3^ (39^ Antennae extremely long; and filiform, the third joint 

 sube(|ual to, or somewhat shorter than, the fourtli, 

 which is more than twelve times as long as wide 

 Tliau>initodryimis. 



39 (38) Antennae without the ahove characters. 



40 (41) Eyes hairy; mandibles tridentate, or with an exces- 



sively minute fourth tooth intercalated between the 

 first and second, abdomen with a short but distinct 



pedicel, reaching^ to apex of hind coxae 



linkocbclcia ( l^Bocchus) 



41 (40) Eyes not hairy; mandibles with four \vell-develope<l 



teeth, abdomen petiolate or subpetiolate. but not pedi 

 cellate. 



42 (43) Fourth tarsal joint of front legs very long and slender, 



twice as long as that part of the fifth which lies be- 

 tween its articulation with the fourth and its true 

 apex, i. e., not less than twice as long as the fiftii 

 excluding its basal process ; stigma narrowly elongate- 

 ovate, the radius long, bent or angulated at about the 

 middle of its length Dcinodryiniis. 



43 (42) Fourth tarsal joint of front legs at most about as long 



as the tifth, excluding its backward basal process, 

 sometimes much shorter still ; stigma more widely 

 ovate, sometimes very large, the radius in many species 

 hardly continued beyond its bend or angulation. 



44 (^45) l^^ourth joint of front tarsi elongate, much longer than 



the third, and articulated to the fifth at, or not far 

 from, the middle of the whole length of this joint, 



including the backward process 



Chcloi^yiiiis {:i=Ncochc!ogyiius) 



45 (44) I-"ourth joint of front tarsi small, and articulated to 



the fifth near to its free extremity, much nearer to this 

 than to the apex of the joint ; or in other words the 

 backward process of the fifth is very short, much less 

 than half the length of the whole joint. 



46 (47) Antennae becoming wider towards the apex; the ]iro- 



podeum l)ounded Ijy a raised line at the truncation, 

 and generally with a more or less defined median area 

 on its posterior face 4ntcon (:=:ProsaiitC()ii ) 



47 (46) .Antennae simply filiform, propodcum without the 



al)Ove characters Puraiitcon. 



48 (i) Tarsi of front legs normal not cliclate \phclopns.
