AUSTRALIAN HYMENOPTERA CHALCIDOIDEA, VII.—GIRAULT. 73 
scutum centrally (invasion from the pleurum), lemon yellow; tarsi brown. Antennal pedicel 
elongate, longer than the scape which is more convexed than in the female, the latter with all the 
joints distinctly wider than long and more or less equal. Antenna] club darker. Lateral 
ocelli somewhat farther from the eye than in the female. 
Habitat: Gordonvale (Cairns), Queensland. Forest. Reared from a spider’s egg-sac. 
Types: No. Hy 2970, Queensland Museum, Brisbane, two pairs on separate tags (four 
pins) and a slide with female fore wing and heads. 
TripE ARRHENOPHAGINIT. 
ARRHENOPHAGOIDEA new genus. 
1. ARRHENOPHAGOIDEA COLORIPES new species. Female, Genotype. 
Length, 0.85 mm. Differs from the genotype of Arrhenophagus Aurivillius in bearing 
5-jointed tarsi. The antenne are 5-jointed, quite as in Arrhenophagus—scape, pedicel and 
3-jointed club, the proximal two joints of the latter transverse-linear, the third joint four 
times their united length. Differs from Rhopoideus Howard in the shorter form, the lack of 
an oblique hairless line on the fore wing and in the short, thick antenne. The species is 
similar in every respect to Arrhenophagus chionaspidis Aurivillius excepting that the legs are 
all concolorous except the knees, tips of tibixw, tarsi, the intermediate legs and the cephalic 
tibiz which are yellowish. Also the middle tibial spur is stouter. No yellow on body. 
Habitat: Ingham, Queensland. February 17, 1913. 
Type: No. Hy 2971, Queensland Museum, Brisbane, the single female on a slide. 
The frons is broad, no substigmal spot but a marginal vein is indicated by a slight knot 
or swelling, which gives off a short, acute stigmal vein. The venation does not reach the costal 
wing margin. Middle tibial spur distinctly swollen or thick as normal. Hairless line of fore 
wing apparently absent. Type re-examined. 
A second species has been seen either from southern or western Queensland but unfortu- 
nately it was mislaid and I could not describe it from the parts mounted on a slide. The hind 
tibize were white, the fore wing with a more or less obscure hairless line and substigmal spot. 
GENuS ARRHENOPHAGUS Aurivillius. 
1. ARRHENOPHAGUS CHIONASPIDIS Aurivillius. 
According to Schmidekneckt (1909) Ashmead records this widely distributed species 
from Australia. I give its principal characteristics. 
Tarsi 4-jointed; antenne as in Arrhenophagoidea; fore wings without an oblique hairless 
line, the marginal, postmarginal and stigmal veins absent; marginal vein represented by a 
circular fumated spot. Shining black, the disk of abdomen with some yellowish dorsad. Antennz 
honey yellow, also the legs but dorsal aspect of caudal legs blackish and most of cephalic femur. 
A small yellow area just cephalad of tegula; a moderately broad, yellow fascia on upper face 
(on or near caudal margin of vertex). Mesothorax scaly but the seutellum finely, delicately 
longitudinally striate. Wings hyaline. Mandibles acute. Tibial spurs all small. Widely 
distributed—Europe, Asia, North America and Australia. I have seen specimens from Java and 
Porto Rico (West Indies). Parasitic upon various coccide of commercial importance. 
TRIBE ENCYRTINI. 
It is unfortunate but it is to be feared that this tribe will break down and fuse with the 
Ectromini. Species of the genus Anasiella Girault sometimes have bidentate mandibles. 
Cristatithoraz Girault is exactly similar to Cheilioneurus Westwood yet in different tribes. 
Two Australian genera are described with 4-dentate mandibles. Careful comparison of the 
genera of the two will show still other marked parallelisms. In the great majority of cases 
no doubt has been experienced as to the dentation but doubt exists as to the meaning of the
