Dr. McCook continued with other instances. 



Mr. Smith also called attention to the stridulation in Crioceris 

 asparagi not as a new fact, as the same had been observed in Europe 

 whence the species has been introduced. 



Dr. Horn stated that stridulating Chrysomelidie are not numerous. 

 In reverting to the already published fact that Harpalus caliginosvs 

 stridulates quite loudly, he stated that H. pennsylvanicus, eompar and 

 their allies had similar powers as had been mentioned to him by 

 Dr. Hamilton. 



On motion of Mr. Aaron it was ordered that the committee ap- 

 pointed by the American Entomological Society to obtain a room in
