314 MR. R. E. TURNER ON THE [Feb. 15, 



by a distance about equal to the length of the first and second 

 joints of the fiagellum combined, and by almost the same distance 

 on the clypeus ; the second joint of the fiagellum more than half 

 as long again as the first. Pronotum not much narrowed ante- 

 riorly, its posterior margin arched. Median segment finely 

 transversely striated, convexly declivous, broader than long, with 

 a longitudinal median sulcus. Abdomen subpetiolate, the first 

 segment shorter than the second, narrowed at the base, but 

 without a distinct petiole. Pruinose and subopaque. 



Black, with short silver pile on the clypeus, lace, pleura?, and 

 coxse. Wings hyaline, with a very narrow fuscous band along 

 the basal nervure of the fore wing, another much broader half 

 crossing the wing from the base of the radial cell, the apex of both 

 wings slightly clouded with fuscous. Second abscissa of the 

 radius nearly equal to the third, second transverse cubital nervure 

 short, the radial cell very broad. Cubitus of the hind wing- 

 originating just before the transverse median nervure. 



Length 13 mm. 



Hob. Mackay, Q. (Turner). 



Very near callisto Sm. from Aru, but differs in the absence of 

 a distinct petiole to the first segment of the abdomen, in the 

 sculpture of the median segment, the greater distance between 

 the eyes on the vertex, the short second transverse cubital nervure, 

 and the point of origin of the cubitus of the hind wing, which in 

 callisto is just beyond the transverse median nervure. The Indian 

 species identified as callisto by Colonel Bingham is intermediate 

 in the form of the petiole, but differs both from callisto and 

 dispersa in the form of the median segment which is slender and 

 much longer than broad. P. erigone Bingh. is really nearer to 

 the present species than his callisto. The difference in the point 

 of origin of the cubitus of the hind wing is interesting as showing 

 the slight systematic importance that can be attached to a 

 character largely used by both Kohl and Ashmead in their classi- 

 fications of the family.

Hah. Mackay to Cooktown, Q. (Turner). 



This species is very near the last, but has the antenna? yellow, 

 and differs in the neuration and in the form of the clypeus. The 

 submedian cell of the fore wing is very much longer than the 

 median, the third abscissa of the radius half as long again as the 

 second, the cubitus of the hind wing originates beyond the trans- 

 verse median nervure. 



Pseudagenia australis Cam.

This species has the second abscissa of the radius scarcely more 



than half as long as the third. My specimens are from Victoria. 



I doubt if it is more than a geographical race of fasciata Fabr.
