new Neotropical Geometridae. 509 



shading distally to it at costa, radials, and near inner mar- 

 gin ; terminal spots black, rather large ; fringe concolorous. 

 Hind wing with the central shade proximal to cell-spot, 

 diffuse and approximated to postmedian at inner margin, 

 receding from it and becoming more slender towards costa, 

 obsolete beyond cell ; discal spot smaller than in fore wing ; 

 postmedian distinct, thickened at base of R 3 andM 1 , followed 

 by a large roundish blotch between radials, and a second 

 near inner margin ; subterminal indicated only by a scarcely 

 interrupted series of dark spots which follows it ; terminal 

 line less broken into spots than on fore wing, yet strongly 

 interrupted at the vein-ends. Underside white, both wings 

 with small dark cell-spot, the fore wing in addition witli 

 traces of a postmedian line, and with a roundish, rather ill- 

 defined subapical cloud.

$ . 44 mm. — Head and body concolorous with wings, 

 faee and oceiput slightly brighter brown. Shape of wings 

 nearly as in the group of commataria y Mssu., fore wing some- 

 what broader than in that species ; brown, slightly tinged 

 with olive, and with scattered blackish scales, especially near 

 base and in distal area, on costa of fore wing, and at inner 

 margin of hind wing; the lines ferruginous, shaded with 

 ochreous ; fore wing with autemedian from one-seventk 

 costa, very oblique outwards to cell, and somewhat dark- 

 ened ; then nearly vertical, incurved on M and indented on 

 SM 2 ; median at before two-fifths, almost obsolete ; post- 

 median from two-thirds costa, parallel with termen through- 

 out, minutely toothed on veius^ the teeth accompanied by 

 dark dots; subterminal from five-sixths costa, nearly parallel 

 with termen, indicated by a series of black dots between the 

 veins, margined distally by small, somewhat lunulate whitish 

 marks ; the dots anterior to R 1 moderate-sized, those between 

 radials large, the posterior ones minute and indistinct, grey 

 rather than black; discal dot small, black, distinct; terminal 

 dots small, black, distinct, especially anteriorly ; fringe con- 

 colorous with wing. Hind wing with no autemedian line, 

 postmedian straight, from inner margin at two-thirds to the 

 fold between C and SC at nearly three-fourths, here weakly 

 angled, but becoming almost entirely obsolete; subterminal 

 spots all small ; terminal dots minute and for the most part 

 indistinct. Underside nearly unicolorous grey -brown, weakly
