V. I. p. -51) gives a note on the cocoon, and 

 adds Syn'iigii to the tbod-plants. Miiiot 

 (Can. entom., May 1S70, v. 2, p. 100) com- 

 piles a list of the food-plants of the larva, 

 adding to those mentioned above, Beibeyis, 

 Bettila^ Acer, ^nerciis, sometimes Thuja, and 

 Piiiiis, Faffiis, apple, peach, plum, silvei"-bell 

 \_H(tle.sia~\. Riley (4th ann. rept. state entom. 

 Mo., 1S7J, p. 121-123) describes the egg, five 

 larval stages, and tlie cocoon, and figures 

 larva, cocoon, and male and female imagos; 

 he atlds [..iriodcndron to the tbod-plants. 

 Lintner (Entom. contrib., no. 3, 1S74, p. 126) 

 describes egg and young larva. W. H. Ed- 

 wards fPsyche, Jan. [27 June] iSSi, v. 3, p. 

 i6i, 171-174) discusses the variability in the 

 number of molts of A. prometliea, showing 

 that it molts, in West Virginia, only three 

 times, thus having four stages. Brodie (Pa- 

 piiio, May 18S2, v. 2, p. S3) gives a note on 

 time of emergence, copulation, and oviposi- 

 tion of this species. Saunders (Can. entom., 

 Dec. 1SS3, V. 15, p. 231-233) uses Riley's fig- 

 ures of larva, cocoon, and male and female 

 imagos, and adds Poptihis to the food-plants 

 of the larva. 



AiL:ctis polyfliemus Fabr. (Species in- 

 sector., 1781, V. 2, p. i58). Among the very 

 numerous articles which have been published 

 concerning this species the following are 

 worthy of citation. Harris (Rept. ins. injur, 

 veg., 1S41, p. 27S-279) describes larva, cocoon 

 and imago; later (Treatise on ins. injur, veg., 

 1862, p. 3S4-3S6) he adds a figure of the im- 

 ago, and (Entom. corresp., 1869. p. 294, pi. 

 4. fig. 17) a figure of the larva. Morris (Sv- 

 nop. lepid. N. A., 1862, p. 226-227) describes 

 larva and imago, and [op. cii., p. 209) de- 

 scribes the egg, which he mistook for that of 

 Smerifit/ms exciircntiis. Tixjin-elot (.Vmer. 

 nat.. 1867, V. I, p. 30-38, S5-94, 145-149, pi. 

 5-6) gives an extended account of this species 

 which he tiled to rear, on a considerable 

 scale, for its silk ; he describes the egg, larva, 

 pupa, and cocoon, and figures the larva, pupa, 

 cocoon, and male and female imagos, as well 

 as Op/linn murritrinn . a parasite of the lar\'a; 



he says there are at least six varieties of the 

 imagos. Packard (Guide study ins., 1869, p. 

 297, pi. 6-7) repeats Trouvelot's figures. Ri- 

 ley [.-"J (Amer. entom., March 1S69, v. i, p. 

 121-122) figures the imago and describes the 

 larva and imago. Riley (4th ann. rept. state 

 entom. Mo., 1872. p. 125-129) describes egg, 

 larva, cocoon, pupa, and imago, and figures 

 larva, pupa, cocoon, and male and female 

 imagos: contrary to Trouvelot. who stated 

 that there are six larval stages, Riley gives 

 the niunber of molts as four, making five 

 larval stages. Lintner (Entom. contrib. 

 [no. i], 1S72, p. 6) gives a note on the color- 

 ation of the eggs, and {op. ci/., no. 3, 1S74, 

 p. 152) describes the egg. Gentry (Can. en- 

 tom.. May 1874, V. 6, p. S6) describes the 

 normal form and a variety of the larva. Grote 

 (Can. entom., Sept. 1S78, v. 10, p. 176) states 

 that this species is double-brooded in the 

 south; Trouvelot (/. c.) was unable to raise 

 two broods to maturity in Massachusetts, and 

 Brodie (Papilio, April 18S2, v. 2, p. 60) writes 

 that, "in long and warm seasons about 50 

 per cent, are double brooded, but this is 

 against the increase of the species, as cold 

 weather usually sets in before the larvae are 

 fully matured." Packard (Bull. 7, U. S. en- 

 tom. comm., iSSi, p. 48) figures the larva. 

 Saunders (Can. entom., March 1882. v. 14, 

 p. 41-45) figures and describes the larva, 

 pupa, cocoon, and nuile and female imagos; 

 he further figures Of'hion mcnriiiuiii. a para- 

 site of the larva. Brodie (Papilio. May 1S82, 

 V. 2, p. 83) states that normally this insect 

 comes from its cocoon at about 11 a.m. 

 Wailly (Bull. Soc. acclim. France. May 18S2, 

 s. 3, V. 9, p. 265) gives some notes upon the 

 larva and imago. A compilation of the food- 

 plants r'esults as follows : .^iiercits, U/inus, 

 Tilia [Harris, (841 and 1S62] ; Tilia amcii- 

 cainj and Rosa [Mai'ris, 1S69] ; Acer, Salix. 

 Popiilns, Coryliif, Betiila, Va c c i iii 11 m [Tr^ou- 

 velot] ; Carya, yitg/aus nigra. J. chierea, 

 Crataegus. (Amer. entonr., 1S69, v. i, p. I2X) ; 

 ^uercus viretis, [Chambers (Amer. entom., 

 March rS70. v. 2, p. 156)] ; apple, quince.
