" Seeing how variable the species is, this multiplieity of 

 trivial names is hardly matter for surprise. Although 

 considered distinct species in comparatively recent times, but 

 few, if any, entomologists of the present day will be inclined 

 to claim specific rank for the forms now so generally admitted 

 to be aberrations of C. truncata. Centiirnnotata has the central 

 area of the primaries white, whilst in cominanotata the central 

 area is fulvous, and in satiwata the whole wing is suffused 

 with fuscous, but the central area is paler ; all these are 

 modifications of the type form, and there are intermediates in 

 all stages connecting one with the other. Hubner's fig. 305, 

 for instance, which by the way Guenee considers the type of 

 russata, represents a specimen which is neither exactly 

 typical or yet centum-notata, as it has broad bright fulvous 

 bands ; this, however, may be an over-coloured figure, as are 

 many of Hubner's figures. 



" In the \2.x , perfuscata, however, we have a form of truncata 

 which exhibits some aberration from the type in marking as 

 well as colour. The basal two-thirds of primaries are blackish, 

 the external limit being well defined by a white toothed line ; 

 there are also two short white lines on the inner margin near 

 the base. Secondaries fuscous grey, with a pale central 

 transverse line. Guenee's fig. 2, pi. 17 {C. russata var.), is 

 like imnianata, but is not a good representation of anything 

 I have seen. From his description it is evident, however, that 

 perfuscata, Haw., is the insect Guenee refers to. Hubner's fig. 

 445 and Wood's 580 represent modifications of this form ; the 

 latter is like the three upper examples in the series o{ perfuscata 

 you will find among the specimens exhibited this evening. 



" Concmnata, Steph., applies to the Arran form of truncata. 

 In this form the blackish basal two-thirds of perfuscata is 

 broken up, by the interposition of a transverse sub-basal 

 fulvous white-edged band, into a blackish basal patch and a 

 blackish central fascia; this last is further adorned with white
