coinciding with the second in the said series of five ; here, 

 again, the last is weak and very light in colour, and, generally 

 speaking, those on the lighter areas of the wing are less 

 strong and lighter. Costal series few and irregular.

Heliothrips bicinctus, sp. n. 



$ . — This species comes very near to B. femoralis, Reut., 

 with which it may be mixed in collections. It is not so deep 

 in coloration, and may be sharply separated by the coloration 

 of the legs and wings as follows : — 



Fore-wings brown excepting - for a light area near 

 base before distal fourth and at extreme tip, 

 these areas being very short and ill-defined. 

 All tibiae, tarsi, and fore-femora yellow .... H. femoralis, Rent. 



Fore-wings light-coloured, with two dark brown 

 bands, the first (occupying about one-eighth 

 the length of the wing) starting near the be- 

 ginning of the secoud fourth and the other 

 (occupying about one-seventh the length of 

 the wing) just before tip. Hind-tibipe wholly 

 yellow ; fore-femora and the fore and more 

 especially the intermediate tibiae more or less 

 deeply shaded with grey to grey-brown .... H. bicinctus, sp, n. 



The antenna? are incomplete in the four specimens now 

 before ine, and until I make further preparations I am not 

 prepared to give a fuller description. The fore-wings are 

 obviously more linear and slender than in H. femoralis } and 

 the spines of the costa, fore-vein (from union with hind-vein), 

 and hind-vein are respectively as follows : — 20 to 21 ; 14 and 

 13 to 14. 



In the African example the wing-spines appear to be 

 stronger, whilst the intermediate tibia is very dark brown 

 excepting basally and at apex.
