36 FAUNA OF MAYFIELD'S CAVE. 



Anopheles quadriraaculatus Say. 



SAY, Etom. Works, ed. Le Conte, I, 241; n, 39 (Atlantic States, Canada, Southern 

 Europe). ALDRICH, Cat. N. A. Dip., 1905, 122. 



A single specimen of this species was taken just inside the door, 

 September 24, 1903. 



Culex pipiens Linnaeus. 



LINN^US, Syst. Nat., 12th ed. ALDRICH, Cat. N. A. Dip., 1905, 130. 



A few of this species were taken near the mouth during the fall. 

 Two were found at "8" during March and one near the mouth in April. 

 It is found in recesses of the wall or ceiling and probably hibernates in 

 the cave to a limited extent. 



Family MYCETOPHILIDAE. 

 Polylepta leptogaster Winnertz. 



WINNERTZ, Mon., 746 (Europe). ALDRICH, Cat. N. A. Dip., 1905, 141 (Europe and

Rymosia filipes Loew. 

 LOEW, Cent., ix, 36 (Connecticut). ALDRICH, Cat. N. A. Dip., 1905, 145. 



Fairly common near the mouth and back to beyond the second turn 

 (to "8")> where there is almost absolute darkness. 



Mycetophila discoidea Say. 

 SAY, Jour. Acad. Phil., vi, 153 (Indiana). ALDRICH, Cat. N. A. Dip., 1905, 146. 



Not common in the cave. Only a few have been taken. They have 

 been found only in fall or spring but that is possibly a coincidence. 

 They occur usually on the wall or roof but one was found on the under 

 side of a stone at " 6. " 



Mycetophila ichneumonea Say. 



SAY, Jour. Acad. Sci. Phil, in, 16 (Pennsylvania). ALDRICH, Cat. N. A. Dip.,

 October. 



Mycetophila obscura Walker. 



WALKER, List. Brit. Mus., I, 101 (Canada). ALDRICH, Cat. N. A. Dip., 1905, 146 

 (Canada and White Mountains). 



Fairly common from the mouth to " 11, " and to be found occasionally 

 as far as to the mound. This is one of the abundant Mycetophilidse. 

 Taken also in Twin Cave at Mitchell. Its known distribution includes 

 New Jersey also.
