Dear Dr. Aldrich: 



I have studied Bigot s type of 



Anastellorhina bioolor as requested in your letter 

 of 2nd inst., and compared it with the specimen 

 of fleoppllenia villosa received from you. It is 

 certainly not congeneric with villosa and I con 

 sider does not even belong to the same subfamily. 

 In the first place it has only the small first 

 abdominal sternite free and overlapping the terpite, 

 villosa and the Calliphorinae have all the sternites 

 visible, and the Rhiniinae the small first and the 

 larger 2nd sternites free and overlapping the ter- 

 gites. The stem vein is bare and only the radio- 

 cubital node bristly (above and beneath). The head 

 in profile is very much like Surcouf s figure of 

 Amphiboloaia,, indeed I think this may be a synonym 

 of Anastellorhina. Arista plumose to the tip. 

 Ihe eyes, would, in good specimens I believe be 

 found to be microscopically pubescent. Facial ia 

 above vibrissae bare and more acutely bent forward 

 below, than in villosa. Face flatter. No hairs 

 beneath postalar calli and on thoracal squamae. 

 Stout marginal macrochaetae only on last two segments 

 It is not so stout, or M blow-fly like&quot; in appearance 

 as villosa. 



I ihink Johnston and Hardy were probably mis 

 led by Srauer placing Bigot s Hiumpsia dichroiBata 

 and Xanthura in Ana s te 1 1 o rh i naT These two species 

 have notning to do wit a that genus, but are un- * 

 doubtedly congeneric with villosa, in which case 

 Proekon Surcouf sinks as a synonym of jfeopollenia 

 for Suroouf placed these two species after an ex^ 

 amination of the types in his genus Proekon. 



For my part I cannot find any souriSTgeneric 

 distinction between jteopollenia as typified by 

 villosa and our European spe&quot;cTe&quot;s of Calliphora. 



Brauer was quite right in referring So mo my ia 

 rufiventris ( CaJLUphora id Mcq , ) to the genuT&quot; 

 Anastgllorhina, it is certainly congeneric with 

 Tricolor. 



Yours very^ sincerely, 

 /s/ Jas. E. Collin.
