ENTOMOLOGICAL NEWS. [Dec., '07 



At the meeting of the Feldman Collecting Social, held on 

 October i6th, at the residence of Mr. H. W. Wenzel, 1523 

 S. Thirteenth Street, Philadelphia, there were ten members 

 present, and Mr. Peters visitor. 



Dr. Skinner exhibited specimens of a local race of Cicin- 

 dcla Tiiltnrina from Fort Wingate, West New Mexico, which 

 are larger, more heavily marked and darker green than the 

 green variety of vulturina known as santaclarae. Black forms 

 were also received. 



Mr. Haimbach exhibited a few of the moths collected in the 

 past summer by Messrs. Kaeber and Wenzel, Jr., in Southern 

 Arizona, also a fine pair of Caripeta angustiorata Wlk., a rare 

 Geometricl, collected by Mr. Harbeck at Clementon, N. J., May 

 30, '07. 



Mr. Viereck said that out of about 250 specimens of Con- 

 necticut Braconidse (Hymenoptera), recently examined by 

 him, over fifty species proved to be new. Among the speci- 

 mens were some species of Lysiphlcbus, a genus that is para- 

 sitic on plant-lice, and that has been divided into species 

 groups by Dr. Ashmead, on the number of joints to the an- 

 tennae. Mr. Coquillett, in an article in Insect Life, disputes the 

 validity of some Ashmeadian species based on the above char- 

 acter, claiming that the number of joints to the antennae is 

 too variable to be of value, and gives, in support of his theory, 

 observations made upon Lysiphlebus species bred from col- 

 onies of Aphids, of which the specimens of each colony were 

 taken from the same bush. He examined over 100 specimens 

 of Dysiphlebus from two colonies, and of this number less 

 , than four per cent, showed more joints on one antenna than 

 ( >n the other, of the same species. Mr. Viereck remarked that, 

 in view of the fact that Mr. Coquillett's findings are not based 

 on generations from known parents, he is inclined to regard 

 Mr. Coquillett's view as a counter theory to that of Dr. Ash- 

 mead, and for the present prefers to stick to the latter. 



Mr. Daecke exhibited his collection of Trypetidae (Diptera), 

 and spoke on the gall-making of some of the trypetid species. 



FRANK HAIMBACH, Secretary.
