Meeting of January 17, 1917, at the home of H. W. Wenzel, 5614 

 Stewart Street, Philadelphia; nine members present. President H. A.

 corporated in the minutes. 



The following officers were re-elected to serve for 1917: President, 

 H. A. Wenzel; Vice President, Wm. S. Huntington ; Treasurer, H. W. 

 Wenzel; Secretary, Geo. M. Greene, and Assistant Secretary, J. W.

Lepidoptera. Mr. Haimbach exhibited a pair of a new form of 

 Automcris io Fabr., from Jemez Springs, New Mexico, June 21, 1916, 

 collected by Jno. Woodgate, which he will describe and name later. 

 Mr. Laurent stated that Saniia cccropia. Linn, was more plentiful in 

 Brooklyn, New York, than in Philadelphia, and that they have a dif- 

 ferent habit. Both this and last winter, while walking around the 

 Flatbush district of Brooklyn, he found that nearly every maple (?) 

 tree had from ten to thirty cocoons attached to the limbs. The strange 

 part was that there were as many cocoons on the branches of the up- 

 per half of the tree as on the lower half. Tn Philadelphia it is sel- 

 dom that more than three cocoons are found on a tree and these are 

 generally on the lower limbs. Mr. Daecke exhibited a specimen of 

 Scopelosoma moffatiana Grt., which he took on the wing, November 

 n, 1916, at Rockville, Pennsylvania. He said that this species most 

 likely hibernates in the adult state since there are also records of it 

 from very early spring. He also exhibited specimens of Scoliopteryx 

 libatri.r Linn, collected by Mr. Knull in a limestone cave near Hum- 

 melstown, Pennsylvania, January 7, 1917. This beautiful species, which 

 is closely allied to the one mentioned before, is known to hibernate 

 in the adult state. It is very common in Europe, where it is often 

 injurious to willow and poplar. 



General. Mr. Haimbach read his translation of a review by Prof. 

 Dr. Karl Eckstein (Eberswalde), in IHustrierte Zcitschrift filr Ento- 

 mologie, IV, p. 381, 1899, on the abnormal mating of insects by G. 

 Jakobson, Arbeiten der russischen Ent. Ges. (Laboratory work of the 

 Russian Entomological Society), Vol. 31, 1898 (Russian). 



In the above article Jakobson treats of three possibilities of ab- 

 normal mating: 



I. The mating between males and females of different genera and 

 even families: Buprestis x Elatcr; Elatcr x Telephorus; Tclcphorus
