 6 mm. (?.

46. ANOPHELES FERRUGINOSUS, Wied. ("A. Z. I." p. 12). 



An. Walker i, Theobald (?.) 



Wings unspotted ; tarsi unhanded, nearly black ; abdomen 

 unbanded, dusky brown with yellow hairs ; thorax deep red- 

 brown with linear markings. Stems of halteres white, with 

 brown knobs. 



Original description : — 



Antennae and palpi brown, the latter more dusky with a little white 

 at the joints; thorax intense red-brown, but only in certain lights, if seen 

 from behind whitish, and it then exhibits linear stripes, but looking 

 backwards without stripes ; abdomen dusky brown with yellowish hairs ; 

 veins of the wings with brown scales ; halteres intense white with brown 

 knobs ; legs shorter than in An. crucians, brownish-black with yellowish 

 femora. 



No material exactly answering to this description has been received 

 in the British Museum, but Mr. Theobald suspects it may be the same 

 as his An. Walheri, though he considers it can be neither C. qtdnque- 

 fasciatus, Say, or A7i. crucians. Walker.

An. ferriiginosus, Wied. (?). 

 Plate xi, hg. 2a, Wing of ? ; 2b, Fork scale from nape. 



Closely resembles An. bifurcatus, L., differing only in the 

 iorm of the fork-scales of the nape, which are forked in the 

 present species and fimbriate in bifurcatus. The base of the 

 hinder fork-cell is also said to be placed much farther outside 

 that of the anterior than in that species, but the relative position 

 is not very constant in either. Mr. Theobald makes the follow- 

 ing observations as to his new species : — 



" Tliis species closely resembles the European A. bifurcatus, but 

 differs from it in regard to the head ornamentation, the browner appear-
