Species and Forms of Geometv'idde, 311 



Fore wing moderately broad, terraen with the curvature 

 in middle well appreciable; all tlie subcostals stalked beyond 

 the areole (typej or SC^ just separate (paratype); black, with 

 a rather large (circ. 5 mm. long) white subbasal patcli 

 occupying a large part of cell (but not crossing cell-fold in 

 distal part) and the area behind, bounded posteriorly by 

 SM^, vein M and fold remaining more or less black ; a 

 round white spot between R^ and M^ near their origin. 



Hlad wing white, with a rather broad (circ. 4 mm.) black 

 distal border, which is somevvhat sinuous-edged proxim illy 

 and is costally cut off rather abruptly opposite the bifurca- 

 tion of SC2 and Ri. 



Fore wing beneath with the white area extended behind, 

 its distal edge running obliquely (though not quite regularly) 

 from base of M^ to near tornus ; an ill-defined black area 

 beyond, narrow at radials, then broadening so as to embrace 

 the outer white spot, which is as above ; the rest brown-grey, 

 with the veins blackened. Hind wing white^ with the border 

 as above, but brown-grey, the veins blackened, a small black 

 mark from costa to R^ at its commencement ; a minute 

 cell-dot at anterior end of DC'^. 



E. Peru : Oxapampa, 6400 ft., type in coll. L.B. Prout ; 

 Chanchamayo, paratype in coll. Brit. Mus. 



Rather noteworthy for the Devarodes-\\k.Q underside. 



8. Erateina haenschi, sp. n. 



c^ . — 43 mm. 



Pace black, a very pale yellowish band at side. Vertex 

 black. Postorbital rim and a mark on collar pale yellow. 

 Palpus black, narrowly whitish beneath. Antenna with 

 fascicles of slender cilia about as long as diameter of shaft. 

 Thorax above black, marked with whitish ; beneath pre- 

 dominantly pale. Abdomen above blackish, with narrow 

 pale edging to the segments, anal end with large white- 

 yellow spots ; beneath buff or reddish, with blackish bands. 

 Fore coxa, fore femur, and middle and hind legs predomi- 

 nantly pale. 



Fore iving rather elongate, termen (except near apex) 

 straight, strongly oblique ; brown-black, proximally (to 

 about 6 mm. at costa, 8 at hind margin) paler and more 

 olivaceous ; a narrow yellowish- white band from close to mid- 

 costa towards tornus, mostly 2 mm. wide but tapering behind 

 M^, slightly incurved, ending in a point before SAP; fringe 

 mixed with white distally. 



Hind iving strongly elongate and produced into a long- 

 tail (length of wing from base to end of R^ 17 mm., from
