brown in J, and are roseate and brown, the prolegs green, in G: the legs, 

 at tips, are rose-color, in E ; the length of R is 38 mm., that of G, 31-50 

 mm., and that of E, 63 mm., with a breadth of 10 mm. ; the mandibles of 

 R are black; the maxillas of E, within black; the labrum of E, rose-color. 



The food-plant of R (Fagus) is more closely related to those of .J (Os- 

 trya, Carya, Juglans) than to the food-plants of either E (Acer) or G 

 (? Prunus, ?Pyrus, Fraxinus, ? Ulmus, Salix). Harris, in Ent. Corr., 281, 

 mentions the squeaking habit of the larva of C. juglandis. 



Smerinthus modesUis. Very brief descr. of the larva in six 

 stages, by R. Bunker, in Can". Ent., ix (1877), 210-211. 



Length about 40 mm.^; stout. Color, after first moult [this seems to 

 correspond to the second moult, as described by Bunker], very dark green, 

 with yellowish granulations, which form, on third and fourth segments, a 

 sort of crest. A yellowish subdorsal line along each side of the dorsum. 

 The seven sloping side lines slightly yellow; the seventh or anal line, run- 

 ning from the fourth i)rok'g to the anal horn, thickly granulated. Anal 

 horn yellow. Feet yellow, tipped with pink. As the larva matures, all 

 the yellows become white, the body becomes pale green, and the anal horn 

 nearly disappears. Breathing holes edged with red. Head triangular, 

 with heavy granulations. Feeds on Poplar (Populus) in July and August.

 amyntor, by C. S. Minot, in Can. Ent., ii (1869), 28. Excel- 

 lent series of descriptions of the several stages, deserving, like 

 many of the subsequent descriptions of larvae by the same 

 author, to rank as a classic model, by Lintner, in Pr. E. S. Ph., 



^Mr. Andrews writes as follows, under date of Jan. 18.1878: "For myself I ear- 

 nestly protest against any metrical terms being used in any thing you may be pleased 

 to publish from my pen, and if you choose to use the jargon in my papers, I sliould 

 like you to note my protest."
