as he had found a hundred or more of the chrysalids in the 

 bags formed by the caterpillars drawing together the leaves 

 of their food plant. 



Mr. G. M. Greene mentioned rinding three males and a num- 

 ber of females of Megarhyssa greenei Vier. on dead oak trees 

 at Overbrook Seminary, near Philadelphia. They varied 

 much in size. 



Dr. Skinner exhibited specimens of Oncideres putator and 

 said the species was probably rare in collections. If there is a 

 single brood, this might be accounted for by their late appear- 

 ance. The specimens were taken by Rehn and Hebard in Syca- 

 more Canon, Baboquivari Mountains, Pima Co., Arizona, Oc- 

 tober 6-9, 1910; Palo Alto Ranch, Altar Valley, Pima Co., 

 Arizona, October 6-10, 1910; Tucson, Arizona, October 3-4, 

 1910, and Snyder's Hill, Pima Co., Arizona, October n, 1910. 



Mr. C. J. Cole reported having seen Pelecinus polyturator in 

 considerable numbers at Chicago, Illinois. Mr. Greene said 

 they were often plentiful at Castle Rock, Pa. 



Dr. Calvert exhibited some Lampyrid larvae which were 

 given to him by one of the investigators of the photometric 

 laboratory of the United Gas Improvement Company, of 

 Philadelphia. He also exhibited a female Odonate, Libellula 

 exusta deplanata Rambur, collected by Mr. Philip Laurent 

 at Woodbury, New Jersey, May 14, 1912, apparently the first 

 record of this southern form in New Jersey. Also Enallagma 

 traiiatum, a female taken at Clementon, New Jersey, and E. 

 aspersum, a female from Mt. Airy, Philadelphia, both by Mr. 

 Laurent, both being rare in this part c 'r habitat. 



He also made an address on the Second Int> ational Ento- 

 mological Congress, held at Oxford, England, from August 

 5 to 10. The interest attached to the place, the old colleges, 

 the University Museum and the excursions were mentioned. 

 The changes in the entomological collection from the time of 

 Westwood to the present day were described. The special 

 character of the collections as illustrating mimicry, protective 

 resemblance, and food and habits of insects rather than sys- 

 tematics, was alluded to. HENRY SKINNER, Secretary.
