on akebi and also on hiragi-nanten (Berberis bealei Fort.), and 

 that the imago appears from the end of August to December. 

 As I have taken the larva at Yoshino, Yamato, in May, the young 

 larvae possibly hibernate. 



Local distribution. — Honshu. Koya-san, Kishu Province, Aug- 

 ust, September; Yoshino, Yamato Province, June; Kobe, Settsu 

 Province, October to December. Hokkaido ( Yezo) . Hakodate, 

 Oshima Province, September. 



Cocoon. — The larva spins a loosely webbed cocoon among the 

 leaves of the food plant. 



Matsumura ^^ states that the imago causes injury to such fruits 

 as pears, peaches, etc., by sucking their juices. The following, 

 references to this habit alluded to in the Zoological Record and 

 elsewhere are of much interest:" 



The proboscis of Ophideres is modified into a strong, rigid, boring 

 instrument, armed with spines, with which the insect pierces the skin of 

 oranges and sucks the juice. [The proboscis of 0. fullonica L. is figured.] 



Ophideres fullonica and its allies do not perforate oranges, etc., but 

 enlarge the hole previously made by some other insect and suck the juice 

 through that." 



The structure of the proboscis of 0. fullonica is also described, 

 with figures, by F. Darwin.^*
