Sci. vol. xxxvi). According to Mr. Walker, neither of tliem 

 is in the collection of the British Museum. Dead fish appear to 

 be very attractive bait for Sphinges as well as other Lepidoptera, 

 one of the species above mentioned having been taken whilst 

 hovering over a dead carp lying by the water side, and many others 

 were seen under similar circumstances. On the 11th August, 

 when camped on a low flat at the base of Silver Mountain on 

 the Rouge, I obtained a Sphinx larva, which from my notes, ap- 

 pears to have resembled that of S. Kalonice, as described by Harris 

 (vide Amer. Journ, Sci. vol. xxxvi, p. 295). It was light green, 

 with seven obHque yellow stripes edged above with dark purple, 

 on each side ; head yellow, with a vertical band of dark brown on 

 either side ; caudal horn, blue, covered with small black tubercles, 

 and tipped with black. It appeared to have been washed by 

 the heavy rain which had just fallen during a violent thunder 

 storm, from the soft maples [Acer ruhrimi), which almost exclu- 

 sively surrounded the tents, and on one of which it was crawling. 

 Another splendid larva was found on the 19th September, feeding 

 on a bush of Myrica gale, growing on the shores of Green 

 Lake, adjoining the Lake of Three Mountains, in the county of 

 Ottawa, about five miles from Hamilton's Farm. The following 

 is the description of it which I made at the time : '' Deep olive- 

 green, covered with minute spots of white, edged with black ; 

 seven oblique pink stripes, edged above with black and below with 

 pale yellow, on either side ; caudal horn, black ; spiracles, orange ; 

 pro-legs, yellow ; a stripe of light green on each side of the head." 

 The minute white spots surrounded by black, thickly covering the 

 whole upper surface, gave it a striking and most interesting re- 

 semblance to the scurfy resinous dotted leaves of its food-plant, 

 the Bog Myrtle or Sweet Gale. This beautiful larva changed to 

 a pupa which unfortunately perished during the following winter. 



Smerinthus. I obtained two larvae, belonging to this genus, 

 under elm trees at Hamilton's Farm, on the 3rd and 4th Septem- 

 ber, of which the following are descriptions: No. 1, pale green, 

 whitish on the back, with oblique stripes of white and dark green 

 on the sides. No. 2, green, with oblique tuberculated stripes on 

 the sides, and two tubercles on each of the second and third seg- 

 ments, 



Trochilium. On the 25th June, at Sugar-bush Lake, I cap- 

 tured a beautiful and apparently undescribed species of Trochi- 

 lium, sitting on the blossoms of Viburnum ojmlus which were
