lum roundish with lateral carinae; wings hyaline, iridescent, pubescence 

 at tij) of forewing dense enough to make tip appear darker in trans- 

 mitted light, nervulus postfurcal by one and one-third its length. 



Abdomen polislied, minuteh^ punctate, punctures on first tergite 

 very sparse; petiole flat dorsally, postpctiole widest at the spiracles, 

 its apex not quite twice as wide as petiole base. 



Head and thorax yellow with the following black: ocellar triangle 

 and a narrow stalk extending back from ocellar line and widening 

 greatly to occipital carina then narrowing to foramen magnum; two 

 spots on the mesopleuron, the upper one running diagonally across 

 the middle, the other below and extending onto the venter; three 

 stripes on the mesoscutum, the middle one beginning at the base and 

 running about two-thirds the distance to the apex, the two lateral 

 stripes beginning at the basal third and extending to the apex; most 

 of disk of scutcllum; disk of postscutellum; a spot on each side of the 

 propodeum just dorsal and anterior to the propodeal spiracle. Legs 

 yellow except the following which are piceous or dark brown: a small 

 basal spot on hind coxa, most of hind trochanters, stripe on outer 

 side and inner face of hind femur, basal and apical annulus on hind 

 tibia, middle and hind tarsi, and last two segments of each front 

 tarsus. Ovipositor sheatlis, petiole, and base of postpctiole black, rest 

 of postpctiole yellow; remainder of abdominal tergites reddish yellow 

 with more than basal half of tergites 2 and 3 and less than basal half 

 of remaining tergites blackish or dark brown. Antennae and ^^^ng 

 nervures yellowish brown; ovipositor reddish brown. Tj^pe has left 

 forewing and left middle leg missing. 



Allotype, male. Similar to female. Black spots on mesopleuron 

 smaller, the lower one ahnost nonexistent. Antennal flagellum with 

 29 segments, 



Tliis species is ver}^ close to //. convergens (Cushman), from which 

 it may be distinguished by the complete lack of a pale annulus on the 

 antenna; by the lateral carinae reaching the costulae; by the more 

 slender ovipositor; and by the sliglitly longer and more slender basal 

 flagellar segment of the antenna. Color pattern of the tv\-o species 

 is very similar. //. convergens has less black on legs and less reddish- 

 j^elloAv on abdomen. 



Described from two specimens, female and male, from St. Augustine, 

 Trinidad, British West Indies, collected in May 1953 by F. D. Ben- 

 nett. A tliird specimen is too broken to include in the tj^Q series. 



Holotype, female, and allotype, male, aie in the U. S. National 

 Museum collection under type No. 62052. 



A headless specimen from Vene.uela in the Townes collection is 

 either this species or a new species closely related to cosmeta.
