THE EUDRYAS GRATA. 427 



upon it, besides the large sphinx caterpillars that devour 

 its leaves, a small blue caterpillar F . 211 



(Fig. 211, and Plate VI. Fig. 7), 

 transversely banded with deep orange 

 across the middle of each ring, the 

 bands being dotted with black, with the head and feet also 

 orange, the top of the eleventh ring somewhat bulging, and 

 the fore part of the body hunched up when the creature is 

 at rest. These caterpillars begin to appear about the middle 

 of July, and others are hatched afterwards, as late, perhaps, 

 as the middle of August. When not eating, they generally 

 rest upon the under sides of the leaves, and, though many 

 may be found on one vine, they do not associate with each 

 other. They live on the common creeper, as well as on the 

 grape-vine. They eat all parts of the leaves, even to the 

 midrib and stalks. When fully grown, and at rest, they 

 measure an inch and a quarter, but stretch out, in creeping, 

 to the length of an inch and a half, or more. Towards the 

 end of August they begin to disappear, and no more will be 

 found on the vines after September. They creep down the 

 vines in the night, and go into the ground, burying them- 

 selves three or four inches deep, and turn to chrysalids with- 

 out making cocoons. The chrysalis is dark brown, and 

 rough with elevated points. The moths begin to come out 

 of the ground as soon as the 25th of June, and others con- 

 tinue to appear till the 20th of July. Though of small 

 size, they are very beautiful, and far surpass all others of 

 the family in delicacy of coloring and design. The name 

 of this moth is Eudryas grata * (Plate VI. Fig. 8), the first 

 word signifying beautiful wood-nymph, and the second agree- 

 able or pleasing. The antennae are rather long, almost 

 thread-like, tapering to the end, and not feathered in either 

 sex. The fore wings are pure white, with a broad stripe 

 along the front edge, extending from the shoulder a little 

 beyond the middle of the edge, and a broad band around the 



* This insect is the Bombyx grata of Fabricius.
