424 TIPULIDJ2. 



Leys long, slender, apparently glabrous, microscopically pubescent ; 

 tibiae not spurred at tip ; ernpodia distinct. Winys somewhat 

 narrow and elongate.' with one submarginal and four posterior 

 cells, and an open discal cell coalescing with the 2nd posterior 

 cell ; posterior cross-vein near the middle of the winy ; the 

 auxiliary vein ending in the costa a little before the inner end of 

 the submarginal cell, and some distance beyond the origin of the 

 2nd longitudinal vein ; the tip of this vein (auxiliary) thickened, 

 running obliquely into the costa and strengthening it ; the 1st 

 longitudinal ending some distance beyond the tip of the auxiliary, 

 joining the costa some little distance before the tip of the wing ; 

 the 2nd vein beginning about the middle of the wing, quitting the 

 1st at a sharp angle, thence turning suddenly and running nearly 

 straight to the margin, the prsefurca forming nearly or quite half 

 the length of the vein ; marginal cross-vein just beyond the 

 middle of the marginal cell ; the 3rd vein starting at an angle, 

 running nearly parallel to the 2nd vein ; the anterior cross-vein 

 situated soon after the origin of the 3rd vein, a little behind the 

 marginal cross-vein, joining the upper branch of the 4th vein soon 

 after its origin; the lower branch of the 4th vein forked, the 

 discal cell open, coalescing with the 2nd posterior cell ; posterior 

 cross-vein placed near the middle of the wing just beyond thn 

 origin of the 3rd vein, thus much shortening the 2nd basal cell 

 and correspondingly greatly lengthening the oth posterior cell, 

 which is twice as long as the 2nd posterior and nearly three times 

 as long as the 3rd ; the 5th, 6th, and 7th veins nearly straight, 

 the two former closely approximate for the first third of their 

 length. 



Range. Europe, Australia, and India. 



Orimarga has affinities with Dicranoptycha, from which it is 

 easily distinguished by the unusual position of the posterior cross- 

 vein and the absence of the discal cell, which in Dicranoptycha is 

 present. Osten Sacken sees affinities with Toxorhina in the 

 oblong thorax, which is narrow when seen from above ; in the 

 somewhat elongate neck ; and in the extra development of the 

 mesosternum. 



308. Orimarga peregrma, sp. nov. (PI. VIII, fig. 11.) 



c? . Head : eyes rather wide apart. Proboscis bright reddish 

 brown on basal half, dark brown on apical half; palpi black. 

 Antennre with 1st joint of scape long, bright reddish brown, 2nd 

 large, rounded, blackish ; flagellum yellowish brown, with a little 

 light grey pubescence. Thorax yellowish, dorsum mainly brownish, 

 the colour more or less in the form of the usual broad median 

 dorsal anterior stripe, contiguous, or nearly so, with the shorter 

 outer broader stripes, which latter are continued beyond the
