Corcym cephalonica Stn. 



This moth first came to my attention when Mr. J. Kotinsky 

 found it breeding in a feed warehouse in Honolulu in July, 

 1908. Later, I caught a specimen in my house in Kaimuki, 

 January 10th, 1909. The latter part of January of this year, 

 the moths were found emerging from the remnants of a package 

 of cracked wheat obtained from some Honolulu grocery store 

 sonle time previously. From these specimens, I have determ- 

 ined it as Corcyra cephalonica Stn., a European moth, appar- 

 ently not yet recorded in the United States, though it certainly 

 must occur there from whence it has reached Honolulu.

A Leaf-Mining Proterhinus. 



BY OTTO H. SWEZEY. 



While on a collecting trip up Mt. Olympus, Oahu, February 

 11, 1912, I observed that the leaves of Broussaisia arguta were 

 very extensively mined. Examining some of these, I w^as sur- 

 prised to find in the mines larvae of some beetle, footless grubs 

 of the Curculionid type. Examining the tree further, I found 

 adult beetles of the genus Proterhinus very abundant at the tips 

 of growing shoots, feeding on the buds and young leaves, between 

 the latter where they are close together previously to their un- 

 folding in the growth and development of the shoot. Many of 

 the larvae found appeared to be full-gro^vn. i^o pupae were 

 found. I did not succeed in rearing any adults from the larvae 

 collected. They all died a few days after they were brought 

 down from the mountains. However it is beyond a doubt -that 

 the larvae found in the mines in the leaves belong to the species 

 of Proterhinus whose adults were so numerously feeding on the 

 same tree. Dr. Perkins has kindly determined the species as 

 excrucians P., a very variable species which has been abund-
