NOTES. 



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

 sulted: 



H. Loew. Dipterologische Beitrage IV, lsr,o 



The same. Zur Kenntniss der Gallmucken, in the Linnaea 



Entomol. V, 1851. 

 J. Winnertz. Beitrag zu einer Monographic der Gallmucken, 



in Linnaea Entomol. VIII, 1854; with four beautiful plates. 

 The same. Heteropeza und Miastor, in the Verh. Zool. Bot. 



Gesellsch. 1869. 



The same. Die Gruppe der Lestreminae, in the same volume. 

 Bergenstamm und Low (Fr.), Synopsis Cecidomyiarum , 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 Gallmucken, 

 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 Ozirhyncus 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. Cecid. grossulariae Fitch. In the Monogr. I, p. 7, Mr. Loew 

 stated that this species is an A*f>ltoiulylia, a statement which I repeated 

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

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

 statement Mr. Loew had in his mind the european Cecid. ribesii Meigen, 

 which, as appears from Meigeu's description, must be an Asphondylia. 



3. Cecid. salicis batatas. ,,This gall seems to agree in its structure 

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

 & Low, 1. c. p. 71. 



4. ,,The five kinds of lea-accumulations and leaf-rosettes, which 

 Mr. Walsh describes and which he attributes to his Cecidomyiae 

 gnaphaloides, rlnco:de3, stroluloides, strobiliscus, coryloides, seem to be
