Lepidoptera from the Falkland Islands. 209 
greyish, becoming yellower on costa: secondaries white, with 
costa and veins buff; a diffused greyish external border ; 
fringes as above: body below sandy buff, greyish here and 
there ; tibial fringes slightly rufous, whitish at tips ; venter 
sericeous. 
E:xpanse of wings 37 millim. 
7. Eupithecia anguligera, sp. n. 
Somewhat intermediate in character between LE. fasctata 
from the Nilgiris and F. stbylla from Chili. Leaden grey, 
slightly tinted here and there with brown: primaries elongate- 
triangular, traversed by about ten wavy blackish lines, but 
extremely variable; the alternate lines, beginning with that 
. nearest the base, blacker, and therefore better defined than the 
others, the fifth and seventh, representing the outlines of the 
central band, black, thicker than the others and acutely angu- 
lated towards costa; the tenth line composed of more or less 
confluent pale-bordered blackish submarginal lunules; a mar- 
ginal series of externally whitish-edged black dashes : secon- 
daries with hardly a trace of marking from the median vein 
upwards; a triangular black patch at base below the cell, 
followed by six blackish zigzag lines, of which the first, 
third, and fifth are best defined and quite black upon the 
veins; marginal black dashes as on the primaries: thorax 
pale leaden grey, with darker transverse bands; abdomen 
much darker, with almost confluent blackish bands in the 
type, but extremely variable in depth of colour in a series. 
Under surface sericeous leaden grey; all the wings with 
black or blackish discocellular stigma, followed by two 
parallel blackish lines ; the secondaries with traces of a third 
(subbasal) line; black marginal dashes as above. 
Expanse of wings 19 millim. 
A series of twenty-one examples, most of them more or 
less worn. 
In some specimens the markings are very indistinct, in 
others the two black lines of the central band alone remain, 
with a well-defined discocellular stigma (which, in the type 
above described, is only shown on the under surface) ; in 
others again the outer line of the central band is only marked 
with black on the veins. In all these specimens, however, 
such markings as exist are similar in outline and similarly 
placed, so that it is evident that they represent only one 
variable species.
