294 GNATS OR MOSQUITOES — CHAPTER XII 



1. ANOPHELES BIGOTII, Theob. (Monog. I, p. 185). 

 Plate viii, fig. 5, Wing of Female (diagrammatic). 



$ . — Wings with the costa black, including the apex and base, 

 interrupted bj' two obvious white spots, one near apex, the other||, 

 the fork-stems with a third small dot a little further in. The sub- 

 apical spot extends right across the wing, involving both branches 

 of IV, and there are lighter interruptions to the fringe at all the 

 long junctions. Fore legs with the upper three tarsal joints 

 apically white ringed, the fourth all black, and the fifth all white; 

 hind, with the last three tarsals and the apices of the other two, 

 white. Thorax dark brown with four longitudinal lines of rather 

 fiat white scales, the two median ones rather close together. 



I have not seen this species, as the single type specimen is in a private 

 collection. The decoration of the thorax easily distuiguishes it from all 

 the other species with white hind feet. Head brown with white curved 

 scales, and fiat ones at the sides ; antennae brown, with second joint 

 nearly as long as the next two, together ; palpi brown, with apex and 

 four apical bands to joints white. Abdomen steely-black, rather 

 densely clothed with flat yellow scales on terga, and with white on the 

 venter. Length. — 6 mm. 



Habitat.— Q\\\\\. 



Observations. — (There is a single specimen in Bigot's collection, 

 labelled by him as " j^tmctipennis " ; as, however, the name is already 

 used by Say for a quite different species, it cannot stand.) 



2. ANOPHELES ALBIMANUS (Wied.) (" A. 'A. I.," p. 13). 



No specimens exactly referable to the description of this 

 species have reached the British Museum, but it is clear from 

 the name and general context of the description, that the fore 

 tarsi, and probably those of all the legs, had wliite end-joints. 

 The species most nearly resembling it is An. Bigotii, and there 

 seem no very strong reasons why that species should not be 

 regarded as a synonym of Wiedemann's. The specimens from 

 Jamaica, referred to this species in the first edition, were cer- 

 tainly wrongly identified, as in the light of tbe abundant material 

 now available, there can be no doubt that they are examples 

 of An. argyrotamis, Desvoidy. The following is the original 

 description : — 



Fuscous, the abdomen with large, trianguliu-, grey spots ; the wings 

 with dusky spots ; the apices of the tarsi snow-white. Length, 2fj lines 

 (German), ? . 



Apices of the joints of the palpi snow-white. Each segment of the 

 abdomen with a grej', triangular spot, the aj^ex of which is directed
