AntenncE inserted in front of the face, long, slender, submonili- 

 form, pubescent, containing from 30 to 50 joints, basal joint 

 obovate robust, 2nd globose, 3rd slender, 4th and following 

 subquadrate, terminal ovate (fig. 1 a). 

 Labrum triangular, pilose, membranous at the apex (2) . 

 Mandibles remote, lateral, not crossing each other, subquadrate,

 Maxilla; with the lobes coriaceous, external one membranous at 

 the edge, pilose ; internal one acute. Palpi very long, pilose, 

 G-jointed, basal joint short slender, 2nd short robust, 3rd and 

 4th long, the former robust, 5th nearly as long as the 6th (4).

 view (f the head), lliorax ovate. Abdomen attached by a very 

 short peduncle, rugose at the base, slightly depressed in the males,

Li the Cabinet of the Author. 



Alysia approaches very near to Bracon, especially in the 

 structure of the wings, which are however ahke in both sexes ; 

 the labial and maxillary palpi have a joint more than those of 

 Bracon, and its tridentate jaws so remarkably situated, at once 

 distinguish it from all other genera.
