 of European coleoptera and colored drawings ot over 100 species 

 of Ottawa beetles. Mr. Gibson exhibited 13 species of moths 

 of which the larvae bore in the stems of plants, and also inflated 

 larvse of .several species. He explained that much work had been 

 done on these forms of late, especially by Mr. Bird, who had 

 reared many of the species. Mr. Lyman of Montreal, and others, 

 were also now studying them and developing their life histories. 

 Papaipema centssata, the larva of which was first discovered by 

 Mr. Lyman as a borer in ThalichiDn, was common at Meach Lake 

 in the common dock [Riimex occidejifalis), and P. cataphracta
