striped ones, doing violence to all his notions of symmetrical arrange- 

 ment. He would have rejected the blue taw with abhorrence. What 

 does the word " BrcutJiis Hiibner " mean, if not that the genus Bretithis 

 was created by Hiibner, and that his definition includes the species sought 

 to be placed under it ? If it has an}' other meaning I am ignorant of it, 

 and if it does mean that it is false. This is a fair sample of the uses to 

 which Hiibner s absurd and worthless Catalogue has been put. Very few 

 Lepidopterists in this country know anything of Hiibnefs books, and 

 most are disposed to accept in some degree the dicta of any one who sets 

 up to reform the nomenclature. But if reform be needed, which is 

 very questionable indeed, it is not to be brought about by lugging Hiibner 

 into the arena. To go back at this time of day to the Verzeichness is to 

 go back to the balls and tops and games of school-boys. 



NOTE ON DATANA PERSPICUA G. & R. 



BY A. R. GROTE, BUFFALO, N. V. 



Since the original illustration and description of this species, ten years 

 ago, in the Proceedings of the Entomological Society of Philadelphia, it 

 has not been noticed, except by the late Mr. B. D. Walsh, in the same 

 Proceedings, vol. 5, p. 194-5. 1 have been since last year indebted to 

 Prof. C. V. Riley for a number of specimens of perspicua, raised from 

 larvae found on Sumach. It is enough to say that the specimens bear out 

 the specific validity of a form which is perhaps the most easily recognized 

 among the difficult species of this genus. I was able to separate the 

 imagos of a number of the species bred by Prof. Riley, by the characters 

 laid down by the late Mr. Robinson and myself in our revision of the 

 genus. Specimens of contratta, integerrima, ministra and persplcua were 

 sent me by Prof. Riley ; no true specimens of angusii were included. I 

 observed the larva of integerrima at Detroit, August 13, and again on 

 Grand Island, Niagara River, Aug. 19, apparently nearly full grown. I 

 have not had hitherto any specimens of perspicua, before receiving those 

 sent me by Prof. Riley, who will, I hope, give us some observations on 

 the genus before long. I am glad also to be able to find that the facts
