THE CANADIAN ENTOMOLOGIST. 343 



(8) Megachilma : Andronicus, Alcidamea, Osmia, Heriades, Megachile, 



Coelioxys, Anthidium, Stelis. 



(9) Ceratinince : Ceratina. 



(10) Melissodincg : Synhalonia, Xenoglossa, Melissodes, Entechnia, 



Emphor. 



(11) Xylocopince : Xylocopa. 



(12) AntJiophorince : Anthophora, Clisodon, Habropoda, Bombomelecta, 



Melecta, Epeolus, Neopasites. 

 {iT^) Bomb ince : Bombus, Psithyrus. 

 (14) Apimc : Apis. 



It seems to me that Mr. Ashmead's classification is an improvement 

 on that of Delia Torre : in placing Sphecodes near Halictus ; in separating 

 Colleifs from Prosopis, as far as he goes ; in giving a lower position to 

 Megachilidas, which the long first submarginal cell clearly supports, and in 

 separating Ceratina from Xylocopa. 



In placing CoUetes with Andreninae I mean to emphasize the impor- 

 tance of the venation, facial foveas and pollen-apparatus against the form 

 of the tongue. 



At present I do not accept Pseudopamirgus as a synonym of Panur- 

 ^^inus. I refer to it Scrapier a?idrenoides ^m., Calliopsis albitarsis Cr., 

 asteris, labrosus, rudbeckice, parvus., compositarinn, soiidagi/iis, rugosus, 

 and Pamirginus labrosiformis. 



The genera Mr. Ashmead refers to Panurgidre, I would arrange in 

 the following way, excepting those of which I have not seen 

 examples : — Andre?ii/ue : Andrena ( = Biareolina, Parandrena); Balictince : 

 Halictus (incl. Dufourea Ashm. , Hemihalictus CkW.) ; //a/hfo/d/'/ue: Du- 

 fourea, Halictoides, Rhophiloides, Rhophites; Melittincp.: Macropis ; Dasy- 

 podince : Dasypoda ; Panurg'uice : Panurgus, Panurginus ( = Scrapteroides), 

 Pseudopanurgus, Epimethea, Camptopocum, Calliopsis ; Perditince : 

 Perdita, etc. 



CORRIGENDA. 



Page 8, first line of description of Psilopa petrolei, erase the comma after 



the word " coloured.' 

 Page 100, lines 15 and 9 from bottom ; page iii, line 6 from top; and
