CLASSIFICATION OP THE BEES. 63 



received by the second cubital cell beyond the middle; mandibles at 

 apex bluntly rounded, edentate: maxillary palpi 3-jointed. 



Epimelissodes Ashm. n. g. (Type M. atripes Cr.). 



First and third cubital cells, along the cubitus, subequal, the second smaller 



or shorter than either the first or third, the third the longest. 



First recurrent nervure received by the second cubital cell at or near its 



middle or beyond the middle, the second recurrent received by the 



third cubital cell near its apex or almost interstitial with it; third 



transverse cubitus not strongly angulately bent, the knee formed by 



the curvature of the vein towards the radius rounded. 



Maxillary palpi 6-jointed ; submedian and median cells equal ; abdomen 



in 9 black, not fasciate Syiiliulon i;i Patton. 



Maxillary palpi 5-jointed ; submedian cell a little shorter than the median. 



Xenogloss Smith. 

 Maxillary palpi 4-jointed ; abdomen fasciate or subfasciate (rarely with- 

 out) IVIelissodes Latr. 



First recurrent nervure received by the second cubital cell much beyond its 

 middle or its apex, the second recurrent received by the third cubital 

 cell just in front of the third transverse cubitus (only interstitial) ; 

 third transverse cubitus strongly angulated or bent, its upper half or 

 more bent inwardly towards the radius, so that the third cubital cell 

 along the radius is only one-half as long (or even less) than along the 

 cubitus: first discoidal cell not longer than the marginal cell, most 

 frequently somewhat shorter. 

 Maxillary palpi 6-jointed; abdomen in 'J, not fasciate, in 9 fasciate: sub- 

 median cell a little shorter than the median. 



Eiisynlialoiiia Ashm. n. g. (Type 8. Edwardsii Cr.). 

 Maxillary palpi 5-jointed, the last two joints united, scarcely longer than the 

 third, first and second joints subequal, much longer than the third ; 

 submedian cell very distinctly shorter than the median ; second cubi- 

 tal cell quadrangular, longer than wide, but shorter than the first or 

 third ; abdomen fasciate, or iu 9 clothed with a fine, short, whitish 

 or pruinose pubescence. 



Xenoglossodes Ashm. n. g. (Type X. albata Cr.). 

 Maxillary palpi 4-jointed : scopa on hind legs iu 9 long niid densely plu- 

 mose ; antennae in £ longer than the thorax, the clypeus yellow 

 (rarely black). 

 Maxillary palpi with all the joints slender, the second and third elongate, 

 the first and fourth very short; abdomen fasciate. Mel issodes Latr. 

 Maxillary palpi with the first joint enlarged, thickened, nearly as long as 

 2-4 united, the following slenderer, the second about as long as 3-4 

 united Eeplectica Holmberg. 



19. First and third cubital cells, along the cubitus, about of an equal length or 



nearly, the second much smaller, wider (higher) than long; transverse 

 median nervure interstitial or nearly, at most uniting with the median 

 veinjustin front of the basal nervure; maxillary palpi 6-jointed. .21. 



20. First and second cubital cells subequal, the second a little the longer; basal 



depression on first abdominal segment bounded superiorly by a dis- 

 tinct transverse carina; hind tibiae in 9 with a dense scopa : antennse 

 in % very long, much longer than in 9, the clypeus yellow, maxillary 

 palpi 5-joiuted Eucera Scopoli = Anthophorvla Ckll.
