size by seminulum, which is nearly related and 

 much resembles it. The latter may, however, be at once 

 distinguished by the much shorter spur of the hind tibia, 

 and the obvious coarser punctures of the pronotum ; the 

 form is also slightly more elongate, and the pubescence is 

 is not quite so distinctly marmorate. In his description of 

 seminulum Horn alludes to the presence of a series of distant 

 coarse punctures on the elytral interspaces, This appear- 

 ance is due chiefly, if not entirely, to interruptions in the 

 pubescence, there being scarcely a trace of any such punc- 

 tures when the surface is denuded. 



OTIORHYNCHID^E. 

 EUPAGODERES Horn. 



So far as our species are concerned, the members of this 

 genus are at once separable from those of Ophryastes by the 

 prothorax being narrower and devoid of tuberosities at the 

 sides. Dr. Sharp rejects this character as unreliable or in- 

 sufficient, but remarks that they may be satisfactorily sepa- 

 rated by the presence {Eupagoderes) or absence {Ophryastes) 

 of adhesive pubescence from the lobes of the third tarsal 

 joint. I have, however, already pointed out* that this char- 

 acter is largely, if not entirely, a sexual one, common to 

 species of both genera. In this connection it is a significant 

 fact that wickhami described by Sharp as an Ophryastes is really 

 a Eupagoderes. The tarsi in Ophryastes are, it is true, gener- 

 ally if not always narrower than in Eupagoderes, sex for sex ; 

 but the degree of dilatation is variable in both genera, and 

 judged by this character alone, many females of Eupagoderes 

 would easily pass for Ophryastes. Notwithstanding this fact
