P. rliodura ? runs in mj table of Perdita (Proc. Phil. 

 Acad. 1896) to 71, and is separated from P. 8nowii bj the 

 pallid venter, marldng of clypeus, &c. It most resembles 

 P. crotonis, especiallj in the colour of the abdomen^ but 

 differs at once by the face-markings, granular mesothorax, &c. 

 P. rhodura ^ runs in the table to 12, but is quite distinct 

 from P. chamcesarachcBj to which it comes nearest.

liah. Embudo, Sept. 25. One. 



P. suhfasciata runs in my table of Perdita {I. c.) to 19, but 

 is quite different from P. mentzelioi. It is not unlike P. centi- 

 jrons, but differs at once by the bands on the abdomen &c. 



The only other Perditt taken at Embudo was P. zehrata. 

 Cress., one at flowers of Cleome serrulata, Sept. 26.
