BIONOMICS OF ANOPHELINA 255 



Anopheles (Cellia) bigot ii, Theobald. Palpi with four white bands, one 

 at the apex. Thorax brown with four greyish longitudinal lines. Legs 

 brown, banded ; apical band on metatarsus and first two tarsi of fore legs, 

 and last joint white ; last three tarsi and apex of the first of the hind leg 

 pure white. Costa dark with three white spots. From Chili. 



Anopheles (Cellia) brasiliensis, Peryassu. Allied to argyrotarsis (see 

 below), but the three spots on the wing costa are larger. From Brazil. 



Anopheles (sensu restricto) mattogrossensis, Lutz and Neiva. Palpi 

 dark and unhanded. Thorax dark in the centre and yellowish at the 

 sides. Abdomen dark with silvery hairs. Legs dark with a bronze sheen, 

 with indistinct apical rings to the upper segments. Wing dark with two 

 brownish yellow spots on the costa. From Lake Mandicore, Motto 

 Grosso, Brazil. 



Anopheles (Cyclolepidopteron) grabhami, Theobald. Palpi densely 

 scaled, but unhanded. Thorax slate grey, mottled with brown. Legs 

 brown and spotted. Costa black with a yellow spot at the tip of 

 the wing. Larva with a characteristic white mark on its thorax ; 

 frontal hairs simple and unbranched ; palmate hairs from second to 

 seventh segments ; leaflet long and without any definite filament. From 

 Jamaica and Cuba. 



Anopheles (Cellia) argyrotarsis, Robineau-Desvoidy. Palpi with 

 three white bands, one including the apex. Legs yellowish, the apex 

 of the first tarsus of the hind leg and the last three tarsi white. Costa 

 with four large white patches and one or two smaller ones. This species 

 is common in the West Indies, and is found in St. Lucia, Antigua, Gre- 

 nada, Jamaica Cuba, Haitai, and Porto Rico ; it is also recorded from 

 British Guiana, Brazil, and the Argentine. It is an important natural 

 carrier of the parasites of malaria. 



Anopheles (Cellia) aibimanus, Wied. This species is almost in- 

 distinguishable from argyrotarsis, and can only be separated by noting 

 that the last segment of the hind tarsus is entirely black, while, except 

 for the claws, it is white in argyrotarsis. It is common in many parts 

 of the West Indies, and in Brazil. It is a carrier of the parasites of 

 malaria, and can also act as the host of Filalria bancrofti. It breeds in 

 swamps, pools, and in almost any kind of water. 



In spite of the large number of observations which have been made 

 during the course of investigations into the etiology of mosquito-borne 



diseases, it has to be admitted that our knowledge of 

 . ,. . r . . , ,. . ., r Bionomics of the 



the bionomics ot the Anophelma, even in the case ot Anoohelina 



definitely incriminated species, is far from complete.
