354 TIPULID.'E. 



Legs excessively loug and slender, especially the tarsi. Apical 

 spurs of tibife ver}^ minute, hardly visible amongst the hairs on 

 the tip, raore distinct on the hind legs. Wings with no discal 

 cell ; one marginal, one subniarginal, and five posterior cells. 

 Auxiliary vein ending some distance beyond the middle of the 

 wing, turning at its tip into the 1st longitudinal vein, which, 

 ending a little beyond the auxiliary, itself turns into the 2nd vein 

 before the middle of that vein, which latter is very short, strongly 

 bisinuate, originating at two-thirds the length of the wing ; the 

 discal cross-vein short ; no anterior branch to the 2nd vein ; the 

 3rd vein almost of the same length and shape as the second; the 

 anterior cross-vein very short ; the 4th vein forking just beyond 

 the posterior cross-vein, the anterior branch forking just before 

 its middle, the upper prong again forking about its middle, the 

 veinlets nearly parallel, thus making the 2nd posterior cell petio- 

 late ; the lower prong simple, strongly bisinuate ; the posterior 

 branch of the 4th vein gently bisinuate, the posterior cross-vein 

 very oblique ; the 5th, 6th, and 7th veins nearly straight.* The 

 " obliterative streak " is absent. 



254. Dolichopeza orientalis, sp. nov. (PI. V, fig. 19.) 



cJ 5 . Head : vertex and frons rather bright light brownish 

 yellow (darker yellow in female) ; frons one-fourth to one-third 

 the width of the head ; back and underside of head pale yellowish, 

 with short black hairs. Eyes wide apart below, with a small black 

 spot at their inner angles. Proboscis short, thick, yellowish ; 

 palpi brown or blackish, the last joint narrowed at its base, clubbed 

 towards its tip. Antennal scape pale or orange yellowish, 2nd 

 joint short ; flagellum of thirteen very elongate, brownish yellow, 

 cylindrical joints, the 1st one and a half times as long as the 2nd, 

 the rest gradually diminishing in length, the last very short, all 

 with close microscopic pubescence below and some longer scattered 

 hairs on the upperside. Thorax wholly pale yellowish, except 

 three short and not very distinct x-eddish brown narrow stripes on 

 the dorsum, in the usual position, the outer ones sometimes barely 

 visible ; two brownish irregularly shaped spots behind the suture. 

 Scutellum, metanotum, and sides of thorax concolorous. Abdomen 

 variable, reddish or yellowish brown, with very few pale hairs ; 

 posterior margins of segments more or less black, the whole of the 

 7th and 8th segments black, sometimes the 4th, 5th, and 6th 

 segments also. Genitalia large, globular, but mainly concealed, 

 black ; two pairs of slender, yellow, palp-like organs, the upper 

 pair the longer and more slender, closely pubescent ; there are 

 three pairs of inner organs, one pair consisting of a slender basal 



* Dolichoprza is easily recoguised by its wings ; the absence of the discal 

 cell, the simple 2nd vein, the twice forked anterior branch of the 4th and the 

 bisinuate nature of many of the veins form a venation quite distinct from all 

 else in the Tipulid^.
