130 HAUSTELLATA. — LEPIDOPl'ERA. 



regarded wltli suspicion, and their true locality, if possible, pointed 

 out; otherwise we must continue in wilful ignorance to the end of 

 time, and truths that might shine forth as brilliantly as the orb of day 

 will be for ever shrouded in the obscurity of impenetrable darkness. 

 An earnest desire to give the insects of this country free from such 

 admixture has induced me to express my doubts upon the origin of 

 particular species by placing them in a note, when I had not oral or 

 other testimony for admitting them into the body of the page ; and 

 even in the latter cases to give my suspicions when there has been 

 cause for doubt ; and I may here observe, that as the descriptions 

 of the insects herein are all corrected and compared with the objects

Somewhat allied to the last : anterior wings plain griseous, with an ohlique^ 

 straight whitish streak from the apex to nearly the base of the thinner margin^ 

 accompanied anteriorly with two dusky streaks, and posteriorly with about four 

 more obsolete ones of the same colour, the hinder margin itself slightly rosy ; 

 the disc with a single black spot : posterior wings brown, rather deepest at 

 the base, with a pale ochraceous streak towards the anal angle, which is still 

 paler: head as inDe. Celerio: thorax slightly olivaceous, with a faint dorsal, and a 

 whitish-ash lateral line, and a pale luteous one between, on each side; abdomen 

 with a broad faint dorsal silvery-white streak, and an obsolete golden one on 

 each side. 



Dr. Leach also obtained a specimen of this insect, which is in all probabiUty syno- 

 nimous with the Sph. Celaeno of Esper, from Dr. Lettsom's cabinet, and a 

 second was obtained by myself from an old collection which was broken up 

 about fifteen years since ; but I am decidedly of opinion that neither of them 

 have any claim to be considered natives of Britain. 



in which it was found had been unshipped and packed about eleven months ! 

 yet it cannot be considered indigenous, any more than the Blattce giganteu, 

 Americana, Madera, orientalis, &c., which occur in Britain (the latter espe- 

 cially, abounding in the lower apartments of most houses throughout the 

 metropolis). The Prionus accentifer, OHv., (Acrocinus, Illig.) I have seen at 

 large more than once, and various other exotic species, such as Callidia fulmi- 

 r.ans et fascial um. Lamia dentator, Stenachori <iuadrideniatus et spinicornis^ 

 Tetraopes tornutor, Sec; as weU as a fine Chinese Conocephulus, which subsisted 

 upon tea, and continued alive nearly four months in my possession ; but neither 

 of the above can be considered indigenous, and doubtless the Ccruml)i/x liiterattts 

 of Donovan has no pretensions to yuch origin.
