ART. 4 NEW PARASITIC HYMENOPTERA — GAHAN 23 



first funicle joint is a little longer than the second, and the antennal 

 club is equal in length to the funicle. Also resembles Encarsia por- 

 ioricensis Howard but differs by having the antennal club composed 

 of three joints the last two of which are pcorly separated, the mar- 

 ginal vein shorter than the submarginal, and the hind legs marked 

 with black. 



Female. — Length 0.9 mm. Antennal pedicel rather thick, almost 

 as broad as long; first funicle joint distinctly longer than pedicel and 

 slightly longer than second funicle joint; third joint the shortest, 

 fully twice as long as broad; club 3-jointed, not much thicker than 

 the funicle, the joints subequal in length, the two apical joints indis- 

 tinctly separated; vertex broad, the distance between the eyes at 

 vertex being greater than the length of antennal club ; lateral ocelli 

 separated from the eye margin by at least the diameter of an ocellus; 

 vertex transversely wrinkled, and with a transverse row of about 12 

 spines on the posterior margin separating it from the occiput; frons 

 apparently granuiarly sculptured and with numerous spines; eyes 

 hairy. Praescutum and the scutelium apparently with fine reticulate 

 sculpture; scutelium with four bristles, the posterior pair long and 

 closer to each other than to the lateral angle of scutelium; fore wings 

 normal in size; marginal vein shorter than submarginal, the latter 

 with two erect bristles; stigmal rather long, about one-third as long 

 as marginal; disk of wing behind submarginal vein bare, except for 

 a single row of cilia near the vein and extending from about the mid- 

 dle of vein to its apex; cilia covering the area behind marginal vein 

 distinctly longer and coarser than those toward wing-apex; longest 

 marginal cilia less than one-sixth as long as wing is broad; abdomen 

 as long and about as broad as thorax, rounded apically, the oviposi- 

 tor sheaths very slightly exserted; legs normal, tarsi all 5-jointed, 

 middle tibial spur slender and as long as basitarsus; the basitarsus 

 with several short thick spinelike bristles on the underside toward 

 apex. Head and thorax mostly pale yellowish; the antennae and 

 frons orange yellow; occiput, pronotum, anterior margin of prae- 

 scutum, pleura for the most part, propodeum, and abdomen brownish 

 black; legs mostly pale yellowish or whitish, the middle and hind 

 coxae and basal half of hind femora blackish, and the hind tibiae 

 stained with fuscous at base; wings hyaline with a transverse band 

 behind the marginal vein very faintly fuscous.
