528 Mr. E. Meyrick on Australian Leindoptera. 



lAl.— Notes on Synomjmy of Australian Lepidoptera described 

 hy Mr. Eosenstock. By E. Meyrick, B.A., F.E.S. 



In the ^Annals and Magazine of Natural History' for 1885 

 (vol. xvi. pp. 376-385, 421-443) is a paper on Australian 

 Lepidoptera by Mr. Rosenstock, Avhich requires a good deal 

 of correction in order to make it available for scientific use. It 

 appeared to me therefore desirable to embody in a short note the 

 principal alterations which require to be made in respect of the 

 Geometrina and Microlepidoptera, to which most of my atten- 

 tion is given. 1 may add that, as Dr. T^ucas (the collector of 

 the insects described) has placed in my hands types of the 

 greater number of his species, I am enabled in most cases to 

 speak Avith confidence of the identification of those described by 

 Mr. Eosenstock, of which the descriptions are not always suffi- 

 ciently precise. Mr. Rosenstock expresses an opinion that I 

 have overlooked descriptions of several species, and in some 

 cases (only one is mentioned) described neuration wrongly ; 

 this is possible enough, but by reference to the notes hereafter 

 following it will be seen that in every instance quoted he is 

 mistaken. 



Messatts, Walk., is stated to be distinct from Endotrichaj 

 but no points of difference are given ; without these it is ob- 

 vious that no attention can be paid to the assertion. The 

 species {E. injrosalis., Gn.) agrees with Endotricha in every 

 character known to me, as I have elsewhere pointed out. 



Scojmla segestusalis, Walk., is, as admitted, too much 

 worn for recognition, and was intentionally neglected. I 

 should add that my paper on Australian fyralidina did not 

 profess to be exhaustive, and that several probably good 

 species described by Walker were purposely omitted for want 

 of specimens for examination. 



IsoiJteryx m'tidalis, Walk. Stated to be overlooked by me ; 

 it will be found in the genus Musotima^ and has no connexion 

 with Isopteryx. 



Scoparia pusilla^ Ros. I have not seen an authentic speci- 

 men, and cannot recognize this, but think it may probably be 

 S. spelcea, Meyr. 



The genus Thalaina, Walk., is placed (following Walker) 

 among the Liparidas ; it belongs to the Boarmiadas. 



The species included in the genera Fidonia^ Panagra^ and 

 Dasyuris have in no instance any connexion with those 

 genera. 



G. lucidulata, Walk., is stated " to present all the cha-
