former contending that this name should be applied to the present species, the 

 latter that it was not so applicable, but probably the same as Oulex pipiens 

 Linnaeus. After careful consideration we incline to agree with Mr. Aldrich; 

 we have, accordingly, made the name consobrinus a synonym of pipiens and 

 use the name inornatus for the present species. The adults are supplied with 

 scales on the cross-veins, but these are sometimes very few in number, or 

 altogether lost by abrasion, so that the species is liable to be confused with 

 impatiens. It can be distinguished by the color as described under that species. 

 The characteristic venation is less stable in these species than in the others of 

 the genus, and individual males occur which are liable to be mistaken for a 

 Culex. The large size, the weak plumosity of the antennae, the form of the palpi 

 and the poorly developed lateral ciliation of the abdomen, are an assistance to 

 identification in such eases.
