The same can he said for th,e <Teiius Opogona. Ahout two 

 dozen species are known, l)ut the hahits of only a few of them are 

 known. In Java, caterpillars of dimidiatclhf' feed on sugar 

 cane, eating the surface of the young roots at the hase, causing 

 them to die. They also sometimes enter the passages of the 

 borers; but chiefly live on dead tissues: hence, are not particularly 

 injurious, especially as they are not numerous. In Xew Guinea, 

 saccharella has similar habits to the above. In Java, fit in ice ps* 

 is reported as feeding on the coconut palms. In Mauritius. 

 siihccri'iiwlUi '' is rejjorted to feed on sugar cane, potatoes, and 

 other stored tubers. The larva of laclnmitis*' was found feed- 

 ing in the fungus beds of the common termite, in Cevlon. Our 

 two species both feed in dead sugar cane, rotten wood, and vari- 

 ous other decaying substances. 



I have included four species of motlis sent i)y Mr. ^luir from 

 New (iuinea. where their larvae feed in cane similarh- to the wav 

 that some of our species do here. Of these moths, two species 

 are Erciiiictis (both nevv' species), and two are Opogona (one new 

 species). I have included themi, as it is a matter of considerable 

 interest to know that elsev/here some of the species of these two 

 genera have the same habits that the Hawaiian species have. I 

 have no doubt Intt that when the hahits of those species of these 

 genera whose habits are at present unknown, are studied, they 

 will be found to be quite similar to those already known. 



Habits of the other genera herein treated are mostly as little 

 known. Cryptoblabcs has about a dozen species. Of these, in 

 Europe, the larva of bistriga' feeds in folded leaves of oak and 

 alder. I have found nothing puljlished in regard to haliits of 

 other sjiecies. 



Of Batrachcdra, more is known, for discussion of v^hich see 

 under B. rilcyi, page 23 of this bulletin. 



There is very little j^arasitization of anv of these species of 

 moths so far as I have been able to observe. Probably of the 

 few treated of in this paper none are of anv special importance, 

 tho one or two of them were found locallv (|uite alnmdaiU at 

 one time on the bud worm, yet there was no a]:)precial)le diminu- 

 tion in their numbers.
