OXYKH.VCIIIS. o 



This species in the Madras .District, was found by Mr. E. P. 

 Stebbiug on Acacia slamea and A. arahica and on Casuarina. In 

 Mr. Buckton's collection tbere is a Madras specimen labelled 

 Centrotus ^-'m/zo (type), of which I can find no published description, 

 Init the species may have been distributed under tliat name and 

 therefore requires mention. 



Prof. Poulton has sent me examples for comparison of the 

 species described by Buekton as Polocentrus nifus ; his P. neuter 

 was described from my own collection. Both his figures must be 

 ignored. The species figured by Buekton (Monogr. Membrac. 

 t.xlix, f . 3, rt, f>) as O.vi/rJuicMs tarandvs is the S. African Xipliistes 

 farcicornis. Germ., his cotypes are now in my collection.

" jN'early allied to 0. tamndus but is smaller ; the dorsal horns 

 are shorter in proportion and less diverging; the hind appendage 

 is more inclined upward and not serrated beneath. Black, clothed 

 with whitish down ; head transverse, sub(]uadrate, flat, slightly 

 impressed, finely punctured, not much broader than long, a little 

 narrower than the fore-chest between the shoulders, truncated and 

 ferruginous in front ; fore-chest rather high in front, rather 

 roughly punctured, rising almost vertically from the head, with a 

 ferruginous ridge ; shoulders rounded, not prominent ; horns 

 above very broad, prismatic, conical, diverging, ascending, hardly 

 curved, downward ; hind side much shorter than either of the 

 other sides : lens-th of the horns rather less than the breadth of the 

 chest between them ; hind appendage mostly ferruginous, extend- 

 ing very far beyond the tip of the abdomen, inclined upward and 

 keeled beneath but not serrated from the middle to the tip ; breast 

 and abdomen clothed with white down ; legs red ; shanks widened ; 

 wings colourless ; fore-wings tawny and punctured at the base, with 

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

 ferruginous ; four discoidal areolets." ( M^alker.) 



" Length of the body 3 ; of the wings 54 lines." 



Hah. " East Indies." 



The unique type of this species is now in a most mutilated con- 

 dition, the " dorsal horns " being quite destroyed. According to the 

 description, it differs from the preceding species by the non-serrate 

 under surface of the posterior process.

Ferruginous-brown, a central pale carinate longitudinal Hue 

 traversing the pronotum and the posterior process ; tegmina very
