AOONTIA LUOTUOSA. 



Plate 01, fig. 1. 



I am greatly indebted to Mr. Howard Vaughan for 

 kindly giving me the opportunity of figuring and 

 describing larvae of this species, as well as for 

 furnishing some interesting details concerning their 

 earlier stages. 



The eggs were laid on the 7th and 8th of June, 

 1868, and hatched on the 16th and 17th of the 

 month. 



The young larvae at first appeared to be veritable 

 loopers, twelve legs only being visible ; but as they 

 grew larger the other legs became apparent, though 

 still in walking they did not use the first pair of 

 ventral legs. 



They appeared to be nocturnal feeders, eating the 

 flowers and seeds, as well as the leaves, of Convolvulus 

 arvensis ; they reposed, lying along and closely em- 

 bracing the stems of the food-plant, close to the 

 ground, and in this position would easily escape 

 observation. 



The full-grown larva is about one inch and a quarter 

 in length, slender, and stoutest in the middle, and 

 tapering a little towards the head (which is smaller 

 than the second segment), and more to the posterior 

 extremity ; the folds and divisions moderately indented 

 on the first four or five segments, but hardly noticeable 

 on the remainder. The two hinder pairs of ventral 

 legs more developed than the two preceding pairs. 



The ground-colour on the middle of the back is a 

 pale greyish-ochreous, brownish-grey, or reddish-grey, 

 the sides being darker and browner ; the dorsal stripe
