MEETING OF THE ENTOMOLOGICAL CLUB OF THE AMERICAN 

 ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE. 



Pursuant to notice, the members of the Entomological Club of the A. A. A. S. met 

 at 2.30 p.m., September 3, 1884, at the Hotel Lafayette, in Philadelphia. Present : 

 Herbert Osborn, Ames, Iowa ; Dr. John G. Morris, Baltimore ; Dr. G. H. B orn, Dr. 

 Henry McCook, Eugene M. Aaron, E. T. Cresson, Philadelphia, Pa. ; C. H. Female! , 

 Orono, Maine ; Rev. G. D. Hulst, John B. Smith, E. L. Graef, Brooklyn, N. Y, ; C. Y. 

 Riley, B. P. Mann, Washington ; J. H. Emerton, G. Dim mock, Cambridge, Mass. ; L. M. 

 Underwood, Mr. Larkin, Syracuse, N. Y. ; Dr. P. R. Hoy, Racine, Wis. ; Wm. Saunders, 

 Lonelon, Ontario ; J. A. Lintner, Albany, N. Y. ; Dr. Maclosky, Princeton ; Dr. Hart* 

 Merriam, Locust Grove, N. Y. ; H. H. Lyman, G. J. Bowles, Montreal ; Prof. Martin, 

 Messrs. Moore, Hunt, Casey, Wenzell, and others. 



In the absence of the President, D. S. Kellicott, of Buffalo, N. Y., the Vice-Presi- 

 dent, Hei'bert Osborn, was called to the chair. A letter was read from Mr. Kellicott, 

 regretting his inability to attend. 



The election of officers was then proceeded with, and resulted as follows : — 



President Dr. John G. Morris. 



Vice-President Herbert Osborn. 



Secretary John B. Smith. 



Dr. G. H. Horn made some remarks on the historic associations connected with the 

 spot where the present meeting was held. Many years ago when this site was far out of 

 the City of Philadelphia, the Museum of Natural History was there erected, and in the 

 corner occupied by Parlor C of the hotel, stood the skeletons of a horse, ox or other large 

 mammal. Here Thomas Say, poor in pocket, though rich in brain, having no other place 

 to go, put up his beel under these skeletons, and that for many months was his only home ; 

 there also he contracted the illness which eventually caused his eleath. 



The Secretary then read a short paper by D. S. Kellicott, as follows : 



A XOTE : OVIPOSITIXG APPARATUS OF NONAGRIA SUBCARNEA. 



At the Minneapolis meeting of this Club, I reael a note on the life history of this 

 species, the substance of which, together with a brief description of the moth, has since 

 appeared in the American Naturalist. Since then I have ascertaineel how the eggs are 

 placed and protected through the winter, anel have examined somewhat the structure of 

 the egg-placing apparatus. I have submitted an account of this moth to the Publication 

 Committee of the Buffalo Society of Natural Sciences, from which I am permitted to 

 extract the following remarks. I enclose also a tin-type of the elrawings accompanying 

 the paper mentioneel, together with a fragment of a Typha leaf with the edges rolled over 

 rows of eggs. 



Figure 2 represents the ovipositing apparatus as seen from one siele and below. 

 Explanation is scarcely necessary. The last two abdominal joints are strangely modified, 

 constituting a complex apparatus. The last joint is laterally broad, chitinous, except at 

 base, terminating in two finger-like processes (c) ; these are rounded at the apices and 

 curveel downwards as represented in the drawing ; at b are two concave discs with a deep 

 groove (g) leading up to the anal orifice ; it is evidently along this channel that the eggs are 

 passed by the ovipositor ; on either siele and below the groove there is a strong chitinous 

 ridge with saw-like teeth pointed backward (e). The other modified ring consists of a 

 heavy harel band (a) with stout posterior processes for muscular attachment ; below are 

 two stout chisels (d) pointing backward and overlapping the first basal teeth of the 

 " saws " of the last ring. 



I have not succeeded in witnessing the act of oviposition. Numerous females were 

 kept in an abandoneel aquarium with Typha leaves, and the same watched faithfully ; it 

 was approached by day and by night, but all were concealed and cjuiet whenever observed. 

 Day by day I coiild finel additions to the stock of eggs, but the manner of performing the
