AUSTRALIAN HYMENOPTEBA CHALCIDOIDEA, IV.—GIBAULT. 29£ 



1. HETREULOPHUS BIFASCIATIFRONS new species. Genotype. 



Female: — Length, 1.30 mm. Ovipositor about a sixth the length of the abdomen, its 

 proximal two thirds white, rest black. 



Orange yellow, the abdomen pale whitish yellow, dorsad washed with purple except 

 proximad; pronotum washed with purple. Face with two interrupted metallic purple lines 

 across a little above the antennae, the lines separated for some distance and parallel; dorsal 

 head lightly purplish, lemon yellow ventrad. Propodeum and axillae washed with purplish, 

 also more lightly, cephalic scutum. Legs orange yellowish, the cephalic and intermediate 

 tibiae purple, the hind coxa also but white toward and at tip. Hind knees white, the hind 

 tibia? purple dorsad. Antenna? yellowish brown, the last three joints jet black; scape long 

 and slender; pedicel longer than any of the funicle joints; ring-joint a little wider than 

 long; first three funicle joints distinctly narrower than the distal three, 1 longest, about twice 

 longer than its width but really not much longer than 7 which is a little longer than wide 

 and subequal to the three joints proximad of it (taken separately). Club without a terminal 

 nipple; not quite as long as the united lengths of the three preceding joints. Hind tibial 

 spur normal, small, the hind femur compressed. Scutum rather coarsely scaly; rest of thorax 

 more finely so, the scutellum densely, finely lineolated, bearing four large isolated, black setae. 

 Fore wings with marginal cilia and a small clump of short, stiff black setae upon the apex of 

 the submarginal vein, embrowned from a crescentic cross-stripe of deeper color a little- 

 proximad of the clump, the infuscation broken- — across extreme apex by hyalininess; against 

 the submarginal vein by a round hyaline spot adjoining which proximad is a somewhat 

 smaller fuscous spot (a similar spot opposite at caudal margin) and by a longer than wide 

 hyaline area under the marginal vein. Discal cilia present on the hyaline areas as on the 

 infuscated region. Legs simple. 



From one female taken in jungle, February 10, 1914 (A. P. Dodd). 



Habitat: Babinda, Queensland. 



Type: No. Hy2719, Queensland Museum, Brisbane, the specimen on a tag; head and 

 hind legs on a slide. 



In the table of subfamilies, antea, pp. 294-295, omit the Aphelinini; line 9, insert 

 usually before 4- jointed. In the Elachertinae, the axillae are frequently not advanced; p. 295, 

 line 4, omit the word incomplete; line 8, omit the first two words; line 9, omit words 2-8; lines 

 10 and 12, five should read none; line 12, omit all words in parentheses following the semi- 

 colon; line 16 omit the interrogation point. 



All the members of this family as soon as obtained should be killed by immersion in 

 alcohol and preserved in that medium until the specimens are ready for study. The head 

 should be mounted separately in balsam after being removed and divided into two by pressing 

 a needle or ordinary insect-pin along the face between the antennal bulbs. In this way, 

 assurance of seeing the ring-joints, which must be pressed out, is made. Shrivelling is to be 

 avoided. Accuracy is an essential in descriptions.
