 above the vertex-ll -jointed with two ring-joints, 

 the club solid and terminating in a nipple-like pi'o- 

 jection, the funicle joints long, the first ])lainly nioi'e 

 than twice the length of the short .pedicel and twice 

 the length of the distal funicle joint. Maxillary palpi

 veins well developed, the former a thh-d longer. 

 Parapsidal fiu'rows obscure, only about half complete 

 (from cephalad). Abdomen subsessile, ovata, de- 

 pressed above, produced ventrad beneath, the ovi- 

 positor not exserted. Propodeum without spira- 

 cular sulci nor carmae, the spiracle moderately small, 

 oblong. Second abdominal segment longest. Po- 

 sterior tibiae with two sf)urs. Non metallic. Eyes 

 practically naked. Pronotum as seen from above, 

 transverse-linear, widening laterad. 



Male: — Not knowrn. 



Type: The following species. 



1. A pire ne 1 o n g i f a s c i a t a new species. 



Female: — Length, 2.60 mm. 



Black, the abdomen honey yellow and with a 

 long, broad black stripe do\vn each side from base 

 to apex; coxae black, the legs fuscous, the tips of 

 the tibiae and most of tarsi paler, the cephalic femora 

 darker, washed with more or less blackish. Wings 

 hyaline. Head and thorax densely but not deeply 

 pmictate, the propodeum less rough, polj'gonally 

 reticulated, the abdomen all similarly reticulated but 

 more delicateljr. Pace with converging striae above 

 the clj'peus. Second and thhd funicle joints sube- 

 qual, the third, fourth and fifth each shortening. 

 Scape and pedicel fuscous, ring-joints yello^vish, the 

 funicle yellow suffused with dusky. 



(Prom two specimens, similarly magnified.) 



Male: — Not known. 



Described from two females captured by Mr. 

 Alan P. Dodd at Nelson, North Queensland by 

 sweeping in a forest, December 3 and 4, 1912. 



Habitat: Australia-Nelson, Queensland. 



Types: In the Queensland Museum, Brisbane, 

 the above specimens mounted on separate tags plus 

 a slide bearing a head and its appendages. 



Sphegigasterini . 

 Pterosema Foerster. 



1. Pterosema unicolor new species. 



Female: — Length, 2.50 mm. Moderately ro- 

 bust. 



Very dark metallic green, the antennae, tegulae, 

 legs (except coxae) and venation fuscous, the wings 

 hyaline and the scajDe fulvous ; femora and tibiae 

 (except cephalic ones) washed with more or less 

 metallic purplish. Head and thorax densely poly- 

 gonaUjr reticulated, the areas nearly deep enough 

 for punctures, the clj'peus longitudinally striate, the 

 abdomen finely reticulated, including its short but 

 distinct petiole. Vertex ^vide, the lateral ocelli very 

 distant from the eye margins. Antemiae inserted 

 slightly above an imaginary line drawm betw-een the 

 ventral ends of the eyes, 13-jointed, the scape long 

 and slender, two rmg-joints, three club joints, the 

 pedicel slightly longer than the first funicle joint, the 



latter slightly wider than long and longest of the 

 funicle. Posterior tibiae with one spur. Mandibles 

 3-and 4-dentate. Marginal vein slender, moderate 

 in length, only subciiual to the long postmarginal vein 

 which is a fourth longer than the long, slender, cur- 

 ved, stigmal vein. Parapsidal furrows complete. 

 Propodeum with a distinct neck and median and 

 lateral carinae, its disk reticulated like the rest of 

 the thorax, the spiracle small, oval, near the post- 

 scutellar margin, the sulcus more or less obscure, 

 perhaps absent. Abdomen petiolate, conic-ovate, 

 somewhat produced beneath, as long as the thorax, 

 the second segment equal to a third of the length of 

 the body of the abdomen, segment 3 somewhat shorter 

 than 4, subequal to 5, segments 3 and 4 combined 

 in length subequal to 2; distal edges of abdominal 

 segments very slightly convexed at meson but not 

 excised. 



(From six specimens, similarly magnified). 



Male: — Unknown. 



Described from six females mounted together on 

 a card in the collections of the Queensland Museum, 

 labelled „Bred from cocoon of Bombj'x Moth. 3-7-11, 

 Brisbane, H. Hacker, 4-7-11". 



This species resembles a Hypo ptero malus, 

 but the petiole of the abdomen is longer, the ab- 

 domen shorter and less produced beneath. H y- 

 popteromalus has 3-and 4-dentate mandibles 

 and camiot therefore, belong to the Pteromalini as 

 limited by Ashmead. 



Habitat: Australia-Brisbane. Queensland. 



Types: In the Queensland Museum, Brisbane, 

 five of the above specimens on a card (1 pin), plus 

 a slide of xylol-balsam bearing posterior legs, a head 

 and several antemiae. 



Subsequently, two males and rine females were 

 found in the same collection, bearing the same data; 

 the male has the legs more uniformerly fuscous. 

 Pterosemella new genus. 



Male: — Agreeing with Pterosema Foer- 

 ster, the parpasidal fuyows comiDlete but not deep. 

 Head large, much wider than the thorax, the eyes 

 slightly convergent above, the lateral ocelli theii' 

 own diameter from the eye margins, the ocelü m 

 an equilateral triangle. Antennae iirserted in the 

 middle of the face, 13-jointed, three ring and club- 

 joints, the pedicel shghtly shorter than the îiist 

 funicle joint, subequal to the second. Mandibles 

 4-dentate. Pronotum transverse. Axillae widely 

 separated. Scutellum simple. Propodeum with me- 

 dian and lateral carinae, its disk reticulated. Ab- 

 domen with petiole not quite as long as the posterior 

 coxae, the second segment verj^ long, occup^ing 

 three fom'ths the surface, its distal margin straight, 

 segment 3 much shorter. Posterior tibiae with one 

 spur which is slender. Postmarginal vem three- 

 foiu^ths the length of the margmal, the stigmal slender 

 but only two-thirds the length of the long postmar- 

 ginal. Clypeus bidentate. 



Female: — Not known.

 bed herewith.
