130 Lord Walsingham on 



ligurc (Trans. Am. Ent. Soc, ii., pi. viii., f. 78), as well 

 as from specimens in my possession, in that the first of 

 the two dark markings on the fore wings is distinctly 

 and throughout its lower edge connected with the dorsal 

 margin instead of being entirely separated from it. In 

 this it agrees with Hiibner's figure, and there can be no 

 doubt that the two species are quite distinct. Kobinson's 

 Conchylis himaculana is therefore still entitled to retain 

 its place in our lists. 



Head, palpi, thorax, and fore wings rich brownish ochreons, the 

 outer sides of the palpi, the antennae, and the extreme costal mar- 

 gin (in fresh specimens) shaded with chestnut-brown. A rich 

 chestnut-brown triangular blotch pointing obliquely outwards from 

 the middle of the dorsal margin, its apex reaching the costa beyond 

 the middle is followed by a lunate blotch preceding the apical mar- 

 gin, its concave upper edge facing a small oblique oblong ovate 

 subcostal spot. Hind wings fuscous. Expanse, 14 mm. 



Conchylis sonorcB, n. s. 



Head and palpi whitish ochreous, the latter, except on the apical 

 joint, ferruginous-brown on their outer sides. Antennae whitish 

 ochreous. Fore wings whitish ochreous, much suffused with shin- 

 ing silvery scales. The extreme costal margin ferrugineus-brown 

 at the base ; in some specimens a ferruginous -brown line runs from 

 the base nearly half the length of the wing immediately below and 

 parallel to the costa. A ferniginous-brown central streak arises at 

 the base of the wing, not contiguous to the dorsal margin, and 

 dilating outwardly reaches nearly to the middle. Beyond the 

 middle is a small ferruginous-brown costal spot partially blending 

 with an oblique shade or streak of the same colour, which tends 

 oiitward towards a point below the centre of the apical margin. An 

 elongate triangiilar ferruginous -brown spot precedes the anal angle, 

 to which its point almost attains, while its base is separated from 

 the dorsal margin. Before the apex there is a second small costal 

 spot, and along the apical margin a distinct streak, both ferruginous- 

 brown. Expanse, 15 mm. 



This species, of which I have received from Mr. 

 Morrison several specimens from Sonora, in Mexico, all 

 remarkably constant in the position of their markings, 

 dift'ers from C. dorsimacidana, Eob., and C. pwmptana, 

 Eob., to which it is nearly allied. 



The most noticeable distinction is to be found in the 

 complete separation of the basal streak from the dorsal
