604 DESCRIPTION OF A NEW SPECIES OF lODIS. 



greenish - white. Hind wings as forewings, hindmarginal line 

 yellow-green ; hindmargin slightly angled at vein 4 : cilia 

 greenish- white. Undersurface of wings greenish-white. 



The light pea-green colour, absence of markings, and the 

 yellow-green borders of wings readily distinguish this species. 

 It comes near to TJrolitha hipiinctiferay Walk., but appears to 

 be a true lodis. 



PostscrijJt. — Since writing the above, I find that the tree on 

 which these caterpillars feed is Duboisia myojwroides. Dr. 

 Thomas L. Bancroft found the exuvia of a caterpillar, probably a 

 larger species, among a quantity of collected leaves. It contained 

 the active poison principle duboisin. Caterpillar elongated, flat- 

 tened, green with lighter green and darker green linear stripes 

 laterally. 



In the Proceedings of this Society for 1887, (p. 1016, 

 pi. XXXIX.), Mr. Olliff described and figured a moth of the 

 genus Pielus belonging to Mr. Prince. I happened to be present 

 at the meeting at which the specimen was exhibited, and stated 

 that I possessed three specimens from the Gippsland District. 

 I had sent an example to Mr. Meyrick, who afterwards re- 

 turned it named P. hyalinatus. On referring to Schafler's 

 LejndopL Exot. Nov. Ser. i, fig. 50, I find an almost exact 

 coloured copy of PI. xxxix. of P.L.S. N.S.W., and the insect 

 named P. hycdinatus. Walker also described it under the name 

 P. hyalifiatus, and referred to Schaflfer; hence Mr. OllifF's name 

 P. impericdis must give way to P. hyalinatus. 



I have a specimen I take to be the ^. It is 75 mm., and is 

 marked similarly to the larger ones, bat the two apical spots 

 alone of the oblique row of spots parallel with the hindmargin of 

 the forewings are silvered.
