SILK-PRODUCING LEPIDOPTERA. 43 



similar to P. gloveri, is found in various states and parts of 

 Canada. 



Callosamia promethea (Attacus promethea, Drury). Callo- 

 samia is the generic name given by Packard. The cocoon of this 

 species somewhat resembles that of Attacus cynthia, but is smaller 

 and more elongated ; the species altogether is smaller. The larva 

 can easily be bred in the open air on lilac or cherry, if the larvse 

 do not hatch too late in the summer. In America the larva feeds 

 on the Sassafras (wild cherry), Cephalanthus, Lauras, Benzoin, 

 Syringa, Berheris, Betula, Acer, Quercus, Pinus, Fagus, Lirio- 

 dendron, Populus, apple, pear, peach, &c. According to W. H. 

 Edwards, the larva of C. proiuethea has but three moults or four 

 stages in Western Virginia. 



Callosamia angulifera, Walker. A species which is said to 

 feed on the tulip tree ; is very similar to C. prometliea, but the 

 colours on the wings are the same in both sexes, whilst in 

 proiuethea they are very dissimilar. 



Philosamia CYNTHIA, Grote (Attacus cynthia, Drury). This is 

 the Attacus cynthia mentioned before, a native of China, and now 

 naturalised in the United States. 



Attacus splendidus, B. {Saturnia galhina ; Satarnia, Krank ; 

 galbina, Clem. ; Saturnia mendocino, Behrens). 



AcTiAS LUNA [Attacus luna, Linn.). Actias, generic name, 

 given by Leach. A species smaller, but resembling the A. selene 

 of India. The cocoon, closed like those of the same genus, is 

 irregular, and has but little silk. In the United States the 

 species is double- brooded. The larva, which is green, with red 

 tubercles, has often been reared in Europe, where it seems to 

 prefer walnut; it is, however, very polyphagous. The food- 

 plants mentioned by American entomologists on which the 

 larvae are said to be found are the following : — Juglans cinerea, 

 Carya porcina, Quercus, Plantanus, Liquidamhar, Fagus, Betula, 

 Salix, Ostrya virginica, Castanea, and plum. 



Hyperchiria 10, Fabricius. The larva of this species forms 

 its pupa in a light cocoon or shell on the surface of the ground ; 

 it is covered with tufts of stiff hairs, which sting like nettles. It 

 is easy to rear in captivity. The moths, which are very hand- 

 some and differ in the sexes, pair easily. The larva, which has 

 six stages, has been reared in Europe on oak, willow, plum, 

 apple, &c. In America it is found on Populus halsamifera, 

 Uimus, Zea mays, Cornus, Sassafras, Quercus, Eobinia viscosa, 

 Cornus florida, Liriodendron, Humulus, Gossypium, Acer, Salix, 

 Populus tremuloides, Eobinia pseudo-acacia, Cerasus virginiana, 

 Betula, Fraxinus, Rabus villosus, Trifolimn pratense, &c. 



Attacus aurota, Cramer. Large and fine species, somewhat 

 resembling Attacus atlas, being sometimes called the South 

 American atlas. It is found in the Guianas, other parts of 

 Central America, and Brazil, where there is a variety bearing
