Remarks. 



1. G. nigrella Lee. — ''Tachyusa nigrella. Elongate, black, shining, 

 with delicate ashy pubescence, very finely punctulate : thorax obsoletely 

 canaliculate, before the base transversely slightly foveate, a little shorter 

 than broad ; abdomen in front slightly narrowed ; segments 1-3 trans- 

 versely deeply impressed; legs blackish-pitchy. Length, .12. Middle 

 and Western States ; common." 



There is in the Leconte collection at Cambridge, Mass., a specimen 

 labelled Jiigrella, and there is a pink disk on the pin under the specimen ; 

 the pink disk meaning : Middle States (Ohio, Penna., West N. Y.). Below 

 the above specimen, without any name, but probably referred by Leconte 

 to nigrella^ is another specimen with a pink aiid yellow disk, the latter 

 disk meaning : Western States (N.-W. Va., Ky., N.-W. Tenn., S. 111.), 

 and, finally, there is another row with three specimens, all with pink disks. 



This species is well characterized amongst the eastern nearctic 

 Gnypetas by the prothorax being simply foveate at base in the female and 

 lacking the geminate punctures ; the impression becomes longer in the 

 male, but is not traceable beyond the basal half of the prothorax. It is 

 the most common eastern species in our fauna, not closely related to any 

 other from the northern hemisphere ; it is known to me from the following 

 localities : Penna. (Pittsburg) ; Mass. (Chicopee, Framingham) ; N. Y. 

 and Md. (Baltimore). 



2. bait if era Lee. — ''Tachyusa bait if era. Less elongate, blackish- 

 pitchy, shining, finely punctulate, with delicate pubescence ; thorax, elytra
