AUSTRALIAN HYMENOPTERA CHALCIDOIDEA, VII.—GIRAULT. 129 
to 2 and longest; 1 or 2 about one and a half times longer than wide, 3 a little longer than wide, 
4 a little wider than long, 6 distinctly wider than long. Frons broad; cheeks as long as the 
eyes. Flagellum hispid. Metapleurum not noticeably pubescent. Hind tibial spurs distinctly 
unequal but distinct; hind tarsi white, proximal portion of first tarsal joint of hind legs 
purple. Ring-joint absent. 
From two females captured while crawling over the stems of an Hibiscus in a garden, 
October 30, 1911. 
Habitat: Mossman, Queensland. 
Types: No. Hy 3052, Queensland Museum, Brisbane, two females on a tag; head, a fore 
wing and a hind tibia on a slide. 
The Hibiscus plant mentioned was badly infested with a lecaniid and ants were also 
constantly running to and fro in large numbers. The encyrtid resembled the latter somewhat, 
walking very rapidly and unevenly and jumping strongly when disturbed. 
Another female of this species was taken by miscellaneous sweeping (including Hibiscus 
and other ornamentals in neglected gardens) along the Herbert River at Halifax, February 26, 
1913. In this specimen, the hind legs were coloured like the others. 
2. EUCOMYS ARGENTICOXA new species. 
Female :—Length, 1.80 mm. Robust. 
Like the preceding but the antenne are black, the scape silvery white, black along dorsal 
edge; pronotum metallic purple except laterad; scutum metallic purple at distal half, the purple 
advanced a little at meson and with dense whitish pubescence; thorax on each side of scutellum 
(dorsal aspect), purple. Middle cox purple, the others silvery; tarsi, knees and most of middle 
tibie pale, other tibiz purple, other femora white, purple along dorsal edge. Disk of occiput 
purple. Cheeks with conspicuous long bristles along ventral half (present in hibisci). Lateral 
ocelli distinctly separated from the eyes. Antennal segmentation differs in that the joints are 
all a little longer, funicle 1 being subequal to the pedicel; the pedicel is subcompressed in both 
species. Mandibles shorter. Antenne inserted on a level with the ventral ends of the eyes 
in both species. The fore wings differ, being blackish rather than brownish. Propodeum 
shagreened, purple at the spiracle. Rest of thorax finely longitudinally lined. Hind tibial 
spurs and hind tarsi the same. 
From one female caught in jungle, March 1, 1914. 
Habitat: Gordonvale (type) and Ingham, Queensland. 
Type: No. Hy 3053, Queensland Museum, Brisbane, the specimen on a tag; head, fore 
wings and a hind tibia on a slide. . 
Also one female, Ingham, March 30, 1914 (A. P. Dodd). 
3. EUCOMYS AURANTIFASCIATA new species. 
Female :—Length, 1.65 mm. 
Similar to argenticoxa but the cephalic margin of scutum is purple followed by a rather 
narrow transverse stripe of orange yellow, the rest purple, the cross-stripe of orange straight 
and thus the caudal purple on scutum has a straight cephalic margin. Also, the propodeum is 
wholly purple. Otherwise very similar. Cephalic margin of seutum narrowly black and also 
of the scutellum. Cephalic femur purple dorsad only at distal third (about distal half in 
argenticoxa). 
From one female caught on a window, January 11, 1912. 
Habitat: Innisfail, Northern Queensland. 
Type: No. Hy 3054, Queensland Museum, Brisbane, the specimen on a tag.
