•deduction that the cultivated one is derived from the wild stock? \)r, 

 Clemens states that he bred his species A. isabclla from the cultivated 

 ^rape Isabella, which, if I ain rightly informed, is supposed to be derived 

 from Vitis labrusca. I have bred it from at least a dozen cultivated 

 Tarieties, including Catawba, Hartford Prolific and Concord, but I have 

 also bred it from the wild Vitis coniifolia, so that this instance proves 

 nothing. But Dr. C. records the larva of A. viticordifolieUa from the 

 leaves of 7"! corJifolia only, and I have ne\"er found its mine in any other 

 species or variety. A\'ould there not be a presumption — -if it should now 

 be found mininiJ^ anv cultivated varietv — that that varietv SDrans; from the 

 4ordifoHa stock ? So 1 )r. C. records PJiyllocnistis ritigoidla from the leaves 

 of V. cordifolia only, whilst I have found it in the leaves of a great many 

 cultivated varieties, including those above named, so that it proves no 

 aiiore than A. isabdia; but P. vitifoHella I have never found elsewhere 

 'than in the leaves of V. cordifoliella, and one or two cultivated vines of 

 which I find I have kept no memorandum. 



Some years ago I bought from the gardener of the late N. Longworth, 

 •of Cincinnatti, a grape vine of a variety but little cultivated, called 

 " Longworth's Seedling, No. 20," the origin of w^hich the gardener refused 

 to tell me. The foliage is unlike that of any other grape known to me, 

 and is still less like that of Ampelopsis quuiquefolia, and approaches V. 

 cordifolia. Last summer I found its leaves mined by a larva closely 

 resembling that of A. ainpclopsifoliella, supra, and which I suspect to be 

 the same. I have never found it in the leaves of any other plant, though 

 over a dozen other varieties of grapes grow Avithin a itw feet of the 

 Longworth vine. From it I bred the species described below, which I do 

 not now name,as it may prove to be identical with. A. a iiipelopsifo/ieJ la. The 

 single specimen was a little injured, and the description is therefore in 

 one or two respects imperfect. 



Palpi pale yellowish ? Head and face bright but pale golden, in some 

 lights silvery, tinged with golden. Antennae brown, faintly annulate 

 Avith whitish. Thorax and primaries rich purplish brown, in some lights 

 strongly purple or bronzed ; before the middle of the primaries is a some- 

 ^vhat oblique fascia, which is silvery, or bright but pale golden according 

 to the light, Avidest and nearer to the base of the wing on the dorsal 

 margin, and not constricted on the fold ; a silvery or pale bright golden 

 spot on the dorsal margin, just before the ciliae, and a smaller costal one 

 nearly opposite, and a spot of the same hue at the apex. Ciliae a little
