98 INSECUTOR INSCITI^ MENSTRUUS 



in the mountains instead of six as in California. This is again 

 conditioned by the climate. Frequent rains are conducive to per- 

 manent pools in which Aides do not thrive. The Culex, 

 Culiseta, and Anopheles that do frequent such places are the : 

 same as in California, minus the tropical element, but without 

 any additional species, all resulting in a small mosquito fauna. 



Aedes aloponotum, new species. 



Mesonotum light red, with three narrow dark brown lines 

 in the integument; vestiture of narrow curved bronzy brown 

 scales, becoming straw-color about the antescutellar space. 

 Abdomen black, with basal segmental whitish bands, widening 

 at the sides ; venter with median black patches almost forming 

 a band. Wing-scales black, with white ones intermixed on 

 costa and first vein, some also on forks of second and fourth 

 veins. Legs black ; femora white within nearly to tip, a white 

 knee-spot; tarsi with br^d basal whitish rings, the last joint 

 half white. Claws toothed. 



Type, female. No. 31543, U. S. Nat. Mus. ; Lake Cushman, 

 Washington, June 28, 1917 (H. G. Dyar). 



Two other females were taken at the same place; one has 

 the integument of the mesonotum dark brown, but with the 

 same foxy-red vestiture.

 stages unknown. |

 27, 1917, is referred to increpitus pending further information. 



Aedes curriei Coquillett. 1 



A coast species breeding in tidal pools, not distinct from 

 the inland curriei. A specimen was seen on the marsh at 

 Bellingham, Washington, May 31, 1917, and others were cap- 

 tured at Alki Point, Seattle, Washington, June 20, 1917.
