Family BRACONIDAE i3o 



Compiled by C. F. W. Muesebeck 



New York specimens of all the species of Braconidae in the following list have 

 not yet been obtained, or at least have not yet been identified ; but on the basis of 

 their known general distribution and hosts, they must certainly occur in the State, 

 and for that reason are included.i^i Many of the subfamilies are still in an extremely 

 unsatisfactory condition from a taxonomic standpoint. This is true particularly of 

 Alysiinae, Blacinae, Sigalphinae, Braconinae, Macrocentrinae, Hormiinae, and Aleio- 

 dinae. Revision of these groups, and the more thorough working of material already 

 in museum collections, will certainly reveal a much larger braconid fauna in the 

 State of New York. Practically all the species of this family, with the exception 

 of certain Alysiinae, are primary parasites, and many of them are very important 

 agents in the natural control of injurious insects. 



SUBFAMILY COENOCOELIINAE 



This group has sometimes been held as a distinct family because of the unusual 

 attachment of the abdomen far above the level of the posterior coxae, in which 

 respect it somewhat resembles the Evaniidae. But the wing venation and general 

 structure, as well as the habits and manner of development of the various species, 

 are typically braconid. It is nearest the Helconinae. 



1^° At the suggestion .of the editors, Mr. Muesebeck has retained the sequence of subfamilies 

 developed by Szepligeti in Genera Insectorum, vol. 22, Hymenoptera, Fam. Braconidae, 1904. 



^^^ Although in other groups species not actually recorded from the State have not been listed, 

 in view of the great pains taken by Mr. Muesebeck in preparing the list of this family, and his 

 feeling, shared by ourselves, that the omission of such species would greatly ci:rtail the value of 

 the list, they have been included but placed in brackets and set in italics. As so much of the 

 literature dealing with our species of Braconidae has been published subsequent to any catalog, 

 Mr. Muesebeck has kindly included the reference to the oi-iginal description of each species.— Editors.
