110 PROCEEDINGS ENTOMOLOGICAL SOCIETY 



Mr. Rohwer replied to a question by Dr. Howard, saying 

 that the species had been found in Washington, D. C.; Falls 

 Church, Virginia; Riley County, Kansas; and Texas, a fe- 

 male being in the Belfrage collection. 



Mr. Marlatt thought the species as widely distributed as 

 the host plant. 



Mr. Rohwer said that most of the species of Blennocampinae 

 defoliated deciduous trees. That the species seemed to pre- 

 fer the new young growth. That many of our native species 

 defoliate various species of oaks, Dr. Dyar having bred many 

 new species of Periclista and Isodyctium from larvae on oaks. 



In reply to a question by Mr. Webster about breeding saw- 

 flies, Dr. Dyar said that the only way was just to keep after 

 them. 



Mr. Cushman stated that during the course of some obser- 

 vations on a sawfly of the genus Caliroa which he conducted 

 at Tallulah, Louisiana, during the past summer (1910), he had 

 great difficulty in carrying the immature stages through to 

 maturity. He therefore devised a combination feeding and 

 pupating cage as follows: An ordinary tumbler was filled with 

 earth, into which, at the center, was thrust a small phial, and 

 at the side a glass tube open at both ends. The phial was 

 for the reception of a peach twig and was filled with water to 

 keep the food-supply fresh. The tube was for moistening the 

 earth from the bottom instead of puddling the surface. An 

 ordinary lantern globe, the top of which just fitted inside the 

 tumbler, was inverted over the tumbler, and closed above with 

 a square of cheesecloth. With this cage a large proportion of 

 the larvae confined were carried at least to the time of en- 

 trance into the ground and many matured under conditions as 

 nearly natural as is possible to obtain in a breeding cage. It 

 would probably be a successful cage for almost any ground- 

 pupating insect.
