2. A. angelica Grote. Outer margin scalloped, especially in female ; thoracic 

 crest stronger, palpi longer; usually with two hyaline spots. Pale powdery gray; 

 ordinary lines reduced to blackish points on veins, the antemedial followed and 

 the postmedial preceded by shaded brown lines; transparent dots finely edged 

 with brown, with a vague brownish shade beyond them. No darker patch on inner 

 margin. Hind wing browner, the base luteous, with dark median and postmedial 

 shaded lines; outer margin brown. Under side pale, without dark shade in cell. 

 35 to nearly 50 mm. (H 40:21.) 



May to July. Rarer than A. torrefacta. Caterpillar strongly flattened, gray,

The Chinese silkworm belongs to the family Bombycidae (fig. 426, 430). 



Bombyx mori Linnaeus. 



Moth mostly white, with falcate wings; R,, R, and R 3 successively given off 

 from stalk of R, +5 ; M 2 nearly central in both wings; Sc and R somewhat 

 divergent, even from the base, but Rj placed well out and distinct; frenulum very 

 weak. The moths have fully-developed wings, but fly little or not at all. Cater- 

 pillars white, strongly humped on thorax, with a more or less distinct lateral 

 eyespot; with a strong caudal horn, and microscopic secondary hair. Cocoon 

 dense, normally of yellow silk. The silkworm is occasionally cultivated in our 

 territory, but is not known wild anywhere. Food black and white mulberry; 

 it will also eat Osage orange, and will also feed, especially when young, on 

 lettuce. (H p. 316 fl. 191-193.) 



Family 41. LASIOCAMPIDJE 



(Bombycidae, Lachneidae) 



Body and appearance about as in Apatelodes; normal. Spurs small. 

 Fore wing normally with all veins preserved, R, and R 3 long-stalked, 

 R 5 and M. l more shortly stalked from end of cell, R 4 often arising 

 out of the base of their stalk ; M 2 from Cu-stem, middle discocellular 

 vein long and angled. Cu., arising only one-quarter to one-third 

 way out on cell. Hind wing without any trace of frenulum, with 

 humeral angle broad and expanded, extending in front of fore wing 

 at rest and supported by one or more well-developed humeral veins; 

 Sc and R separate at base, then anastomosing or connected with R, 

 forming a cell of variable size ; M 2 arising from Cu-stem, Cu 2 attached 

 rather before middle of end of cell, not so near the base as in the 

 fore wing. 



Eggs, when laid singly, with micropyle on side, ovate; eggs of 

 Malacosoma clustered in a ring about a twig, such egg being laid on the 

 previous one so that the micropyle is at the exposed end; the whole
