 rior tip ; thighs yellow, black at tip and base ; tibiae black, 

 yellow within and at tip, on the posterior tip a very short, 

 'acute spine ; tarsi much dilated and deeply ciliated be- 

 hind, yellow-white, covered in their greatest part by a 

 yellow broad scale, which is honey -yellow at tip ; nails 

 honey-yellow : intermediate tarsi cordate, the lobes of

Mr. Barabino sent me this species. It differs in many 

 respects from the M. latimanus^ Nob. (Western Quarterly 

 Reporter) w^hich has in that species the anterior coxas 

 black ; the appendage of the anterior tarsi shorter, &;c. but 

 it is perfectly congeneric with it, as well as with Antho- 

 PHORA Jagopoda, Fabr., if I may judge by the similarity 

 of the anterior feet, though it certainly approaches Steles 

 in the paucity of ventral hair. The maxillary palpi of 

 latimanusj have the second joint rather longer than the 



first- ' . 



M. brevis. Black; not remarkably hairy; anterior 



tarsi simple ; abdomen short. ' 



Inhab. Indiana. 



^ Body black, somewhat polished : head densely 

 covered with long, yellow^ish hairs in front : thorax with 

 whitish hair, sometimes tinged with yellowish, and not 

 concealing the surface : wings a little fiiliginous, tinged 

 with violaceous : venter not, or hardly longer than broad : 



M 



tergum with small, dense punctures, and a narrow, white 

 band on each segment ; anal segment transversely con- 

 cave, at its tip emarginate, in the middle and on each side,
