sexes of -wliicli he has figured in his Sammhmg Exotischer 

 Schmetterlinge, Vol. Ill, tab. 32. Hilbner has divided the 

 genus Limacodes into several other genera, founded upon the 

 coloration of the wings, etc., but not upon characters derived 

 from the larvae, few of which were known to him ; and it so 

 happened that he has got fjr another Strehlota an insect 

 which I am confident is not a Limacodes at all. 



A young Dr. OEmler of Savannah, son of a deceased corres- 

 pondent of mine, has lately sent to me for examination a col- 

 lection of drawings, made by old Mr. John Abbot of Georgia, 

 one hundred and sixty-three in number, representing butter- 

 flies, sphinges and moths of that State, with the plants on which 

 they feed. They are not very correctly done, but in general 

 are enough like the original to be recognized, with perhaps a 

 few exceptions only. Among these there is a very good col- 

 ored figure of the saddle-back caterpillar, and very poor repre- 

 sentations of the moth and chrysalis. The moth, however, 

 exhibits one characteristic, which, in your specimens, and in the 

 one from Ohio, is only partially developed, — that is, a large, 

 snow white spot extending from the inner edge of the upper 

 wings towards the middle of each "wing. Now in your speci- 

 mens there are two little white dots, instead of each one of 

 these sj)Ots, neither of which dots touches the inner edge of 

 the wing. Your specimens show also a white dot on each fore- 

 wing towards the tip, but these are omitted in Abbot's draAving. 



By the way, what plant was it on whicli were the saddle- 

 back's cocoons that you sent me ? [ Celastrus scandcns.
