CULEX Linn. 



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

 {'errui;inous hair ; feet elongated ; wings maculated. 



Inhabits the United States. 



Orbits, bright cinereous; eyes deep black ; antenna) and pro- 

 boscis deep fuscous or blackish immaculate ; thora.K dark rufous, 

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

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

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

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

 yellow at ba.se ; 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 j^iiluan's 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 Anophrlcs : Wiedemann has changed the name to 

 A. cri/riaiis. — SacKEN.] 



2. C. 5-i'ASClATUS. — Body clothed with cinereous hair ; abdo- 

 men annulate with blackish. 



Inhabits the Western States. 



Eyes deep black ; antennae fuscous, region of the ba.se palbr : 

 proboscis black ; thorax with a dilated dor.sal fuscous vitta ; pectus 

 each side varied with blackish ; halteres entirely whitish ; scutel 

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

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

 tive black, broad fasciae ; tail black above. [H ] 



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 3Ii.ssi.ssippi in May and 

 182;].]
