THE CANADIAN ENTOMOLOGIST. 109 



seemed to be much less sprightly. Finally his song, instead of filling the 

 room, was but a faint sound, and I was obliged to place my ear close to 

 the tin can. This was nearing the end, which came either on the tenth or 

 eleventh of September, I cannot say which, for the bowery was not dis- 

 turbed until its occupant had been missing from the upper leaves for 

 several days. 



Once or twice during his captivity he took unnecessary alarm at my 

 well-meant efforts to "fix" the bowery, and whacked his head most 

 insanely against the tin can, being propelled thereto by his muscular hind 

 legs. However, no harm seemed to result from these little fits of nervous- 

 ness, and he evidently died quietly enough in the end. 



I have observed in other kinds of grasshoppers the subsidence in the 

 volume of song as they grew older, which evidently makes it unsafe to 

 take the efforts of a single individual as the standard of the species, 

 especially if the time is late in the fall. 



NOTES ON LEUCANIA PSEUDARGYRIA, GUEN. 



BY REV. THOMAS W. FVLES, F. L. S., SOUTH QUEBEC. 



Full-grown larva. — Length, two inches. Colour greenish-brown 

 above, greenish-grey beneath. Pale dorsal and side lines. Spiracles 

 black. Head and scale on second segment light reddish- brown ; jaws 

 darker brown. This description agrees with that given by Mr. Caulfield 

 in Vol. XIII. of the Canadian Entomologist, page 132. 



The larvae, like those of Arzama obliquata, feed in the stems of Typha 

 latifolia. The two species may sometimes be found in the same plant. 

 They are plentiful in the swampy ground at the foot of Mount Royal, 

 Montreal. Both sometimes become the prey of the maggots of Chcetopsis 

 cenea, Wied. 



Pupa. — Length, one inch and a-quarter. Colour light brick-red. 

 Forepart rounded abruptly and terminating in a beak-like projection, 

 resembles the head of a bird. Thoracic portion of case curves backward 

 on either side to a point. Wing cases large. 



My specimens underwent the pupal change amongst the accumulated 

 frass in their tunnels ; but doubtless the larvse sometimes leave the food- 

 plant and seek hibernacula elsewhere, as do those of Arzama obliquata. 

 '(See Mr. Caulfield's notes referred to above.)
