were for the first time detected by the party, interesting animals 

 of the order under consideration were also collected. The speci- 

 mens are in my cabinet. 



CULEX Linn. 



1. C. PUNCTiPENNis. — Body dark rufous, covered with cinereo- 

 ferruginous hair ; feet elongated ; wings maculated. 



Inhabits the United States. 



Orbits, bright cinereous ; eyes deep black ; antennge and pro- 

 boscis deep fuscous or blackish immaculate ; thorax dark rufous, 

 with obsolete blackish lines, and covered with cinereo-ferrugin- 

 ous hair; wings hairy, dusky, with a hardly perceptible pale 

 band beyond the middle, and obsolete dusky spots ; scutel gla- 

 brous, dark rufous, with a longitudinal bluish vitta ; halteres 

 yellow at base ; feet elongated, deep fuscous or blackish ; pectus 

 each side above the posterior feet plumbeous. 



It is probable this is the species which Fabr. considers as the 

 same with the pulicaris of Europe ', it is common on the Missis- 

 sippi, and troublesome to travellers. When the insect is at rest, 

 the wings being incumbent, one on the other, the pale band is 

 very distinct ; when recent, the eyes are greenish-blue. I ob- 

 served this species in considerable numbers on the Eastern shore 

 of Maryland. The dusky spots on the wings of this species, are 

 occasioned by the thicker growth of hair in those parts. 



[Belongs to AnopJides : Wiedemann has changed the name to 

 A. crucians. — Sacken.] 



2. C. 5-fasciatus. — Body clothed with cinereous hair ; abdo- 

 men annulate with blackish. 



Inhabits the Western States. 



Eyes deep black ; antennae fuscous, region of the base paler ; 

 proboscis black ; thorax with a dilated dorsal fuscous vitta ; pectus 

 each side varied with blackish ; halteres entirely whitish ; scutel 

 glabrous ; wings with dusky nervures, immaculate ; feet mode- 

 rate, fuscous ; thighs whitish ; abdomen cinereous ; tergum with 

 five black, broad fasciae ; tail black above. [ 1 1 ] 



Length about one-fifth of an inch ; proboscis one-tenth of an 

 inch. 



This is an exceedingly numerous and troublesome species 

 We found them in great numbers on the Mississippi in May and 

 1823.]
