[My friend Mr. Buckler found a larva in the summer which pro- 

 duced my Lithosia stramineola. He kindly sent me a beautiful 

 drawing of it, which 1 forwarded to M. Guenee, with reference to 

 which he says, in a letter recently received from him, as follows : — 

 "The first sight of this drawing caused me to think that I was right in 

 considering L. stramineola as a variety of L. griseola. A comparison 

 with the preserved larvae of this species which I possess confirmed me 

 in my opinion. 



" The two caterpillars do not differ at all, either in form, hairiness 

 or colour, except that in the drawing which you have sent me the 

 dorsal spots are redder than in the specimens, and rather larger and 

 more distinct. In the larvae of L. griseola, of which I have three spe- 

 cimens, one has spots only on the first and last segments ; the two 

 others have the spots upon all the segments, but those upon the inter- 

 mediate ones are small and almost linear. You Vill perceive from 

 this that the spots vary in different individuals ; and should Mr. 

 Buckler rear a considerable number, he will probably find some 

 amongst them with the intermediate spots smaller than in the one 

 which he has figured. 



" I have now given you my opinion of your drawing ; however, if I 

 had seen the larva in nature, I could have given a more decided 

 opinion, as certain slight, but important, characteristics may have 

 escaped the notice of your friend, which would either L. show strami- 

 neola to be a distinct species, or positively prove that my first opinion 

 was correct." — H. D.]
