figure of the larva and imago, and (Entom. Corresp., 1869, p. 287,288) he descrihes 

 the larva and pupa. Morris (Synop. Lepid. N. A., 1862, p. 342, 343) describes larva 

 and imago. Riley (Amer. Entom., Jnly-Aug., 1870, v. 2, p. 272, 273 and 3rd Ann. Rept. 

 State Entom. Mo'., 1871, p. 68, 69) describes and figures the larva, pupa, and imago, 

 adding to the above-mentioned food-plants, Juglans cinerea, Syringa, Convolvulus, 

 Gossypium, Helianthus, Polygonum, Verhena, and Geranium; he also states that the 

 larva has been known "to subsist entirely, from the time it cast its last skin till it 

 spun up, on dead bodies of the camel cricket {Mantis Carolina) "; later (oj). eit , Oct., 

 1870, V. 2, p. 336) he adds Petunia and Salix to the food-plants. Lintner (Entom. 

 Contrib., No. 3, 1874, p. 143) describes two varieties of the larva. Bates (Can. Entom., 

 Jan., 1880, v. 12, p. 20) adds fRumex to the food-plants. Saunders {op. cit., March, 

 1880, V. 12, p. 56, 57) reprints Riley's figures of the larva, pupa, and imago, and de- 

 scribes them. Packard (Bull. 7, U. S. Entom. Comm., 1881, p. 88-89) describes larva 

 and imago (reprinting Riley's figures of these and the pupa) and adds Bhainnus and 

 Pin «8 to the food-plants. The larva also eats Ampelopsis quinquefoUa, Ulmus ameri- 

 cana, Betula alba, Fuchsia fulgens, Tropceolum, Prunus serotina, Syringa vulgaris, Vitis 

 labrusca, Ipomoea purpurea, Pelargonium, Martynia proboscidea, Acer saccharinum, 

 Eicinus communis, Lappa officinalis, and Nicotiana tobacum, but specimens fed on Datura 

 meteloides died soon after. (Anna K. Dimmock, Psyche, iv, p. 281.) 



16. Phobetron pitbecium Abbot and Smith. 



As will be seen by the following statement by Mrs. Dimmock this 

 singular caterpillar is sometimes found on the birch as well as the oak 

 (seep. 143): 



Phobetron pithecium Abb. and Smith (Nat. Hist. Lepid. Ins. Ga., 1797, v. 2, p. 147, pi. 

 74). Harris (Rept. Ins. Injur. Veg., 1841, p. 304,305) describes the larva and imago 

 of this species, stating that the larva feeds on oak, and, according to Melsheimer, on 

 wild cherry; later (Treatise on Ins. Injur. Veg., 1862, p. 421,422) he adds to this de- 

 scription a poor figure of the larva and of the cocoon ; he gives a brief note (Entpm. 

 Correep., 1869, p. 244-245) on the larva. Riley (Amer. Entom. v. 2 ; September, Oc- 

 tober, 1869, p. 25 ; October, 1870, p. 340) gives a good figure of the larva, which he 

 states to feed on apple and Siberian crab-apple ; he later (5th Ann. Rept. State Entom. 

 Mo., 1873, p. 126) gives this sj^ecies in a list of larvaj which have urticating power. 

 Lintner (Eutom. Contrib., No. 3, 1874, p. 149) describes the cocoon, and adds plum, 

 pear, and Corylus americana to the food-plants. This larva is rarely found in eastern 

 Massachusetts but is. a little more abundant in the western part of the State; a 

 favorite food-plant is Betula alba. (Anna K. Dimmock, Psyche, iv, p. 208.) 



17. Limacodes scapha Harris. 



The following notes are copied from Mrs. Dimmock's paper : 



Limacodes scapha Harr. (Rept. Ins. Injur. Veg., 1841, p. 303). Harris {I. c. and 

 Treatise ou Ins. Injur. Veg., 1862, p. 420) describes the species as larva, which he 



(Can. Entom., July, 1873, p. 137) adds a few notes on the larva. Siewers (Can. 

 Entom., July, 1877, v. 9, p. 127, 128) notes a few habits of the larva. Mann (Psyche, 

 Sept.-Dec, 1879 [9 Apr., 1880], v. 2, p. 270) gives some notes on the larva. Riley 

 (Amer. Entom., June, 1880, v. 3, p. 133, 134) reprints his figures of larva, pupa, and 

 imago, and adds some notes on the larva and its jiarasites. Coleman (Papilio, Jan., 

 1882, v. 2, p. 18) gives some notes on the variations of color of the larva. Experi- 

 ments show that the larva feeds readily on leaves of the following plants : Ricinus 

 communis, Acer saccharinum. Viburnum dentatum. Lappa officinalis. Polygonum persicaria, 

 Tropa'olum majus, Vitis labrusca, Syringa vulgaris, S. jyersica, Ampelopsis quinquefoUa, 

 Prunus serotina, Ulmus americana, Clethra alnifolia, Martynia proboscidea, Helianthua 

 annuus, Plantago major, Spirwa sorbifoUa, Ribes aureum, and Betula alba; the larva 

 refused Solanum nigrtini and Apios tuherosa. (Anna K. Dimmock, Psyche, iv, p. 281.)
