TYPES OF TOItTRICINA IN THE NATIONAL COLLECTION. 99 



agrees with the description of C. sinuana (111. iv. 128) ; the other 

 two were indicated as cineraria, Bent., a label bearing that name 

 being pinned in the drawer under the specimens. These last are 

 most certainly referable to C. chrysantheana, Dup., but the type 

 of sinuana, if it is not an aberrant form of C. chrysantheana, is 

 most distinctly not the sinuana of Wilkinson and all later authors. 

 In the same drawer was a series of a Cnephasia over the name 

 incanana, Steph. ("The Scotch Gray T."). The description of 

 this species was found in the appendix to Stephens's ' Catalogue 

 of British Micro-Lepidoptera,'* p. 101. The species is also in- 

 cluded as Cnephasia incanana, Steph. MSS., in the list itself 

 (p. 66, No. 12). There were twelve examples of this species 

 in the series, but only three of these were Stephensian, and, 

 although neither was so indicated, it was not difficult to fix on 

 the type. 



After a close but unsuccessful search through all the available 

 literature to discover further reference to C. incanana, I com- 

 municated with Mr. Eustace Bankes on the subject, but he was 

 unable to refer me to any work wherein the species was men- 

 tioned. When he was in town lately, Mr. Bankes was good 

 enough to call at the Museum, and, when he had made a critical 

 examination of the types of sinuana and incanana, he expressed 

 himself satisfied that the latter was identical with the insect that 

 he and others have always considered to be sinuana, Steph. 

 With regard to the specimens standing as sinuana, he concurred 

 in the removal of the two labelled cincrana, Bent., to C. chry- 

 santheana ; but he was rather- dubious, I think, about referring 

 the type of sinuana to that species also. 



I append a copy of the original description of C. incanana : — 



" Alls anticis cinereo-albidis, fascia basalt rotundata, secimda obliqua 

 media, margineque postico nigro-fuscis. (Exp. alar. 7-8 lin.) 



"Head hoary; thorax and anterior wings pale ashy- white, or 

 hoary, with a few dusky scales ; near the base is a distinct deep 

 fuscous bar, rounded externally, and not reaching to the inner margin ; 

 on the costa towards the middle is a similarly coloured bar, extending 

 across the wing, but not to the anal angle ; this bar is well-defined 

 and bi-angulated on the basal edge, but on the hinder one it is gradu- 

 ally shaded off to the ground colour ; the hinder margin is also fuscous, 

 with a curved black transverse streak, reaching from the costa to 

 nearly the anal angle ; fringe ashy ; posterior wings and fringe pale 

 fuscous. 



"Scotland: Perthshire." 



It will be noted from the above that the subbasal bar is 

 described as rounded externally, whereas of sinuana the descrip- 

 tion runs : " with an incurved deep fuscous fascia near the base, 

 having a tooth without." The italics are mine. Wood's fig. 1003
