The descriptions of the species follow in the order in which they 

 appear in the above table merely for the sake of convenience. 



The genus is evidently an extensive one in the East and many 

 more species must remain to be discovered, so that any attempt at 

 an arrangement according to affinities would be premature. 



378. Eriocera ctenophoroides, Edw. 



Eriocera ctenophoroides, Edwards, Ann. Mag. Nat. Hist. (8) viii, 

 p. 64 (July 1911). 



" Head black, with a black pubescence. Antennae 8-jointed in 

 both sexes, but the last four joints indistinctly separated ; scape 

 dark fuscous, flagellum ochreous brown. Palpi blackish. Thorax 

 entirely brick-red, velvety in appearance, except for a line round 

 and just below the mesonotum, which is shining and translucent. 

 Post-alar calli and protuberance below root of wing with tufts of 

 black hairs. Abdomen deep black, except the 1st segment and the 

 ovipositor which are reddish ; for the most part brilliantly shining, 

 but there are apical velvety bands on segments 2 to 6, these are 

 broadest on segments 2 to 4, and broader in the female than in 

 the male. Venter entirely dull. The abdomen is much broader 

 in the middle. Leys uniformly dark brown, except for the red 

 coxa? ; densely covered with somewhat accumbent black pubes- 

 cence ; stouter and shorter than usual in Eriocera, giving the 

 insect a very CtenopJiora-like appearance, which is heightened by 

 the form and colour of the abdomen. Wings dark brown, lighter 

 towards the anal margin and in the centre of some of the cells ; 

 a small, long and narrow, more or less crescent-shaped spot in 

 the outer marginal cell, a very small triangular spot in the 1st 

 submarginal, and a large semicircular spot in the outer portion of 

 the 2nd submarginal and 1st posterior, white, all reaching the 

 wing-margin. 



" There are some very interesting features in the neuration ; 

 the uppermost of the three veins proceeding from the discal cell 

 is curved downwards, in the type male to such an extent that 

 the 2nd posterior cell is completely closed at its apex ; in the type 

 female the small cross-vein is absent, the 1st basal cell being 

 open. I have not met with either of these variations in any other 

 Tipulid. Halteres brown, knob somewhat darker, stalk hairy. 



"Variety. One female has the thorax entirely velvet-black and 

 the legs darker.
