species without very minute examination. In E. compactulas 

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

 as the tiiird^ and the sixth is not much longer than the fifth. 

 The first abdominal segment is much more coarsely and 

 strongly punctured in compactulas than in Coquilletti, and the 

 third transvers^o-cubital nervure is more bent. 



Mr, Ashmead has referred Anthophorula to Eacera, assum- 

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

 normal. We cannot accept this conclusion, and as our 

 specimens w ith three submarginals are congeneric with the 

 type of Diadasiella, we hold this name to be a synonym of 

 Anthophoi'ula. The mouth-parts of Anthophorula are, how- 

 ever, practically as in Exomalopsis, 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 third ; tifth very minute ; 

 pubescence of abdomen white ; wings very 

 short, nervures fulvous A', albata (Cresson). 



(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. eriocaiyi (Ckll.). 



X. er?ocarpi was described as a.n Exomalopsis, but it belongs 

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

 referred it to Tetrahniella 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 TetralomeUa for comparison. 



Our material of X. albata {^ ? ) is from Texas {Belfrage), 

 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 the vertex flattened 

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