long's second expedition. 241 



Inhabits Middle States. 



9 Body deep black, densely punctured j front with a white 

 spot surrounding the base of each antennae ; antennae black-brown, 

 three basal joints and mandibles rufous; thorax with the collar, 

 obsolete line over the wings, dilated posterior teeth and scutel, 

 ferruginous ; wings dusky on the terminal margin ; feet rufous ; 

 tergum black-brown ; two distant bands on the first segment, of 

 which the first is obsolete, and the other is interrupted in the 

 middle, second [356] and third segments each with a band on 

 their posterior margins, pale yellow ; remaining bands indistinct. 



Length from three-tenths to nearly seven-twentieths of an 

 inch. 



Much smaller than the preceding, and about equal in size to 

 E. mercnfus Fabr., from which it differs by various characters, 

 and particularly by the much more dilated form of the posterior 

 thoracic teeth. During rainy or windy weather, this insect 

 secures itself to the edge of a leaf or to the small branch of a 

 bush, by its mandibles, retracts the feet to the body, and projects 

 the antennae forwards. 



ORDER DIPTERA. 



ANOPHELES Meig. Wied. 



A. 4-MACULATUS. — Pale brownish ; wings with four fuscous 

 spots. 



Inhabits North-west Territory. 



Thorax dull cinereous ; two oblique, brown lines confluent be- 

 hind and reaching the posterior edge ; a broad, lateral, brown 

 line also extending the whole length of the thorax; wings hyaline, 

 the nervures hairy, forming two blackish spots near the middle, 

 placed longitudinally ; and two others nearer the tip on the bi- 

 furcations of the nervures, placed transversely ; scutel dull 

 ochreous, dusky in the middle ; feet black-brown, incisures at 

 tip of the thighs and of the tibiae, yellowish ; tergum whitish, a 

 little varied with dusky. 



Length 9 to the tip of the wings more than three-tenths of an 

 inch. ^ [357] 



Closely allied to the maculqwnnis Hgg. I have not seen the 

 male. Wiedemann informs me that my Culex punctipennis is a 

 true Anopheles, an observation which I have found to be correct.
