Genus Reedomyia. 257 



articulating segment; mentum triangular, 10-11 teeth on each 

 side of the apex; comb of eighth segment composed of 8 to 13 

 scales arranged in a single irregular row on each side, scales 

 elongated and fringed with short hairs at sides and apex ; siphon 

 short and thick with the two rows of the spines 15 to 21 in 

 each row, each spine has a few small teeth basally on one side ; 

 anal gills short. 



It is easily identified by its unusually long form. They seem 

 to be normally found in holes in tree stumps where water collects. 

 The larva approaches that of Stegomyia fasclata. 



Dr. Dyar states that the female deposits her eggs singly or in 

 patches at the edge just below the surface of the water, and there 

 they remain until spring. 



American observers have identified Say's species, I presume 

 from the type, but in none sent me has the thorax been 

 dark blue, and I therefore do not feel at all sure that this is what 

 Say described originally. 



In consequence I append Say's description : — 



"Body brown; thorax rather dark blue, with white hairs on either side; 

 pleurae with two white, hairy spots ; abdomen with a triangular white 

 spot on either side of the base of each segment; these spots correspond 

 with bands across the belly, which are twice interrupted, so that each 

 band shows three spots, on each segment, the middle spots forming a 

 sort of stripe along the belly. Legs yellowish, with brownish hairs ; 

 femora naked, blackish above, at the apex. 2J lines." 



Genus REEDOMYIA. Ludlow. 

 Canad. Entomo., 1905, Vol. XXXVII., p. 94 (1905). 



Head densely covered with slender curved scales and flat 

 lateral ones, and numerous upright forked scales. Palpi short in 

 ¥ , long in $ . 



Thorax with narrow-curved scales. Scutellum with flat 

 scales, usually shiny white or silvery. Miss Ludlow says that 

 the prothoracic lobes appear to be stalked, the stalks running in 

 a curve up the cephalic aspect of the thorax and the lobes end 

 in a kind of cap, reminding one of a mushroom. 



Fork-cells rather short ; scales rather broad and truncated ; 

 cost a slightly spinose.
