DESCRIPTIONS OF NEW SPECIES OF SOUTH AMERI- 
CAN GEOMETRID MOTHS. 
By Wiwiiam Warren, 
Of London, England. 
Of one hundred specimens submitted to me for determination by 
Mr. William Schaus, the following proved to be new to science, and 
they are accordingly characterized herewith. The types have been 
placed in the collection of the U. S. National Museum by Mr. Schaus. 
Subfamily MHCOCHRA'TIN 4“. 
POLYSEMIA DIVECTA, new species. 
Fore wing.—W ood brown, freckled with darker brown; costal area 
above subcostal vein with some rough pale green scales to middle; 
lines and scale tufts blackish; first line from one-third of costa, 
bluntly rounded in cell close before the large vertical discal tuft, 
acutely angled basewards on submedian fold, almost touching the 
long basal scale tuft, again angled outwards just above submedian 
vein, then oblique inwards to about one-sixth of inner margin; outer 
hne from two-thirds of costa oblique outwards, bluntly angled on 
veins 6 and 4 and deeply incurved between, bluntly rounded basewards 
nearly beneath the discal tuft on submedian fold and sharply angled 
outwards above submedian vein, to three-fifths of inner margin, pre- 
ceded in its lower half by a slight brown shade which is inwardly 
limited by a fine, more or less parallel line, which above vein 4 is 
obscurely rounded inwards to a black costal streak above the discal 
tuft; submarginal line formed of pale interrupted wedge-shaped 
marks, inwardly filled in with darker scales, between 4 and 6, pre- 
ceded and followed by black scaling; a row of black marginal lunules; 
fringe brown, with inner half darker. 
Hind wing—Without basal line; two antemedian diffuse brown 
parallel lines, sharply dentate on veins; outer line black and dis- 
tinct, acutely dentate on vein 6, thence nearly straight to inner mar- 
gin at two-thirds, preceded below vein 6 by a thick brown shade; a 
row of diffuse pale submarginal lunules, preceded by larger brown
