This is a very common grass in the mountains, and its leaves 

 are usually foimd extensively mined by the larvae of this moth. 

 In the Waianae Mountains I once found a larva mining a leaf 

 of another grass (Panicum nephelophilum) growing in the 

 vicinity of plismenus. The mine is usually lengthwise in the 

 leaf, widening as the larva has grown in size. 



The full-grown larva is about 5 mm. in length, pale green 

 with a mid-dorsal purplish-red stripe, also some more or less 

 lateral mottlings of the same color, especially anteriorly; head 

 green, sutures, lateral edges and mouth-parts brown, eyes black ; 

 head retracted into second segment which is wider than follow^- 

 ing segments, green with some blackish dots on sides and pos- 

 terior part; hairs pale. When full-gTown, the larva emerges 

 from the leaf, spins a few libers beside the mid-rib' of the leaf, 

 at the base, or in some other partially secluded place ; then pu- 

 pates among these fibers without making a cocoon. 



The pupa is about 4 mm. in length, pale yellowish, with sev- 

 eral fuscous streaks ventrally, also two pairs of conspicuous 

 blackish spots, eyes reddish brown ; head with a compressed tri- 

 angularly pointed projection in front, a large lateral projection 

 behind each eye with sharp point directed anteriorly ; thorax 

 with low median dorsal ridge; abdomen with broad lateral 

 flange on each side just on the line of spiracles so that the latter 

 are just beneath its outer edge, no dorsal median ridge; setae 

 "iii" are situated on upper surface of this flange, they as well 

 as setae "i" and "'ii" are quite long and stout and hooked into 

 silk which the larva has spun on the surface of leaf; setae "i" 

 and "ii" in a straight line ; cremaster bilobed, a number of 

 hooked bristles fastened into the silk by which pupa is suspend- 

 ed, dorsal side towards leaf; antenna-sheaths extend to apex of 

 abdomen, wing-sheaths almost as far, not roughened with minute 

 points as in the Ipomoea species. Pupa stage occupies 8 days.
