and the organ there alluded to is probably the mobile efferent duct 

 bent downward from the protecting corneous sheath.

Moderately stout, highly polished, black, the bases of the pro- 

 thorax and elytra feebly rufescent ; sterna and antennae toward 

 base, rufo-testaceous ; legs blackish, the tarsi and base of the 

 femora testaceous. Head subim punctate, rather longer than 

 wide, semi-circularly rounded behind the eyes, which are moderate 

 in size and rather prominent ; occiput with afoveiform impression 

 at the middle of the base ; antenna^ long, distinctly and gradually 

 incrassate, the tenth joint slightly' longer than wide, the third and 

 fourth elongate and subequal. Prothorax much longer than wide, 

 distinctly narrower than the head, globularl}' convex before the con- 

 striction and expanded toward base,the punctures minute and very 

 remote, except in the middle toward base,where they become larger,, 

 dense and distinct. Elytra almost twice as long as wide, feebly 

 dilated behind, about two and one-half times as long as the pro- 

 thorax, the scutellar impression deep, the omoplates prominent ^ 

 disk scarcel}^ visibly impressed near the base, but having a trans- 

 verse and well defined yellow band at basal fourth interrupted 

 at the suture ; punctures coarse and sparse from the base to about 

 the middle, thence gradually ver}' fine and remote to the apex^ 

 the pubescence short, stiff, semi-erect and remote, with erect 

 widely dispersed bristles intermingled. Abdomen shining and 

 sparsely pubescent. Length 3.0-3.5 mm,, width 0.8-1.0 mm. 



Rhode Island to Iowa. The tjq^e above described is a male 

 from the shores of Narragansett Bay, and differs slightly from 

 some of the western specimens in its smaller size, rather narrower 

 head and sparser punctuation. 



The oedeagus of this species is very complex. The genital 

 segment is short and simple, with a rounded shallow sinuation at 

 the middle of the apex subequal in extent and degree of curva- 

 ture to the lateral lobes. The efferent duct is extremely long 

 and slender, lying in the wide deep inferior opening of a long 

 broad sheath, which is. parallel-sided and flattened dorsall}' for 

 the greater part of its length, but narrowed near the apex, 

 where it becomes split into three lobes of equal length, the 

 two lateral hollowed internally and finely setose within at
