Stenophasmus, Monomuchus, Pelecimis und Megalyra. 239 



liegt auch darin ein Unterschied von den letztgenannten drei Gat- 

 tungen. Ich lasse hier Smith's Beschreibung wörtlich folgen. 



Genus Leptofoenus Smith. 



Leptofoenus Smith: Trans. Ent. Soc. Lond., Ser. 3, T. I, p. 43 . 1862 

 „Head globose, deeply excavated above for the reception of the 

 scape; antennae 13-jointed, short and stout, shorter than the thorax, 

 inserted in the middle of the face; the scape short, the two basal 

 joints of the flagellum minute, the third Joint rather longer than the 

 scape, the 4 — 9 joints each in succession shorter than the preceding, 

 the three apical joints minute, forming', as it were, a Single compressed 

 Joint, but really composed of three. The thorax elongate; the pro- 

 thorax prolonged into a neck; the wings without nervures, but with 

 transparent traces of neuration very similar to that of the genus 

 Pelecinus, the stigma distinct, the posterior margins of the wing 

 fringed with short hairs; the legs elongate, slender, the posterior 

 tibiae thickened at their apex. Abdomen elongate, the first forming 

 a petiole, the second longest ; the ovipositor a little shorter than the 

 abdomen. 



This genus is formed for the reception of an insect which ap- 

 parently unites in itself some of the characters of the genera Focnus 

 (Gasteruption), Megischus and Pelecinus-, it resembles the first in 

 the shortness of its antennae, Megischus in its globose head, 

 and Pelecinus in the almost totally obliterated neuration of its 

 wings." Smith. 



Leptofoenus peleciniformis Smith.

Ser. 3, T. I, p. 43, Q 18G2 



„L. niger, alis hyalinis venis obsoletis, tibiis posticis apice 

 dilatatis. — 



Female. Length 9 lines, of the ovipositor 5 lines. Black and 

 shining; the head with a few transverse Striae on the vertex; the 

 ocelli on a curve; the face thinly covered with short glittering pale 

 pubescence. The thorax transversely striated; the wings colourness 

 hyaline and iridescent; the anterior and intermediate legs very slen- 

 der; the posterior coxae stout, elongate, and transversely striated; 

 the tibiae slender, with their apex slightly thickened and pubescent; 

 the tarsi pubescent, the base of the joints ferruginous. Abdomen: 

 the petiole transversely striated; the following joints are smooth, 

 shining, and have a chalybeous iridescence, the valves of the ovi- 

 positor black, the ovipositor ferrugineous." Smith. 



Reg. V, Subreg. 2. Panama.
