KHAMPHIDIINI. 415 



marginal cross-vein is quite distinct and meets the 1st longitudinal 

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

 turning down into the 2nd vein as in the 



Section BHAMPHIDIINL 



Proboscis normally conspicuously produced,* sometimes short 

 (Atarba). Antennae usually 16-jointed, in one genus (Toxorhina) 

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

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

 the Oriental genera except Orimarga. The auxiliary vein ends 

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

 and Orimarga, but barely apparent in Gymnastes. The marginal 

 cross-vein is present in Teucholabis, Gymnasles, and Orimarga, 

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

 Antocha ; absent in Atarba. Toxorhina, and Rhamphidia. Posterior 

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

 Orimarga placed very far back making the 4th posterior cell as long 

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



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

 by Osten Sacken amongst his LIMXOBIKA ANOMALA, which were 

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

 other divisions of the family.

Discal cell present 4. Tp. 423. 



4. No submargiual cross-vein ATARBA, Os. Sac.,

though sometimes faint 5. 



5. Submarginal cell as long as or very little 



longer than the 1st pasterior cell 6. 



Submarginal cell much longer than 1st 



posterior cell ANTOCHA, Os. Sac., 



6. The 2nd posterior cell rectangular (approxi- [p. 425. 



mately) at base ; hind femora not clubbed. TEUCHOLABIS, Os. Sac., 

 The 2nd posterior cell pointed at base ; hind [p. 427. 



femora distinctly clubbed towards tip GYMNASTES, gen. nov., 



[p. 432. 



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

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

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

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