II. EXOTHECIDES. 



Pobrachial transverse nervure evectecl. Recurrent nervnre 

 rejected (except in Bathystomus). Suturiform articulation obso- 

 lete, segments 2 — 3 being connate (except in Phanomerls). 



This division is formed of portions of the genera 

 Colastes, Hal., and Exothecus, Wesm., the remaining 

 species of which are are associated by Forster with the 

 Rhyssalidcs. The character by which the Exothecides 

 are separated from the Braconides is easy to be seen ; in 

 the former the pobrachial transverse nervure is evected, 

 in the latter, interstitial. From the Rhyssalides they 

 are less obviously distinguished by the absence of a 

 well-marked occipital margin, though in Phanomeris, 

 according to Haliday, the occiput is finely margined. 

 The species are few in number, only five being known to 

 us as inhabiting England, all described by Haliday 

 under Colastes ; but according to the Forsterian system 

 they now belong to four distinct genera.

Suturiform articulation distinct, sometimes crenate. Occiput 

 scarcely, or not at all margined. Eadius originating from the 

 stigma somewhat before tlie middle. Pobrachial areolet of the 

 hind wings less than one-half the length of the prsebrachial. Meso- 

 thoracic sutures very fine, impunctate. Two species: — 



Segment 2 aciculated at the base ; wings hyaline . . 1. cateiiator, Hal.
