posterior cells. It differs from anthrax in its long lateral facial pile 

 and in the lack of a black macula at the base of the last abdominal 

 segment. It is easily separated from abscondita and unicolor.

On page 102, Vol. XXVII of the Canadian Entomologist, Prof. 

 Townsend has compared his specimen of ornatipes with drawings of an 

 insect from Brookings, S. D., sent him by Prof. Aldrich, and con- 

 cludes that the two are of distinct species. On comparison of Prof. 

 Aldrich's typical specimen, which he has lately sent me, with the type 

 of ornatipes, I' must confess I can see no specific differences. It 

 should be remembered that Prof. Townsend had only a drawing upon 

 which to base his opinion. The membranous appendage of the 

 third tarsal joint is on the same side of the leg in both specimens; 

 and in both the posterior branch of the fourth longitudinal vein falls 

 short of the border of the wing. In the type specimen the margin of 

 both wings strangely enough was folded over near the tip of the wing 

 which apparently brought the posterior branch of the fourth vein 

 out to the very margin. The other differences mentioned are unim- 

 portant. 



There now have been three specimens of this species recorded 

 from the widely separated localities Illinois (Prof. Forbes, No. 

 15,979), Brookings, S. D. (Aldrich, on a window i)ane), and 

 Ithaca, N. Y. (Nathan Banks). 



In Paper I an enumeration was attempted of the species of this 

 family. A recently described species, Callomyia atirantiaea Bezzi, 

 taken in the Alps, was omitted. Dr. Bezzi says* that this species is 

 unlike all other known members of the genus in the bright color of 

 the male, previously known males being entirely black. It is inter- 

 esting to note that in Calloniyia venusta Snow (1. c.) we have another 

 species in which the males show the bright colors of the females. 

 Venusta is easily distinguished from atirantiaea by its black thorax 

 and antenuLTi. 



Yet four other species, C. humeralis Lw., P. reetinervis v.d.Wulp, 

 P. sitperba Kowarz and P. barhata Kowarz, all from Europe, 

 should be added to the list, making in all si.xty species of this family 

 now known, so far as I can ascertain.
