AVSTEALIAN RYMENOPTEBA CHALCIDOIDEA, V.— GIRAULT. 311 



median carina, its spiracle large and nearly round. Abdomen short and stout, no longer than 

 the thorax, its second segment occupying half of the surface. Scutellum longer than the 

 propodeum. Posterior tibiae apparently with but one apical spur. The male is the same, but 

 abdomen more depressed and cylindrie ; antennae entirely different, the scape much shorter, 

 dilated ventrally. pedicel not much longer than thick, the ring- joint like a ring; first funicle 

 joint very transverse and lamellate, following five joints increasing in length, each bearing a 

 long, curved, cylindrical ramus from its disto-lateral margin, joint 2 no longer than the 

 diameter of its ramus and practically forming a continuation of it, joint 3 slightly longer 

 Than wide; joint 6 much longer than wide; the rami longer proximad, the shortest and 

 distal one distinctly longer than any single joint of antenna. Proximal joint of club elongate 

 obconie, forming half of the club and longer than the distal funicle joint; the other two club 

 joints subequal. Funicle and rami with sparse, rather long, fine hairs. Male antenna? 

 12-jointed. 



1. MELANOSOMELLA FLAVIPES Girault. Female, male. Genotype. 

 Length, 3 mm. 



Black and shining; face, genae, legs (except coxas, the tarsi more brownish), scape 

 (except at tip where it is blackish), margins of eyes dorsad and caudad more or less obscurely, 

 lemon yellow; black of the vertex at meson projects obtusely into the yellow of face, some 

 distance directly cephalo-ventrad of cephalic ocellus. Tegula brownish. Fore wings with a 

 distinct brownish band nearly across it from the apex of submarginal vein; this stripe is 

 interrupted. Venation black. Antennal flagellum brownish, subfuscous. Face with thimble 

 punctures. Keniainder of body apparently simple and shining more or less. The fuscous stripe 

 on the wing of the male is subobsolete. 



Habitat: Xew South Wales. Galls on Eucalyptus. 



Types: No. By 1193, Queensland Museum, Brisbane, a pair on two tags, the antennae 

 on a slide. 



DIAGNOSIS OF THE AUSTRALIAN GENERA OF PERILAMPIDyE. 



Females. 



Abdomen sessile. Parapsidal furrows normal. 



Antennae inserted ventrad of the middle of the face, near the clypeus. Scutellum flat. 

 Axillae separated. 



Antennae 13-jointed with three ring-joints, the club 3-jointed; postmarginal vein 

 somewhat longer than the marginal, subequal to the stigmal. Nonmetallic; 

 impunctate .. Ccelocybomyia Girault (Type: C. sexfasciata Girault). 



Antennae 12-jointed with three ring-joints, the club 2-jointed; postmarginal vein 

 subequal to the stigmal and somewhat shorter than the marginal. Metallic, 

 impunctate. Scutellum with a punctate cross-furrow before apex 



Euccelocybomyia (Type: E. aerea Girault). 



Antennae inserted on or near the middle of the face; scutellum usually convex. Axillae 

 sometimes not separated. 

 Scutellum long, projecting caudad to middle of the abdomen but not produced at 

 apex; scape flat and broad. 

 Antennae 13-jointed with one ring- joint; postmarginal vein longer than the 

 marginal. Metallic; punctate
