 Journ. Eco. Biol. L, p. 29 (1905). 



Head deep brown, with scattered golden scales ; proboscis 

 and palpi black, the former longer than the body. Thorax rich 

 brown, with brown scales and some scattered dull golden ones, 

 forming two indistinct lateral lines ; scutellum with pale scales. 



Abdomen black, the basal segments with narrow grey apical 

 bands, and all the segments with pale lateral apical spots. Legs

 spots, which are pale. 



9 . Head deep brown, with pale narrow-curved scales and 

 long, black, upright forked scales, sides with small, flat, pale, 

 ochreous scales, and a narrow border of curved grey scales 

 around the eyes. 



Proboscis long and thin, black. Palpi black. Clypeus black. 



Thorax deep brown, clothed with narrow-curved brown scales 

 and some scattered dull golden ones, which form two more or 

 less distinct lines, which pass down to the front of the roots of 

 the wings, and which spread across between the wings and 

 around the bare space in front of the scutellum. On the 

 denuded surface are seen two dark median parallel lines which 

 shine through the scales (when held in some lights, the dark 

 lines become pale silvery grey). Scutellum with narrow-curved 

 pale yellowish scales and black border-bristles, seven of the

 with some small flat white scales. 



Abdomen black, the second and third segments with traces 

 of pale scaled apical borders, and all the segments with grey 

 apical lateral spots ; venter with grey apical bands, the basal 

 segments with many scattered white scales ; border-bristles pale 

 ochreous, the two last segments with many pale hairs over their 

 whole surface. 



Legs deep brown, except the base and most of the under side 

 of the femora ; knee spots yellowish and a trace of a pale spot on 

 the apex of the hind tibiae ; hairs on femora, tibiae and first 

 tarsals pallid ; hind first tarsals about one-fifth longer than the 

 hind tibiae. Ungues all equal and simple, very small. 



Wings with the first sub-marginal cell longer and just a little 

 narrower than the second posterior cell, its base nearer the base 

 of the wing, its stem rather more than one-half its length ; stem
