36 PLATE CCCCVI. 



During one of our fummer excurfions through the northern parts 

 of the principality of Wales, we difcovered by accident a folitary 

 fpecimen of Phalaena Chi, refting among the lichens that encruft the 

 fide of that venerable memorial of Druidical antiquity, the larger 

 Cromlech, at Plus Newydd in the ifle of Anglefea. We obferved it 

 in a perfectly quiefcent ftate, apparently juft as it had emerged from 

 the pupa in the open day time. This was on the 17th day of Auguft : 

 we conceive it requifite to mention this precifely, as the time of its 

 appearance in the winged ftate has been ftated by one writer to be 

 July inftead of Auguft, and that on the authority of the individual 

 fpecimen above mentioned*. 



An erroneous reference among the Fabrician fynonyms of Phalaena 

 Chi, to the work of Albin (Plate 83), had long fince induced the 

 Englifh collectors to confider the Phalasna Chi as a native of this 

 country ; but under this impreffion they miftook a very different infeft 

 for the Chi of Linnaeus. Indeed the infecl figured in Plate 83 of the 

 work of Albiu is no other than the common Sycamore Moth (Phal. 

 Aceris of Brit. Inf.). It is therefore clear, this incautious reference 

 has been productive of confiderable mifunderftanding, and that the 

 Phalaena Chi, though really Britifh, was not introduced with propriety 

 as fuch, till we difcovered it in Anglefea. We fhould however add, 

 that among a number of infe&s found in Yorkfhire, and communicated 

 for our infpeftion by Mr. Rippon, of York, we found an infecl very 

 analogous, and apparently a variety of the fame fpecies, though of a 

 darker colour than our Cambrian fpecimen, which in this refpecl: 

 accords extremely well with the Linnaean exprefiion, " alis canis." 

 It fhould be remarked, that Geoffroy, who defcribes Phalaena Chi, 

 as an infe6l by no means uncommon in France, tells us, it varies 

 much in fize, and fpeaks of varieties that are reddifh, and others
