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 2nd 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, P. 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 prsefurca very short; 

 the palpi rather shorter than in the first group. 



Table of Genera. 



1. Antennas filamentous, 16-jointed, joints 



almost inseparable at tip ; 7th longi- 

 tudinal vein much shortened, incurved 



strongly at tip TRICHOCERA, Mg., p. 508. 



Antennae normally nematocerous, the 

 exact number of joints being easily 

 counted j 7th longitudinal vein neither 

 shortened nor incurved at tip 2. 



2. Anterior cross-vein connecting the 2nd 



longitudinal vein (either its prsefurca 

 or the lower branch) not with the 3rd 

 vein as usual, but with the 4th longi- 

 tudinal.* Antennae of sixteen joints . AMALOPIS, Hal., p. 513.

 4th longitudinal veins as usual 3. [p. 517.

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

 broad or very broad Irons, contiguous or subcontiguous on under- 

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

 above the antennas. Proboscis short ; palpi elongate, especially 

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

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



* In other words, the 3rd longitudinal vein emerges from the 2nd beyond 

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



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

 distinct joints.
