104 ENTOMOLOGY FOR MEDICAL OFFICERS 



4. UranoT/ENIA Series. 



Uranofania, Arribalzaga. Head and scutellum covered with imbri- 

 cating squames ; there may be some darts on the head and some sickles 

 on the scutellum. Usually there are some elliptical squames on the 

 scutum. Proboscis swollen at tip. Palpi short in both sexes. Some 

 of the wing-scales may be broadly triangular or even heart-shaped. 

 Fork-cells (particularly the 2nd marginal) very small. Small or minute 

 mosquitoes, often with beautiful blue markings, found in tropical latitudes 

 all round the globe ; many species. 



Anisocheliomyia, Theobald. Differs from Uranotania in the setting 

 of the squames of the head, and in the claws of the male, one of which 

 in every foot is leaf-like. 5 species ; South America, India, Australia. 



Pseuduranotania, Theobald. As Uranotania, but the fork-cells are 

 not quite so small. 3 species ; South America and Philippine Islands. 



5. PsoROPHORA Series. 



Psorophora, Robineau-Desvoidy. Head with some darts, but chiefly 

 covered, like the scutum and scutellum, with broad elliptical squames 

 that do not much overlap. Legs shaggy with outstanding scales. 

 Palpi long in the male, short in the female. Large black mosquitoes 

 with a metallic sheen, found only in America (including the West 

 Indies). The larvse are said to be extremely rapacious. 



lanthinosoma, Arribalzaga. Head with some darts but chiefly covered 

 with elliptical squames which are closer set than and do not lie so flat 

 as those of Psorophora. Scutum with elliptical squames and hairs. 

 Scutellum with elliptical squames. Legs— more particularly the hind pair 

 — somewhat thickened and roughened with outstanding scales. Palpi long 

 in the male, short in the female. Mosquitoes of moderate size with metallic 

 sheen (bronze or purplish), found only in America and the West Indies. 



^dinus, Lutz. Head with darts and elliptical squames. Scutellum 

 with elliptical squames. Middle legs with some outstanding scales, i 

 species ; Brazil. 



Gilesia, Theobald. Head, scutum, and scutellum covered chiefly 

 with flat-lying elliptical squames which do not overlap. Wing-scales 

 broadish. Palpi of the female about one-fourth the length of the 

 proboscis, i species ; Australia. 



Maillotia, Sergent. Head with some darts but the predominant 

 scales of the head, scutum, and scutellum are short, broad, curved 

 scales which are much like the elliptical squames of Janthinosoma. 

 Wing-scales narrow, i species ; Algeria. 



6. MuciDus Series. 



Mansonia, Blanchard { = Pneumaculex, Dyar). Head 

 shaggy with darts, broadish sickles, and — at the sides — loose
