could be found. Although search was made throughout the 

 summer in this area, not a single individual was obtained in 

 any other location. Even sweeping failed to bring any to 

 light although other species were obtained in abundance. 



As only perfect specimens were obtained we thought the 

 larvae ought to be easily located in some of the nearby pools, 

 bogs or streams. All these places were searched in vain, 

 though numerous larvae of other species were found. Dyar 

 believes this species lays its eggs singly during the summer 

 and they hatch the following spring with the melting of the 

 snows. He states the larvae mature early and there is but a 

 single annual generation. All his records for collection are 

 for May, except one taken at Tupper Lake, N. Y., on August 

 16, 1905, and Barber's collection in Massachusetts, in July, 

 1910. The interesting fact that only perfect specimens were 

 found in our collecting would indicate either late maturing 

 larvae or a possible second generation. Gravid females were 

 not found in the collection made on June 25, the first being 

 obtained on July 9, and again on the 11th and 18th. 



The adults are sluggish, resting quietly and easily captured 

 by placing a small killing tube over them. The most interesting 

 observation is their non-biting habit, at least as far as man is 

 concerned. Several days and nights were spent in the shelter 

 during both sunny and cloudy weather, but never once did this 

 species offer to bite, though it was the predominant form there. 

 Contrary to Barber's experience, they were not attracted to 

 light, only two specimens being collected at the gasoline lantern 

 used during the summer. About 150 specimens were collected, 

 but this does not in any way represent the numbers present 

 in and about the shelter. 



Our doubt as to the identity of. the species was kindly 

 settled by Dr. H. G. Dyar, who exclaimed on being shown the 

 specimens, "That is my namesake, Ciilex dyariV He has now 

 placed it in the genus Cidicella, a genus intermediate between 

 Culex and Aedes. 



At the last moment, while examining larvae collected on 

 April 28, 1921, at Freeville, N. Y., for student use, we found a 

 single specimen of C. dyari. This location is about two miles 

 from what is described above as a natural habitat of this species. 

 Furthermore, a single reared specimen of which we have the
