Stephanid^. 



The position of this family remains undetermined, as it 

 appears to form a transition between the Ichneumonidse and 

 Evaniidae, with some leanings towards the Braconidse. Different 

 authors have taken very varied views as to its affinities. Cresson 

 includes only Stephanus and the synonymous Megischus ; Cameron 

 adds Monomachus ; while Ashmead unites Stephanies and 

 Megalyra. Even Schletterer, the monographer of the family, 

 declined to express any decided opinion. Some authors unite 

 Stephanus and Btenophasmtis as members of this family, though 

 Ashmead places the latter next to Doryctes, and they are now 

 usually considered to be Braeonidae. The two may be easily 

 distinguished : — 



Antennae 30-40-jointed, shorter than body ; anterior ocellus 

 surrounded by five frontal tvibercles ; mandibles recurved, 

 parrot-like ; mesonotum not sulcate : scutellum tripartite ; 

 posterior femora armed with two or three large teeth 

 beneath. Fore wing with one cubital cell, hind wing with- 

 out cell, or with one only; abdomen convex beneath. 



Stephanid^. 



Antennae with about 70 joints, longer than body ; frontal 

 tubercles wanting, or not more than two ; mandibles not 

 recurved ; mesonotum with two longitudinal sulci ; scutellum 

 entire; posterior femora mutic ; fore wing with two cubital 

 cells ; hind wing with two or three complete cells ; abdomen 

 more or less concave beneath Stenophasmid^. 



Roman (Arkiv for zoologi, xi. 1917) states that the structui^e 

 of the body, especially of the abdomen and legs, is sufficiently 

 characteristic to entitle them to rank as a family, and considers
