JANUARY, 1860. 105 



sides, very short, scarcely one-half as long as the anterior 

 wings, rather thick, obtuse, and roughened with scales. 

 Maxillary palpi none. Labial palpi extremely short and 

 slender, much separated.* Tongue naked and scarcely as 

 long as the anterior coxa?.* 



C~9*-//>h A. splendor if erella.\ Head golden. Antennae fuscous, 

 tinged with golden. Foi*e-wings, from the base to the 

 middle, leaden-gray, with a splendent lustre, and from the 

 middle to the tip golden, with a broad, nearly straight, 

 metallic, silvery streak, extending from the costa near the tip 

 to the middle of the wing, and dark-margined on both sides. 

 This is nearly joined by a dorsal streak of the same hue, 

 almost opposite to it, with converging dark margins, and 

 with a blotch of dark-brown scales adjoining it behind. In 

 the costo-apical cilia is a short, blackish-brown streak, parallel 

 to the dark margin of the silvery costal streak. 



At the tip is a black, apical spot, with metallic, silvery 

 scales in its centre, and a few silvery scales in the cilia above 

 and beneath it. A blackish-brown hinder-marginal line in 

 the cilia, interrupted by a silvery streak in the cilia beneath 

 the apical spot, and the cilia yellowish-brown. Hind-wings 

 leaden gray : cilia yellowish-brown.

f There is a wonderful superficial resemblance between this insect and 

 Cemiostoma scitella, but the dark lines in the cilia are mAspidisca splendori- 

 ferclla represented by only a single line, which projects straight out at the 

 apex, starting from a black apical spot, which is bordered internally by two 

 short silvery streaks, one above and one below, which, by their union, form a 

 silvery semicircle, separating the apical black spot from the rest of the wing ; 

 the basal portion of the wing is glossy pale-gray, not with the decided bluish 

 tinge we find in C. scitella; a little beyond the middle are two obliquely- placed 

 silvery streaks, sloping posteriorly, and forming, by their union, an augulated 

 silvery fascia; the space between them and the subapical silvery arch is tawny. 

 Exp. al. 2 lines, or sometimes rather less. 



I had the pleasure of breeding two specimens of this insect in the spring of 

 1860, from pupas sent me by Dr. Clemens, October, 1859. (See ante, pp. 23, 

 31, 32.) H. T. S.
