long wings with heavilv cilinteil costal margin, the auxiliary vein terminat- 

 ing just before the middle, ami the first longitudinal vein not very far before 



the tip; the other veins of the wing can not be determined. The legs are 

 pretty stout and densely haired. About the fly are scattered many arcuate, 

 tapering, spinous hairs 0. 7""" long, evidently the clothing of the thorax.

A single specimen is preserved showing a dorsal view of the bodv 

 but with no distinct appendages excepting one wing which is imperfectlv 

 figured mi the plate. The thorax is broad oval, and the abdomen oval, as 

 long as the head and thorax together, narrower than the thorax, tapering 

 from in front of the middle backward, and rounded at the tip. The wing 

 is as long as the thorax and abdomen together. The third longitudinal 

 vein terminates at the tip of the wing, the first in the middle of the outer 

 half of the wing, and the second midway between them; the basal cells 

 are about one-third the length of the wing (indicated in the plate by the 

 jingle in the fifth longitudinal vein), and the oblique posterior transverse 

 vein is situated at its upper extremity, about midway between the middle 

 IKISJI! cell ;iml the apex of the wing. The exact length of the lower basjil 

 cell cMii not lie determined.
