Length under seven-twentieths of an inch. 



9 Body mucli more robust ; less hairy ; but the bands of the 

 tcrgum are rather wider, sometimes almost interrupted in the 

 middle ; hair of the posterior feet yellowish ; antennae rather 

 short ; nasus black. 



Length nearly two-fifths of an inch. 



A smaller species than ^>r«/«y.sa and much like it; but it may 

 be distinguished by the much longer antenna) of the male, by 

 the nasus being all white, and by the whitish or almost uncolored 

 hair of the head and thorax. 



When recent, the color of the eyes is light blue, with three or 

 four transverse, moveable series of longitudinal dark spots. 



MEGACIIILE Latr. 



M. POLT-irARis. — % Anterior tarsi dilated, deeply ciliated, ap- 

 pendage rather long; spines of the anterior coxae yellow. 



Inhabits Louisiana. 



Body not very hairy, black : wings with a slight fuliginous 

 [407] tint, particularly at tip : tcrgum oblong sub-cjuadrate : 

 anal segment with a sinus in the tip, each side of which are 

 small inequalities of the edge : anterior feet, coxae with promi- 

 nent yellow spines, rufous on the exterior 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 behind, yellow-white, covered in their great- 

 est part by a yellow broad scale, which is honey-yellow at tip ; 

 nails honey-yellow : intermediate tarsi cordate, the lobes of one 

 side more prominent. 



Length eleven-twentieths of an inch. 



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

 from the M. latimanus nob. (Western Quarterly Reporter) which 

 has in that species the anterior coxae black ; the appendage of 

 the anterior tarsi shorter, &c., but it is perfectly congeneric with 

 it, as well as with Anthophora lagopoda Fabr., if I may judge 

 by the similarity of the anterior feet, though it certainly ap- 

 proaches Steles in the paucity of ventral hair. The maxillary 

 palpi of latimanus have the second joint rather longer than the 

 first,
