The Hymenoptera of the Georgetown Museum. 131 



Bred from Limacodid, Phobetron hipparchia. 



Head closely, not very strongly punctured, the vertex sparsely covered 

 with longish black, the front with shorter white hair. Thorax : the pro- 

 notum almost smooth ; the mesonotum and scutellum closely, regularly 

 distinctly punctured, the scutellum slightly more finely than the mesonotum, 

 the pleurae smooth and shining as is also the metanotum, which has a wide 

 rounded keel down the centre, bordered by wide, deep furrows, rounded on 

 the outerside. 



EXTEDONINJL 

 Tetracampini. 



Akonda, gen. no v. 



Antennas 10 ? jointed, placed immediately over the clypeus and below the 

 eyes, the last joints forming a club. Eyes pilose, the malar space one-third 

 of their length, obliquely narrowed to the mandibles. Temples short, roundly 

 narrowed. Ocelli in a wide triangle. Pronotum distinct, roundly narrowed 

 to the base. Mesonotum with the parapsidal furrows only indicated 

 on the apical half. Scutellum large, wider than long, transverse at the base, 

 roundly narrowed at the apex. Metanotum semi-circular, large, the sides 

 margined, a finer keel down the centre. Submarginal vein short, narrow, 

 thickened at the apex, one-fourth of the length of the margiual, which is 

 longer than usual ; post-marginal very short, the stigmal is as long as the 

 latter placed close to it and dilated at the apex. 1st abdominal segment as 

 long as the following united, broad at the base, longer than it is wide at the 

 apex, cup-shaped ; the other segments become gradually narrowed to the 

 apex, and are of about the same length. 



The flagellum is stout, the joints wider than long, but not much, the 

 scape distinctly narrower than it. The lower part of the mesopleurae is widely 

 depressed. 



Belongs to the Tetracampini and comes, of the known genera, nearest 

 to Tetracampe, from which it may be known by the pilose eyes, more sessile 

 1st abdominal segment and much shorter post-marginal nervure. 



Akonda hipparchia, sp. n. 



Blue, the apical half of the abdomen (from the apex of the 1st segment) 

 black tinged with violaceous, the antennal scape and the legs whitish yellow, 

 the coxae blackish blue ; antennal flagellum black, pilose ; wings hyaline, 

 the nervures pallid testaceous. Sparsely pilose, smooth, except the meso- 

 notum which is finely closely reticulated. Female. Length, 1 mm. 



Bred from Limacod Phobetron hipparchia.
