In concluding I wish to extend thanks to Mr. H. C. Fall, 

 who examined for me the types of morsus Lee. and hclcnae 

 Mann; also to Dr. E. C. Van Dyke, who kindly loaned me all 

 of his material in this genus. I am also indebted to Mr. 

 Henry Dietrich for the loan of his material, including three 

 new forms. Prof. H. F. Wickham also sent his specimens 

 which included a number that I had not seen. 



Notes on two Acalyptrate Diptera. 



In 1913 (Jour. X. Y. Ent. Soc. vol. 21. p. 204) Dr. A. L. Melander 

 described M mnctopin iiitcns, distinguishing it from tcniiinalis Low,- '>v 

 its partly black face and parts of the head- This form is ineivly the 

 male of tcnninalis. which has tin- head and its parts yellow or whitish. 



In the same paper he recorded (Vnn^<>;//</ /r;;:r>n;/;'\ MeiLjen from the 

 \vest, an error which I avoided in my paper on the family which ap- 

 peared at the same time. My view has since been o >n firmed by Dr. 

 Aldrich in print. This year I took one specimen of the true fitl-i'ipcs 

 Meigen (femoralis Meigen) at Glen Kcho, Maryland, so that the species 

 really does occur in America though not present in Melander's material 

 from the west. Mendel lias recently followed Melander in recording 

 fcuionilis from this country, the record being based upon the dark form 

 known in Europe as ih'iitici>niis var. nigroscutellata Strohl which is 

 common in the extreme west. J. 1\. M \Moni, Bureau of Biological
