PORTHESIA, Stcph. 



G. Portliesia aliena, n. s. 

 Primaries sericeous snow-white ; costal margin towards the base 

 golden brown ; secondaries white, the veins broadly suffused with 

 pale testaceou.s, giving the wings a creamy tint ; thorax white, 

 antennae with pale brown pectinations ; abdomen, excepting at 

 base, yellowish barred with black ; anal tuft ochreous ; wings below 

 white, slightly yellowish at the borders ; basal half of costal border 

 of primaries dark brown ; pectus white ; palpi and front of anterior 

 legs ochreous, legs otherwise cream-coloured ; venter ochreous. 

 Expanse of wings, 30 mm. 



Peak Downs. 



Allied to P. similis of Europe. 



Leptocneria, n. g. 



Most nearly allied to Ocneria of Europe (0. rubra), but differing 

 as follows : — Prinaaries comj)aratively longer, with more oblique 

 and less regularly convex outer margin ; costal vein extending to 

 about the second-third of costa ; subcostal with five branches, the 

 first branch emitted considerably before the end of the cell and 

 alxnost uniting with the second branch at some distance beyond the 

 cell ; second branch emitted from the anterior angle of the cell, 

 extending to the apex and throwing off the fom-th and fifth 

 branches from its inferior edge ; the fifth branch is emitted at some 

 distance beyond the cell and opposite to the point where the first 

 and second branches almost unite ; the foui-th branch is emitted 

 much nearer to outer margin ; the radials are emitted fi'om opposite 

 . angles of the cell, the lower radial (as in Ocneria) forming a fourth 

 median branch ; disco-cellular concave ; median branches almost 

 as in Ocneria ; secondaries with the costal margin convex and the 

 subcostal branches emitted from a footstalk; otherwise as in 

 Ocneria ; woolly frontal tuft longer ; palpi much longer and less 

 hairy ; tibial spines of hind legs nearer together ; antennas more 

 strongly pectinated. 



7. Leptocneria hinotata, n. s. 

 Whitish grey ; primaries with a dusky -margined white spot just 

 beyond the middle of the cell, and a second reniform spot at the 

 end of the cell ; these spots are enclosed between the two usual 

 stripes, which are grey, a httle darker than the ground colour 

 inner stripe sUghtly u-regular, dentated, outer stripe dentate-sinuate,
