species without very minute examination. In E. compactulus 

 tiie fourth joint of the maxillary palpus is only about as long 

 as the third, and the sixth is not much longer than the fifth. 

 The first abdominal segment is mucli more coarsely and 

 strongly punctured in compactulus than in Coquilletti, and the 

 third traiisverso-cubital nervure is more bent. 



Mr. Ashmead has referred Anthophorida to Eucera, assum- 

 ing that tiie original specimen, with two submarginal cells, is 

 normal. We cannot accept this conclusion, and as our 

 specimens w ith tiiree submarginals are congeneric with the 

 type of Th'adasieUa, we hold this name to be a synonym of 

 AntJiophorii/a. The raouth-parts of AnthojyJwruhi are, how- 

 ever, practically as in E.vomalopsis, and it seems that the 

 group with a yellow clypeus in the male has at best only sub- 

 generic value. 



Xenoglossodes, Ashm. 



We have before us three species of this genus, separable as 

 follows : — 



(A ) Second joint of maxillary palpus considerably 



longer than lliird ; liftli very minute ; 

 pubescence of abdomen white ; wings very 

 short, nervures fulvous A', albata (Cressonj. 



(B) Second joint of maxillary palpus shorter or 



not longer than the third ; fifth not so 

 minute ; pubescence of abdomen pale 

 ochreous. 



(1) Larger, flagellum of $ black A', imitatrix, sp. n. 



(2) Smaller, flagellum of § orange fulvous 



beneath X. eriocarpi (Ckll.). 



X. eriocarpi was desiCYihed as slu Exoinalopsis, but it belongs 

 here. Mr. Ashmead, without examining the mouth-parts, 

 referred it to Tetraloniella provisionally, since it agreed fairly 

 well with that genus in venation and also in having the 

 clypeus anteriorly margined with yellow. We have no 

 material of Tetraloniella for comparison. 



Our material of A', albata {S ? ) is from Texas {Bel/rage), 

 and was kindly sent by Mr. Ashmead. The description of 

 the new species follows : — 



Xenoglossodes imitatrix^ sp. n. 



? . — Length about 12 millim. 



Just like the male of Entechnia grisella except in the 

 following points : — Face broader, with tlic vertex flattened 

 as viewed in front (in the Entechnia it is rounded) ; sides of
