11. APROSTOCETUS NECOPINATUS new species 



!■'< mah : — Length, 1.10 mm. 



Dark metallic purple, the wings hyaline, the antennae, legs and abdomen, lemon yellow, 

 the abdomen margined rather broadly along proximal two thirds with metallic purple, purple 

 ;tt tip (not broadly) and midway between end of marginal stripes and tip, with a distinct but 

 narrow metallic purple cross-stripe. First coxa) concolorous. Pedicel and funicles 2 and 3 

 subequal, funicle 1 a little longer than either, one and a half times longer than wide. Mandibles 

 .somewhat as in bilongifasciatus, with 2 large, acute outer teeth and a minute acute inner one. 

 An obscure stripe indicated between the end of the marginal stripes on abdomen. Compared 

 with types of bilongifasciatus and tenuis and with those of SeliirichodeUa meteora and 

 S. purpureithorax Girault. 



From one female caught in jungle, January 17, 1914 (A. P. Dodd). 



Habitat: Gordonvale (Cairns), Queensland. 



Type : No. Hy 2560, Queensland Museum, Brisbane, the female on a slide. 



12. APROSTOCETUS SALTENSIS new species. 



/■'< male: — Length, 1.10 mm. 



Dark metallic blue, the wings hyaline, the following parts golden yellow : Head, abdomen, 

 antenna}, a little over distal fourth of scutum and lateral margins of same. Legs lemon yellow 

 except the concolorous hind coxa. Abdomen from base with three pairs of small blue marginal 

 spots (proximal half or somewhat less) followed by several transverse stripes on the distal 

 half. Fore wing rather narrow (about 16 lines of cilia where widest), the stigmal vein short. 

 Tip of abdomen colored. Funicle joints 2 and 3 subequal, barely shorter than 1 which is 

 slightly longer than wide and subequal to the pedicel; club with only a slight terminal spine. 



This species resembles somewhat OotetrasticJms subfasciativentris for which I mistook 

 it but besides the obvious generic differences, there is more blue on the scutum, the valves of 

 the ovipositor are not plainly extruded, the first funicle joint is short, there are only two 

 complete abdominal stripes (as far as I could make out), the wings are shorter and so on. 



From one female caught by sweeping in forest, December 24, 1912. 



Habitat: Capeville (Pentland), Queensland. 



Type: No. Hy 2561, Queensland Museum, Brisbane, the female on a slide. 



13. APROSTOCETUS BILONGIFASCIATUS new species. 



Female: — Length, 0.95 mm. 



Like tenuis but metallic purplish black, the abdomen honey yellow margined down each 

 side from base for about two thirds the way to tip, otherwise without markings, the valves 

 distinctly extruded, purplish along their distal halves, the propodeum and postscutellum with 

 a yellowish tinge ; head yellowish brown. Propodeum with a distinct median carina, the lateral 

 carina) apparently absent. Mandibles tridentate, the two outer teeth well developed, acute. 

 Funicle joints subequal, about two and a fifth times longer than wide, slightly shorter than 

 the elongate pedicel. Antennae filiform, the terminal nipple of club inconspicuous. Antenna? 

 and legs pale yellow. 



From one female captured by sweeping in forest. January 2, 1913 (A. P. Dodd). 



Habitat: Gordonvale (Cairns), Queensland. 



Type: No. Hy 2562, Queensland Museum, Brisbane, the specimen on a tag, the head
