our insect, and was made out from a specimen belonging 

 to the same collection In which he described his dimidid' 

 tusy I have no doubt that it was intended to indicate this 

 species. Dr. Melsheimer was of the same opinion, and 

 has recorded the name in his catalogue. I introduce the 

 description, for the purpose of preserving the Fabrician 



r 



name for a species, not commonly known. 



a - 



MoRDELLA, Latr. 



1. M. hildris. Blackish, silvery-sericeous; elytra 

 with a dilated, irregular, dull yellowish band margined 

 with whitish. 



Inhabits Indiana. 



Body black, somewhat purplish-iridescent, sericeous : 

 head dull yellowish-sericeous : thorax varied with gray 

 hairs : scuiel silvery : elytra with a much dilated, dull 

 golden, sericeous, oblique band, occupying about one 

 third, spread widely towards the scutel, and margined 

 before and behind with a whitish line, the anterior line 

 much angulated and the posterior one reclivate ; tip 

 rbunded : beneath with purple and green reflections, and 

 silvery-sericeous. 



Length about two fifths of an inch. 



This has some resemblance to M. bidentdta, Nob., 

 but it is widely distinct by the elytral band and the much 

 more dilated terminal joint of the maxillary palpi. It is 

 common about the flowers of the Hydrangia cordata, Ph. 

 Its movements are rapid. 



2. M. oculdta. Black ; elytra bifasciate, anterior 

 band with two dots. 



Inhabits Pennsylvania and Indiana - 

 M. fasciata, Melsh. CataL
