This subfamily and the following, the Rhogadmoi and the Spathiinm^ 

 represent Wesmael's division Oydostomi^ distinguished fi-om the pre- 

 ceding groups l)y having the clypeus emarginate or impressed ante- 

 riorly, and forming, with the mandibles, a semicircular opening. 



The species belonging to this subfamily are easily recognized by 

 the ve7"y short submedian cell in the hind wings and the non-margined 

 occiput, temples, and cheeks. In the SpatldhncB and the RJtogadmcB 

 the submedian cell in the hind wings is never very short and the 

 occiput, the temples, and the cheeks are most frequently' distinctly 

 margined. 



Three tribes or minor groups, have been recognized, distinguished 

 principally by the length of the submedian cell in the front wings. 



table of tribes. 



Submedian cell much sliorter than the median; eyes large, extending clear to the 

 base of the mandibles, the malar space wanting. . .Tribe I. Aphrastobraconini. 



Submedian and median cells equal; eyes not extending to the base of mandibles. 



Tribe II. Bragonini. 



Submedian cell distinctly longer than the median; eyes not extending to base of the 

 mandibles Tribe III. Euurobkaconini. 



Tribe I. APHRASTOBRACONINI. 



This tribe is based upon a species described recently b}' the writer 

 from Ceylon; it di tiers from all other Braconids belonging to the sub- I ( 

 family Braconinw hy the submedian cell being much shorter than the \ 

 median, by the large eyes, and the absence of a malar space: 



Head transverse, the eyes very large, occupying the whole side of the head, the face : * 



and vertex being very narrow; marginal cell extending to tip of the wing, the i 



median cell much longer than the submedian.. (1051) Aphraslolrracon Aahmk^a^. |1 



(Type, Aplirastobracon Jiarripennis Ks\\n'iti'Ai\.) \ \ 



Tribe II. BRAGONINI. *!i 



To this tribe belong the vast majority of the species found in the J 



subfamily BTOConinm; they are separated at a glance from all others I 



b}' having the median and submedian cells of an equal length, the i 



transverse median nervure being distinctly interstitial with the basal i 

 nervure.
