272 Professor Williston on the 



1. H^^magogns sjphndens, n. sp. (PI. IX., figs. 31, head 

 of ? ; 31a, palpus; 31^, claw of $ ; 31c, wing.) 



$ . In ground-colour deep black, the base of the femora, and 

 the coxae in part, somewhat yellowish, Occiput, mesonotum aud 

 scutellum wholly covered with brilliant green and coppery squa- 

 niulas ; pleurte densely snow-white squamulate. Abdomen brilliant 

 steel-blue, in some reflections black ; a spot on the sides of each 

 segment snow-white. Legs blue, like the abdomen, shining black 

 in some reflections ; the undersides of the femora, towards the 

 base, with white squamula^. Wings hyaline, somewhat brownish 

 ill front, squamula3 black, evenly distributed. Length 5 mm. 



Eight specimens. 1000 feet. The single male 

 specimen was injured after the drawings were made. It 

 does not appear to differ, however, from the female. The 

 colouring must be much like that of Culex cyaneus, save 

 of head and thorax.

A single female specimen, to which Lynch's descrip- 

 tion applies well, and whom I follow in the above-quoted 

 synonymy. That 0. fasciatus, Fabricius, is different 

 from C. fasciatus, Wiedemann, seems evident, but that 

 the present species is the same as the latter is not so 

 fully apparent to me. Wiedemann says that " An den 

 vordern Fusswurzeln ist die aiisserste Basis der ein- 

 zelnen Gheder schneeweiss,'' while it is only the first 

 joint that is thus marked in this species. 



2. Culex, sp. 



Several specimens of a luteous species, which are too 

 ill-preserved to describe.
