ART. 24. NEW REARED PARASITIC HYMENOPTERA GAHAF. 21 



rugulose. subopaque, the parapsidal grooves posteriorly delicate but 

 distinct; scutellum longitiidinallj^ aciciilate-striate, somewhat shin- 

 ing; axillae similarly sculptured but the lines are not longitudinal; 

 propodeum mostly smooth, but with the spiracular grooves more or 

 less distinctly foveolate and a weak groove on each side of the median 

 carina and contiguous to it faintlj^ sculptured ; postmarginal vein of 

 forewing very nearly twice as long as the stigmal ; marginal nearly 

 twice as long as postmarginal; second joint of hind tarsi longer than 

 the metatarsus; inner spur of hind tibia twice as long as the outer 

 spur and subequal in length to the metatarsus ; hind coxae reticulate ; 

 abdomen approximately twice as long as broad, about equal in length 

 and breadth to the thorax, subovate in outline and perfectly smooth ; 

 ovipositor not exserted. Black with the frons and face slightly 

 metallic green; antennal flagellum dark brown; scape, legs and a 

 little more than the basal one-third of abdomen pale yellowish ; hind 

 coxae on the outer face piceous black, hind tibiae at apex brownish; 

 wings hyaline. 



Male. — Length 1.6 mm. Agrees in every way with the description 

 of the female. 



Type locality. — Caguas, Porto Rico. 



Type.— C2it.' 1^0. 25063, U.S.N.M. 



Type female, five paratype females and the allotype male received 

 from G. N. Wolcott with the statement that they were bred from 

 larvae of Prenes nero Fabricius, May 10, 1921.

This species apparently differs from the description of the genus 

 Paruscanoidea in that the hind wings are rounded at apex, the 

 ovipositor is not at all extruded beyond the apex of abdomen, and 

 the antenna is apparently 5-jointed, consisting of scape, pedicel, an 

 obscure ring-joint, and a two-jointed club. In other characters and 

 especially in the absence of discal cilia and the long marginal vein 

 of the forewing (pi. 1, fig. 6), which are the most striking features 

 of the genus, it seems to agree exactly with Girault's description of 

 Paruscanoidea and the characters in which it disagrees are so slight, 

 the presence or absence of an antennal ring-joint being especially 

 difficult to make sure of, that I am inclined to believe it belongs to 

 this genus. The color pattern of the body and wings agrees closely 

 with P. dickensi Girault and there seems to be no room for doubt that 

 the two species are related. If this conjecture is correct, then Pseu- 

 dohrachysficha is a synonym of Paruscanoidea, The matter can only
