A new genus, Acanthocoiiops, is erected and contains two species, 



A. spinosifrons, sp. n., and A. albiventris, de Meij., of wliich the former 

 is the genotype. 



Balfour (A.). Mosquito Breeding in Saline Waters. — Bull. Ent. 

 Res., London, xii, pt. 1, June 1921, pp. 29-34. 



The subject of mosquitos breeding in salt or brackish waters is of 

 practical importance in anti-malaria work, for it has often been 

 suggested that ordinary mosquito breeding-places might be abolished 

 by the introduction of salt or sea water, and in some cases this pro- 

 cedure has actually been carried into effect. In the case of certain 

 species of mosquito, however, it is useless or worse than useless. 



Moreover, information on the efficiency of larvicides in saline waters 

 is still defective. 



In view of this, a number of annotated references on this subject 

 are given, supplementary to those furnished by Dr. Dalziel [R.A.E., 



B, ix, 41] and dealing almost entirely with mosquitos known to be 

 vectors of disease.

Tabanidae. — BitU. Ent. Res., London, xii, pt. 1, June 1921, 



pp. 41-62, 2 plates, 21 figs. 



The life-history, habits and developmental stages of Tabanus 



aprepes, Tayl., and T. riifinotatus, Big., are described at length, and 



similar details, so far as they are known, are given rather more briefly 



concerning T. nigritarsis, Tayl., and Silimis notatiis, Ric.

The new species described are: — Anopheles fiaviceps, from the 

 Anglo-Egyptian Sudan; A. amictus, from Queensland; Megarliimts 

 ( Toxorhynchites) kempi, and M. {T.) gravely i, from India ; M. (T.) klossi, 

 from the Malay States ; Aedes {Stegomyia) dendrophila, from the 

 Gold Coast; A. {Ochlerotatus) asJnaorthi, from West Australia; A. 

 {Skiisea) punctipes, from Upper Burma ; Rachionotomyia aenca, from 

 the Malay States ; and R. piirpurata, from Fiji. 



The suggestion that Anopheles immacnlatus, Theo., may be an 

 albinoid form of A. vagus, Don., is supported by the fact that an 

 examination of the male hypopygia has revealed no tangible difference 

 between the two forms. Besides the typical form of A. leucosphyrus, 

 Don., another well-marked form, A. leucosphyrus var. hackeri, occurs. 

 They are probably, however, not specifically distinct. 



The author does not agree with Swehengrebel [R. A.E., B, viii, 136] 

 in attributing Anopheles {Nyssorhynchus) anmilipes var. mohiccensis 

 to that species, and considers that it is really a variety of A . ptinctulatus, 

 Don. He follows him, however, in treating A. tessellatiis, Theo., as 

 a variety only of A. pnnctulatus. 



Opifex fuscus, Hutton, originally described from New Zealand as 

 a Tipulid, is actually a Culicine mosquito. It is difficult to place it 

 precisely in relation to the other genera ; it seems nearer to Aedes 

 than to Culex. 



Both sexes, apparently of Aedes {Skusea) funerea, Theo., have been 

 received from Amboina. Another pair from Ceram are regarded as 

 A. funerea var. ornata, Theo. Lepidomyia lineata, Tayl., is regarded 

 as a synonym of this variety.
