A. hyrcanus and A. harhirostris, as was expected. Whether the larvae 

 of A . umbrosiis died as the direct result of the exposure to the sun could 

 not be ascertained, but its disappearance could hardly have been due 

 to the fouling of the water by the matter which fell in during the 

 clearing, as this also occurs in its normal habitat. Whatever the 

 causes they are apparently trivial ones, and when ascertained will 

 no doubt lead to the discovery of some less expensive and more 

 scientific method of control of Anophelines than by oiling the breeding- 

 places.

 xiii, pt. 1, May 1922, pp. 75-102, 3 figs. 



A collection of mosquitos from Paraguay includes the new species : — 

 Wyeomyia {Phoniomyia) fuscipes, Psorophora {Psorophora) pallescens, 

 P. [Janthinosoma) fiebrigi, P. (/.) piirpurascens, P. [Grahhamia) 

 varinervis, and Aedes (Ochlerotatus) stigmaticus. 



Sabethines collected in British Guiana include the new species 

 Wyeomyia bodkini and W . flavifacies . 



Aedes {Stegomyia) woodi, sp. n., is described from Nyasaland. 



Since the pubHcation of the author's paper on the African species 

 of Cidex [R.A.E., B, ii, 95], additional characters have been discovered 

 that aid in the discrimination of some closely allied forms and the 

 separation of the species into groups. The method of classifying 

 the genus is discussed. The Ethiopian species of Culex may be 

 divided into four main groups, to which must be added, perhaps 

 as distinct subgenera, the four other minor groups, Protomelanoconion, 

 Micraedes, Ctdiciomyia and Eunielanomyia, all of which show affinity 

 in one way or another with the fourth of the main groups. These 

 main groups are briefly considered. The first, bitaeniorhynchns group, 

 is evidently a natural one and includes all but two of the ringed-legged 

 species ; it is divided into two series, the bitaeniorhyncJms and the 

 sitiens series. The second group, the didtoni group, is not very clearly 

 marked from the third, the pipiens group. The latter includes the 

 majority of the Ethiopian species and is subdivided into the pipiens 

 and decens series. The fourth group, the rima group, corresponds more 

 or less to Dyar's subgenus Neoculex. The species dealt with include 

 Culex ornatothoracis, Theo., previously recorded as a synonym of 

 C. decens, Theo., var. invidiosits, Theo., but now thought to be distinct ; 

 C. kingianns, sp. n., from Sudan, South Nigeria and Ashanti ; and 

 C. {Ctdiciomyia) cinerellus, sp. n., from Uganda, Sudan and S. Nigeria. 

 Culex horridus, n. n., is proposed for Protomelanoconion fusca, Theo. 

 (Mon. Cul. V, p. 463, 1910), Sisfnsctis is preoccupied in Culex by Tricho- 

 rhynchus fuscus, Theo. ; Culex albiventris, n. n., is proposed for Eunie- 

 lanomyia inconspicuosa, Theo. (Mon. Cul. v, p. 240, 1910), as this is 

 preoccupied by Aedes inconspicuosus, Theo., both species really 

 belonging to Cidex. 



Cidex tigripes, Grp., should be transferred to the genus Lutzia, which 

 is regarded as distinct from Ctdex. 



Notes are given on the mosquitos collected at Karwar, North 

 Kanara, India, which include two new species, Uranotaenia rccondita 

 and Aedes [Finlaya] cogilli. 



Other new species, recorded from Northern and Eastern Australia, 

 are: — Aedes [Chaetocniiomyia) humeralis, A. {Finlaya) auridorsum, 

 A. (F.) qnincpiclineatus, A. (F.) pectmiosus, A. (? Skusea) aiirimargo, and 

 Cidex \Lophoceratomyia) hilli. Aedes {Chaetocniiomyia) spinosus n. n..
