508 TIPULlDiE. 



rather frail and subject to slight modifications which would render 

 it almost valueless. 



The characters of the first group were : — antennae of 16 joints ; 

 the 2iid submarginal cell never longer than, but generally a very 

 little shorter than the 1st posterior cell ; the prsefurca rather 

 elongate; the palpi rather more elongate than in the next group. 

 This group contained only Amalopis, Hal., and Pedicia, Latr. 

 This second genus is not Oriental, but it contains a widespread 

 European species, F. rivosa, L., which may easily extend to 

 Western or Northern India. 



The second group was characterised by a 13- jointed antenna : 

 the 2nd submarginal cell never being shorter than the 1st posterior 

 cell, but generally a little longer, and the pra^furca very short ; 

 the palpi rather shorter than in the first gi-oup. 



Table of Genera. 



1. Antennre tilamentmis, IG-jointed, joints 



almost inseparable at tip ; 7th longi- 

 tudinal vein much shortened, incurved 



stn)ngly at tip Trichoceka, Mg., p. 508. 



Antennio normally neniatocerous, the 

 exact number of joints being easily 

 counted ; 7th longitudinal vein neither 

 sliovtened nor incurved at tip 2. 



2. Anterior cross-vein connecting the 2nd 



longitudinal vein (either its pncfurca 

 or tlie lower branch) 7iot with the 3rd 

 vein as usual, but with tlie 4th longi- 

 tudinal.* Antenujc of sixteen joints . Amalopis, Hal., p. 513.

Bead : eyes large, convex, pubescent, separated above by a

 side, flattened; two distinct ocelli on each side of a gibbosity just 

 above the antennae Proboscis short ; palpi elongate, especially 

 the last joint, which is narrowed at its middle, sometimes 

 appearing as two joints. Antennae 16-joiuted, longer than the

 the anterior cross- vein, instead of before it as usual. 



t In the two new species referred here to this genus there are fifteen \ery 

 distinct joints.
