372 ENTOMOLOGICAL NEWS. [Oct., '07 



Dr. Bethune expressed the thanks of the Society to their 

 entertainers in Boston, and especially the Cambridge Entomolo- 

 gical Club. 



Dr. Smith offered a resolution, which was heartily con- 

 curred in, that the thanks of this Society be expressed to 

 Mr. Kirkland for the wonderful opportunity afforded them for 

 observing the experiments being carried on against the gypsy 

 and browntail moths, etc., at Saugus. 



There being no further business, the reading of papers was 

 entered upon. Papers were read as follows : 



Dr. J. B. Smith, "Some Unrecognized Sexual Characters 

 of Noctuidae," illustrated by lantern slides. The males of many 

 Noctuidae have characteristic tufts and hair pencils on the legs, 

 and these reach their extreme development in the Deltoid series. 

 Many other Noctuidae have hair pencils, brushes and scale- 

 tufts concealed on the abdomen, and of these little or nothing 

 has been known heretofore. A few of the principal forms 

 were shown on the slides. 



J. Chester Bradley, "A Case of Gregarious Sleeping Habits 

 Among Aculeate Hymenoptera." In the San Joaquin Valley, 

 this summer, wasps had been noticed sleeping in bunches. 

 Eight species were represented in considerable numbers, each 

 species always grouped separately. 



F. M. Webster, "Parasitism of Toxoptera." Illustrated by 

 drawings to show the various position assumed by the larva of 

 Lysiphlebus in parasitizing Toxoptera, and causing the latter 

 to assume characteristic rotund form of parasitized indivi- 

 duals. 



Discussion by Smith and Horvath. 



J. Chester Bradley, "The Evolution of the Wings of Evanii- 

 dae." Illustrated by charts. The wings of the Evaniidae por- 

 tray in a remarkable manner the progress of evolution. From 

 a relatively complex venation we find gradual steps thus var- 

 ious degrees of atrophy resulting finally in the almost com- 

 plete loss of venation. The group probably bi-phylletic. 



Discussion by Holland and Kellogg. 



W. L. Devereaux, "Slight Climate and Cicindela Faunal
