TJianaos and referred to the value of the genitalia as characters 

 for specific separation. 



Mr. Rehn exhibited the type specimens of three species of 

 Argentine Orthoptera which also represent three previously un- 

 known genera. The first, a walking stick, belongs to a group 

 of genera peculiar to Paraguay and the adjacent portion of 

 northern Argentina. The second, a member of the Acridid sub- 

 family Owvmexechinae, is a most interesting annectant type as 

 it connects in numerous characters two heretofore rather wide- 

 ly separated sections of the sub-family. The third genus is a 

 very remarkable katydid type more nearly related to the genus 

 Insara than to anything else. The latter genus reaches its 

 greatest development in Central America and it seems doubt- 

 ful that several species recorded from South America and as- 

 signed to the genus really belong there. The collection of 

 which the new genera form part was made by Mr. P. Jorgensen 

 and the study of the same developed the fact that fifty-six of 

 the total of one hundred and sixty-two species had not previ- 

 ously been recorded from Argentina. The major portion of 

 the series was from the northeastern territory of the Missiones, 

 which is the most tropical portion of the country, the majority 

 of the species found there being Brazilian types. 



Mr. Hornig said he had collected cocoons of Callosamia 

 angulifera suspended by silk from the twigs of the tulip tree 

 and exhibited a suspended cocoon which he thought was anguli- 

 fera. 



Dr. Calvert referred to studies of the honey bee made by Dr. 

 D. B. Casteel, in which he had corrected erroneous ideas as to 

 the physiology of parts of the legs of these insects.
