50 Mr. R. E. Turner on the 



carina on each side further at the base from the enclosed 

 area than from the lateral margin of the segment. Abdo- 

 men smooth and shining ; sheath of the ovipositor short and 

 broad, subtruncate at the apex, scarcely one-third of the 

 length of the abdomen. Hind metatarsus somewhat 

 broadened, especially at the base, not cylindrical. Neura- 

 tion as in C. saltator, Fabr., but the distance between the 

 nervulus and the basal nervnre is only one-qnarter of 

 the length of the first discoidal cell on the discoidens, not 

 one-third as in saltator. 



Hab. Kuranda, N. Queensland (Turner), May 1913; 

 Mackay, Queensland (Turner) (type), March to May 1 ( J00, 

 August 1891. 



The wings are hyaline on the basal half in the specimen 

 from Kuranda. This species is very nearly related to 

 C. fuscipennis, Szep., and C. fasciatus, Szep., from New 

 Guinea, and may prove to be only a race of one of them, 

 but the descriptions are very brief. C. piliventris, Caifi., 

 and C. trichiosoma, Cam., from Waigiou, are also very 

 closely related.

? . This is very similar to the last species, except in 

 colour, and may possibly be a variety, but the sheath of the 

 ovipositor is distinctly shorter, being scarcely more than 

 one-quarter of the length of the abdomen, and the enclosed 

 area on the median segment is a little broader and distinctly 

 rhomboidal. The pubescence on the dorsal surface of the 

 median segment and the sides of the scutellum is much 

 shorter and more sparse. The antennae are 37-jointed. 



Hab. Thursday Island, Queensland (Turner), May 1902. 



In all Australian species of the genus here described the 

 radius beyond the second transverse cubital nervure and also 

 that nervure itself are only indicated, not fully developed as 

 in the European C. saltator, Fabr. This condition, however, 

 appears to be common in the genus, C, saltator seeming to 

 be rather exceptional.
