free from them, and again others with but one species at most 

 preying upon them. 



A striking feature of Hawaiian Lepirloptera is the ahnost 

 complete absence of gregarous feeding in the caterpillars. Per- 

 haps there are none strictly gregarious, but some, as the cocoa- 

 nut leaf roller {Omiodes hlackburni), are gregarious when quite 

 young. Another feature is that the greater number of the 

 species are hidden feeders either in rolled or spun-together 

 leaves, in cases, in silken galleries in trash, in stems of living- 

 plants, or in dead stems and rotten wood. They have not com- 

 plete protection, however, as special parasites have become dev- 

 eloped to reach them in their hiding places. 



In this papei-, an attempt is made to give the feeding habits 

 of all species so. far as known or previously recorded. The 

 authority is given whore the observation is not my own. In- 

 troduced species are included along with the others. The order 

 of families taken up is the same as that given in the ^'Fauna 

 Hawaiiensis," and the nomenclature there given is followed. 



There are quite a number of genera, some of them large 

 ones, of which as yet the larvae are entirely unknowai. On the 

 other hand, for a few of the large genera, I have discovered the 

 larvse and food-plants of a majority of the species. At the 

 present time there are some T70 odd known species of Lepidop- 

 tera in the HaAvaiian islands, and as will be seen by this paper, 

 something is known of the habits of nearly one-fourth of these 

 species. 



Caeadrixidae. 



Leucania euclldias Meyr. — The caterpillars of this variable 

 species feed on various species of ferns, particularly on Acrosti- 

 cJnnn spp., and Aspidium cyatheoides,, though on a number of 

 others as well. L. pyrrhias Meyr. — The caterpillars feed chief- 

 ly on sedges, particularly Baumea meyenii, also on grasses, and 

 sugar cane. L. amhJycasis Meyr.— Grasses and sugar cane. L. 

 vuipuncta Haw. — The cosmopolitan army worm, feeds on 

 grasses, cereals and sugar cane. 



Ar/rotis ypa'don Rott. — Cosmopolitan, feeds on garden and 

 farm crops, sugar cane and weeds. A saucia Hub. — Cosmopo-
