68 MR. R. E. TURNER ON 



Antenn* fairly stout, but not short ; second joint of the flagellum 

 as long as the first and third combined, the third fully half as 

 long again as the fourth. Eyes slightly diverging towards the 

 clypeus ; posterior ocelli a little further from the eyes than from 

 each other. Thorax subopaque, finely aciculate ; scutellum tri- 

 angular very narrowly rounded at the apex. Median segment 

 short, opaque, with a deep median sulcus. Abdomen sub- 

 opaque ; first dorsal segment as broad as the second, the three 

 amcal segments strongly compressed laterally, the dorsal surface 

 of the sixth segment almost linear; second ventral segment 

 with a distinct, but not very strong, transverse groove near the 

 base. Hind tibia? spinose, the spines short; calcana white, 

 black at the extreme apex. Second abscissa of the radius 

 distinctly longer than the third; first recurrent nervure 

 received at three-fifths from the base of the second cubital 

 cell second at two-fifths from the base of the third cubital 

 cell! Cubitus of the hind wing originating just before the 

 transverse median nervure, almost interstitial.

This is somewhat allied to C. lunatus Sm., but is easily 

 distinguished by the different proportions of the joints of the 

 flagellum, by the difference in the yellow marks on the tore 

 wings, by the more triangular scutellum, and most conspicuously 

 by the strongly compressed anal segments.

SlEROLA LEEUWINENSIS, Sp. n. 



5. Nigra, antennis pedibusque testaceo - ferrugineis ; alis 

 hyalinis; venis ferrugineis, basi testaceis ; capite magno, 

 latitudine duplo latiore. 



Long. 3 mm. 



5 . Head very large, flat, twice as long as broad, longer than 

 the antennas. Eyes large, oval, separated from the posterior 

 margin of the head by a distance at least equal to their own 

 length ; ocelli situated close to the posterior margin of the head, 

 far behind the eyes. Head, thorax, and median segment coria- 

 ceous, abdomen smooth and shining : the pronotum broader than 

 long, a little narrowed anteriorly ; mesonotum short, with a 

 distinct longitudinal furrow on each side ; a distinct transverse 

 groove at the base of the scutellum ; median segment margined 

 at the sides, with an obscure median carina. Fore wing with a 

 prostigma and a closed discoidal and radial cell as in other species 

 of the genus. 



Hob. Yallingup, S.W. Australia ; December. 



This is distinct from the two Australian species described by 

 Ashmead, having a carina on the median segment and a furrow 

 on each side of the mesonotum.
