hairs. Fnnicle 3 quadrate, larger than the pedicel; club 1 largest, wider than 

 long, 3 at apex with an inset tubercle-like joint which bears the terminal nipple 

 and appears to be articulated (if so, club 4-jointed). Mandibles 6-dentate. 

 Propodeum with a delicate but distinct median carina, no others but a sulcus 

 runs along the caudal margin from the meson to about opposite the not ver^/ 

 large spiracle and which narrows mesad. Postscutellum large, nearly half the 

 length of the scutellum, sculptured like the latter. Propodeum subglabrous 

 between the spiracles, otherwise scaly like the rest of the thorax. Axillae much 

 advanced. Parapsidal furrows eephalad, very short, the scutum with the usual 

 constriction eephalad. Segment 2 of abdomen occupying about one third of the 

 surface, mostly smooth, rest of the depressed abdomen delicately scaly. Scutel- 

 lum with a finer surface than the scutum, the latter very densely scaly-punctate. 

 Head sculptured like the thorax. 



Redescribed from the type in the U. S. National IMuseum. "Australia — 

 Koebele." 



HEMIPTAESENOIDEUS new genus. 



Female: — In Ashmead's table runs to Hemiptarscnus Westwood but 

 differs in bearing four funicle joints and two club joints. Head triangular, the 

 antenuiB inserted in the middle of the face, the long scape extending above the 

 ocelli. Club with a distinct terminal nipple. INIarginal vein long and slender, 

 somewhat longer than the submarginal, the postmarginal sul)elongate, dis- 

 tinctly longer than the well-developed stigmal. Abdomen with the second 

 segment occupying about a fifth of the surface ; a short distinct petiole is present, 

 the body of the abdomen conic-ovate. Form slender. Proximal joint of caudal 

 tarsi elongate, the caudal tibial spur distinct. Legs slender. Spiracle of propo- 

 deum minute, round, a little caudad of cephalic margin, lateral carina? present, 

 very delicate, straight, a median carina at base but rather weak and one third 

 complete. Axilla? but slightly advanced, widely separated. Pedicel smallest of 

 the antennal joints. Two ring-joints, the first very short. Mandibles 4-dentate. 

 Stigmal vein about a fourth the length of the marginal. 



HEMIPTAESENOIDEUS SEMIALBICLAVA new species. 

 Female: — Length, 1.45 mm. 



]\Ietallic purplish green, the abdomen black-purple, the wings hyaline, the 

 venation brownish ; coxge and caudal femora concolorous, also distal three joints 

 of caudal tarsus and a little over distal third of caudal tibia?; scape (except 

 above at middle), second club joint with its terminal spine and rest of legs, 

 white except the distal three tarsal joints. Funicle 2 longest of the funicle, 

 subequal to 1, 3 and 4, each slightly shorter in succession ; 1 is nearly as long as 

 the body of the scape and about 3 J times longer than wide; 4 only about two 

 thirds the length of 2, subequal in length to the club. Pedicel a little longer 

 than wide at apex, not half the length of 1. Ring-joint 2 rather large. Thorax 

 finely scaly, the propodeum subglabrous between the lateral carinae, except near 

 proximal margin, the abdomen much smoother, shining. Postscutellum shining. 

 Middle femora metallic. 



The male is about the same except in the abdomen and the antennge, the 

 latter bearing long, serrated or rather short-plumose rami one each from funicles 

 1-3 (from the same side and originating near apex), these rami are much longer
