INSECUTOR INSCITI^ MENSTRUUS 113 



(E. Hearle) ; Agassiz, British Columbia, May 33, 1919 

 (E. Hearle). 



The occurrence of this form in the Eraser Valley is unex- 

 pected, and perhaps forms a transition to fletcheri fletcheri. 

 The specimen from Mount Cheam, British Columbia, recorded 

 in the monograph, is a normal fletcheri. On the other hand, 

 specimens from forested Ontario have much the appearance 

 of aloponohim, except for the absence of the red mesonotal 

 integument ; but these are females and may prove to be 

 riparius, so that positive conclusions cannot be drawn. 



Species 4 



Aedes stimulans mississippii, new^ subspecies. 



Mesonotum uniformly brownish, dark brown centrally, gray 

 on the sides, the marking not contrasted ; abdomen with basal 

 segmental white bands ; tarsi with moderate or rather narrow 

 white rings at the bases of the joints ; wings with many white 

 scales, especially in the costal region. Male hypopygium as in 

 stimulans, but the setae on the outer lobe of the side-piece very 

 coarse, distinctly coarser than the general vestiture. 



Types, male and female, No. 22884, U. S. Nat. Mus. ; Elec- 

 tric Mills, Mississippi, "from water in tree-stumps" (J. A. 

 LePrince). 



A southern race of stimulans. The peculiar habitat indi- 

 cated by the single collection needs amplification. 



Aedes stimulans classicus, new subspecies.
