 Federal Government, is reviewed.

 Female Mosquito.— .4 mt. Trop. Med. & Parasit., Liverpool, xvi, 

 no. 2, 20th July 1922, pp. 157-188, 23 figs. 



The results of a preliminary examination of the differential characters 

 of the genital armature of female mosquitos are recorded, fifty West 

 African species belonging to 16 genera having been used for the purpose. 

 In general well-marked differences were found between distmct genera 

 or subgenera, but onlv slight ones between species of the same genus. 

 The degree of resemblance is, however, very variable ; m the case 

 of Mimomvia and Ochlerotatus, for example, there are such notable 

 differences' between certain species that the authors consider them 

 almost generic.

Mosquitos received from the regions of Caracas and Maracay since 

 the previous report [R.A.E., B, x, 62] include, in addition to species 

 therein mentioned, Anopheles maculipes, Theo., A. {Arnhalzagia) 

 venezuelae, sp. n., which is described from one female, the characters 

 differentiating it from ^. pimctimacula, D. & K., being given, 

 Limatus durhami, Theo. ; Culex declarator, D. & K ; C corniger 

 Theo. ; Aedomvia squamipennis, Arr. ; Taemorhynchus {Mansoma) 

 titillans Wlk. ; " Psorophora posticata sayi, D. & K. ; P. hitzi, Theo. ; 

 P saeva D & K. ; P. ciliata, ¥.; P. {Janthmosoma) tovan, sp. n., 

 of which the female is described ; and Aedes {Finlaya) oswaldt, Lutz. 



Examination of a species of Arribalzagia from the Panama Canal 

 Zone indicates that the characters defined by Dyar for species of that 

 subgenus may be extremely variable. It seems probable that Anopheles 

 ■venezuelae may be in reality a variety of A. ptmctimacnla , D. cV K. 

 Further investigations on this point are being made.
