with smoky; the junction of the cubital vein with vein 2 is outlined in black 

 forming a V mark and vein 1 in this area is also outlined in black ; the following 

 area is paler, especially in costal half which contains a prominent discal dot; 

 this area is bounded outwardly on costa by a third quadrate black patch giving 

 rise to two lines as before, the inner being subparallel to the preceding lines, 

 the outer more irregular, angled outwardly below costa, then strongly concave 

 opposite the discal spot, forming an outward angle on vein 4, then inwardly 

 oblique to the fold and rounded outwardly to inner margin ; the included area 

 is very narrow for a short distance below vein 2, shaded with smoky and 

 crossed by dark dashes on veins 1, 3 and 4; beyond this line at a distance of 

 about V/2 mm. is a smoky line more or less parallel followed at a short distance 

 by a whitish, crenulate, s. t. line, parallel to outer margin, preceded, especially 

 above and below vein 5, by dark shading ; a terminal broken dark line and slightly 

 checkered fringes ; secondaries pale smoky with discal dot, crossed by indistinct 

 curved, dark, median and subterminal lines shaded outwardly with paler ; distinct 

 terminal broken dark line preceded by pale spots; fringes checkered. Beneath 

 primaries smoky with ochreous blotches on costa accentuating a dark patch 

 corresponding to the third patch of upper side; subterminal markings of upper 

 side faintly discernable ; secondaries as above with markings rather more distinct.

Very similar to curvilinea Hist, but the first subterminal line is 

 well defined and not represented by dots and the discal dot is promi- 

 nent ; the apex of wing is also less rounded. 



Perizoma epictata sp. nov. (PI. Ill, Fig. 20). 



Primaries pale brown, narrowly banded with whitish; an upright white 

 subbasal line ; beyond this a narrow white band with central brown line forming 

 the inner edge of the median fascia ; this white band is straight from costa to 

 cubital vein then bent inward to inner margin where it touches the white sub- 

 basal line, the included triangular space being brown ; median area brown, cen- 

 trally whitish, especially around the discal dot and above inner margin, crossed 

 by three faint wavy lines, one before and two beyond the discal dot, the inner 

 two tending to coalesce ; the outer margin of the median area shows a prominent 

 bulge between veins 2 and 4 with a slight inward angle on vein 3 ; a narrow 

 white band edges the median area outwardly, crossed by a central dark line; a 

 dentate white s. t. line beyond which the terminal area is gray shaded with a 

 smoky suffusion below apex; fringes checkered ochreous and smoky; secondaries 

 whitish, slightly smoky, with indistinct median and subterminal dark curved 

 lines, a terminal dark broken line and checkered fringes. Beneath primaries 

 smoky, costa and terminal area paler; a dark spot on costa near base and discal 

 dot; postmedian and s. t. lines of upper side repeated faintly, accentuated on 

 inner side by smoky shades; secondaries whitish, sprinkled with smoky, a dark
