336 MR. R. K. TURNER ON THE [Feb. 15, 



Second and third joints of the flagellum of about equal length. 

 Pronotum depressed anteriorly, the posterior margin broadly 

 arched. Median segment obliquely sloped posteriorly, the dorsal 

 surface before the oblique slope about twice as broad as long. 

 Anterior tarsi with a few short spines ; posterior tibiae spinose ; 

 tarsal ungues with one tooth. Second abscissa of the radius as 

 long as the first, the two recurrent nervures received far apart 

 near the base and apex of the second cubital cell, radial cell rather 

 broad. Cubitus of hind wing originating far beyond the trans- 

 verse median nervure. Transverse median nervure of fore wing 

 joining the median nervure before the origin of the basal nervure. 



Black, with cinereous pubescence on theclypeus, front, anterior 

 angles and posterior slope of the median segment, and a broad 

 transverse band on the apical margin of each of the four basal 

 abdominal segments. Wings hyaline, with a narrow fuscous 

 band crossing the wing at the basal nervure and another broad 

 band from the radial cell ; hind wing pale fuscous at the apex. 



Length 9 mm. 



Hob. Mackay, Q. {Turner). October. 



Very near A. immitis, but differs considerably in neur-ation 

 and in the colour of the wings. 



Aporus tenellus, sp. n. 



$ . Mandibles bidentate ; clypeus rather more than twice as 

 broad as long, transverse on the anterior margin. Eyes nearly 

 parallel, slightly converging towards the vertex ; the ocelli in a 

 broad triangle, the posterior pair further from each other than 

 from the eyes. Head smooth and slightly shining. The antenna? 

 scarcely as long as thorax and median segment combined ; the 

 second joint of the flagellum no longer than the third. Pronotum 

 about twice as broad as long, not depressed anteriorly. Median 

 segment a little longer than broad, the posterior slope steep but 

 not abrupt, the posterior angles very feebly produced. Abdomen 

 subsessile, slender, a little compressed laterally, the apical 

 segment very narrowly rounded at the apex. Anterior tarsi 

 without a comb, posterior tibiae spinose. Second cubital cell 

 pointed on the radial nervure, the distance between the recurrent 

 nervures a little greater than their distance from the base and 

 apex of the second cubital cell. Cubitus of the hind wing 

 originating a little beyond the transverse cubital nervure. 

 Transverse median nervure of fore wing received a little beyond 

 the basal nervure. 



Black, with greyish- white pubescence as follows : on the clypeus, 

 front, margins of the pronotum narrowly, a transverse line on the 

 mesonotum, two spots on the scutellum, the postscutellum, pleurae, 

 a large spot at each angle, anterior and posterior, of the median 

 segment, a spot at the base of the first dorsal abdominal segment, 

 and a broad transverse band, narrowly interrupted in the middle, 

 on the apical margin of the four basal segments. Wings very 

 pale fusco-hyaline, rather darker on the apical third of the fore
