Philadelphia. 



Meeting of January 23, 1919. Five persons present, Director Philip 

 Laurent presiding. 



Mr. Robert Lee Haines, Moorestown, New Jersey, was proposed 

 as a contributor and elected. 



Orthoptera. Mr. Rehn made a few remarks on the species of 

 the Acridid genus Chhcaltis, showing, with the aid of a sketch map, 

 the distribution of the three species, one of which is now being de- 

 scribed by Mr. Hebard and himself. An interesting feature of the 

 geographic size variation found in the genus was also discussed. 



Lepidoptera. Mr. Laurent exhibited a series of nine males of 

 Eurymns (Colias) philodice Gdt. collected at Mt. Airy, Philadelphia, 

 in which the specimens show considerable variation in the number and 

 size of the spots in the submarginal space of the under side of the 

 wings. No. i has seven large markings on each of the fore wings 

 and six on each hind wing, while No. 9 is without markings on the 

 fore wings and only three faint marks on each of the hind ones.
