Briichid in palm seeds. — Mr. Ehrhorn exhibited a Bruchid 

 found in a shipment of palm seeds from Cuba. A Chalcid 

 had emerged in numbers from the shipment and observations 

 by Mr. Fullaway indicated it to be a parasite attacking the 

 Bruchid eggs but emerging from the pupae. If satisfied of 

 its parasitic habit on Bruchids, the parasite will be released 

 here. 



Clirysidid. — Mr. Mant exhibited several specimens of a 

 Chrysidid captured at his residence in Manoa. It was an 

 undetermined species wliich has only lately made its appear- 

 ance here, the first specimen having been collected in June, 

 1914, by ]\[r. Potter. 



Chrysomyza aen-ea. — Mr. Eullaway reported finding a mass 

 or the larvae of this Ortalid breeding in horse and cow manure 

 at Waialae, about 50% of which proved to be parasitized by 

 S-palangia. 



Telcspiza idtima. — Professor Bryan reported this as a new- 

 species of bird from !N^ihoe or Bird Island, taken by Captain 

 Brown of the '^Thetis." The description will be in a forth- 

 coming nund)er of the "Auk." 



Chinese tlirush. — Professor Bryan reported that he was 

 trying some feeding experiments on the Chinese thrush. A 

 nest had been upturned, the three nestlings found were placed 

 in a rat trap in which the mother bird was captured later. 

 In this connection, Mr. Ehrhorn mentioned that dried water 

 boatmen was the favorite bird-food used by the Chinese bird 

 men on vessels. 



Coconut leaf-roller [Omoides hlachhurni (BidLJl de- 

 stroyed by ants. — Professor Illingworth reported that these 

 moths began depositing eggs on his coconut trees in Palolo 

 Valley, March 16, 1915, and continued to the present (May 

 6, 1915), but none of the caterpillars had been able to resist 

 the attacks of the ants (Pheidol-e megacepJiala) long enough 

 to pupate. A few of the larvae reached almost full size, 

 but they had to finally succumb. The ants were first observed, 

 actually at work, destroying a young colony, on April 14th 

 last. They first cut away the under-part of the web, that 

 protects the caterpillars, and then pulled them out. In a 

 number of cases they were seen eating the egg-masses, and
