Original Description of Cutlex damnosus : 



Rostrum and tarsi annulate with white. 



Inhabits Pennsylvania. 



Head above with rather long yellow-ferruginous hair; antennae pale-brownish; 

 rostrum blackish, with a broad white band on the middle; thorax black, with three 

 cinereous lines, and clothed with yellow-ferruginous short hair; scutel dull testa- 

 ceous; pleura grayish; feet pale, covered with blackish hair; joints of the tarsi, ex- 

 cepting the first, whitish at their bases; tergum brown, basal margins of the seg- 

 ments cinereous-whitish. 



Length a quarter of an inch. 



This is one of the most common and troublesome of our mosquettoes. It seems to 

 correspond in some degree with the eingulattis Fabr., although we must infer from 

 his description, that the posterior tarsi only are annulated. Wiedemann considers 

 the cingulatus as the male of his molestus, of which all the tarsi are annulated. 

 like those of our species. I feel however perfect confidence in the description of 

 Wiedemann, and therefore must consider our species distinct, inasmuch as the 

 thorax is not " lateribusque niveis;" and from the laudable accuracy of that author, 

 I cannot suppose that he would have overlooked the annulation of the proboscis, 

 which certainly exists in this species. 



Description of Female, Male, Larva, and Egg of Aedes thjniorhynchus : 



Female. Proboscis rather long, moderately slender, cylindrical, the labellse 



conically tapered ; vestiture black with a white ring at middle ; setse minute, 



black, those on labellae more prominently outstanding. Palpi short, rather 



stout, about one-fifth the length of the proboscis, black scaled, the tips white; 



setae moderate, black. Antennae with the distal joints longer than the basal ones, 



rugose, black, pilose; tori subspherical, with a cup-shaped apical excavation, 



brown, a patch of silvery scales on inner side ; hairs of whorls moderate, sparse,
