LEPIDOPTERA. 309 



wards. This Notodonta is a neat and trim looking moth, and is 

 hence called concinna by Sir J. E. Smith. It is of a light brown 

 color ; the fore-wings are dark brown along the inner margin, and 

 more or less tinged with gray before ; there is a dark brown dot 

 near the middle, a spot of the same color near each angle, a very 

 small triangular whitish spot near the shoulders, and several dark 

 brown longitudinal streaks on the outer hind margin ; the hind- 

 wings of the male are brownish or dirty white, with a brown spot 

 on the inner hind angle ; those of the other sex are dusky brown;' 

 the body is light brown, with the thorax rather darker. The 

 wings expand from one inch to one inch and three eighths. 



There are ten or more kinds of Notodonta in Massachusetts, 

 all of them differing from the preceding, and more or less from 

 each other ; the caterpillars of the last of them are cylindrical, 

 with only a slight elevation or wart-like prominence on the top of 

 the eleventh ring ; but' as these insects, however interesting as 

 objects of natural history, are not particularly worthy of notice 

 on any other account, they must be passed by here, without further 

 remarks. 



Every person who has paid any attention to the cultivation of 

 the grape-vine in this country must have observed upon it, be- 

 sides the large sphinx caterpillars that devour its leaves, a small 

 blue caterpillar 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 forepart of the body hunched up when the crea- 

 ture is at rest. These caterpillars begin to appear about the mid- 

 dle 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, bury-
