 kindly contributed an abstract froni his unpublished MS. 



Our species of this interestinj; family have been very little studied, 

 as will be seen by the .small nuini)er of unstarred t;enera in the fbl- 

 lowinj; tables. The undescribed nuiti-rial in the collection of the 

 American Entomological Society is large, and contains representa- 

 tives of many genera characterized below, and of which no s])ecies 

 have yet been described as occurring witliin our fauna. 



The familv is divided into six divisions in the following manner;

CYCLO.STOMI. 

 ("Ivpeus not so eniarfiinatc, fitting closely to the mandibles. 



Abdomen above witluait .sutures, segments 1-3 forniin}; a .solid shield, or 



with two .superficial sutures at most, but still exartieulate. 



ci{Ypt<kia.stkp:s. 



Abdomen showing the usual siuurcs. 



.Second snbmarginal cell minute, often imperfect ARKOLAHII. 



Second sui. marginal cell large, 4-angular or wanting POLYMOUl'HI. 



Mandibles with their tips turned outwards, not in contact EXOI"M)XTKS. 



Articulation between second and tliird abdominal segments, as well as the other.s. 

 flexible, allowing the at)domen to be curved under the thorax.

Div. I.-CYCLOSTO.MI. 



Occiput not margined, or only faintly .so at the sides 2. 



Occiput margined, distinct from the vertex .3. 



2.— Transverse medial nervure uniting or interstitial with the basal nervure, the 

 median and subraedian cells therefore of sjime length on the externo- 



medial nervure Braconinee. 



Transverse medial nervure received by the first di.scoidal cell, the median 

 cell therefore shorter than the submedian cell on the externo-medial 

 nervure Exothecinse. 



3.— Abdomen petiolate Spathiinse. 



Abdomen sessile or subse.ssile 4.
