426 TIPULID.E. 



distinct. Abdomen normal. Genitalia of male consisting of the usual 

 claspers, the 2nd claw-like horay joint very small. Ler/s rather 

 shorter than usual, moderately stout ; tibiie without spurs at the 

 tip ; empodia indistinct, ungues very small with teeth on the under- 

 side at the base. Wim/s fairly broad, iridescent, anal lobe of wing 

 approximately I'ectangular. One submarginal cell, a discal cell, 

 and four posterior cells ; auxiliary vein approximating very closely 

 to the 1st longitudinal vein, not easily distinguished, ultimately 

 coalescing with it, the united veins gradually merging in the costa, 

 which is thickened at and beyond their junction, this taking place 

 near the tip of the wing; subcostal cross-vein absent; marginal 

 cross-vein feeble ; the 2nd longitudinal vein not forked, beginning 

 much before the middle of the wing at a very acute angle, and at 

 the origin of the 3rd vein, it is, in some species, angled again, the 

 remaining part being as long as the prsefurca ; the 3rd vein as 

 long as, or a little longer than the apical half of the 2nd vein, 

 gently bisinuate ; anterior cross-vein placed at the middle of the 

 discal cell or at its proximal upper corner, opposite the marginal 

 ci'oss-vein ; discal cell approximately rhomboidal or of irregular 

 shape (pentagonal in opalizans, Os. Sac, of North America), a 

 little less in length than the 2nd and 3rd posterior cells, though 

 this proportion probably varies with the species ; posterior cross- 

 vein situated at the base of or distinctly before the base of the 

 discal cell; the 5th vein absolutely straight, the 6th and 7th 

 practically so. Stigma elongate, not very sharply defined. The 

 wings are said to have a milky white tinge, but this is not very 

 apparent in the two Oriental species at present known. 



Range. India, Europe, Canada, United States. 



The two Indian species may be separated thus : — 



Posterior cross-vein distinctly anterior to 



discal cell ; thorax with three stripes .... indica, sp. n. 



Posterior cross-vein at basal corner of discal 

 cell ; thorax with one median stripe only, nnilineata, sp. n. 



308. Antocha indica, sp. nov. (PL VIII, fig, 12.) 



S 2 . Head yellowish, occiput dark grey ; proboscis and palpi 

 brown with a few In^istly hairs ; eyes \\e\\ separated. Antennae 

 blackish, rather thickly pale pubescent, joints oval, distinct; 1st 

 scapal joint yellowish, 2nd very short, black. Thorax yellowish ; 

 the usual three dark stripes nearly contiguous ; sides of thorax 

 yellowish ; scutellum and metanotnm brownish grey, lightly 

 dusted. Abdomen brownish yellow, one example (the type) 

 showing a dark line towards each side. Genitalia of moderate 

 size, yellow. Legs yellow or brownish yellow. Wings colourless; 

 veins yellowish, costa yellow, no stigma ; marginal cross-vein 

 invisible in one example; anterior cross-vein just before middle of
