Palpi: in the female the whole of the apical 2/5 of the palpus is 

 smoky white, except for two very narrow black bands which divide 

 it into three. One of these black bands is situated near the apex, aud 

 the other at the next joint. The remainder of the palpus is black, 

 except for a narrow white band at the base of the 2nd joint. There are 

 thus two narrow and two broad bands of each colour. There is also a 

 tuft of white scales on the centre of the basal segment. 



Antennae : have a tuft of white scales on their basal joints. 



Head : has a well marked silver-white crest composed of short 

 scales and long hairs. The forked scales are black. 



Thorax : slate-grey, covered with light coloured hairs. There are 

 ill-defined dorsal and dorso-lateral lines of a darker colour ; and in the 

 wing-plane are two black dots ; there is also a black dot or spot on the 

 scutellum. Along the anterior margin of the thorax there are three 

 tufts of long white scales. 



Pleurae, : much decorated with silver-white patches. 



Halter es : covered with white scales. 



Abdomen : black with many light-coloured, evenly distributed hairs. 



Wings : with the 2nd transverse vein opposite the 3rd, the 4th

 the apex of wings and at the junctions of the longitudinals : otherwise 

 it is black.

Of the new species 



This is a " clear >1 winged species. It was first found 



Tlf oh Id ' ky ^ r ' ^' ^* Aitken on the Goa frontier. A few 



isolated specimens were bred from May onwards. 

 It was not until December that its larva was isolated. Larva? were 

 only found in pools situated in thick " evergreen " jungle. 



is small, compact, and of a brick-red colour, is 3 mm. in 



length and very closely resembles A. fiuviatilis larva 



except that, unlike the latter, it prefers living in the 



deeper water in the centre of the breeding vessel. Bristles of larva 



are figured in Plate, figs. 5a and 5d. 



Frontal bristles, median : thick and bifurcated at extremity, the ends 

 curve downwards, forming a regular pitchfork. 

 Frontal bristles, angular: short, simple. 

 Buccal hair : covered with long, simple branches, true to usual type.
