rather uniform pale yellowish brown, with very faint traces of common 

 mesial band. 



This species can be recognized at a glance from tiatatrix by the 

 strongly dentate t, a. line, from Parora Texana, with which it has been 

 confused, by the character of t. p. line and reniform. In segura the t. 

 \). line is even as in fiatairix, not crenulate and wavy as in Texana. 



Types, Babaquivera Mts., Ariz., July. 



Eudela heiveta, n. sp. — Expanse i8 mm. 



Head, thorax and wings yellow as in /nendica. Fore wing with 

 broad, semi-transparent fascia, almost reaching costa before apex and 

 inner margin before inner angle. The margins are quite even. A large 

 semi-transparent patch in base of cell, with another about twice as large 

 below it, only separated by vein. Hind wing with broad semi-transparent 

 fascia occupying about one-third of the wing. Under surface as above. 



Types, two A , Kerrville, Texas. 



RECORDS OF DIPTERA FROM LAKE TEMAGAMI, ONT. 



BY JAMES S. HINE, COLUMBUS, OHIO. 



Mr. Frank B. Shuler, of Hamilton, Ohio, while with a camping party 

 on Lake Temagami, Ontario, during the past summer, collected a number 

 of species of Diptera, some of which are worthy of note as matters of 

 record. 



Of most interest is the discovery of a second species of the genus 

 Mesembrma for North America. It agrees so well with the European 

 M. mystacea that I have given it that name. 



The nearctic species of this genus have not received much considera- 

 tion, but Hough has given a short account of the results of his studies in 

 Vol. I of the Biological Bulletin. He is of the opinion that we have 

 only a single species of the genus, and this he determines as M. Latreillei^ 

 of which he makes resplendens a synonym. 



The specimen I have called mystacea is larger than Laireillei, fully 

 15 millimefcres in length and quite robust, the thorax is clothed above 

 with golden-yellow pile, and so are the last two segments of the abdomen, 

 but on the latter the colour is lighter than on the former. The apical cell 

 of the wing is not so widely open, and the sides of the face are yellow in- 

 stead of silvery. Some of the older authors placed ynystacea in tiie 

 Syrphidae, and I must confess the specimen before me looks very much
