is pure white with a lihiish tint ; tlie outer lialf of forewiiig is tinged with olive- 

 green instead of ochreons, this tint filling np the space between veins 3 and 4 

 and interrupting the sul)raarginal line ; the dark internal edging of the sub- 

 marginal line on inner margin is more prononnced, and is preceded by a pure 

 white blotch ; the inner line, though of the same shape as in abnormipalpis, is 

 lost in the dark olive-fuscous suffusion which extends from base to onter line. 

 The hindwing is uiiich darker, with the ]ialer markings hardly ])crceptible, and 

 the fringe is also dark. Except for the short depressed terminal joint of the 

 palpi, which is that of a true Ischnopteriti, there is very little to distinguish this 

 species from /. abnormipalpis. 



256. Ischnopteris fulminea. 



Chloi-ocli/stafiilminca Dogu., Ann. S. E. Belg. xlv. p. .310. ? (1901). 



After describing this insect from 2 ? ?, Dognin goes on to say that it has a 

 great resemblance to Cliloroclijsta fahjurata Warr. c?, and that an example of this 

 last is in the Berlin Museum (Maassen Collection) marked Sijrtodea phaegopterata. 

 The insect marked Tschnopfrris fulgurata, in the British Museum Collection has 

 never been described, nor, as far as I know, has the example marked phaegopterala, 

 in the Berlin Museum. 



Among a large collection of Geometrids from Peru, lately received, is a pair 

 from the same locality and with the same date, of which the ? agrees with the 

 description ol fulminea, by Dognin, while the S is evidently the same as those 

 navaed f/tlgxrafa and phaegojiterata, but not described. The difference in markings 

 notwithstanding, I must consider them to belong to the same species, which will 

 stand as Ischnopteris fulminea Dogn. 



A detailed description of the i is here ajipcnded for comparison. 

 Fomring : olive-green, striated with blackish ; the costa ])inkish with dark 

 st nations ; the median vein and its branches pale green finely edged with cream- 

 colour, the median vein at base, and a streak on inner margin before middle 

 bright jiink ; a black dash beneath the median at base, edged with pale beneath ; 

 from costa at one-sixth an oblique cream-coloured line, running along median vein 

 above and joining on the discocellular a similar line from middle of costa, the 

 projecting pointed continuation of the two containing a velvety black narrow dash ; 

 an oblique cream-coloured line from costa just before apex emits a short line 

 basewards above vein 6, and is slightly dentate externally ; below the median 

 vein it is continued to inner margin, whore it is semicircularly curved round 

 basewards, meeting the first costal line at a sharp angle on the median ; from 

 the median to inner margin it is edged externally first by a moss-green line and 

 then by a peach-blossom -coloured one ; on each side of tiie median vein in the 

 marginal field is a broad cream-coloured streak, the upjier straight and abbreviated, 

 the lower curving into the tooth at vein 3 ; marginal lunules velvety black, preceded 

 above middle by cream-coloured lunules edged with pinky scales, and below middle 

 by peach-blossom-coloured lunules, this tint also being mixed with the green 

 towards anal angle and forming a pale line across the lower half of the marginal 

 field ; fringe olive-green, i>aler at base, with cream-coloured dashes beyond the 

 principal veins. 



Hrndwing : olive-grey at base, with a dark green curved postmedian line, 

 beyond which the wing becomes jiink-tinged with green speckles, the apex itself
