Since the note on the genus ZeugopJiora was printed (on p. 73 of the 

 previous volume) two other species have been received from Mr. R. J. 

 Crew, of Toronto : Z Kirbyi, Baly {Reifieckei, Grote), which is uniformly 

 yellowish above, and Z. sciitellaris, Suffr., in which the head and thorax are 

 entirely yellow, while the elytra are black, with large punctures, separated 

 by more than their own diameters. Collectors should be on the lookout 

 for Z. consa?igui?iea, Cr., which differs from scutellaris in having the 

 occiput black, while the elytral punctures are close. It is known to me 

 from Wisconsin, Illinois, and Manitoba. 



Attention should be called to a clerical error in the table of Chry- 

 somela. The name labyrinthica should read pnirsa. Dr. Leconte is 

 said to have distributed it under the manuscript name of labyrinthica, 

 and in thinking of it by this characteristic cognomen the error was 

 committed. 



ON THE MEXICAN BEES OF THE GENUS AUGOCHLORA. 



BV CHARLES ROBERTSON, CARLINVILLE, ILLINOIS. 



In the Transactions of the American Entomological Society, 

 XX., 147, after notes and descriptions of five species of Augochlora, I 

 gave the following note : " All of the species of AugocJilora mentioned 

 above agree in having the hind spur serrate with numerous fine teeth, and 

 form a distinct section of the genus. Another section, to which belong 

 A. hicidtila, Sm., A. sumptuosa, Sm., and A. kumcra/is, Pttn., is charac- 

 terized by having this spur provided with four or five long teeth." 



In the January number of this journal, XXIX., 4-6, Prof. Cockerell 

 makes use of these distinctions — under more obscure terms, however — 

 and has given special names to these sections, and that, too, without 

 referring to my note. I have no objections to his giving names to the 

 sections, however, for I have had ample opportunity to do so, if I had
