postmarginal vein somewhat longer than the nonsessile, curved, 

 stigmal vein. Pedicel twice longer than wide at apex, nearly 

 twice longer than funiclc 1, the latter a very little longer than wide, 

 longest yet subequal to 2; 6, twice wider than long; club with the 

 joints (or two divisions) subobsolete. Second ring-joint larger 

 than the first. Head and thorax finely cross-lined, the lines on 

 the thorax not raised. Axillae, scutellum laterad and the pro- 

 podeum longitudinally lined, the thorax dorsad (except the pro- 

 podeum between the spiracles) with prostrate, long pubescence 

 from scattered minute punctures. Propodeum with a pair of 

 widely separated median carina?. Abdomen glabrous at immediate 

 base, roughly scaly elsewhere; line 1 of large punctures double 

 mesad, base of segment 3; 2, base of segment; 4, double; 3, base of 

 segment; 4, inclined to be triple in places; no others; a median 

 carina from base of segment 3 to middle of 5; segments 3-5 with 

 a scalloped cross-ruga at about middle. Like the Australian 

 species. The basal of the two lines of punctures on abdominal 

 segments is ^t first of half-punctures but these become more com- 

 plete distad, complete in line 3 



From one female on a tag in the U. S. National Museum from 

 Louisiana (C. F. Baker). 



Type— Catalogue No. 20327, U. S. N. M., the foredescribed 

 specimen and a slide bearing a fore wing and an antenna. 

 HabrolepDidea depressa, new species. 



Female — Length 1.15 mm. 



Body depressed, the ovipositor a little extruded yet distinctly 

 so. Dark metallic purple, the wings hyaline, the legs coloured as 

 in Aphidencyrtus aphidiphagus (Ashmead) from which this species 

 differs as follows: The mandibles have the third tooth small, 

 subacute (bidentate but the broad second tooth is rather deeplv 

 concaved at apex), the frons is moderately broad, the form de- 

 pressed, the marginal vein is subequal to the stigmal and post- 

 marginal veins. Venation black. Body very finely, micros;:opic- 

 ally scaly, shining, the axilla? glabrous. Pedicel subelongate, 

 much longer than any funicle joint; funicle joints subquadrate 

 but enlarging distad. Club wider than the funicle and three- 

 fourths its length, obliquely truncate from base of joint 3. Scape 

 with a distinct ventral exfoliation but this is not greatly convexed.
