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. 



Expanse of wings 37 milliin. 



7. Eupithecia anguh'gera^ sp. n. 



Somewhat intermediate in character between E. fasciata 

 from the Nilgiris and E. sihylla 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 lunulas ; 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.
