344 THE CANADIAN ENTOMOLOGIST 



largely behind (but not apically), piceous; clypeus produced, but 

 ordinary; sides of face with dense, appressed, very pale yellowish 

 hair; front dull and granular; antennae long, the scape and two 

 following joints yellow, the others pale ferruginous, the flagellum 

 more or less dusky above, especially at base; fourth antennal joint 

 about as long as second and third together; mesothorax and scutel- 

 lum densely punctured but shining, with thin, rather long, pale 

 hair; basal area of metathorax covered with coarse, vermiform 

 rugae; tegulae pale, with a yellow spot; wings hyaline, stigma pale 

 ferruginous, nervures testaceous; first recurrent nervure joining 

 second submarginal cell beyond the middle; hind legs not modi- 

 fied; abdomen closely punctured but shining, with thin hair, but 

 no bands; apical segment pale reddish, emarginate; venter mainly 

 yellow, hind margin of fourth segment broadly W-like,' the margins 

 of the notch ferruginous. 



Chile (E. C. Reed), U. S. Nat. Museum. Closely related to 

 A. citricarnis {Halictus citricarnis Vachal), but that species dif- 

 fers by the somewhat greater size, the presence of yellow depressed 

 hair on abdomen, the granular area of metathorax, the yellow 

 antennae, and the slightly emarginate fourth ventral segment. 

 Also related to A. paulista {Pseudagapostemon paidista Schrott.), 

 but differs in being smaller, with yellow mandibles. It has the 

 clypeus yellow with two dots, as in ^. paulista, not as in .4. nasua 

 {Pseudagapostemon nasua Schrott.). It does not seem advisable 

 to regard Pseudagapostemon as more than a subgenus.
