AUSTRALIAN HYMENOPTERA CHALCIDOIDEA, VII.—GIRAULT. 79 
hyaline but with a dusky blotch across from the distal third or more of the submarginal and 
whole of stigmal veins; the cephalic part of this stripe is rectangular, obliqued caudo-distad, 
wider than long (normal position) and is separated from the other much longer than wide, 
caudal portion (on caudal margin) by an oblique hyaline line; the caudal portion is parallel 
with the caudal margin and proximad of the axis of the first. About eight lines of discal 
cilia proximad of the hairless line. Marginal vein punctiform, the postmarginal very short, 
distinct, the stigmal moderate, distinct, a little over twice the length of the marginal, Hind 
tibial spur single, minute. Mandibles with three weak teeth. Axille narrow, barely separated. 
Thorax and head scaly reticulate. Scape a little compressed; club shorter than the scape, 
acutely conic-ovate, about three fourths the length of the funicle or a little more; pedicel 
distinctly longer than any of the funicle joints which are all a little wider than long but 1 is 
quadrate; funicle joints gradually widening distad. Frons moderately narrow; head rounded, 
face inflexed, cheeks a little over half the length of the eyes. Scutellum large. Ring-joint 
minute. 
From one female caught in forest, April 16, 1914 (A. P. Dodd). 
Habitat: Cloncurry, Queensland. 
Type: No. Hy 2976, Queensland Museum, Brisbane, the specimen on a tag, a hind tibia 
and a fore wing on a slide. 
GENUS ISODROMOIDES Girault. 
Somewhat similar to Isodromus Howard but the marginal vein not punctiform, the 
stigmal nearly twice longer than it but not especially long, the pleura of propodeum without 
dense white pubescence and the antenne bear a ring-joint, the elub solid, the antennz 
10-jointed. Head (cephalic aspect) slightly wider than long, the scrobes rather short, forming 
a triangle, distant from the cephalic ocellus, the antennz inserted near the clypeus, the club 
obliquely, acuminately truncate along one side, not half the length of the funicle where the 
first joint is cylindrical and as long as the pedicel, the distal joints wider than long but 
narrower than the club. Scape slender, pedicel long, the ring-joint very short. Eyes somewhat 
convergent dorsad, the lateral ocelli not quite touching their margins. Axille cuneate, meeting 
at the meson. Scutellum simple. Abdomen short, triangular, flat above, the ovipositor not 
exserted. Marginal vein about twice longer than broad, the postmarginal subvestigial, scarcely 
perceptible; fore wings fumated and with an oblique hairless line. Intermediate tarsi armed 
beneath with black teeth as in many eupelmine genera but here not quite so densely. Hind 
tibiz with one spur. The two lateral mandibular teeth acute, subequal, the mesal shorter and 
truncate. Somewhat similar to Meniscocephalus Perkins of the Ectromini. 
1. ISODROMOIDES TRIANGULARIS Girault. Female. Genotype. 
_ Length, 1.75 mm. 
Black, scarcely metallic but the distal margins of the scutellum verdigris green; tips 
of tibiz and all of each tarsus whitish yellow. Antenne suffused slightly with brownish. Fore 
wings entirely embrowned except proximad out as far as the end of the submarginal vein, the 
fumation accented under the marginal and stigmal veins, Venation brown. Head and thorax 
densely, finely punctate, the punctures formed by reticulation. Axille smoother. 
Habitat: Townsville, Queensland, Parasitic upon EL pipyrops doddi Rothschild. Jungle? 
Avril 28, 1903 (F. P. Dodd). Many females. 
Types: No. Hy 2977, Queensland Museum, Brisbane, three females on a card; hind legs, 
antenne, a head and fore wing on a slide. 
wr. A. P, Dodd kindly identified the host, a tineid parasitic upon Fulgoridw and whose 
peculiar habits are described in Novitates Zoologice, XIII, 1906, pp. 162-169. In the second 
paragraph of p. 166, it is stated ‘‘ The ichneumons all issue from the one hole, and the earlier 
ones to emerge are finely powdered.’’
