When discussing the relationship of “ Cryptolechia Z. and its allies” [Ins. Life 
2150-1 (1889)] Psilocorsis Clms. was sunk as a synonym of Cryptolechia Z., from 
which Machimia Clms. was separated thus : 
FW: 2-3 adjacent at origin= Cryptolechia Z. (Psilocorsis Clms.). 
FW: 2-3 remote at origin = Machimia Clms. 
This method of distinguishing Psilocorsis from Machimia was indicated by Clemens 
[Pr. Ac. Nat-Sc. Phil. 12 211-3 (1860)], who also found points of distinction in the 
form of the palpi and the vestiture of the head. ‘The characters hitherto relied on 
still hold good as between Psilocorsis (quercicella Clms.) and Machimia (tentoriferella 
Clms.), but Cryptolechia (straminelia Z.) differs from Psilocorsis and agrees with 
Machimia in that FW: 2 is distinctly more remote from 3 than 3 is from 4, while in 
Psilocorsis FW: 2, 3, 4 are nearly equidistant at origin, or 2 tends to become nearer 
to 3 than 3 is to 4, and the palpi differ in the median joint being “rather flattened, 
smooth, with appressed scales” which slightly overlap and form a narrow furrow along 
the outer edge,

1, Cryptolechia peperita, sp. n. (Tab. IV. fig. 9.) 
Antennae pale brownish cinereous. Palpi creamy whitish, the median joint shaded externally to beyond the 
middle with brownish fuscous, Head creamy white. Thorax brownish creamy. Forewings with the 
costa evenly arched, apex obtuse, termen obliquely convex; creamy whitish above the fold, blending to 
brownish creamy and very pale fawn-brownish outwardly and dorsally, speckled throughout, but especially 
beyond the cell, with abruptly square-ended brownish scale-points; a diffused, transverse, small smoky 
fuscous patch lies at the end of the cell; a less conspicuous one, a little beyond the middle of the cell, 
being diffused and widened upward to the costa, where it merges in a narrow shade of fawn-brownish 
extending to base and apex, a series of brownish fuscous dots lying around the termen ; an outwardly 
curved transverse shade somewhat beyond the cell and a slight cloud beyond the middle of the 
fold are scarcely darker than the brownish creamy surrounding the wing; cilia brownish creamy, 
becoming darker around the apex: underside smoky fuscous, with a terminal series of fuscous dots at 
the ends of the veins. Hwxp.al.25 mm. Hindwings and cilia shining, very pale brownish cinereous, 
sparsely and inconspicuously speckled with single scales of a darker hue; underside paler than the 
forewings, with a terminal series of fuscous dots at the ends of the veins, the costal and terminal areas 
somewhat speckled, Abdomen and Leys pale brownish ochreous, the latter shaded externally with 
greyish fuscous.
