Description of and Notes upon various larvsB. 

 By Albert Koebele. 



Daremma catalpae, Bois. 



Mature larva: length about 3 inches, head orbicular, of medium size, 

 jet black, with some yellow on the mouth pieces, and slightly retractile 

 under the first segment of the body. Body cylindrical, first segment a 

 little larger than the head, and from this the body regularly and gradually 

 becomes larger to the last segment. There is a broad jet black dorsal 

 band running from the head the whole length of the body past and in- 

 closing the caudal horn and embracing the upper anal covering. This 

 band extends on either side of the dorsal line about halfway to the stig- 

 mata. It is edged on each side with a yellow line, and this by a black 

 line. Below this there is a stigmatal yellow band partially crossed with 

 black dashes more pronounced at the center of each segment. Below this 

 at the summit of the legs is an uninterrupted black band extending the 

 whole length of the body. Beneath the body is clear yellow. The stig- 

 mata are yellow with a black dot above and below. The caudal horn is 

 jet black, long, linear, straight and pointed. The prolegs are black, the ab- 

 dominal legs yellow. The larva feeds on Catalpa bignonioides. Walt. 



There is a variety of the larva much more rare in which the black is 

 much lessened; where in the place of the broad black band above there 

 is an interrupted dorsal and two sub-dorsal black lines. The face and 

 mouth parts in this are yellow. 



The egg is light green. It hatches in 6 days. The growth of the 

 larva occupies about 3 weeks. It pupates in the ground and is in the 

 pupal state 16 or more days. There are consequently several broods each 

 vear. The larva after the first moult has a large dorsal and a small sub- 

 dorsal black spot on each segment. These after the third moult become 

 the continuous black band. 



The eggs are laid in clusters, on the undersides of the leaves. 



Sphinx Coniferarum, Ab. & Sm, 



Mature larva; the larva of this insect was originally figured by Ab- 

 bott & Smith and is by them represented as being checkered with light and 

 dark gray squares. This form was found by me at Tallahassee, on Pinus 

 palustris, but infested by parasites and another in the jaws of Pasimachus 

 subsulcatus; but as feeding indiscriminately on all kinds of pine, the 

 much more common form is light yellowish green in color with three white 

 lines on each side/— one just below the dorsal line — a second stigmatal —
