NOTES ON THE DIFFERENT GENERA 509 



with ventral and apical scales, and a median ventral apical tuft, and with very 

 densely scaled palpi in the female, and densely scaled proboscis. It seems to be 

 mainly an Asiatic and East Indian genus, but three species occur in Africa and 

 one in Australia. They are mostly sylvan species and bite severely. 



Fourteen species are known. Five are malaria carriers (vide list, p. 566). 



Genus. Nyssorhynchus, Blanchard ; Laverania, Theobald. 



" Mono. Culicid.," 1910, iii, p. 14 ; v, p. 55, Theobald ; Compt. rend. heb. Soc. Biol^ 

 No. 23, p. 795, Blanchard. 



A group of small, closely allied species found in Asia, Africa and Australia, 

 twelve out of the twenty species coming from India. 



The thorax is covered with narrow curved and spindle-shaped scales, abdomen 

 with small, flat or narrow curved dorsal scales, especially on the apical segments or 

 in patches ; the legs are always banded or spotted with white, and the tarsi have as 

 a rule one or more pure white segments. (This banding and spotting is of no 

 generic value, however.) 



The species show considerable seasonal variation. The type of the genus is 

 N. maculatus, Theobald. 



Three are malaria carriers (vide list, p. 566). 



Genus. Cellia, Theobald. 



" Mono. Culicid.," 1903, iii, p. 107 ; 1910, v, p. 67. 



Very marked Anophelines, with densely scaly abdomens, the scales irregularly 

 disposed on the dorsum and forming dense lateral tufts ; thorax with flat spindle- 

 shaped scales ; palpi densely scaled and also the wings. 



The type of the genus is the African C. pharoensis, Theob. It is represented in 

 Asia by C. kochii, Donitz ; in West Indies and South America by C. argyrotarsis , 

 Desvoidy, and C. bigotii, Theob. ; in Africa by C. squamosa, Theob., etc. 



C. argyrotarsis, Desvoidy, and C. albimana, Wiedemann, are undoubtedly 

 malaria bearers. 



Genus. Neocellia, Theobald. 



"Mono. Culicid.," 1907, iv, p. in. 



Allied to Cellia, but has no lateral scale tufts. Three species recorded from 

 India. 



Genus. Kertdszia, Theobald. 



"Ann. Mus. Nat., Hung.," 1905, iii, p. 66. 



This genus has the thoracic scales hair-like, except a few narrow curved ones 

 in front ; abdominal scales long, broad and irregular. 



A single species, K. boliviensis, Theob. from Bolivia. 



Genus. Manguinhosia, Cruz. 



The thorax has narrow hair-like curved scales and some broad straight scales ; 

 others spatulate on the sides. Abdomen with fine hairs, except the last three 

 segments which are scaly. Tufts of scales on the hind femora. Wing scales 

 lanceolate. 



The type is M. lutzi, Cruz, from Brazil.
