 Dicranota eucera O. S. and D. noveboracensis Alexander. 



Four specimens taken in Tuckerman's Ravine, and the "Alpine 

 Garden," Mt. Washington, New Hampshire, July 8 and 21, 

 show a remarkable variation of the venation. One is a typical 

 D. noveboracensis, having cell Ml present in both wings (fig. 1). 

 In two specimens this is present in one wing only, which would 

 make the specimen referable to either D. eucera or D. novebora- 

 censis. The other specimen has not only cell Ml, but cell 1st 

 M2 (or discal cell) is also present in both wings. With a large 

 series this might prove a rival to the variable Tricyphona inconstans 

 O.S. 



Apinops atra Coquillett. Fig. 2. 



This is apparently quite a rare Tachinid; only two have been 

 seen by the writer. The first was collected at Southwest Harbor, 

 Mt. Desert, Maine, August 20, 1920, and the second was received 

 from Jos. Ouellet, who collected it at Oka, Prov. Quebec, May 24, 

 1921. The type was from southern Illinois. The specimen from 

 Quebec is especially interesting on account of its abnormal vena- 

 tion, a supernumerary cross-vein being present on each wing in 

 the middle of the first posterior cell. The left wing also has a 

 stump on the second vein just beyond the tip of the first vein. 

 While supernumerary veins are common in the Tipulidae, they 

 are rarely present in the Muscoid Diptera. 



EuGENACEPHALA, gen. nov. 



Eyes oblong, longer than high, cheeks about two-thirds the 

 height of the head; occiput large, facial plate triangular, termi- 

 nating in a point between the base of the antennae with a deep 

 triangular fovea below the base of the antennae. Sternopleural 

 bristles are wanting — while there is a large bristle near the edge 

 of the sternopleura it is distinctly on the hypopleura.
