Rhyparobia maderae.- — Professor Illingworth stated that 

 young of this roach which he had under observation had com- 

 pleted their life cycle in 9 months and 15 days. 



Eleidheroda dytiscoides. — The habits of this roach were 

 discussed. Mr. Osborn reported having been shown a grove 

 of algaroba trees at Makaweli, Kauai, in which a large num- 

 ber of the trees within an area of about 25 acres had had 

 the bark scraped off from the upper limbs and portions of 

 the larger 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. 



Mr. Swezey and Mr. Ehrhorn reported briefly on the meet- 

 ings of the Entomological Society of America and American 

 Association of Economic Entomologists, which they had at- 

 tended at Berkeley, Cal., early in August.

Agroiis ypsilon. — Mr. Giffard exhibited a specimen of this 

 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- 

 tion to the ease with which this beetle is distributed thru 

 commerce. He had recently found specimens in a tightly 

 sealed tin of chocolate from ]^ew York. 



Crater Lake insects. — Mr. Swezey exhibited a collection
