HEMIPTERA HOMOPTERA OF CErLOK. 165 



castaneous, coxae black, tips of tibiae and tarsi inclining to blackish. 

 Tegraina dark chestnut, broadly black at the base and for two 

 thirds of the length of the costa, and the nervures mostly black, 

 except towards the extremities. 



Allied to G. suhstitutus, "Walker.

Another specimen, which I can hardly consider distinct, has 

 shorter and thicker horns, and the tomentum is white rather than 

 golden. It is covered beneath with a white waxy exudation,, as 

 is frequently the case in these insects. The horn is also more 

 depressed. 



*CElirTEOTUS DECIPIENS, Sp. n. 



Long. Corp. cum tegm. 6 millim. ; exp. corn. 3 millim. 



Black, punctuation rather finer than in O. Jlavipes ; lateral 

 thoracic horns acute, slightly recurved, moderately long and 

 slender ; central horn raised at the base and then curved back- 

 wards, as in C. leucaspis. Walk., nearly to the end of the tegmina, 

 which are yellowish hyaline ; pectus in the specimen described 

 with waxy eflSorescence, which is continued round the sides of 

 the pronotum and the base of the scutellum ; tegmina yellowish 

 hyaline, the nervures nearly concolorous, base black, and the 

 costa to the tip rather broadly black ; coxae black ; legs rufo-tes- 

 taceous ; hind legs pale testaceous. 



Nearest to C. leucaspis, from which it differs, inter alia, in the 

 colour of the legs and in the white border of the pronotum &c. 

 This is one of Walker's MS. species, which he has ticketed, and 

 which I think it well to take the present opportunity of putting 

 on permanent record. 



Ceylon ; particular locality not recorded. 



*tCENTKOTTJS ELAVIPES, Sp. n. 



Long. Corp. cum tegm. 7 millim. ; exp. corn. 4 millim. 



Closely allied to C. atricoxis, of which it may be a variety. The 

 structure is nearly the same, but the tomentum is white, not 

 golden ; the legs are testaceous, shading into reddish brown on 

 the tips of the tibiae and the tarsi, and the tegmina are lighter, 

 the nervures, except those on the black portion, being cas- 

 taneous. The pectus and pleura are covered with a white waxy 

 exudation.
