1. Cecidoiryia. On this family, the following papers may be con- 

 sulted :

Entomol. V, 1851.

Bergenstamm und Low iFr.), Synopsis Cecidomyiaruin , in 



the Verh. Zool. Bot. Gesellsch. 1876. A synopsis of all the 



literature on the subject; very accurate and complete. 



C. R. Osten Sacken. On the North American Cecidomyidae. — 



In the Monographs of N. A. Diptera, Vol I (a survey of the 



previous publications concerning the classification, habits etc.). 



In an inaugural Dissertation, entitled: Revision der Gallmiicken, 



Miinster 1877, Mr. F. A. Karsch changes the existing nomenclature of 



the Cecidomyidae, in virtue of the principle of priority. What we call 



now Cecidomyia, he calls Dasyneura Rondani; our Diplosis Loew, is 



his Cecidomyia Meigen; Clinorhyncha Loew is to be Ozirhj'ncus Ron- 



daui; Epidosis Loew is Porricondyla Rondani; Hormomyia Loew is Oli- 



gotrophus Latreille. 



The general adoption of these changes does not seem at all desirable. 



2. Ctcid. grossulariae Fitch. In the Monogr. I, p. 7, Mr. Loew 

 stated that this species is an A^plioiidi/Jia, a statement which I repeated 

 on faith, 1. c. p. 189. Dr. Fitch's description renders it evident that his 

 species is atrue Cccidoniijia. It is probable that, in making the above-quoted 

 statement Mr. Loew had in his mind the curopean Cccid. ribesii Meigen, 

 which, as appears from Meigen's description, must be an Ai^phondi/Iia. 



3. Cecid. sa'icis tatatas. „This gall seems to agree in its structure 

 with that of Cecid. scdicis Schrank, on european willows." Bergenstamm 

 & Low, 1. c. p. 71. 



4. „The five kinds of leaf-accumulations and leaf-roseltes , which 

 Mr. Walsh describes and which he attributes to his Cecidomyiae 

 gnaphaloides , rhodoides, strobiloides, strobiliscus, coryloides, seem to be
