CARL VON HEYDEN. 



Born January 20th, 1793 — Died January 7th, 1866. 



Six years ago was commenced in the pages of the Stettin. 

 Entomologische Zeitung a series of articles headed with the 

 modest title " Fragments from my Entomological Journals," 

 by Carl von Heyden. These were continued to within a few 

 months of that excellent observer's lamented decease. 



When I last saw him in September, 1865, he told me in 

 allusion to a new Tinea which I had seen in the collection of 

 Dr. Rossler, at Wiesbaden, that he had sent a description 

 of it to the Stettin. Entomologische Zeitung in the last paper 

 he should write, 



I have thought it not undesirable, as a contribution to a 

 monument in memory of the departed, to collect together 

 and arrange in the natural order of the species these notices, 

 and give here those of 23 out of the 98 species which he 

 published. 



I have omitted however in these notices the actual de- 

 scriptions of the larvae, fearing to make the paper too lengthy. 

 When any one finds a larva with the precise habit indicated 

 by von Heyden, it is easy enough then to make reference to 

 the original descriptions ; and the Stettin. Ent. Zeitung is 

 now found in many Entomological libraries in this country. 



These 23 notices now given include the Geometrina, 

 Pyralidina, Crambina and Tortricina ; and I believe will be 

 found to contain much that is interesting. 



The figures between brackets at the end of each notice 

 indicate the date of entry in the journal of my lamented 

 friend. H. T. S.
