p. 77) briefly describes the larva, cocoon and 

 imago, figuring the last. A single larva of 

 this species, taken on Bciula alba at Bel- 

 mont, Mass, \z Aug. 1S82, pupated 17 Sept., 

 and emerged 1 July 1S83. The excrement 

 of the larva lias a peculiar form, being cup- 

 shaped, with a deep concavity, and coni- 

 parativelv thin walls which are somewhat 

 shrivelled about the margin in drying. The 

 larva, when disturbed, exhales an odor diffi- 

 cult to describe. A short time before pupa- 

 tion it turns whitish. 



Phobctron pitheciiim Abb. & Smith (Nat. 

 hist, lepid. ins. Ga., 1797, v. 2, p. 147, pi. 74). 

 Harris (Rept. ins. injur, veg., 1S41, p. 304- 

 305) describes the larva and imago of this 

 species, stating that the larva feeds on oak, 

 and, according to Melsheinier, on wild cher- 

 ry ; later (Treatise on ins. injur, veg., 1S62, 

 p. 421-422) he adds to this description a poor 

 figure of the larva and of the cocoon ; he 

 gives a brief note (Entom. corresp., iS6y, p. 

 244-245) on the larva. Riley (Amer. entom. 

 V. 2 : Sept.-Oct. 1S69, p. 25 ; Oct. 1S70, p. 340) 

 gives a good figure of the larva, which he 

 states to feed on apple and Siberian crab- 

 apple; he later (5tli ann. rept. state entom. 

 Mo., 1873, p. 126) gives this species in a list 

 of larvae which have urticating power. Lint- 

 ner (Entom. contrib., no. 3, 1S74, p. 149) 

 describes the cocoon, and adds plum, pear, 

 and Coiyliis americaiia to the food-plants. 

 This larva is rarely found in eastern Massa- 

 chusetts and a little more abundant fn the 

 western part of the state ; a favorite food- 

 plant is Betula alba. 



Orgyia leiicostigma Abb. & Smith (Nat. 

 hist, lepid. ins. Ga., 1797, v. 2, p. 157, pi. 79). 

 Harris (Rept. ins. injur, veg., 1841. p. 261- 

 263) describes th^ eggs, larva and imago of 

 this species; apple and Rosa are given as 

 food-plants. The same author (Treatise on 

 ins. injur, veg., 1S62, p. 366-368) figures and 

 describes the eggs, larva, cocoon, and male 

 and female imagos, and adds Ae$riilus liifpo- 

 castuHumto the food-plants; later (Entom. 

 corresp., 1S69, p. 291) he adds futher Salix, 



Ccl/is and Carya to the food-plants. Fitch 

 (ist and 2nd rept. ins. N. Y., 1S56, p. 202-220) 

 describes the diflferent stages of this species, 

 noting in addition to food-plants mentioned 

 above, Ulmiis, Acer, ^uerciis. and plum. 

 Riley (ist ann. rept. state entom. Mo., 1S69, 

 p. 144-147) figures and describes briefly the 

 eggs, larva, pupa, cocoon and male and fe- 

 male imagos; the figure of the larva is re- 

 peated in Amer. entom., Sept. 1870, v. 2, p. 

 306. Saunders (Can. entom., Apr. 1S71, v. 

 3, p. 14-15) repeats Riley's figure of the larva, 

 and describes the egg and egg-mass. Pack- 

 ard (Bull. 7, U. S. entom. comm., 1S81, p. 

 239) repeats Riley's figures of the different 

 stages of this species. Coleman (Papilio, 

 Nov. -Dec. 18S2, V. 2, p. 164-166) describes* 

 some variations in the coloration of the lar- 

 vae. Clarkson (Can. entom., Sept. 1SS3, v. 

 15. p. 16S) mentions that this larva particu^^ 

 larly attacks the silver-leaf Popiiliis, and 

 calls attention to the fact that ichneumons 

 oviposit in cocoons of this species. The 

 larva feeds upon Bclitla alba and B. leiita. 

 Hyfhanlria textor Harr. (N. E. farmer, 22 

 Aug. 1S28, V. 7, no. 5, p. 34). Harris, Rept. 

 ins. injur, veg., 1S41, p. 254-255) describes 

 the larva, cocoon and imago of this species. 

 giving apple and Ulmus as food plants of the 

 larva; later (Treatise on ins. injur, veg., 

 1S62, p. 357-358, pi. 7, fig. 10-12) he repeats 

 these descriptions and adds figures of larva, 

 cocoon, and pupa. Morris (Synop. lepid. 

 N. A., 1862, p. 344) gives a brief description 

 of larva and imago. Harris (Entom. corre*p., 

 1S69, p. 360) quotes the original descriptions 

 of larvaand imago Riley [.'] (Amer. entom., 

 Nov. 1869, v. 2, p. 39) givts as food-plants,
