dicating the terminatioa of the auxiliary vein, there is a short, distinct, 

 oblique cross- vein nearly in continuation of the base of the costa, but 

 bent slightly downward, which reaches the first longitudinal vein ; the 

 latter runs close to the costa and strikes it about midway between the 

 tip of the auxiliary vein and the tip of the wing; the costa apparently 

 runs exactly to the tip of the second longitudinal vein ; the third and 

 fourth longitudinal veins run parallel to each other to a very little way 

 beyond the extremity of the auxiliary vein, where they are united by a 

 short cross-vein, beyond which they both diverge from each other in 

 opposing curves, equally turned aside from their former course; the 

 third longitudinal vein runs to the tip of the wing; the fourth is united 

 half-way to the border of the wing by a long oblique cross-vein, run- 

 ning at right angles to the fifth longitudinal vein. The extremity of the 

 basal cells apparently lies about half-way from the base of the wing to 

 the tip of the auxiliary vein, but this point is very obscure. Length of 

 wing 1.65"'»i; breadth of same 0.95'""-; length of thorax O-TS"""'; breadth 

 of same 0.55"""'. Chagrin Valley.
