NOTES ON LARVA OF EUCHAETES EGLE, Clem. 



BY G. H. FRENCH, CARBONDALE, ILL. 



On July 5th, 1884, several larvcie of this species were handed me by a 

 neighbor, who had found them feeding on Asdepias quadrifolia growing 

 in the yard. They were just ready to pass the last moult, evidently leaving 

 the plant for the purpose of moulting; some of them being found on a fence 

 attracted the notice of the person finding them. As found ihey were .55 

 of an inch long ; body brownish black, each joint with eight tubercles 

 from which project tufts of hairs. Those from the four dorsal, on joints 

 2 and 3, are long and black, part of those on joint 4 are white ; the pos- 

 terior three joints also supporting long tufts. The dorsal tufts between 

 these are ochre colored, about a thi rd as long as the anterior or posterior, 

 and bend towards the centre from each side. The lower tufts on the 

 anterior part of the body are gray, the rest black. Head black. 



July 8, 9 and 10 quite a number more were found; both they, and those 

 in my breeding case, had moulted and returned to the food plant. They 

 must have gone quite a distance from the plant, as the fence and other 

 things for several feet around were carefully examined upon finding the 

 first, but only three or four were left feeding on the plants. 



At this time they were .80 of an inch long ; body velvety black, each 

 joint with ten tubercles, from each of which arises a spreading cluster of 

 hairs. Besides these, on the dorsal tubercles of joints 3 to 5 and 12 and 

 13, are pencils of finer hairs .25 of an inch long. All the hairs on joint 

 2 are white, short and point forward. In some specimens part of the 

 dorsal pencils on joints 3 and 5 are white ; also part of the hairs on joint 

 1 2 white, in others all are black. The dorsal pairs of tufts on joints 6 to 

 1 1 are turned towards each other so as to make a complete ridge, the 

 others on the sides point outward. The pencils on joints 6 to 1 1 are 

 about .15 of an inch long. Those on the back have the centre hairs ochre 

 with black underneath ; the laterals are black. Each one of the long hairs
