104 INSECUTOR INSCITliE MENSTRUUS 



Aedes aestivalis Dyar (as rep tans Meigen). 



A'edes canadensis Theobald. 



Aides trichurus Dyar (as punctor Kirby). 



A'edes vexans Meigen (as sylvestris Theobald). 



A'edes varipalpus Coquillett. 



A'edes curriei Coquillett. 



A'edes spencerii Theobald. 



A'edes cinereus Meigen (as fuscus Osten Sacken). 



The smaller number of species at Lake Pend d'Oreille is 

 partly accounted for by the brief time devoted to collecting, 

 the early forms, pullatus and trichurus, having probably dis- 

 appeared. A. curriei and spencerii are strays at Kaslo, as is 

 idaho'ensis at Sandpoint. The tree-hole species, varipalpus, 

 may be locally present at Lake Pend d'Oreille. Aside from 

 these, the lists are identical.

 A'edes spencerii Theobald, the fourth in abundance. 

 A'edes pullatus Coquillett, in timber at high altitudes.

 A'edes ftetcheri Coquillett. 

 A'edes stimulans Walker (group).
