throughout. The collar is contrastingly pale, whitish, black lined. It is 

 not the species figured by Holland as badistriga, to which my third speci- 

 men referred to in my original notes probably belongs, and to which I 

 shall refer under the additions. The species of this group appear to be 

 much missed in eastern collections, and as they do not seem common, I 

 am somewhat at sea as to the variation. 



185. Oncomemis poliachroa Hamps. (Cat. VI, 175, 1906). — Sir 

 George Hampson has thus described the species I had listed as chandleri^ 

 and all previous records of chandleri from the Northwest and from B. C. 

 that I have been able to verify refer to his species, of which the type is 

 from Calgary, and which is the chandleri of Holland's Moth Book. As it 

 happens, I have a specimen of true chandleri from High River, which I 

 have compared with the type, and which will be referred to later.

The following crane-fiies are believed to be new to science : ' 



Adelphomyia tninuta, sp. nov.

Subcosta quite long, extending almost to the anterior margin of cell 

 R3; SC;, far distant from the tip of Scj, so that Sc^ is four times the length 

 of Sca- Radius long, cross-vein r far back from tip, about four times its 

 length and near to the anterior end of cell Rg. J^s moderately long, 

 arcuated at origin, about equal to R3; R^,3 from one to one and one-half 

 the length of the basal deflection of Cui ; basal deflection of R4+5 about
