Described from 1 female and 1 male, taken by Mr. A. H. 

 Ritchie in the burrows of a Cerambycid beetle in the bark and 

 cambium of Pimento, in the northern part of Jamaica, in April, 

 1916. 



Closely related to P. antennatus, which is known only from 

 Illinois, but easily recognized by the pale legs, the differently 

 colored antennas, the absence of a fore-tibial tooth, the shorter 

 head, and the shorter terminal bristles, which in antennatus 

 are very nearly twice the length of the tube. 



NEW AEDES FROM THE MOUNTAINS OF 

 CALIFORNIA 



(Diptcra, Culicidcc) 



By HARRISON G. DYAR 



The following new species of Aedes were met with in an 

 investigation of the mosquitoes inhabiting the Sierra Nevada 

 Mountains of California. These species are all of the early 

 spring group, breeding in the pools left by the melting snow, 

 with a single annual generation. At an altitude of 6,000 feet, 

 pupas were abundant May 25, and by the first week in June 

 the breeding was complete ; even the pools that still contained 

 water or had only just thawed out were empty. Adults ap- 

 peared by the first of June, and by the 15th the woods were 

 filled with them in all directions.
