3. List o£ Lepidoptera collected by Mr. H. O. Forbes in 

 the Islands of Timor Laut, By Arthur G. Butler, 

 F.L.S., F.Z.S., &c. 



[Eeceived AprQ 30, 1883.] 

 (Plate XXXVIII.) 



Twenty-three species of Lepidoptera were obtained by Mr. Forbes 

 in his recent expedition to Timor Laut ; one of these, however, is 

 apparently a Micro-Lepidopteron, so much rubbed and broken as to 

 be unrecognizable ; all the Moths, in fact, are in very poor condi- 

 tion, forming a marked contrast in this respect to the Butterflies, 

 which are well preserved.
