OF WASHINGTON. 165 



This species was first sent me by Prof. Forbes, who reared it 

 from the larva of Hyphantia cunea. Dr. Dimmock reports 

 having bred it from an undetermined noctuid larva feeding on 

 Apple leaves. 



As I have described above two species of Microgasterines in 

 genera not yet characterized, I give here my table of the genera 

 of the subfamily Microgasterince, taken from my forthcoming 

 Monograph on the North American Braconidse. 



TABLE OF GENERA. 



Marginal cell incomplete or wholly wanting 2 



Marginal cell completely closed. 



Front wings with two submarginal cells; antennae i6-jointed. 



(i) Ecclites Forst. 



2. Marginal cell for the most part entirely absent with only the first 



abscissa of radius present 3 



Marginal cell not entirely wanting with the radius present but 

 shortened. 



Antennae 2o-jointed ; metanotum not strongly areolated, the 

 radius not geniculate ; hind part of cubitus emerging from the 



first discoidal cell (2) Acoelius Hal. 



Antennae 2i-jointed; metanotum strongly areolated, the radius 

 geniculate; hind part of cubitus emerging from the first dis 

 coidal cell (3) Dirrhope Forst. 



Antennae i3-i4-jointed in 9> i cT i4-i6-jointed ; metanotum 

 not areolated ; radius geniculate, the areolet incomplete but 

 in position quadrate; hind part of cubitus interstitial with the 



fore part , (4) Elasmosoma Ruthe. 



? = Neoneurus Hal. 



3. Front wings with 3 submarginal cells, although the second or the 



areolet is sometimes open behind and therefore confluent with the 



third....! 4 



Front wings without or at the most with only 2 submarginal cells, the 

 areolet not defined. 



Front wings without submarginal cells, the first and second sub- 

 marginal cells and the first and second discoidal cells confluent ; 

 mesonotum with a large fovea in front of the scutellum ; an 

 tennae 2i-jointed; hind coxae very long, cylindrical. 



(5) Ccelothorax Ashm., n. g. 



Front wings with 2 submarginal cells, the discoidal cells distinct, 

 separated; mesonotum normal; antennae 14-jointed; hind 

 wings without a radius or cubitus (6) Mirax Hal. 



4. Antennae i8-jointed. 



Second submarginal cell or the areolet completely closed 6 



Second submarginal cell open behind and confluent with the 

 third.
