quite small. Skin densely and coarsely covered with subconic clear 

 granules, uniformly and without distinct depressed spaces, (i) indicated 

 by paired white dots in a slight intersegmental furrow, (3) just indi- 

 cated, whitish, (4) as faint pale rings. In the subventral space large rather 

 indistinct hollows (7) alternate with the spiracles, forming perpendicular 

 segmental ridges, reaching to the subventral edge. Caltropes are pres- 

 ent in the last stage only, in little patches on top of the lateral horns on 

 joints 6 to II and large patches on lateral of 12 and subdorsal of 13. 



The first stage does not differ from that of Ettclea delphinii and 

 the mature larva, though differing in sliape, is also adapted for conceal- 

 ment by its coloration. Its defensive armor is even more reduced than 

 in the Euclea mentioned. 



Affinities, Habits, Etc. 



In the shortened horns the larva closely resembles Euclea delphinii. 

 It is more generalized than this species since there are no detachable 

 spines and the bright colors remain. It is more specialized than E. 

 ijidetermina in the shortening of the horns and the alteration in shape, 

 which resembles Parasa chloris, except in the absence of a tail. Our 

 two Eucleas, the Parasa and Adoneta, form a closely allied group. 



The eggs of Adoneta are laid in July and the larvce mature in Sep- 

 tember as usual. The larva is a low feeder and, as several eggs are not 

 infrequently laid at once, several larvns are usually found on the same 

 plant. The bright colors of the larva possibly have little warning effect 

 as the spines are nearly functionless ; but they may serve rather as in 

 the smooth Eucleids to suggest patches on the leaves. 



I am indebted to Miss Morton for the eggs of this species. She 

 has also furnished the material for Dr. Packard's descriptions and thus 

 our present knowledge of this life history is entirely dependent upon her. 



Criticism of Previous Descriptions. 

 Though there are but few references to this larva, it may be said 

 to be well known, owing to the early date of Clemens' writing and to 

 Dr. Packard's very full and excellent account. In my description the 

 lateral horns are located below the spiracles ; the true position is given 

 by Edwards & Elliot. Mrs. Ballard's "strap-shaped lines, buttoned at 

 either end," are to be interpreted as transverse streaks between the 

 paired dots of depressed spaces (i). Dr. Packard describes the "whole 

 life history" in five stages. There are really seven, and Dr. Packard 

 has doubtless been misled by a too hasty generalization from observa- 

 tions of the Notodontidce. The stages which he gives seem to be I,
