Longicprnia Malayana. 11 



thocinus and Alphas, distinguished from the former (jinter alia) by 

 the absence of the lengthened ovipositor in the female, and from 

 the latter in the greater length of the scape : in habit it is very 

 distinct. 



Acanista Alphoides. (PI. I. fig. 3.) 



A, leviter grisescente-pubescens, albo-varia ; antennis obscure 



annulatis. 

 Hab.—My?.o\. 



Thinly pubescent, dark greyish shading into white on each side 

 of the prothorax and on the posterior half of the elytra, where 

 also there is a pure wliite mark bent at an acute angle on each 

 side towards the apex. Head narrower than the prothorax, 

 slightly dilated below the eyes, the lip and epistome narrow ; 

 prothorax transverse, strongly spined at the sides, the anterior 

 and posterior borders of equal breadth ; scutellum rounded behind ; 

 elytra broader than the prothorax, depressed in the middle or 

 somewhat concave, coarsely punctured, a line of small spines near 

 the suture and several smaller ones at the shoulder, one also 

 rather larger than the rest between the shoulder and scutellum, 

 the apex truncate at the suture, then broadly emarginate ex- 

 ternally, and ending in a long acute spine ; body beneath with a 

 pale greyish pubescence ; legs obscurely annulated with greyish 

 and white ; antennse about three and a half times as long as the 

 body, the third and fourth joints with a very small spine at the 

 apex. 



Length 7 lines. 



Driopea. 

 Driopea, Pascoe, Trans. Ent. Soc. ser. 2, iv. 243. 

 Caput antice subquadratum, fronte convexo. Anteimce elongatas, 

 ciliatse, scapo subcylindrico, articulo secundo brevi, casteris 

 subaequalibus. Prothorax Isevis, subrotundatus, dente minuto 

 lateral! instructus, aliquando muticus. Elytra elongato- 

 ovata, regularia, apice truncata vel emarginata. Pedes postici 

 elongati, femoribus vix clavatis ; tarsorum intermediorum et 

 posticorum articulus basalis elongatus. 



Of the more generally known genera of this sub-family, this 

 genus is, perhaps, most nearly allied to Leioptts, but from which it 

 is distinguished by its elongate posterior legs, truncate elytra, 

 prothorax, and other characters. In coloration it resembles, like 

 many more Indian genera, some of the species of Clytas.
