Some thirty species of Australian Odynerus, or closely allied 

 forms, were exhibited, showing the great variety of appearance 

 and bright colours as compared with the remarkably general 

 Muchness of the Hawaiian species. The variety of structure 

 was also large. A few typical Odynems of other countries 

 were also exhibited, and Dr. Perkins remarked on the necessity 

 of the study of exotics ; with the study of a few Prosopis and 

 Odynerus one knows all the Hawaiian species. 



In a discussion on the habits of aculeate Hymenoptera, Dr. 

 Perkins, in reply to Dr. Cobb, stated that the caterpillars, 

 stored up for the food of the larvae, were put through a process 

 of stinging and malaxation. Dr. Cobb had never observed the 

 caterpillars to be dead or even injured. Mr. Swezey stated 

 that sometimes the caterpillars are so insufficiently paralized 

 as to pupate, and even crawl about after being stung. The larva 

 of the bee is hung up in the cell and feeds by descending onto 

 the caterpillar. 



Dr. Cobb observed that the drawing of insects was more 

 desirable when from living specimens. He had found that he 

 could paralyze them by means of bee stings ; while a wasp's 

 sting would kill an insect, the Odynerus sting would only 

 paralyze. He had produced paralysis in Diptera by either 

 inserting the bee sting poison on the point of a needle in the 

 neighborhood of the thoracic ganglia or by presenting the same 

 parts of the specimen to the bee-sting directly. An insect so 

 stung retained its natural color and position ideally for draw- 

 ing. 



Mr. Swezey stated that he never was severely stung by 

 Odynerus in all his handling of them. 



Mr. Giffard exhibited specimens and presented the following 

 notes : 



1. Calandra (?) sp. (Introduced) 1 specimen. 



Taken on October 14, 1906, from the base of a new pseudo- 

 bulb of Phalaenopsis amabiUs imported from the Philippine 

 Islands during month of October. Larva of above also seen 

 in the same plant. 



2. Calandra remota (Hawaiian) 6 specimens. 



Taken on October 20, 1906, at 1000 feet elevation on Tanta- 

 lus in decaying stems of banana {Musa cavendishii). 20 

 specimens in all taken. 



3. Brachypeplus guttatus (Hawaiian) 6 specimens. 

 Taken on October 1 of 1906 at 1300 feet elevation on
