Two of the species are described from the United States, viz., 

 annulicomis from Illinois and nubilipenuis from the Rocky Mountains in 

 Colorado. Ottawa has furnished two, viz., niger and abdominalis com- 

 municated to Mr. Cresson by the late Mr. Billings, and described in 

 Can. Ent., Vol. L, page 37. Of the former of these, niger, I have taken 

 4 $ and 1 $ , and have found the female ovipositing in decaying maples 

 in June. Provancher also records this species from St. Hyacinthe, Que. 

 The second, abdominalis, I have not succeeded in finding here yet, but 

 I was so fortunate as to take a fine female at Sudbury on the occasion of 

 the visit already mentioned. I have also received this species from Rev. 

 G. W. Taylor, of Victoria, B.C., and his specimen agrees in every particular 

 with that from Sudbury. The species maurus (doubtfully referred to 

 this genus by Cresson) was described from Victoria, and Provancheri 

 was also obtained by Mr. Brodie from Vancouver. The species now 

 described, rufopedibus, is from Montreal, and the remaining species, all 

 described by Provancher, are presumably aiso from the Province of 

 Quebec.
