120 MANDIBULATA. H YMENOPTEEAa 



Mr. Haliday, in the place quoted, suspects this genus is referrible 

 to this family : as I have never seen the insect, I shall follow his 

 opinion, as from the description it evidently differs much from the 

 Braconidae. Mr. Shuckard informs me it is the Paxyloma De Breb.

 " OchreouSj shining ; antennte^ excepting the 2 basal joints, and head, excepting 



the mouth, blackish; back of thorax and apex of abdomen black, the base 



and middle of the latter fuscous ; stigma and nervures brown ; legs pale 



ochre ; posterior pair testaceous." — Curtis, I. c.

Antennw approximating, short, straight, filiform, 15-jointed in the males, 14- 

 jointed in the females ; basal joint short, ovate, rather stoutest; 2nd smallest, 

 minute ; 4th longer than the 3rd, 5th almost as long, the remainder gra- 

 dually decreasing in length to the apical one, which is somewhat longer than 

 the 4th : palpi rather unequal, filiform : head orbicular, attached by a distinct 

 neck: thorax narrow, compressed : wings rather short; anterior with 1 large 

 marginal areolet, 2 large submarginal ones, and 3 small irregular ones on 

 the disc : abdomen elongate, compressed, narrow, clavate, very slender at 

 the base: ovipositor exserted, long: legs short, posterior longest, their tibia 

 clavate, with a single spine at the apex, the anterior with one towards the 

 apex : tarsi moderate. 



The long clavate abdomen of both sexes of this genus, and their 

 clavate hinder tibiae, combined with the exserted ovipositor of the 

 females, the dissimilarity in the neuration of the wings, &c. sufficiently 

 indicate their distinction from the 3 preceding genera. These insects 

 frequent sandy situations, and are probably parasitic upon Pompili 

 and other Sphasgiform insects, Stelis phaeoptera, &c. 



Sp. 1. Jaculator. Niger, subnitidiis, abdominis segmentis 2-do, 3'-tio et i-to 

 pallide rvfis, tibiis tarsisque posticis annulo albo. (Long. corp. $ 5 — 6 lin.; 

 9 ovip. incl. 1 unc. 1 lin. ; Exp. Alar. G\ — 7 lin.) 



Si. Jaculator. Linne. — Foe. Jaculator. Steph. Catal. 343. No. 4006. 



Black, slightly glossy : head very minutely punctured ; thorax coarsely reti- 

 culate-punctate ; abdomen with the 2t)d, 3rd, and 4th segments pale red ; 

 ovipositor about as long as the rest of the insect, reddish ; legs black, the 4 

 anterior tibitc whitish at the base, the hinder pair with a white ring near the 

 base, and on the basal joint of the tarsi; wings hyaline, white.
