above except the three apical segments, which are darker and some- 

 what metallic; venter pale at base, brownish medially and metallic 

 apically.

 expanded beneath, pedicel very short, flagellum tapering slightly from 

 base to apex; first funicle joint about twice as long as wide; following 

 joints successively shortening; club scarcely as long as the two last 

 funicle joints combined; mesoscutum and scutellum alike scaly- 

 punctate, mesopleurae mostly smooth; propodeum smooth; post- 

 marginal vein nearly as long as the marginal and a little more than 

 twice the length of the stigmal; abdomen reticulately lineolate. 

 Color dark blue-green; antennae black, the expansion of scape pale; 

 abdomen beyond the first segment brownish-black; all trochanters, 

 a line above and the apices of front and middle f emorae, front tibiae 

 outwardly for its whole length, basal third of middle and hind tibiae 

 and the three basal joints of the middle and hind tarsi yellowish-white;

Type.— Cat. No. 18331, U.S.N.M.

Family PTEROMALIDAE. 



Subfamily PTEROMALINAK. 

 TRIMEROMICRUS, new genus. 



Runs to Neocatolaccus in Ashmead's key and also in that of Nicko- 

 las Kourdumoff, but may be readily separated from that genus by the 

 venation and the lack of appressed hairs on the thorax. 



Antennae inserted on the middle of the face, with three ring-joints 

 and a distinctly jointed club; pedicel about as long as the first funicle 

 joint; joints of the funicle subequal and subquadrate; mandibles 

 each with four very short teeth; eyes ovate and practically bare; head 

 from in front not longer than broad, the clypeocular line a little longer 

 than half the height of the eyes, cheeks rounded; seen from above the 

 head is narrow antero-posteriorly, the occiput only slightly concave 

 and immargined, ocellocular line about equal to the lateral ocellar 

 line, the postocellar line fully twice the length of the ocellocular line; 

 face below the antennae not curved under; pronotum short and as wide 

 as the mesonotum; scutellum without a cross furrow; propodeum 

 short, without a neck, the spiracular sulci and lateral folds distinct, 

 spiracles distinctly elliptical; wings bare at base, the marginal and
