 before two-thirds, dentate and Innnlatc, with black specks on veins, se|)arated by a 

 slight i)ale space from a uniformly broad blackisli fascia, which is overlaid towards 

 costa by some olive scales ; marginal space beyond olive, with blackish striae, which 

 are interrupted towards apex, so that an obliqne streak from ajjcx and another from 

 costa are formed, of the paler gronud-colour, which slightly interrupts the black 

 fascia between veins o and 6 ; some blackish scales along the base of the very slight 

 excision ; fringe dark olive, with paler base. 



IlindwiM/s : similar. 



Underside of forewings ochreons white, with dcc]i brown striae ; beyond the

Expanse of wings : 32 mm. 



One ? from Nova Friborgo, near liio de Janeiro. 



Superficially like S. comctij'eru Butler, but easily distinguished by the prevailing 

 olive tinge. 



IS". Semiothisa subclathrata sp. nov.

 sjieckled with fown-colonr throughout the basal two-thirds; the lines brown, starting 

 from brown costal triangles, and all marked with brown spots on the veins ; first at 

 one-sixth, angled on subcostal, then vertical; second before middle, incurved slightly 

 iu cell and on submedian fold, followed by the dark brown cell-sj)ot ; third at two- 

 thirds, bluntly angled on vein 0, then nearly straight, but lunular and bluntly 

 dentate to inner margin at two-thirds ; followed by a brown-black triangular costal 

 blotch, the apex on costa, the base produced and nearly touching outer line at angle; 

 fringe concolorous, with an interrupted dark line at base. 



Hinthriiujx : the same, without first line or costal Idotches; fiuge jialer. 



Underside white, with coarse fuscous speckles ; costa and all veins ferruginous; 

 the lines dark biowu, shaped as above, but from the ferruginous costal blotch which 

 represents the brown-black blotch of upperside a straight brown-black line runs 

 to near anal angle ; the marginal area beyond it wholly ferruginous, except the 

 apical area beyond blotch, which is white ; hindwings white, with the lines and 

 speckles brown ; veins and a fascia beyond an undulating brown subniarginal line 

 ferruginous. Head, thorax, and abdomen like wings ; the face and palpi darker. 



Exjianse of wings : tJ, 28 mm. ; ? , 32 mm. 



Both sexes from Santos and Sao Panlo. 



The i has the fovea enlarged; hindmargin of I'orewiugs slightly excavated 

 below apex, more perceptibly so iu the ? than in the i ; luotli of the hindwing 

 moderate.
