548 LEPIDOPTERA OF EBOK SCRUB, N.S.W., 



however, find more than two species common to the two locali- 

 ties. One species of Gelechianae, which is a doubtful member 

 of the fauna, as I may have taken it at the edge of the scrub, 

 and the species of Heliodininae, which is allied to Stathmo- 

 poda, I shall not describe at present ; but the others will be 

 dealt with here. The types are in my collection. I hope to 

 be able to revisit this interesting and productive locality, and 

 make further additions to its lepidopterous fauna. My cap- 

 tures were made on January 7th, 9th, and 11th, 1914.

 Subfam. Lithosian^. 

 Gen. Trissobrocha, nov. 

 rpLcrcro/Spo^os, with threefold noose. 

 Frons smooth. Tongue developed. Palpi moderate, re- 

 curved, ascending, slender, smooth-scaled ; terminal joint 

 about half second, acute. Antennae of cf simple, slightly 

 laminate towards apex, moderately ciliated. Thorax smooth 

 above and beneath. Posterior tibiae with two pairs of long 

 spurs. Forewings with all veins present in both sexes, 2 from 

 |, 3 from before angle, 4 from angle, 7, 8, 9 stalked, 9 arising 

 before 7, 10 from before angle, well separated at origin from 

 7, 8, 9, 11 free. Hindwings with all veins present, 3 and 4 

 connate, 5 from below middle of discocellulars, curved toward 

 4 at origin, 6 and 7 stalked, 8 from cell at J.

 that genus, vein 5 is absent in cT (but not in 9)j ^^^ 1^ i^ 

 from a point with 7, 8, 9.
