with rather hnrge, very numerous punctures, more dense and con- 

 fluent on the sides ; lateral edge a little obtusely dilated at the 

 middle : elytra with numerous punctures, and with two double 

 striae of punctures on the disk, one or two on the exterior sub- 

 margin, and a single subsutural one : beneath glabrous : nails with 

 a remarkably robust broad compressed truncated tooth. 



Length three tenths of an inch. 



Although this species is very similar in some respect to the 

 mocsta, yet it is so much smaller as to [199] be readily distin- 

 guished ; the clypeus also of that species is emarginated, and the 

 punctured scries are much more regular than those of the present 

 species, in which the punctures of the series are often confluent 

 with the punctures of the interstitial lines. As regards, size, it is 

 but iittle smaller than vesjjeriina, which has numerous indented 

 striae on the elytra. 



[Also a Dqilotaxis and appears to be D. testacea Burm. — Lec] 



G. M. UNIFASCIATA. — Thorax very dark green ; elytra testa- 

 ceous, with a black abbreviated band or spot on the middle. 



Head densely punctured, particularly before, very dark green- 

 ish on the vei'tex, and tinged with cupreous before : clypeus en- 

 tire at tip, the edge reflected : thorax blackish-green, rather 

 sparsely jmnctured, punctures small, lateral edge a little dilated 

 rather before the middle : scutel dark green, sometimes tinged 

 with cupreous, with a few punctures : elytra pale testaceous, in a 

 particular light having a slight metallic tinge, each with seven 

 or eight regular striae of punctures, and a few scattered ones 

 near the suture ; margin and suture dusky ; on the middle is a 

 blackish band which is more or less interrupted or undulated : 

 beneath black, slightly tinged with green and cupreous : stethi- 

 dium a little hairy : acetabulum with an indented longitudinal 

 line : nails, of the anterior and intermediate feet having one nail 

 simple, and the other bifid at tip, of the posterior feet simple. 



Length two-fifths of an inch. 



Var. a. Klytra, excepting at base, simple. 



This species is very closely allied to vanaiis Fabr., but it may 

 be distingui.shcd by its much larger size. [200] The rariiuis 

 is not uncommon in J'eiinsylvania, but the present is a Southern 

 species. Dr. J. F. Mclsheimer gave it the name of vrrmi/is,
