1 S from Tncuman, Argentina, UtiU m., January and February I'jOo 

 (Steinbach). 



The whole insect has a furry aiipearance. 



A ? from Salta, N. Argentina, 40 mm. in expanse, sent by the same collector, 

 belongs apparently to the same species. The undersides are precisely similar ; 

 above, the ? , which is not quite so fresh as the S and lacks its furry appearance, 

 has hardly any olive tinge, the ground-colour being dull brick-red covered with 

 fine black striae ; the three bands are in precisely the same position, but blackish 

 and distinct, and the outer line is marked by distinct black spots on the veins, 

 but neither it nor the inner line shows any signs of white dashes ; the exterior 

 band is more phiinly dentate ; fringe brick-red. The hindwing differs in the 

 same way. 



06. Prostoma stabilis spec. nov. 



Differs from P. fragilis Warr. in the shorter and darker wings ; the pale 

 ground-colour is qnite hidden by reddish fuscous suffusion covered with dark 

 striae ; the wavy black lines are placed as m fraiiilis, tiie outer being finely edged 

 with wiiitish, but there is no pale space before it, as in that species ; the black 

 spot on vein 6 in the subniarginal line is absent; the darker hindwing shows a 

 whitish blotch at anal angle. 



Underside with botii cell-spots large and dark, ami the outer line black ; the 

 whole marginal tliird of hindwing washed witii whitish. 



Head, thorax, and abdomen reddish fuscous. 



In the ? the reddish tint is absent. 



Expanse of wings : 20 mm. 



1 cJ, I ? from La Oroya, R. Iiiamliari, Caraliaya, Peru, 3100 ft., November 

 and December 19o5, wet season (Ockenden). 



The antennae of the cJ are simple in both species. 



97. Thysanopyga deprivata spec. imv. 



ForririiKj : grey; tlie costal streak ochreons speckled with fuscous; first line
