44 DR. BRACKENRIDGE CLEMENS' LETTERS. 



I ought to say, without meaning however to be compli- 

 mentary, that I have derived the greatest pleasure from the 

 study of your volume of" Insecta Britannica." It is, indeed, 

 the only entomological work of which I can say as much, 

 and on this account alone, I feel no little friendship for the 

 student who has led me so skilfully through the complicated 

 mazes that exist in the group of beings of which it treats. 

 In the account of pleasure received I am still largely your 

 debtor. 



With this note I have likewise posted a paper on our 

 Tortricidce. I fear you will not like it, especially the con- 

 cluding remarks. Permit me to call your attention par- 

 ticularly to the new genus Dysodia, p. 349 



[This was the last I ever heard from Brackenridge Clemens. I 

 had thought his attention had been entirely diverted from 

 Entomology, and was agreeably surprised sometime after- 

 wards to find a series of papers from his pen in the Proceed- 

 ings of the Entomological Society of Philadelphia for 1861 

 and 1862 ; the sight of these papers led to my writing him a 

 letter on the 24th May, 1863, but to that letter I received no 

 reply. I subjoin a copy of that letter. H. T. S.J 



Copy of my Letter to Dr. Clemens, dated May 24:th, 1863. 



I have just been reading with much pleasure your papers on 

 American Tineina in the Proceedings of the Ent. Soc. of Phila- 

 delphia for November and December, 1861, for January and 

 February, 1862, and for March and April, 1862. 



Till I met with these papers I had thought that your Entomo- 

 logical activity had been checked, and I am delighted to find that 

 such is not the case, but that so many new observations have been 

 made. 



From the mode of feeding of the genus Catastcga, which you 

 describe at p. 86, 1 should think that your suspicion that they may 

 belong to the Phycidece is probably correct. 



I trust that your calendar of these larvre, with the indications 

 you have given, will prove serviceable in inducing fellow labourers 

 to work at the same group. 



I believe I must plead guilty to not having yet 7-eplied to your 

 letter of the 29th October, 1860, nor thanked you for your paper 

 on the Tortricidce, sent at the same time.
