The specimen labelled M. femorata is numbered 872, locality 
unknown, the 9 labelled M. melanophcea is numbered 878

1896: Dalla Torre, Cat. Hym, v. X, p. 436 (M. latimanus, 
Prov. references, cT only). 
One specimen numbered 870, labelled M. latimanus appears 
to be referable to X. femorata Sm. It is from either St. Hya- 
cinth or Cap Rouge as Provancher reports the species from 
both localities. 
I have not added above the reference to the 9 of latimanus 
given by Provancher because I have seen no specimens so 
labelled. 
1888: Add. Fauna Ent. Can. Hym. p. 324, n. 9, 9 (M. 
latimanus). Nothing can be told from the description, which 
appears to be founded on some Xanthosarus. 
Xanthosarus latimanus Say.

Megachile frigida is reported by Provancher from St. Hya- 
cinth and M. mendica from Chicoutimi. A specimen labelled 
M. frigida bears the number 1012 and one labelled M. men- 
dica is numbered 1013.
