and below SM 2 , the centre blue-grey ; cell-spot black, ringed 

 with paler bluish grey ; beyond cell the outer brown band 

 is marked "with a black patch ; band beyond fascia blue-grey, 

 white at costa, traversed by an inwardly dentate dark line ; 

 terminal area a mixture of blue-grey, brovvn, and fuscous, 

 with a bright brown quadrate subapical patch, and traversed 

 by two or three inwardly dentate dark lines, the veins dotted 

 black and pale ; subterminal line ill-defined, followed by 

 black wedge-shaped marks on the interspaces, those below 

 R 3 and M a with a white spot at base ; pale dots at the 

 vein-ends and black lunules between them ; fringe fuscous, 

 proximal half darker than distal. Hind wing fuscous grey 

 with a bluish tinge ; a dark lunulate- dentate postmedian line, 

 followed by a grey band before the darker terminal area ; 

 terminal line and fringe as in fore wing. Underside glossy 

 grey-brown with line and cell-spots darker.

 I know of no species with which to compare this. The 

 palpus is longer than in typical Perizoma, as it occurs in 

 Eui'ope, and the larger size of the insect, very glossy scaling 

 and slightly crenulate termen of hind wing cause it to sug- 

 gest in aspect a Triphosa almost as much as a Perizoma. 

 Yet the latter genus is at present allowed to contain species 

 with even longer palpus than renitens — conjunctiva, Warr., 

 haasi, Staud. (Cidaria) ,basiplaga, Schaus (Psaliodes), &c. — 

 and the last-named is of very nearly the texture of the new 

 species. The antenna of renitens is nearly simple, the face 

 with a slight tuft, palpus rough-scaled, DC of hind wing 

 biangulate, the lower arm moderately produced. 



Perizoma (?) apiceflava, sp. n. 

 <$ . 27 mm. — Head and thorax concolorous with fore wing, 

 shoulders marked with dull yellow ; abdomen concolorous 

 with hind wing; legs blackish, the tarsal joints yellow; 

 tongue yellow. Fore wing dull blackish; edge of basal 

 patch nearly vertical, faintly curved outwards ; inner edge 

 of central fascia bent on SC, then vertical, with a slight 

 projection on M ; the band between yellow, filled with con- 

 fluent fuscous striations, except along the margins, which 

 show as fine yellowish lines ; outer edge of central 

 fascia bluntly rounded in middle, oblique outwards from 

 costa and inwards to inner margin, obscure except from 

 costa to R 1 , where it is followed by a yellowish buff band, 

 traversed by black middle line, and connected above R 1 with 

 a triangular oblique yellow apical patch, preceded by a 

 blackish, externally lunulate-edged costal triangle; marginal 

 line black, interrupted by yellow spots at the vein-ends;
