1903.] 165 



To hira I am indebted for the opportunity of examining some of 

 the original specimens in fine condition, and I find in them the actual 

 character given by lliibner and quoted by M. Ragonot as distinguishing 

 verriicella, Hiib., a reddish wart-like elevation at the first line of the 

 fore-wings. This elevation of red scales, sometimes duplicated, is not 

 placed upo7i the thick black " first line," but just outside and touching 

 it. No such raised tuft of red scales appears upon our well known 

 A. tumidella, Zk., nor upon the very much less known A. rubrofibiella, 

 F. B., and, combined with the different shape of the fore-wings, ample 

 reason seems to be furnished for acknowledging it as a distinct 

 species. At the same time, as it seems to me, the alteration of the 

 name of our well known A. tumidella to Zelleri is unnecessary. 



A detailed description may be desirable. 



A. verruceUa, Hiib. Expanse, 20 nun. Fore-wings rather narrow, purple-grey, 

 basal space whitish-buff with a basal red dot ; close outside the first black line are 

 one, or sometimes two, small tufts of upraised red scales. Hind-wings smokj 

 golden-brown. 



Antennae of the male thread-like, but having a small pointed tuft on the basal 

 joint, and the second joint curved and thickened, red-brown ; palpi ascending, 

 slender, outwardly red-brown, paler within ; head reddish-white ; collar purple- 

 red, with a dull white edging ; thorax and abdomen purple-brown, the latter 

 glistening, and having a paler edging to each segment. Fore-wings elongate, narrow 

 but broadened behind ; costa nearly straight ; apex bluntly angulated ; hind margin 

 gently rounded and rather full ; pale purple-grey, dusted with brown and black ; 

 at the extreme base is a rich red dot above the median nervure ; remainder of the 

 basal space very pale buff, shading into white close to the first line ; this line is 

 thick, black, nearly straight and erect ; touching it is a faint rufous cloud in which 

 are one or two upraised tufts of red scales ; the black scales of the first line itself 

 are also rough and up-tilted ; in the middle of the wing is a large purplish-brown 

 cloud, followed by two black ill-defined discal dots ; second line oblique and obscure, 

 bent inward at a short distance from both costal and dorsal margins, but the inter- 

 mediate portion bowed outwards, and, upon this curve, thrice toothed ; these teeth 

 most distinct upon an interior edging of cloudy black ; hind margin smoky purplish- 

 grey, with a faint row of black dots, closely followed by a black marginal line ; cilia 

 concolorous, glossy. Hind-wings moderately ample, shining smoky-brown, the cilia 

 rather whiter and brilliantly glossy. Female similar, except that the antennae are 

 quite simple. 



On the wing in July and the beginning of August. 



It frequents old oak trees, flying about them at dusk, and has 

 been taken at sugar upon their trunks. 



At present its range appears to be uncertain ; but many speci- 

 mens were taken in the old locality, at first by Mr. McLachlan, and
