AUSTRALIAN HYMENOPTERA CHALCIDOIDEA, XII.—GIRAULT. 285 
of fine, indistinct discal cilia (only about eighteen in compressiventris). Also, the postmarginal 
vein is as long as the marginal. Hind tibial spur single, long and slender. 
From one female captured on the window of a wool warehouse, October 30, 1911. 
Habitat: Brisbane, Queensland. : 
Type: No. Hy 3309, Queensland Museum, Brisbane, the above female on a slide. 
EPICOLYSTICHUS new genus. 
Female :—Exactly similar to the preceding but there are three ring-joints instead of two, 
the antenne 13-jointed; also the abdomen is somewhat less compressed, the propodeum is 
somewhat longer and with delicate median and lateral carinew, the isolated small round spiracle 
central (apparently the same in the preceding but the spiracle larger and in its usual position 
cephalad but I could not be certain). The hind tibizw bears two spurs of which one is long and 
slender as in Paracolystichus, twice the length of the other. Otherwise, the two agree. 
1. EPICOLYSTICHUS HREICORPUS new species. 
Female :—ULength, 1.25 mm. 
Like the preceding species but the thorax less coppery or brown, the tibiz and tarsi 
reddish brown and the scape yellowish except at distal third. The antennew very similar. 
Lateral ocellus distinctly not touching the eye margins. Abdomen sculptured much like the 
thorax. 
From six specimens found on flowers of a forest tree, January 4, 1913. 
Habitat: Gordonvale (Cairns), Queensland. 
Types: No. Hy 3310, Queensland Museum, Brisbane, three specimens on a tag, a head 
and hind leg on a slide. 
GENUS TRICHAULUS Mayr. 
1. TRICHAULUS AENEICORPUS new species. 
Female :—Length, 1.33 mm., excluding ovipositor. 
Dark neous, the wings hyaline; knees, tibiz and tarsi pale and distal portion of femora. 
Antenne and ovipositor black. Thorax and abdomen uniformly scaly reticulate. Flagellum 
clavate; funicle 1 twice the size of either ring-joint, increasing in size, 5 longest, shorter than 
the pedicel. With the habitus of Hupelmus; slender. Antenne 13-jointed with three ring- 
joints, the funicle joints wider than long, the club 3-jointed. Parapsidal furrows complete. 
Secutellum convex, simple. Mandibles weakly tridentate. Stigmal vein with a short neck, a 
fourth the length of the marginal, a little shorter than the postmarginal. Abdomen sessile, — 
elliptical oval (dorsal aspect), segments 2 and 6 together occupying three fourths of the 
surface, 2 longest, their caudal margins incised at meson; ovipositor not quite as long as the 
body; segment 2 occupying a third of the surface, 6 not much shorter than it. Propodeum 
noncarinate, plane, the spiracle round, cephalad. Mesepimeron not incised. Hind tibial spur 
single, small. Hind femur simple. Parapsidal furrows ending laterad before the pronotum. 
Front femur somewhat distinctly swollen but unarmed. 
From one female captured in forest, December 24, 1911. 
Habitat: Double Island (mainland) Cairns, Queensland. 
Type: No. Hy 3311, Queensland Museum, Brisbane, the specimen on a tag; head and 
hind legs on a slide. 
KOEBELEA new genus.* 
1. KOEBELEA FUSCA Girault. Female. Genotype.
