CHAEACTERISTICS OF LARV.E OF ANOPHELIXA. 137 



There is no proper filament, but a lanceolate ending tapering 

 to a point ; average relation of lancet to leaflet with lancet as 

 20 to 1; maximum, 0"23; minimum, 0"]9. There is not 

 much variation as between individual leaflets. 



The larva of this species comes near to that of funesta, 

 particularly the large variety, and Jacob i. Points of dis- 

 tiuction are that the posterior frontal hairs are relatively 

 longer and finer than those of funesta, in which also is a 

 rudimentary palmate hair of ten or twelve leaflets on the 

 thorax and a well-developed hair on the first abdominal 

 segment, and the palmate hairs are provided with definite 

 filaments, whereas in cinereus there is no hair on the thorax, 

 and the rudimentary hair on the first abdominal segment is 

 smaller. (In one specimen it is very small, indeed.) There is no 

 defined filament. The anterior median frontal hair of jacobi 

 has spicular branches, whereas that of cinereus is smooth. 



Habitat. — The few larvee collected were found in running 

 water — on sea level and at 2200 ft. 



Season . — Perennial. 



Relation to Malaria. — No evidence of anv in Xatal. 



Pyretophorus ar den sis Poicer. 



This species is not described in Theobald's ' Monograph.' 

 'J^he following are distinctive features : 



Palpi thickly clothed with dark bi'own scales, the tip of 

 pale cream, and three narrow bands of the same colour, the 

 second and third being far apart. 



Legs black, all joints banded with pale yellow, the bands 

 being wider in the larger joints and the hind legs than in the 

 smaller joints and fore and mid legs. Coxa and trochanter 

 very pale. Femora, tibia, and metatarsus of all legs brilliantly 

 marked with clearly defined pale yellow or cream spots and 

 incomplete bands, which are appreciable by the naked eye. 



Wings (PI. XXY, fig. d).— The pattern of the markings is 

 sufficiently indicated in the figure. We have not observed 

 nmch variation. The small yellow spot on the first longi-
