146 APPENDIX. MEMBBACID^. 



Family MEMBRACID.E. (Vol. IV, p. 1.) 



A considerable addition to tlie number of genera and species 

 enumerated and described in Volume IV is made in the following 

 pages, and there can be no doubt that there is still much more 

 to be seen and done in the description and enumeration of 

 Indian Membracidse.. 



Genus OXYRHACHIS. (Vol. lY, p. 3.) 



OXTRHACHIS TAKANDUS. (Vol. IV, p. 4.) 



Attached to a specimen received from Rajshahi, E. Bengal, is 

 a label "with larvae on twig, attended by the ant Camponotus 

 comjyressus, Fabr." 



3383. Oxyrhachis formidabilis, sp. n. 



Dark fuscous or black, thickly coai'sely punctate, a strong 

 central longitudinal castaneous carination extending through 

 pronotal front to a|)e5 of posterior pronotal process, about apical 

 half of this process darker, or black ; legs brownish ochraceous, the 

 femora (excluding apices) more or less black; tegmina dull hyaline, 

 the base more or less dark ferruginous, the veins and extreme 

 costal margin ferruginous-brown ; lateral pronotal processes long 

 and recurved, distinctly elevated, their apices subacute, strongly 

 tricarinate ; posterior process long, upcurved, thus barely ex- 

 tending beyond tegminal apices, beneath laminately anipliate and 

 obscurely seriate. 



Length 7 to 9 ; breadth lat. pronot. process. 5 to 5^ millini. 



Hal). Dehra Dun, Suraj Bagli (on grass). Salem Dt., Athur- 

 kuppam. 



Allied to 0. farandus, Fabr. (vol. iv, p. 4), but differing by the 

 longer upturned lateral pronotal processes. 



Oxyrhachis rufescexs to replace 0. rudis. (Vol. IV, p. o.) 



Oxyrhachis rufescens, Walk. List Horn, ii, p. 506 (185]). 

 Oxyrhachis rudis, Walk. List Horn, ii, p. 509 (1851). 



The unique type of Walker's 0. rufescens was and is an un- 

 localized specimen. Now that I have seen a larger series of his 

 0. nulls, I feel no doubt that they are one and the same species, 

 and rufescens having been described on an earlier page of his list, 

 that name must take precedence. 



Add: Rab. South India; Mysore State {T. V. Cam/'hell). 

 E. Bengal; Kajshahi (Zool. Gardens, Alipore — on Cassia stima- 

 trana). Satara Distr. ; Medha, Yenna Valley (F. H. Gravely).
