490 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
li^nr«* of the l;irv;i and Imago, and (Entom. Corresp., 18G9, p. 287, 288) he describes 
the larva and papa. Morris (Synop. Lepid. N. A., 186'2, p. 342, 343) describes larva 
and Imago. Riley ( Amcr. Entom., Jnly-Ang., 1870, v. 2, p. 272, 273 and 3rd Ann. Rept. 
stai«> Entom. M<>., 1871, p. 66, 89) deaeribei and fignree the larva, pupa, and imago, 
adding to the above-mentioned food-plants, Juglans cinerea, Syringa, Convolvulus, 
Cossi/jtiiun, Ihlianthus, Polygonum, Verbena, and (ieranium ; lie also states that the 
larva has been known "to subsist entirely, from the time it east its last skin till it 
spun op, on dead bodies of the camel cricket (Mantis Carolina)"', later (op. cit , Oct., 
1870, v. 2, p. 336) be adds Petunia and Salix to the food-plants. Lintner (Entom. 
('out rib., No. 3, 1874, p. 143) describes two varieties of the larva. Bates (Can. Entom., 
Jan., 1880, v. 12, p. 20) adds ? llumex to the food-plants. Saunders (op. cit., March, 
1880, v. 12, p. 56, 57) reprints Riley's figures of the larva, pupa, aud imago, and de- 
scribes them. Packard (Bull. 7, U. S. Entom. Cornm., 1881, p. 88-89) describes larva 
and imago (reprinting Riley's figures of these and the pupa) and adds Rhamnus and 
Pinits to the food-plants. The larva also eats Ampelopsis quinquefolia, Limits ameri- 
cana, Jietula alba, Fuchsia fulgens, Tropirolum, Primus serotina, Syringa vulgaris, Vitis 
labrusca, Ipomoea purpurea, Pelargonium, Martynia proboscidea, Acer sarcharinum, 
Ricinus communis, Lappa officinalis, and Nicotiana tobacum, but specimens fed on Datura 
meteloides died soon after. (Anna K. Dirumock, Psyche, iv, p. 281.) 
16. Phobetron pithecium Abbot and Smith. 
As will be seen by tbe following statement by Mrs. Dimmock this 
singular caterpillar is sometimes found on tbe birch as well as the oak 
(seep. 143): 
Phobetron pithecium Abb. aud 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 (Entom. 
Corresp., 1869, p. 244-245) on the larva. Riley (Amer. Entom. v. 2; September, Oc- 
tober, 18(39, 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 species in a list of larva) which have urticating power. 
Lintner (Entom. Coutrib., 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. Diinmock's paper: 
Limacodes scapha Harr. (Rept. Ins. Iujur. Veg., 1841, p. 303). Harris (I. c. and 
Treatise on Ins. Injur. Veg., 1862, p. 420) describes the species as larva, which he 
(Cau. 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 parasites. 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, 
Troptvolum majus, Vitis labrusca, Syringa vulgaris, S. persica, Ampelopsis quinquefolia, 
PruniiH serotina, Ulmus americana, Clethra alnifolia, Martynia proboscidea, JJelianthus 
animus, Plantago major, Spinva sorbi folia. Eibes aureum, and Betula alba; the larva 
refused Solatium nigrum and Apios tuherosa. (Anna K. Dimmock, Psyche, iv, p. 281.)
