36 PLATE CCCCVI. 
During one of our fummer excurfions through the northern parts 
of the privcipality of Wales, we difcovered by accident a folitary 
fpecimen of Phalzna Chi, refting among the lichens that encruft the 
fide of that venerable memorial of Druidical antiquity, the larger 
Cromlech, at Plas Newydd in the ile of Anglefea. We obferved it 
in a perfeétly quiefcent ftate, apparently juft as it had emerged from 
the pupa in the open day time. This was on the 17th day of Augutft : 
we conceive it requifite to mention this precifely, as the time of its 
appearance in the winged ftate has been {tated 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 Phalena 
Chi, to the work of Albin (Plate 83), had long fince induced the 
Enghth colleétors to confider the Phalzna Chi as a native of this 
country ; but under this impreffion they miftook a very different infect 
for the Chi of Linnzus. Indeed the infect figured in Plate 83 of the 
work of Albm is no other than the common Sycamore Moth (Pihal. 
Aceris of Brit. Inf}. Tt is therefore clear, this incautious reference 
has been productive of confiderable mifunderftafiding, and that the 
Phalena Chi, though really Britith, was not introduced with propriety 
as fuch, till we difcovered it in Anglefea. We fhould however add, 
that among a number of infects found in Yorkthire, and communicated 
for our infpection by Mr. Rippon, of York, we found an infeét very 
analogous, and apparently a variety of the fame fpecies, though of a 
darker colour than our Cambrian fpecimen, which in this refpect 
accords extremely well with the Linnean expreflion, “ alis canis.” 
It fhould be remarked, that Geoffroy, who defcribes Phalena Chi, 
as an infect by no means uncommon in France, tells us, it varies 
much in fize, and fpeaks of varieties that are reddifh, and others
