CCENONYMPHA TYPHON, ETC. 107 



Lake Winnipeg, to which, believing it to be a new species, he gave 

 the name Coennni/mpha innrnata. Scudder [Butterflies of Eaatern 

 United States) also treats it as a distinct species. The late Jenner 

 Weir, however, in an article on the Ehopalocera of Hudson's Bay 

 [Entom., vol. xvii., p. 50), treats it as a var. of C. tiiphou. At present 

 I am not prepared to express an opinion as to which view is the correct 

 one. To do so would require a careful comparison of American 

 specimens with European ones, and this I have had no means of 

 making. I should, however, expect that Mr. Weir, who was able to 

 make the comparison, and whose acumen is known to all, was right, and 

 his view certainly receives support from Edwards' description. In 

 this the male is said to be ochrey-brown on the upper side, the disc 

 somewhat lighter, and the costal margin of the fore-wings and inner 

 margin of hind- wings greyish ; there are no spots above or below. 

 On the underside the outer area of the fore-wings is grey, the 

 hind- wings are grey with a slightly greenish tinge, and darker from 

 base to middle. The female is wholly dull ochrey-yellow. Mr. Weir 

 says {I.e.) of the variety, as he considers it: — "They are like the 

 British C. daviisi, but even less marked with ocellated spots ; indeed 

 on the upper side of the wings of two specimens I cannot discover any 

 markings." Provisionally I am disposed to think that the form is not 

 worthy of differentiation from var. laid ion.

 may be tabulated as follows : —

An Instrument to be used as an aid for Setting the Smaller 

 Species of Lepidoptera. 



By J. A. CLARK, F.E.S. 



One often hears lepidopterists explain that they do not collect the 

 smaller species of Lepidoptera because of the difficulty of setting them, 

 and the older collectors often hint that their eyesight is not sufficiently 

 good to set them with advantage even if they did collect them. 



Now that the march of science is necessarily sweeping away the old 

 landmarks, and that the old terms Macro-Lepidopteea and Micro-Lepi- 

 DOPTERA are practically (and I may add really) meaningless, and have 

 to give way to Obtect^e and Incomplete, representing respectively the 

 more highly and less highly evolved of the Lepidoptera, some large 

 and some small species being included in each group, it will become 

 more necessary than ever that observant and intelligent entomologists 

 should study simultaneously those species which show close alliance 

 one with the other, whether they be large or small in size. 



I have for many years collected the smaller species of Lepidoptera, 

 but have recently found the necessity of obtaining some aid to my
