AQUATIC INSECTS IX NEW YORK STATE 427 



Culex, the plane of the margin being about at right angles 

 V, ith the long axis of the tube. On the dorsum of thorax is a 

 pair of short forked hairs just caudad of the trumpet; on the 

 metathorax is a transverse row of slender setae, and caudad 

 of the base of the posterior margin of the wing are five or six 

 Tather long setae. The two stellate hairs on the first abdominal 

 segment are very conspicuous. The rest of the segments each 

 with a few subdorsal hairs; on the posterior end of the lateral 

 margin of segments 4, 5 and fi is a single long one, and on 7 and 8 

 a conspicuous fan of hairs [flg.5]. The swimming paddles are 

 rather small and with cilia on posterior margin. The thorax in 

 mature specimens is dark brown, the abdomen paler. 



Described from specimens kindly furnished by Prof. John B. 

 Smith. 



Genus uhanotaeivia Arribalzaga 



This genus possesses in most respects the same characteristics 

 as Culex and Aedes; it differs from Culex however in having 

 short palpi in both sexes, agreeing in this with Aedes, but differs 

 from the latter in having violet blue scales on the thorax. The 

 palpi of b6th sexes are two jointed, the basal joint globular, 

 nearly as large as the basal joint of the antennae, the apical 

 joint small, conical and pointed; differing thus from the cylindric 

 palpi of the female Culex.

 "Wings unspotted; abdomen dorsally brownish, thorax 

 tawny brown with a median dorsal, and three lines on the 

 pleurae, metallic blue; tarsi brownish, unhanded." Description 

 of Osten Sacken. 1.SG8. 2:47. "Fuscous, the frons, a median 

 thoracic line and stripes on pleurae metallic blue; bases of coxae 

 and femora pale; apexes of the. femora and tibiae snowy. Front 

 blackish, with a metallic blue reflection along the eyes, spe- 

 cially in the middle. Antennae blackish, scapus tawny; those 

 of the male apparently 15 jointed (13 plus two), flagellum with 

 12 beautifully bearded joints; a 13th elongated, linear joint has 

 some scattered hairs, but no beard like the preceding ones. 

 Proboscis long, reaching in the male if bent backward, to about 

 the middle of the abdomen; rather conspicuously incrassated 

 at the tip; perhaps still longer in the female (abdomen of my 

 female injured); thorax brownish, tawny, darker above, paler 

 on the pleurae; a metallic blue longitudinal line along the middle 

 of the thorax reaches the scutellum ; three similar marks on the 

 pleurae, the upper of which is in the shape of a short line run-
