752 MOSQUITOES OF NORTH AMERICA 



Aedes auroides is one of the early spring species. Dr. Felt bred his only speci- 

 men from larvse taken with the other early species, while Mr. Busck found the 

 larvfe commonly associated with the other spring forms. 



Northern New York to New Hampshire. 



Dublin, New Hampshire, May and June, 1909 (A. Busck). Also reported 

 from Elizabethtown, New York (Felt). 



Aedes auroides is readily distinguished by the male genitalia or the larvse. 

 Well-marked females can be told by the thoracic ornamentation, but this is 

 subject to considerable variation, the brown mesial stripe becoming faint, or the 

 lateral coloration darkened, or both. We have felt obliged to use the char- 

 acters of the thoracic ornamentation to separate the species of this group in our 

 tables, because we know of no other characters, but it should be kept in mind 

 that they are variable and no absolute reliance should be placed upon them. 



It is probable that this species has a wider distribution than here given and 

 it may be the same as Aedes provocans Walker, which we recognize from more 

 northerly localities. We can not, however, decide this point with our present 

 material.

Original Description of Culex abserratus : 



Another very interesting larva was met with June 14 in a cold mountain pool at 

 Elizabethtown, N. Y., and may be easily recognized by the comb consisting of but six 

 to seven thorn-like scales arranged in a curved line, with a large, finely setose, 

 spatulate base and with a stout, apical spine. The air tube is about three times as 

 long as wide, tapering regularly and with double posterior pecten on the basal third, 

 each row consisting of twelve to fifteen closely set, stout spines, each bearing near 

 the basal third one large and usually a smaller tooth. This larva produced an adult, 

 Culex abserratus n. sp., which resembles C. impiger very closely and may be sepa- 

 rated therefrom by the posterior cross vein being its own length or more from the 

 mid cross vein, the thorax spotless, basal abdominal bands distinct, and the petiole 

 of the first submarginal cell one half the length of the cell. 



Descbiption of Female, Male, and Larva of Aedes abserratus: 



Female. Proboscis rather long, subcylindrical, uniform; labellas conically 

 tapered ; vestiture black ; setge on the labellse minute, outstanding. Palpi short, 

 about one-fifth as long as the proboscis, black, the setse moderate, bristly. 

 Antennfe filiform, the joints subequal, rugose, pilose, black, second joint slightly 

 thickened and paler; tori subspherical, with a cup-shaped excavation, luteous 

 brown, some white scales on inner side ; hairs of whorls sparse, moderate, black. 

 Clypeus rounded triangular, prominent, black, nude. Eyes black. Occiput 

 black, scales on vertex narrow, on the sides broad, yellowish-white on vertex, 

 with some golden-brown scales each side of middle line, dull white on the sides, 

 and an ill-defined lateral black patch, many short, erect, forked pale scales on 

 nape; bristles along margins of eyes black, those projecting between the eyes 

 pale.
