346. Pergama plenilunata spec. uov. 



Intermediate in point of size between P. traiUii Butler ( = iiinthanaria 

 Obertli.) and Pero Miiposarid Gnen., both of which it greatly resembles super- 

 ficially. It may be distinguished by the following points : the outer line in the 

 forewing is nearly straight, not strongly incurved in its middle third ; tin- diseal 

 spot is a grey circle with a black edge, and is preceded by an oblique orange blotch 

 from the costa; on the underside the pale area at anal angle occupies the whole 

 width of the interval between outer line and hindmargin, and above touches vein 4; 

 in traillii it lies on the hindmargin, reaching only half-way to outer line, and above, 

 not beyond vein 3. 



Expanse of wings : 44 mm. 



1 S from R. Inambari, E. Peru, imiOm., July lOoii, rainy season (Simons). 



347. Pergama semiusta ab. ? latifascia nov. 



Along with si.\ typical examples of P. semiusta Butler from Santo Domingo, 

 Peru, taken in November 1901, there was sent one S which differs so considerably 

 that it migjit well be considered a distinct species. The points in which it thus differs 

 are shortly as follows : all tlie purplish grey scales of tlie type, both above and 

 below, have become dull brick-red ; the outer line of the forewing is much nearer 

 the hindmargin, so that the central fascia is much wider; the dark shading 

 which usually precedes this line is entirely lost, the line itself being simi)ly edged 

 with black, while above the median, instead of running, as in the type, nearly 

 straight to costa, it forms three outward curves as strong as those below ; the line is 

 followed by a pale greyish space which merges gradually into dull brick-red befijre 

 the margin, without any of the usual markings. From the greater breadth of the 

 central fascia, the absence of the normal shading, and the briok-red coloration, the 

 insect assumes quite a different aspect from normal examples of semiusta. 



348. Perusia complicata spec. nov. 



Forewiiiy : yellow, speckled and slightly tinted with rufous grey, the veins 

 marked with the same colour, especially towards hindmargin ; basal i^atch 

 triangular, rufous and fuscous, liardly reaching the costa, its outer edge twice 

 curved and indented below median vein, edged by an obscurely double dark line 

 reaching middle of inner margin ; a similar-coloured postmedian fascia, its inner 

 edge marked by a double thick zigzag line, angled outwards on veins 3, 4 and 6, 

 inwards on vein 5, its outer formed by the submarginal line, which is acutely angled 

 on vein 7 and on veins 2 and 3, close to hindmargin, incurved basewards between 

 7 and 3, leaving a yellow space ; a few dark scales along hindmargin, which is 

 faintly lient outward at middle; fringe yellow; cell-spot grey, linear, indistinct. 



Iliiidwiiiy : whitish yellow, with a rufous grey patch at anal angle, continued 

 as a faint submarginal band towards costa; inner margin marked with dark scales; 

 fringe yellow ; hindmargin slightly indented beyond cell. 



Underside jiale yellow ; the basal patch and postmedian fascia of forewing 

 dark purplish; cell-spot larger, purplish; hindwing with iiiterruiited ]iur|ilisli 

 submarginal band. 



Head and face yellow; abdomen white; thorax and dorsal area of abdomen 

 rufous grey.
