and relatively inconspicuous; Sc^ is almost opposite the fork 

 of ^2+3 J cell 1st M^ broader and the basal deflection of 

 M^-\-„ consequently longer; basal deflection of Cu^ some dis- 

 tance beyond the fork of M as in C. nipponensis. In both 

 C. autumna and C. japonicck, the second anal vein adds between 

 one-fourth and one-half the length of the long sector.

A NOTE ON AEDES NIPHADOPSIS DYAR & KNAB 



(Diptera, Culicidce) 

 By HARRISON G. DYAR 



This species was described (Ins. Ins. Mens., v, 166, 1918) 

 from specimens taken in Salt Lake County, Utah, by Prof. 

 C. T. Vorhies, only the female being made known. Through 

 information kindly supplied by Prof. Vorhies, I was enabled 

 to locate the breeding places of the species. The larvae oc- 

 curred most numerously in a railroad ditch-pool full of short 

 stems of last season's grass near the hot springs to the north- 

 west of Salt Lake City. The water in the pool was salt and 

 bitter from minerals in the spring.
