360 THE CANADIAN ENTOMOLOGIST. 



Dr. J. B. Smith read a paper entitled "Some Unrecognized Sexual 

 Characters of Noctuidse." The males of many Noctuids have character- 

 istic hair-tufts and hair pencils on the legs, and these reach their extreme 

 development in the Deltoid series. Many other Noctuids have pencils, 

 brushes and scale-tufts concealed in abdominal cavities, and of these 

 little or nothing has heretofore been known. A few of the principal forms 

 were shown on slides. 



Mr. J. Chester Bradley read "A case of gregarious sleeping habits 

 among Aculeate Hymenoptera." In the San Joaquin Valley in California 

 a large number of sleeping Hymenoptera were observed gathered inta 

 clusters. But each cluster contained only a single species, and there 

 were nine species represented in all. 



Prof. F. M. Webster spoke on "Parasitism of Toxoptera." Draw- 

 ings were exhibited, showing the movements of the larva when 

 parasitizing, which caused the body of the host to assume a characteristic 

 globose shape. 



Mr. Bradley read "The Evolution of the Wings of Evaniidcne." 

 The wings of this family portray in a remarkable manner the progress 

 of evolution. From a relatively complex venation we find gradual 

 steps through various degrees of atrophy, resulting in the almost com- 

 plete loss of venation. The paper was discussed by Dr. Holland and 

 Prof. Kellogg. 



The meeting then adjourned to a very enjoyable smoker in the. 

 Grundman Studios, at which the Society and its visitors were the guests 

 of the Cambridge Entomological Club. — J. Chester Bradley, Secretary- 

 Treasurer. 



Jamaican Hemiptera. — In the Bulletin of the Buffalo Society of 

 Natural Sciences (Vol. viii, No. 5, 1907, pp. 1-77), Mr. E. P. Van Duzee 

 gives a report on a collection of Hemiptera that he made in Jamaica 

 during a short visit in March and April, 1906. Though climatic and other 

 difficulties were great, heavy rains and tropical heat alternating in 

 rendering out-door work at times impossible, he was able to procure speci- 

 mens of 236 species, of which 85 are new to science, and among them are 

 representatives of no less than ten new genera; a large proportion of these 

 forms are described in this paper. The Capsidse collected were submitted 

 to Dr. O. M. Renter, of Helsingfors, who has described as new seven 

 genera, 29 species and two varieties from the material submitted to him. 

 Students of the order will welcome this valuable contribution to its 

 literature, in which are to be found many critical notes on species already 

 known, as well as the descriptions of new forms. The paper is rendered 

 all the more interesting and acceptable by the excellent portrait of the 

 author which forms its frontispiece. 



Mailed October 5th, 1907.
