believe that the same species mines leaves of Hhus toxicodendron, one of the Anacar- 

 dacea; aud also those of ^sculus glabra beloDgiug to the Sapindacece. He then pro- 

 eeeds to describe another species, coryUella, also very uearly allied to gnttifinitcUa but 

 feeding on Corylus amcricana, and his variety ostrywella mining Ostrya riryiniva is said 

 to bear the same relationship to coryUella as cesculisella bears to guitifinitella. It is 

 more possible to conceive that this is ouly a variety, since the two food plants beloug 

 to the same family. He gives a table showing the differences between the larv;e of 

 these four species, or varieties, which he finds to be constant and striking. It would 

 seem perhaps to be a somewhat arbitrary proceeding to raise to specific value an in- 

 sect described as an undistiuguishable variety. I shall content myself with drawing 

 special attention to these two descriptions of supposed varieties in the hope that at 

 some future time those who have the opportunity of breeding the species will clear 

 up the doubts that certainly exist in my mind about them. 



Lithocolletis atomariella, Z. 



Zeller placed atomariella in his cabinet heiweeu. jyastorella Z. aud 2)opuUfoUeUa Tr., 

 and the differences, although slight, are sufficient to separate it from both. 



Lithocolletis salicifoliella Chamb. 



This species is also very closely allied to, but distinct from, paslorella Z. and popn- 

 lifolitUa Tr. It is in all probability identical with the larva described under the 

 same name by Clemens. 



Lithocolletis anibrosiella Chamb. 



A group of species allied to this rypical form has been described by Chambers and 

 Frey and Boll. These include ignota V. &, B., hcleanthivoreUa Chamb., hostotiica F. & 

 B., elephantopodella F. & B., amana F. & B., actinomeridis F. & B., and nobilissima F. 

 &. B. (the latter can only be treated as an MS. name, no detailed description having 

 been published), all feeding upon various Compositor The name ambrosiireUa was 

 corrected to ambrosiella by F. & B. (Stett. Enr. Zeit., XXXIX, 267). L. ignota F, & 

 B. seems to be the same as heleanthivorella Chamb., as suggested by Chambers — ignota 

 takes precedence. 



I have not sufficient material at hand to determine whether the other species 

 should, or should not, be retained as distinct. For the purpose of the revised index 

 and until more evidence is forthcoming to identify them, they must certainly be re- 

 spected.

GENERAL NOTES. 



HONORS TO AMERICAN ENTOMOLOGY. 



Professor Eiley, chief of this Division, has just been elected an hon- 

 orary fellow of the Entomological Society of London. Br. Riley is the 

 third American who has received this honor, the others being Dr. H. 

 A. Hagen of Cambridge, who was elected in 1803, and Dr. A. S. Pack- 

 ard, elected in 1884. The Transactions for 1888 show that there are 

 only ten living honorary fellows. 



Professor Riley has also been created chevalier of the Legion of 

 Honor by the French Government. This action had no reference to
