(Type /.. iuniipta Hal.). 



(IM. xvir, Fig. r.,9.) 



Head rounded. Eyes small, protuberant, hairy. Ocelli 3, in atriaugle, 



Antenuji;, in 9 , 12-jointed, clavate, the scape cylindrical; the pedicel 



longer than the first Hagellar joint, the second to the last transverse- 



moniliform, slightly pedicellate, the last oval, twice as long as the pre- 

 ceding; in S , 14-jointed, filiform. 



Maxillary palpi obsolete; labial palpi not jointed. 



Mandibles bidentate. 



Thorax oblong, depressed ; prothorax attenuated into a neck; mesono- 

 tum with two furrows; scutellum transverse, subquadrate; metathorax 

 short, truncate at apex, with the angles a little prominent. 



Front wings with the submarginal vein not reaching the costa, termi- 

 nating iu a stigma but without a stigmal vein; basal vein subobsolete. 



Hind wings veiuless. 



Abdomen oblong, oval, petiolate. 



Legs normal, the femora stout, clavate; the tibiae subclavate. 



This genus has not yet been discovered in our fauna, and the single 

 species described by llaliday, from England, is the only one known. 



Tribe II. — Diapriini. 



In this tribe, the furthest removed from the Belytince, the submargi- 

 nal nervure reaches the costa at one-third its length or a little before, 

 the costal cell being most frequently open ; or the Gostal and subcostal 

 nervures are confluent as in the liraconidw [Loxotropa, Basalys, etc.); 

 or it is not, or but slightly, developed ( Galesm). Eleven genera having 

 these characteristics in common are here brought together. All those 

 of which the parasitism is known, are found living upon Dipterous larvfe.
