COSSIDAE 4 
GIVIRA LUCRETIA sp. nov. (PI. IV, Fig. 12). 
Head and thorax gray, patagia sprinkled with whitish; primaries milky 
white shaded with deep brown; costa from base to apex with a series of small 
brown dots, cell with a few faint brown striations, otherwise immaculate; dis- 
cocellulars whitish; beyond the cell between veins 2-6 a broad smoky-brown 
shade cut into a series of semiquadrate spots by the pale veins; at the inception 
of vein 2 this shade bends towards inner margin forming similar spots between 
the anal veins and becoming lost in a diffuse brown shade extending along inner 
margin from base of wing to anal angle, leaving the extreme margin at base of 
wing contrasting white; this shade is slightly broken by slight white striations; 
terminal portion of wing whitish with faint brown striations; ends of veins 
bordered on each side by dark dots, fringes pale, checkered with brown. Sec- 
ondaries pale smoky with darker reticulations and intravenular dots as on pri- 
maries. Beneath primaries smoky, paler along inner margin, secondaries whitish, 
both striate with smoky brown especially terminally. Expanse 27 mm.

The species is allied to cornelia N. & D., differs in the much 
greater prominence of the dark band beyond cell and the more promi- 
nent striations of secondaries.
