170 THE CANADIAN ENTOMOLOGIST. 



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 bed under these skeletons, and that for many 

 months was his only home ; there also he contracted the illness which 

 eventually caused his death. 



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



A NOTE : OVIPOSITING APPARATUS OF NONAGRIA SUBCARNEA. 



At the Minneapolis meeting of this Club, I read 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 ascertained how the eggs are placed and protected 

 through the winter, and 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 drawings accompanying the paper mentioned, 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 side 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 curved down- 

 wards as represented in the drawing 3 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 side and 

 below the groove there is a strong chitinous ridge with saw-hke teeth 

 pointed backward (e). The other modified ring consists of a heavy hard 

 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 abandoned aquarium with Typha leaves, and the 

 same watched faithfully ; it was approached by day and by night, but all 

 were concealed and quiet whenever observed. Day by day I could find 

 additions to the stock of eggs, but the manner of performing the delicate 

 operation of folding over and cementing down the leaf edge, forming a
