the key as a basis. I have in manuscript keys to the genera of 

 these subfamilies, which I hope soon to pubhsh. 



The subfamily divisions here adopted are based upon larval 

 and pupal as well as imaginal characters. 



Males. 



1. Sixth vein ver\' short, seventh bent abruptly forward round 



apex of sixth , FanniincB- 



- Sixth vein complete or incomplete, seventh never bent abruptly 



forw^ard as above .2" 



2. Sixth vein complete; under surface of scutellum usually with 



soft, upright hairs at apex; hind metatarsus wath a strong 

 bristle at base ventrally Antkamyiincs 



- Sixth vein complete or incomplete; under surface of scutellum 



never with hairs at apex; if hind metatarsus has basal 

 bristle the eyes are widely separated and the frons is parallel- 

 sided 3 



3. Centre of pteropleura with a conspicuous group of long hairs; 



eyes widely separated; palpi conspicuously dilated... Lispina; 



- Centre of pteropleura without a conspicuous group of hairs.... 4, 



4. Eyes usually contiguous or subcontiguous, rarely separated. 



by nearly one- third the width of head, if the latter then tjie:^ 

 cruciate frontal bristles are absent; sternopleurals 2 to 4 

 in number, when 3 are present they are not arranged in a 

 nearly equilateral triangle 5 



- Eyes separated by at least the width of head, cruciate frontal 



bristles present only when the sternopleurals are not ar- 

 ranged in a nearly equilateral triangle 6, 



5. Fore femora simple; sternopleural bristles almost invariabh'- 



3 (1:2) or 4 (2:2) in number; if only 2 (1:1) are present the 

 prealar bristle is clearly distinguishable PJiaoniirKZ- 



- Fore femora excavated on under surface near apex and with 



1 or more stout thorns basad of the excavation, or if the- 

 fore femora are simple the prealar bristle is absent and,, 

 as in the previous group, there are only 2 (1:1) sternopleurals- 

 present Hydrotceincs:
