mar"iiuil cross-vein is quite distinct and meets tlie Ist longitudinal 

 in a'^curve, the appearance is given of the 1 st longitudinal distinctly 

 turning down into the 2nd vein as in the TiPULixJi. 



Section UHAMPIIIDIINI. 



Proboscis normally conspicuously produced,* sometimes short 

 {Atarha). Antennae usually KJ-jointed, in one genus (ToxorJiina) 

 only 12-jointed. The wings with one submarginal cell (none in 

 ToxorUna) and four posterior cells ; the discal cell closed in all 

 the Oriental genera except Orimarrja. The auxiliary veni ends 

 generally about the middle of the wing; it is longer in Antocha 

 and Orimarrja, but barely apparent in Gymnastes. The marguial 

 cross-vein is jn-escut in Teucholahis, Gymnastes, and Orimarga, 

 being placed about the middle of the marginal cell ; it is feeble in 

 Autocha ; absent in Atarba, ToxorJiiua, and llhamphidia. Posterior 

 cross-vein situated before the discal cell or before its middle ; in 

 Orimarr/a placed very far back making the 4th posterior cell as long 

 as the 2nd basal celf. The rest of the venation normally typical. 



This is somewhat of a heterogeneous group still, and was classed 

 by Osten Sacken amongst his Limxouina axomala, which were 

 admittedly the genera that would not naturally lit into any of the 

 other divisions of the family.

* In one genus, Elephant om//ia, Os. Sac, which is Oriental but not Indian, 

 the proboscis' is enormouslv prolonged to a length much greater than that of 

 the body. It may be noted here that in this genus the antenna; are apparently 

 15-jointed, owing to the coalescence of the two basal joints of the flagelluin.
