vest of antenna black. Head and thorax finely scabrously punctate, the pronotum and 
mesonotum with a short, greyish pile. Venation sooty. Abdomen smooth but reticulated 
polygonally. Scape short; pedicel shorter than any of the funicle joints, which except the 
first, are wider than long, the first somewhat longer than wide; six funicle joints. Hind femur 
sculptured like the thorax, the hind coxa also and it is flat laterad. 
Habitat: Little Mulgrave River (Cairns), Queensland. Jungle, June 7, 1913. 
Type: No. Hy 3387, Queensland Museum, Brisbane, the male on a tag. 
Ose male, Gordonvale, May 23, 1914. Forest. 
MIROCHALCIS new genus. 
Female :—Like Chalcis Fabricius but the hind femur at distal half (a little beyond) 
with a tooth inwardly somewhat ventrad of the middle, the hind tibize compressed, with only 
three sides, its margins carinated and mesad (inwardly) below knee with a large triangular, 
impressed plate with raised margins and forming an obtuse hump on the dorsal side. Antenne 
12-jointed with one ring-joint. Abdomen with only two dorsal segments, the others retracted 
within, the region globate. Hind femur at extreme apex prolonged laterad into an obtuse 
tooth on each side. 
1. MIROCHALCIS ATRICORPUS new species. Genotype. 
Female :—Length, 5.85 mm. 
Black, the wings hyaline, the venation black, the tarsi brown. Postmarginal vein twice 
the length of the stigmal or nearly but less than half the length of the marginal. Secutellum 
rather deeply emarginated at apex. Head, thorax and abdomen clothed with a fine down, the 
head and thorax densely punctate, the propodeum rugose but with a more or less distinct median 
channel with carinated sides and including cross-carine; spiracle very long, slotlike, curved, 
the ends wider. Along cephalic margin of scutum, midway between meson and lateral margin, 
an obscure impunctate area densely scaly. Third segment of abdomen with several rows of 
pin-punctures cephalad, then very finely punctulate, the last segment (retracted) rather 
coarsely punctate (but not by far like the umbilicate punctures of the thorax). Segment 2 
subglabrous, exceedingly finely punctulate. The pin-punctures on segment 3 are interrupted 
at the meson and spread laterad. Segment 2 occupying somwhat over half of the surface. 
Seape normal, the pedicel wider than long; funicle 1 distinctly longer than wide, 2 barely 
so, the distal funicle joint a little wider than long. Hind femur with ten moderate-sized teeth, 
more or less equal or gradating. 
Described from one female captured on December 3, 1912 (H. Hacker). The label read 
“¢ 3-12-12.’ 
Habitat: Stradbroke Island (Brisbane), Queensland. 
Type: No. Hy 3388, Queensland Museum, Brisbane, the specimen on a tag, the antenna 
on a slide with the type antenna of Chalcis brisbanensis Girault. 
MEGACHILOCHALCIS new genus. 
Resembling the forms of certain bees. Antennz 13-jointed with oue very short ring- 
joint, inserted on a line with the ventral ends of the eyes, the club 2-jointed. Seutellum a 
little below apex with a stout upeurved spine projecting over the propodeum, the latter pro- 
duced into a short, distinct, stout tooth on each caudo-lateral angle. Hind tibia straight, 
normal at tip. Postmarginal vein as long as the short marginal. Cephalic ocellus within 
the end of the scrobes. Hind femur beneath with a sloping convexity near tip which bears 
fine, comblike teeth as in Stomatoceras. Scutellum emarginate at meson of apex. Propo- 
deum with two short, obtuse teeth on each side.
