4. OxYRHACHis SUBJECTA, Walker. 



Oxyrhachis suhjecta, Walker, List Horn. B. M. ii. p. 504 (1851). 

 Smaller than 0. tarandus, the dorsal horns shorter in proportion and 

 less diverging", posterior process more inclined upwards and not serrated 

 beneath. Black with a white pubescence : head transverse, subquadrate, 

 flat, slightly impressed, finely punctured, not much broader than long, a 

 little narrower than the pronotum, truncated and ferruginous in front : 

 pronotum somewhat elevated in front, rather roughly punctured, rising 

 almost vertically from the head with a ferruginous keel or ridge : shoulders 

 of pronotum rounded, not prominent : horns above very broad, prisma- 

 tic, conical, diverging, ascending, hardly curved downwards : posterior 

 side much the shortest of all the sides ; length of the horns rather less 

 than the breadth of the pronotum between them : posterior process 

 mostly ferruginous, reaching well beyond the tip of the abdomen, 

 inclined upwards, and ridged beneath, but not serrated from the middle 

 to the tip : pectus and abdomen whitish pubescent : legs red ; tibise 

 dilated : wings colourless : tegmina tawny, punctured at the base and 

 with a brown spot on the angle of the posterior border ; veins stout, 

 ferruginous, four discoidal areolas (Walker). Body long 6; wings, il| 

 millims. 



Reported from India. 



In 0. tarandus, the pronotum is elevated in front, the posterior pro- 

 cess is ridged and also serrated beneath, the length of the horns is rather 

 more than twice the breadth of the pronotum between them, and there 

 are four discoidal areas : in 0. suhjecta, the posterior process is not ser- 

 rated beneath and the length of the horns is rather less than the breadth 

 of the pronotum between them, otherwise as in 0. tarandus : in 0. uni- 

 color, the pronotum is rather low in front and the length of the horns is 

 as in 0. suhjecta : in 0. rudis, the posterior process is keeled and serrated 

 but there are only three discoidal areas. 



Species of uncertain position. 



5. Membracis fuscata, Fabricius. 



Memhracis fuscata, Fabr., Sysfc. Ehyng. p. 9, (1803) ; Fairmah'e, A. S. E. F. 

 (2 ser.), iv. p. 247, (1846). 



Thorax foliaceous, rounded, fuscous ; streak before the anterior 

 margin and posterior band, white (Fahr.). This species does not seem 

 to have been rediscovered since it was described by Fabricius. Reported 

 from India.
