between segments are yen* shallow, giving the caterpillar a very 

 smooth surface. 



Pupa. — 12 mm. pale brown with greenish tinge especially in 

 thoracic region, a greener median line on dorsum of al)donR'n, 

 eyes darker; Aving-cases extending to apex of 4th abdominal 

 segment, apical point a little further, antenna- and leg-cases 

 extend a little beyond apex of oth a])dominal segment, free beyond 

 4th segment; cremaster short, l)lunt, with 8 hooked spines 

 fastened into the cocoon. The cocoon is slight and made in the 

 retreat where the caterpillar lived. Pupation takes place in 2 to 

 4 days after the cocoon is startc(l. Larval period 20 to 22 days; 

 pupal period 10 to 11 days. 



Omiodes monogramma Meyr. (Plate II, tig. 9). 



" (?' . 25-29 mm. Head and palpi deep ferruginous, lower half of 

 palpi white. Thorax ferruginous, posteriorly paler and mixed with 

 whitish-ochreous. Abdomen ferruginous-ochreous, segmental margins 

 usually finely white. Forewings moderate, termen gently bowed; ferru- 

 ginous; costa sufifused with dark fuscous from base to f ; second line 

 about i, almost straight, white, obsolete on costa, posteriorly edged with 

 fuscous sufifusion; a dark fuscous terminal line; cilia grey, with darker 

 sub-basal line. Hindwings fuscous, usually suffused with dull ochreous 

 towards dorsum; a white postmedian line, Obtusely angulated near 

 tornus, posteriorly edged with dark fuscous suffusion, beyond which the 

 terminal area is wholly ferruginous-ochreous; a dark fuscous terminal 

 line; ciali whitish, with dark grey sub-basal line, 



Allied to O. deniaratalis, but differs by the larger size, ferruginous 

 colouring, absence of orbicular and discal dots, second line of forewings 

 placed nearer termen, and postmedian line or hindwings obtusely an- 

 gulated and followed by dark fuscous suffusion." [Meyrick, Fauna 

 Hawaiiensis, I, Pt. II, p. 205, 1899.] 



Tlie females have less fuscous suffusion than descril)eil above 

 for the males. Sometimes these are faint fuscous orbicular and 

 discal dots in forewdngs, and a faint discal dot in hindwings. 



This species is common locally in the mountains of Kauai, 

 Oahu, and Hawaii. Its distribution is restricted to the regions 

 where its food plant grows, as the caterpillars apparently feed 

 upon but on(» species of plant, a native Liliaceous plant {Dianella 

 odorata.) The caterpillars feed inside a leaf folded together along 

 the mid ril), so that the margins come together above. The
