in front; palpi fuscous, ochreous telow; tongue and tips of maxillary 

 palpi fulvous; legs ochreous, femora and fore tibiae with some fus- 

 cous. Forewings dark fuscous with some ochreous scales mixed in, 

 more abundant on costa, and a few scattered ferruginous scales, more 

 abundant at base, veins ochreous; first line ochreous, angled outward- 

 ly about middle making nearly a right angle, posteriorly heavily mar- 

 gined with dark fuscous; a more or less obscure dark fuscous orbi- 

 cular dot; an ochreous discal spot traversed by a transverse black 

 spot; second line ochreous, angled outwardly below costa and again 

 below middle, margined anteriorly with dark fuscous; a series of 

 terminal black spots between the veins; cilia pale fuscous, darker 

 at base. Hindwings slightly paler fuscous than forewings, a dark 

 fuscous discal dot, an ochreous post-median line anteriorly dark fus- 

 cous margined, angled outwardly below middle; a dark fuscous line 

 on termen, cilia as in forewings. 



The color pattern of this species is very similar to that of O. 

 blockbunii and 0. meyricki; but in this the dark fuscotis pre- 

 dominates, while in blackburm ochreous predominates, and fer- 

 ruginous predominates in meyricki. The angulation of the first 

 line of forewings is nearly a right angle in mnsicola, while in 

 the other two mentioned species it is an acute angle. The angu- 

 lation of second line below middle is less acute in this species 

 than in the other two. 



In August, 1908, I discovered numerous caterpillars of all 

 sizes, also eggs, on wild bananas high up in lao Valley and at 

 Nahiku, Maui. These caterpillars were dififerent from any 

 Omiodcs caterpillars I had yet seen, and on rearing, proved to 

 be different from any previously 'described species; hence, I am 

 describing it as new. 



The egg-masses were found on the under side of the leaf 

 mostly along the midrib, but also on the surface away from the 

 midrib. The eggs were similar to those of other species of 

 Omiodcs, and about as many in a mass as in those of 0. black- 

 biirni. 



Full-grown larva about .27 mm. ; dull pale greenish ; head 

 testaceous with some light brownish checkering on upper part, 

 a round black spot in each lobe in front, two oblique short black 

 lines on paraclypeus, eyes black with a dark brown streak ex- 

 tending upward from them, a short black line on posterior mar- 

 gin of head extending upward from a black dot at postero- 

 ventral angle ; cervical shield with black lateral margins, anterior 

 margin slightly fuscous and with a row of ten dark fuscous 

 dots, a large broad elongate longitudinal black bar in each lateral 

 lobe, on the dorsum between these and near the posterior margin 

 are two groups of five tiny dark fuscous dots ; tubercle in front 

 of spiracle with a black line on dorsal margin ; tubercles ii on
