Hab. — One specimen, Mt. Olympus, Oahn, January 12th, 

 1919 (Sweaey), bred from mine in leaf of Pelea sandwicensis. 

 The mine of this species is chiefly found in P. sandzviccnsis, 

 but has also been found in P. rotitndifolia and some undeter- 

 mined species of Pclca. I have found these mines at the 

 following ridges on Oahu : Waialae, Palolo, IVIt. Olympus, 

 Wahiawa and Punaluu, and also on Kauai. The mine of this 

 species is shown in Fig. E. It is at first a thread-like mine 

 with numerous longitudinal somewhat parallel loops nearly the 

 length of the leaf and somewhat curved with the concavity 

 towards the margin, the enclosed area eventually becoming a 

 large blotch mine. The whole mine is usually situated on one 

 side of the midrib and occupying nearly that whole half of 

 the leaf. 



Opostega sp. 



Figure F shows a mine found in leaves of several difl^erent 

 species of Pelea (anisata, kaiiaiensis and gayana) at Kaholua- 

 mano, Kauai (J. A. KiischeJ. It is an irregular tangle, grad- 

 ually enlarging as the larva increases in size. No moths have 

 been reared from these mines yet. It would be another new 

 species, unless perchance it were the beautiful species dives, 

 described in the "Fauna Hawaiiensis," two specimens of which 

 were collected at Halemanu. Kauai. 



These interesting little moths need much further study here 

 in Hawaii. In a paper on the Lepidopterous Genus Opostega 

 and its larval Affinities ( Proc. Ent. Soc. Wash., 20:27-38, 1918), 

 Carl Heinrich figures the head structure and mouth parts of 

 the larva of one of the Hawaiian species of Opostega from 

 material which I had collected. He makes use of this to show 

 affilnities of Opostega and Opostegidae to the families Nepticu-
