Lithina triumbrata sp uov. 



Foreiuings: pale mouse-colour, with three transverse dark gi-ev lines, often verv 

 indistinct; the first at one-fourth, bent inwards below the costa ; the second, the 

 thickest, slightly sinuous, from a little beyond centre of inner margin to costa at five- 

 sixths, below which it is incurved ; third subterminal, parallel to hindniar<rin ; all three 

 are sometimes marked with dark dashes on the veins; fringe concolorous. 



Hioidwinr/s : paler, with a very indistinct darker central shade. 



Head, thorax, and abdomen concolorous ; frontlet whitish ; face and antennae rusty. 

 Underside of both wings alike, glossy pale mouse-colour, with a single curved thick 

 darker shade at two-thirds on each wing. 



Expanse of wings : S, 40 mm. ; J , 36 mm. 



Several of both sexes from Cashmere.

For the identification of Ox. mixtata Guen. I am indebted to I\Ir. Schaus. That 

 expulsaria Wlk. is identical with mixtata Guen. I think is certain. 



The form alexonaria Wlk. is the reddest of all, and most, if not all, the 

 rxamples of it that have come under my observation are from Jamaica, whence also 

 proliably Walker's type. Guenee's transitaria, the locality of which is queried as Brazil, 

 may be this form. The distinctness of the markings varies much, according to the 

 amount of dark reddish suffusion. 



Sericosema gen. nov. 



Distinguished froiu SdiJosemn, with which it has been hitherto placed, by the 

 very much elongated and roughened palj)!, the more closely and shortly pectinated 

 antennae, and the silkier, less varied scaling. The margins of the wings also are not 

 crenulate. 



Type: Sericosema jtUttrnaria Guen. (Seliclosema). 



Trichostichia gen. no\. 



Foreivings: with costa faintly curved; apex rounded; hindmargin curved ; anal 

 angle rounded. 



Hindwings : with hindmargin entire, rounded. 



Abdomen of ^ elongate, as in Ischnopteris Hiib., with hairy expansible anal 

 fnft. Forehead with a blunt conical protuberance; palpi porrect ; fir.st two joints 

 hairy, third short, blunt, with appressed scales ; tongue present. Antennae of 6 

 filiform, slender; hind tibiae very large, swollen, with four short s]iurs. U]>per 

 surface of hindwings shaggy with hairs, which form a dense tuft near the base of 

 the inner margin, and are arranged in double layers along each vein, their direction 

 lieing transverse to the vein, the hairs themselves slightly curved and crisp, and 

 directed towards the base of the wing.
