genus; in a single specimen which I take to be the female, the 

 thorax is decidedly longer and less transverse and the proster- 

 num is broader but in every other respect the specimen agrees 

 although the antennae are as usual shorter than in the male. 

 Altogether seven specimens of this species are before me in regard 

 to two others which agree in everything except that the elytra 

 are smooth and shining, I can come to no conclusion, either the 

 rugosities are abnormal, which is not likely to be the case in so 

 many specimens, or those which have smooth elytra represent 

 another species but these latter are absolutely indistinguishable 

 from the others in every other respect. 



21. Suti-ea marg-i ni penili s, sp. n. 



Flavous, head and thorax impunctate, elytra black, shining, 

 nearly impunctate, with rather broadly reHexed lateral margins, 

 the base with a transverse depression. 



Length 4 millim. 



Of more elongate and parallel shape than the preceding spe- 

 cies, the head broader and shorter, the eyes larger, frontal tu- 

 bercles strongly developed, labrum piceous, antennae very slen- 

 der, extending to the middle of the elytra, fulvous, the apical 

 two or three joints darker, thorax scarcely twice as broad as 

 long, the lateral margins rather strongly rounded, anterior an- 

 gles distinctly oblique, the surface transversely convex, impunc- 

 tate, the sides narrowly margined, flavous, scutellum black, 

 broad, elytra with a distinct transverse, basal depression, extre- 

 mely minutely punctured in obsolete widely separated rows, 

 black, shining, the sides with a distinct, rather wide, reflexed 

 margin and an obsolete costa from the shoulders to the apex, 

 the latter somewhat produced ; abdomen and the posterior fe- 

 mora black, rest of the under side and legs flavous, metatarsus 

 of the posterior legs longer than the following joints together.

There will not be much difficulty in distinguishing this spe- 

 cies on account of the broad elytral margins and the produced
