Order Hymenoptera. Fam. Proctotrupidse. 



Type of the Genus, Ichneumon Punctum Shaw. 

 Mymar Hal., Curt. — Ichneumon Linn. ? — Shaw. 



JntenncE inserted in front of the head^ rather remote, very long, 

 filiform and 13-jointed in the male, basal joint long, slender in the 

 middle, clavate at the base and thickened before the apex, 2nd 

 joint short obovate, 3rd and remainder nearly as long as the first 

 joint, slightly tapering, terminal joint a little shorter, elliptic- 

 conic (1) : as long as the body, and geniculated in the female, 

 clavate and 9-jointed, basal joint longer and stouter than in the 

 male, but similar in form, 2nd short obovate, 3rd and 4th very 

 slender, the former scarcely longer than the 2nd, the latter longer 

 than the 1st, the 4 following submoniliform, gradually increas- 

 ing in size and length, 9th joint the stoutest, subelliptic (19). 

 Mandibles tridentate (3). 

 Head subglobose. Eyes round, lateral, not prominent, coarsely granu- 

 lated. Thorax subovate, gibbous and narrowed anteriorly. Abdomen 

 generally attached by a long slender pedicle; inserted at ike lower 

 portion of the base, obovate, the upperside being very much arched: 

 oviduct short but exserted (6). Wings; superior long and without 

 nervures, the costa thickened, apex ciliated with long hairs ; inferior 

 either very narrow or merely a short rigid nervure. Legs long and 

 slender. Thighs incrassated in the middle. Tibiae a little thickened 

 towards the base and apex, with a minute spine at the apex. Tarsi 

 4-jointed, basal joint the longest, 3rd scarcely shorter than the 4th 

 which is a little dilated at the apex, and terminated by minute Claws 

 and Pulvilli (8, afore leg). 

 Obs. The dissections and descriptions are taken from the species figured. 



PuLCHELLUS Walk. — Curt. Guide, Gen. 586. 12. 



Ochreous shining, slightly pubescent: eyes black : wings, supe- 

 rior formed of a long costal nervure, producing a blackish mem- 

 brane only at the apex, the basal half of which is white and trans- 

 parent, the edges and apex pilose with a longitudinal line of 

 bristles, the margin beautifully ciliated with long hairs ; inferior 

 rudimentary only : terminal joint of tarsi fuscous. 



In the Cabinets of Mr. Walker, Mr. Haliday, and the Author. 



Amongst other peculiar characters that mark this group, the 

 tetramerous tarsi, and the structure of the wings, especially 

 the inferior, which in some species form only a rigid nervure, 

 must not be overlooked. In dissecting the head 1 discovered 

 a mandible which was tridentate as represented in the plate, 

 and I thought I could distinguish a mentum and maxillae, but 

 not a vestige of palpi.
