to cease near the borders of the transition. Mr. Schwarz stated 

 that many similar instances might be mentioned, and in the fact 

 of our greater summer heat in this country, as compared to 

 Europe, we have one of the reasons for the greater damage ac 

 complished by introduced insects, since here they have more 

 generations annually. Scolytus rugulosus, for example, is 

 double-brooded in Europe, while here it may have six generations 

 annually. Dr. Gill, referring specifically to Mr. Marlatt's paper, 

 asked whether it did not indicate that early apple culture should 

 be abandoned in the transition zone. Mr. Marlatt stated that 

 it indicated, rather, a necessity for spraying summer apples 

 only. Mr. Howard spoke of the possible spread of the gypsy- 

 moth, and Mr. Schwarz called attention to the fact that insects 

 introduced in the vicinity of Boston rarely spread. 

 Mr. Ashmead read the following paper : 



ON THE GENUS PELECINELLA WESTWOOD, AND ITS POSI 

 TION AMONG THE CHALCIDID^E. 



By WILLIAM H. ASHMEAD. 



Nearly twenty-seven years ago the genus Pelecinella was 

 erected by the late Prof. John O. Westwood for the reception of 

 a peculiar Chalcidid collected by Bates along the banks of the 

 Amazon in Brazil, the description being published in the Pro 

 ceedings of the Entomological Society of London for the year 

 1868. 



In his classical work " Thesaurus entomologicus oxoniensis," 

 published in 1874, Westwood redescribes the genus, and on plate 

 xxvi, fig. 8, gives an admirable illustration of the type Peleci 

 nella phantasma. 



Up to the present time this single species is the only one known 

 and it is probably extremely rare, as, during this long interval of 

 twenty-seven years, no other authority, that I am aware of, makes 

 mention of its capture. The types in the Hope Museum at Cam 

 bridge must therefore be the only ones in existence. 



It affords me, therefore, the greatest pleasure to exhibit to you 

 tonight two new species belonging to this rare genus, discovered 

 in the Herbert Smith collection now in my hands for naming, 

 and to dedicate one of these to the grand old English entomolo 

 gist, John O. Westwood, the other to our fellow-member, Mr. 

 L. O. Howard.
