shortly by a weaker, more diffuse line ; postmedian much as 

 in fore wing. Underside rather paler, with indistinct lines ; 

 cell-spots distinct, terminal spots more conspicuous than 

 above.

 {M. G. Palmer). Type in coll. L. B. Prout. 



Nearly related to C. pallidicosta, Warr. Nov. Zool. xiv. 

 p. 241, of which it may possibly prove a form ; smaller, 

 duller, the costa less conspicuously j)ale, the fringe apparently 

 not pale j'-ellow at the extremity (but slightly damaged), the 

 hind wing less strongly toothed at K\ 



Trlchoclystis vhomhipennis, sp. n. 



^ . 20 mm. — Head and palpus dull ochreous, the latter 

 marked with fuscous along upper side. Antenna pale 

 ochreous, spotted above with fuscous. Body pale ochreous, 

 mixed with fuscous ; abdomen densely tufted with long hair 

 beneath. Fore wing shiny (almost greasy-looking) ochreous 

 grey, suffused along costa and termen with fuscous ; basal 

 patcli small, fuscous, widening costally ; median band 

 fuscous, of uniform width, smooth-margined, its proximal 

 edge from costa at almost one-third, very gently incurved, 

 distal edge from costa at two-thirds, gently outcurved in 

 costal half, here somewhat darkened ; obscure dark sub- 

 terminal shading costally and between the radials; terminal 

 line dark, interrupted at vein-ends ; fringe grey, apparently 

 dark-spotted at vein-ends (defective). Hind wing short, 

 termen truncate from C to li^, here bluntly right-angled, 

 thence nearly straight (somewhat sinuate) to tornus ; pale 

 grey, more tinged with ochreous in distal and inner marginal 

 part; faint indications of median, postmedian, and terminal 

 dark bands starting from inner margin. Underside greyish, 

 weakly marked, fore wing with faint curved postmedian line 

 and faintly dark terminal shade, separated by a vague pale 

 band. 



San Antonio, W. Colombia, 5800 feet, December 1907 

 (J/. G. Palmer). Type in coll. L. B. Prout. 



Apparently referable to the genus Trichoclystis as defined 

 by AVarreu (Nov. Zool. xi. p. 535), all the generic characters 

 which he gives being well developed ; the agreement with 

 2'epliroclystia (^Eupitkecia) in venation is, however, confined 

 to the fore wing (and probably the female hind wing — at 

 present unknown) ; in the curious rhomboid male hind wing 

 the cell is strongly produced anteriorly (the reverse of the 

 form so common in Larentiid genera), SC^ arises from the
