i;nl>coslal vein a little lie\oiiil luidilU' to before miililie of inner inarijiu, curvej, 

 and .slii,'btly bent on median vein ; outer line pinkish oclireous, curved from 

 costa before apex to three-fourths of iuuer margiu, with a distinct but thin 

 ferruginous line on its outer edge, followed below middle by a blackish deutated 

 shade in the dark grey marginal area; a whitish semicircular apical blotcli, 

 inwardly edged by first a subcostal, sharply angled, white-edged black line, and 

 then by a curved line to outer margin at vein 5, the angle at top and the upper 

 and lower ends of the curved sjiace filled in with dark grey ; cell-spot black, 

 white-edged; marginal line finely black, interrupted by white dots at the vein-ends ; 

 fringe pale grey. 



lliiuhcing : jiale grey, with a brown b;ir at base and a line dark grey straight 

 autemedian line ; cell-spot white ; marginal line and fringe as in forewing. 



Underside j>ale grey, brown-sjieckied, with a dill'nse dark apical jiatch uxi 

 forewing. 



Head, thorax, and abdomen grey ; basal segment of the last with a broad 

 brown ring. 



Expanse of wings : 28 mm.

The hindwing j)ossesses the fovea at base between costal and suticostal veins, 

 but no trace of black tuft from sides of abdomen, nor woolly hair at base of 

 hindwing beneath ; but this last, as the insect is not ijuite fresh, may have been 

 rubbed away. Otherwise it is wonderfully like typical iiiyricomata. 



98. Thysanopyga longistria spec. nov. 



Forfifiiiq : ash-grey in basal half, pale brown in outer, covered with long, 

 slender black striae, excej)! in the brown costal area beyond middle ; an indistinct 

 curved dark line near base marked by black dashes between the veins ; a plainer 

 continuous black line just before the middle, with the black cell-spot on its outer 

 edge; an outer brown line at three- fourths, jilainest on inner margin; an interrupted 

 black marginal line ; fringe brown, with a dark dividing line. 



Ilindicing : brown, with only the basal third grey ; the whole wing striated. 



Underside dull whitish, with a smoky fuscous border, which is jialer towards 

 margin, and twice as broad on forewing as on hindwing. 



Head, thorax, and abdomen above brownish grey ; venter and legs whitish.

91). Thysanopyga suflFecta Warr. and ab. distincta nov. 



This species, described in .\i>r. Zoo/, xi. p. I'-Tj (1',MI4) from a Bolivian c?, 

 turns out to be a dark form of a sjiecies (dosely allied to T. iiit/ricomnfa Warr. 

 from ('hiri(iui, and which also occurs in Feru, but larger and darker ; it may in 

 all cases be distinguished from that insect by the wider distance between the 

 median and outer lines, this latter being less strongly concave than in nigricomata, 

 and the median line less oblique. The woolly hair on Ijasal half of hindwing 

 beneath, concealing the foveal slit, and the lateral tuft of black hair on abdomen, 

 are equally consjiicuous.
