HJii/parohia ntadcrar. — Professor Illiiii;\vortli stated that 

 yonriij; of this roach Avhieh he had under observation had com- 

 ])lcted their life eyele in !) montlis and 15 days. 



Eleuthci-oda dijtiscoidrs. — The hahits of this roaeh were 

 discussed. ^Ir. Osboni I'eported havinc; been shown a grove 

 of algaroba trees at ]\Iaka\veli, Kauai, in wliicli a hirge num- 

 ber of the trees within an ai'ea of al)out 25 acres had had 

 the bark scraped oif from the upper liml)s and portions of 

 the harger branches so that there was considerable dead tim- 

 ber. The appearance of the scraped limbs was very similar 

 to the cypress twigs that have been killed by this roach having 

 eaten off the bark, and it may be that it has also been injuring 

 the algaroba in the same way. Mr. Kuhns reported having ob- 

 served similar injury to algaroba trees at Waianae. Mr. Illing- 

 worth statetd that he had often seen this roach very abundant 

 about the base of algaroba trees.

 tended at Berkeley, Cal., early in August.

 cosmopolitan moth which he had captured flying about in his 

 cabin on board the steamer ''Sonoma," when three days out of 

 San Francisco. The incident illustrates how readily such in- 

 sects may effect their introduction to Hawaii. 



Catorama mexicana. — Professor Illingworth called atten-
