zona, is particularly striking. Nearly the entire surface of the 

 beetle is covered with a heavy white coating and the integu- 

 ment is only visible at a few prominences which have evi- 

 dently been denuded. In the tribe Agrilini ornamentation of 

 an entirely different character is often present. This consists 

 of lines or patches of true scales, forming characteristic pat- 

 terns in different species. This may be noted in certain spe- 

 cies of Aorilii 5, Taplirocous., Hnichvs, and Pachyscelus. 



Mr. Jenue mentioned the rearing of a species of Cono- 

 trachelns (C. anaglyptirns) in Georgia. The eggs are laid in 

 the fuzz on the outside of peaches. The young larvae are un- 

 able to penetrate the skin, but when an artificial or accidental 

 puncture is made they develop successfully. The full-grown 

 larva, on emerging, is able to jump. 



Mr. Parks spoke of a leaf- mining fly (Agromyza sp.) in al- 

 falfa in southern Kansas, and of its parasites. 



The Secretary read a note by Mr. F. Alex. McDermott on 

 the predaceous habits of a pentatomid larva upon caterpillars. 

 The paper was discussed by Messrs. Webster and Heidemann.
