Described from seven specimens (tyi)e S ) reared from 

 larvae feeding in live wood of Coprosma longifoJia at Malama- 

 lama, a ridge on the windward slope of ]\It, Konalinanui, 

 Oalni, October 8, 1916 (Swezey). 



The larvae of this genus are elongate and Avhitish and 

 itsually feed in dead wood; but the larvae of this species were 

 found in the live wood and were quite abundant in the trees 

 of the locality. The injury b}^ them caused dead places in the 

 tree trunks and branches, and a very rough, giiarlly appearance 

 where the growing of the tree had partially overgrown the 

 injuries. Pieces of branches containing larvae were brought 

 in, and the moths issued November 20 to December 14. A 

 series of 18 Sderodcrmvs semnoprepiae Bridwell also issued 

 from this material, and cutting up some of the wood, it was
