AUSTBALIAN BYMENOPTEBA CHALCIDOIDEA, IV.—GIKATJLT. 281 



2. SYMPIESOMORPHELLEUS THOREAUINI new species. 



Female: — Length, 1.58 mm. 



Shining black, the legs, scape and a large wedgeshaped area in dorsal abdomen from 

 base, yellowish brown; the yellow abdominal area originates at base where it is narrower but 

 truncate; distad it extends not quite to middle and there is broadly truncate; for its entire 

 length it fills the abdominal dorsum except narrowly along each lateral margin (the margining 

 black, widening distad. Wings hyaline. Mandibles 6-dentate. Funicle joints subequal, oval, 

 1 a little the longest, larger than the globular pedicel; club ending in the usual nipple-like 

 " joint" (nonarticulated). Median carina of propodeum solid, the spiracle round, small, in a 

 roundish depression; a more or less distinct, obtuse spiracular " groove." Segment 2 of 

 abdomen occupying somewhat over a fifth of the surface, longest. Parapsidal furrows 

 represented by narrow carinas which curve off before reaching the pronotum which is transverse- 

 quadrate. Axilla? not advanced. Grooves of scutellum broadly separated distad (nearly for 

 entire apical margin). Thorax distinctly moderately coarsely scaly, the propodeum glabrous; 

 dorsal abdomen distad with very delicate scaly sculpture. Marginal vein nearly thrice the 

 length of the stigmal which is distinctly shorter than the postmarginal. 



From one female caught by sweeping forest, June 7, 1914. 



Habitat: Gordonvale (Cairns), Queensland. 



Type: No. HyS687, Queensland Museum, Brisbane, the specimen on a tag. 



Dedicated to Henry David Thoreau. 



3. SYMPIESOMORPHELLEUS PAUCIFASCIATUS new species. 

 Female: — Length, 1.75 mm. 



Orange yellow, the wings hyaline, the abdomen and legs a little lighter yellow, the 

 former narrowly margined down each dorsal edge with blackish and with two distinct, black 

 cross-stripes at distal third, the two joined along the meson by a short median black line. 

 Antenna? concolorous, all the funicle joints larger than the short pedicel, the first longest, 

 distinctly longer than wide, the others subglobular. Mandibles 7-dentate. Segment 3 of 

 abdomen only half the length of 2, which occupies about a fourth of the surface. Thorax 

 scaly. Median carina of propodeum paired, forking caudad. 



Described from one female caught by sweeping over all parts of island, a mile from 

 mainland, forest, December 25, 1911. 



Habitat: Northern Queensland (Double Island near Cairns). 



Type: No. HyS688, Queensland Museum, Brisbane, a female on a tag; head and hind 

 legs on a slide. 



4. SYMPIESOMORPHELLEUS ALBICLAVA new species. 



Female: — Length, 1.80 mm. 



Orange yellow, the abdomen honey yellow, the legs concolorous with the abdomen. 

 Scape and club yellowish white, pedicel and funicle 1 orange, other funicle joints black. 

 Abdomen narrowly obscurely margined with black from base to distal three fourths, the marginal 

 stripe broken into obscure dots. Fore wings slightly stained with yellowish. Antennae as in 

 nigriscutellum also the venation. Vertex lemon yellow. Thorax scaly, the scutum rather 

 thickly pin-punctured, the scutellum with only a few of these punctures. Immediate tip of 

 abdomen black. Postscutellum platelike. Propodeum glabrous, finely scaly laterad, with the 

 usual three carina? — also a carina just laterad of the spiracle. Segment 2 of abdomen occupying 

 a third of the surface. Mandibles about 8-dentate. 



From one female caught November, 1912. 



Habitat: Gordonvale, Queensland. 



Type: No. HyS689, Queensland Museum, Brisbane, the specimen on a tag; head and 

 hind legs with the slide type of Ewyscotolinx immarginatus.
