CHARACTERISTICS OF LARV.E OF ANOPHELINA. 139 



seventh seg-ments inclusive (PI. XVIII, fig-, h, PI. XXIV, 

 fig. d). Average radius 0"166 mm. Average relation of 

 filament to leaflet and filament together as 0'26 to one ; 

 maximum 0"o4; minimum 0"18. The palmate hairs are 

 characteristic in exceptional length, breadth and number of 

 leaflets, and this together with the frontal hairs make the 

 species unmistakable. 



Habitat. — Found in a quick-running streamlet under over- 

 hanging banks in company with the larger variety of f unesta . 



Season. — Fairly numerous in the one stream in April, 

 May, June and Sept., 1905, rare in Jan., Felj., May, 1906. 



Eolation to Malaria. — No evidence of any connection.

Theobald (vol. Ill, p. 99) writes as follows : 



"Closely related to N. maculipalpis, but the palpi are 

 not mottled and are somewhat longer ; the two white apical 

 bands are farther apart. The hind tarsi have also different 

 ornamentation ; the second hind tarsus has a small black 

 patch near its base ; the metatarsus is mottled with white 

 and black, and has a broad white apical band like the first 

 tarsal. The last two hind tarsi only being all white. 



"^It is subject to much variation. 



" One specimen in the series has the last palpal joint black 

 at the base, so there are four, not three, pale bands ; the 

 wings are also darker scaled, the third long vein being 

 entirely black." 



The legs and wings of N. maculipalpis are thus 

 described (p. 97) : 



" Legs black, with the femora and tibife, and to some 

 extent the metatarsi, with small clear white spots, first fore 

 tarsi with apical white bands, mid-tarsi plain ; in the hind 

 legs the last three and apex of the first tarsi pure white. 



" Wings clothed with mostly dusky -black narrow elongate 

 slightl}^ clavate scales, with some white areas, as follows : On 

 the costa five pure white spots, the two apical ones and the 

 fourth spreading on to the first long vein, which is also
