upright in the sand. A few days later she was found dead, and 

 on close examination two or three very slight indications of 

 punctures were found in the smooth, hard bark. Many 

 clusters of eggs wen found by cutting into the bark, but in 

 very few cases could the puncture be detected before the eggs 

 were exposed. These punctures appear to have been closed 

 with a mucilaginous secretion which allows the disturbed and 

 broken fibers of the bark to swell back into their original 

 position before drying, when they are firmly cemented to- 

 gether. In some instances a thin membrane like dried 

 albumen covers the open spaces between the fibers. The 

 incision is a cylindrical cavity 8 mm. long and less than a 

 millimeter wide, paralh 1 to the surface and usually in the 

 inner bark, but often partly in the wood. One incision was 

 found in which the eggs were within the wood itself. The eggs 

 are laid alternately in a double row and usually number 12 

 or 13. The eggs measure 2.1 to 2.2 mm. in length by 0.35 

 mm. in width, are subcylindrical, slightly curved; one end 

 tapers more gradually and is nure evenly rounded, the other 

 is more bluntly conical. 



. The identity of the female is somewhat doubtful, but ap- 

 pears from comparison with specimens in the National Mu- 

 seum, and reference to Smith and Grossbeck's paper, to be 

 Cicada lyricen DeGeer. ' 



Dr. Hopkins thought these eggs w r ere truly those of the 

 cicada and complimented Mr. Barber on their discovery. 



Mr. Quaintance called attention to injury to walnut leaves 

 and shoots by the walnut curculio, Conotrachelus juglandis, 

 and exhibited photographs of the injury. Specimens of in- 

 jured leaves and shoots have been received the present season 

 from Titus ville, Pennsylvania, Upper Marlboro, Maryland, 

 and Stamford, Connecticut. Dr. R. T. Morris, writing of 

 the injury at Stamford, Connecticut, states: 



Ordinarly in the vicinity of my country place at Stamford, Conn., this 

 species has confined itself, so far as I know, to the involucre of J. cinerea; 

 at least I have never noticed it except there before. When I introduced 

 large numbers of exotic walnut trees this beetle changed its habits, finding 

 a suitable place for depositing its eggs in the rapidly growing herbaceous 

 shoots of the species of .Juglandarea 1 mentioned (Jnglans regia, J. 

 siboldii,}. cordifonnis,J. cinerea, and Hicoria minima). It has practi- 

 cally wiped out one orchard of/, regia for me and tlm-atms I he industry 



'This determination has very kindly been confirmed by Mr. W. T. Davis.
