Phis subfamih" is allied to the Mac7'ocent7'i7ice, but is easil}^ separated 

 l)y the larger, more quadrate head, the temples being broad, not 

 narrow or flat, by the shape of the abdomen, and by the short, stout, 

 tibial spurs, which are quite characteristic and ver}" distinct from 

 those found in the subfamily Macroceiitrinw. 



In it is included the singular genus Ceiiocodius Haliday, at one time 

 classified with the Evaniidcv, on account of the abdomen being attached 

 high up on the posterior truncature of the metathorax, as in Evania. 

 It is, however, a true Braconid in all other characters, venation of 

 front and hind wings, and in its economy. 



Two tribes are recognized, as follows: 



table of tribes. 



Head with a deep frontal excavation above the insertion of the antenna?, the front 

 ocellus placed in the excavation; abdomen most frequently longer than the head 

 and thorax united, rarely shorter; posterior femora usually somewhat incras- 

 sated and often armed with a tooth, or teeth, beneath Tribe I. Helconini. 



Head at the most with a shallow frontal excavation, the front ocelli not placed in 

 the depression; abdomen not as long as the head and thorax united, oblong-oval 

 or ovate; posterior femora rarely much incrassated, and always simple, unarmed. 



Tribe II. Diospilini. 



Tribe I. HELCONINI. 



This tribe represents Forster's family Ilelconoidce^ or Marshall's 

 tribe Ilelcontides, and is readily distinguished by the charactei-s 

 pointed out above, the frontal excavation, the position of the front 

 ocellus being characteristic.
