ill some specimens the costal cell is nearly clear, but occupied! 

 throughout its entire length with brown spots, some confluent^ 

 especially in the neighbourhood of the stigma, beyond which the- 

 costal part of the «ing is mainly brown or brownish ; the wing 

 is brownish down to the 2ud longitudinal vein ; the whole of the 

 veins in the clear part of the wing bearing a row of minute dark 

 brown spots, which in some examples are considerably fainter 

 than in others ; the brownish colour extending from tiie costal 

 cell is generally somewhat enlarged over the base of the 2nd vein^ 

 and below the stigma, and ihe cross-veins are sometimes suffused 

 with grey. In some individuals the tips of the veins on the 

 posterior margin of the wing are slightly inf uscated, the 7th having 

 often a distinct dark grey spot of moderate size at its tip. 



Length 5-12 millim., without ovipositor. 



Eedescribed from a considerable number of both sexes in the 

 Indian Museum, the Pusa collection and my own, from Calcutta, 

 Darjiling, and other parts of India, Assam, Rangoon, and from 

 Java, The species extends throughout the vhole of the Orient, 

 occurring also in China, Japan, and iVustralia. 



Type presumably in Westerinann's collection in the Vienna 

 Museum. 



In one specimen in the Indian Museum collection there is a 

 supernumerary cross-vein in the 2nd basal cell, a little before 

 the posterior cross-vein. This is probably the most widely 

 distributed species of the family in the East.

 Cladum, Osten Sackeu, Proc. Acad. Nat. Sci. Philad., 18.59, p. 229: 



Genotype, Cladum flavoferrurjinea, Os. Sac; by orio-inal 

 designation. 



Head : eyes separated above by a moderately broad, distinctly 

 convex frons ; nearly contiguous below. Proboscis short ; palpi 

 short, last joint robust. Antennae 16-jointed, just reachino- the 

 root of the wings ; scape with 1st joint subcylindrical, of moderate 

 length, 2nd jouit shorter and broader; flagellar joints subcylindrical, 

 slightly incrassated at base, verticels of moderate length'. Thorax 

 and neck normal. Abdomen with "the upperside of the ultimate 

 segment horny, convex, having a rounded excision between two 

 projecting points on its posterior margin" {Osten Saclcen). The 

 male genital organs consist of a long cylindrical basal joint, 

 the terminal appendages being very small and filiform. The 

 female ovipositor has flattened, rather broad valves. Legs of 

 considerable or of moderate length, pubescent; tibi.-e without 

 spurs; empodia distinct, ungues smooth on the underside. Wings 

 somewhat narrow and rather long, glabrous: veins on apical i^aVt 

 of wing bearing a distinct though short pubescence. Two sub-
