anterior (upper) angle of ilils projecting arm, E,^"^ from a 

 point at its posterior (lower) angle. The large hair-tuft on 

 underside of fore wing is ochreous grej, not raven-black as 

 in peregrina. 



Eupithecia albtsecta, sp. n. 



(^ . 24 mm. — Face whitish ochreous, vertex white ; palpus 

 long, dark above. Patagia and tegulse marked with white. 

 Abdomen ochreous, the second segment with a dark brown- 

 black belt. Fore wing dull chocolate-brown ; costa nearly 

 to apex broadly cream-coloured, the extreme edge slightly 

 fuscous tinged; median vein broadly whitish; an oblique 

 double whitish line from middle of inner margin, angled 

 about R^ and retracted to costal streak ; traces (especially at 

 costa) of an interrupted white subterminal line ; fringe 

 nearly concolorous with wing. Hind wing rather paler, with 

 the double whitish line straight and antemedian. Underside 

 paler, with weak transverse lines (the postmedian diffuse) and 

 dark cell-spot, that on fore wing the larger.

Except for the totally different hind wing above, this 

 species might be taken for a form of E. pallidicosta, Warr. 

 Nov. Zool. xi. p. 633, which is certainly variable. 



Subfam. Geometrinm. 



Leuciris master iotts, sp. n. 



(J. 26 mm." — Apparently indistinguishable from large, 

 unmarked examples of L. fimhriaria, Cram., except in the 

 antennal ciliation, which is very much shorter, the longer 

 (outer) series scarcely twice as long as width of shaft. 



Porto Rico. Type in coll. L. B. Prout. 



In erecting L. heneciHata (Ann.& Mag. Nat. Hist. (8) vi. 

 p. 437) I unfortunately compared its male antennal ciliation 

 with that of the present species instead of with Xwxq Jimbriaria. 

 I find the last-named agrees with beneciliata, so that it 

 remains just possible (though not probable) that beneciliata 

 is merely a local race of Cramer's species, distinguished by 

 the much more highly developed transverse markings and 

 narrower terminal spots (the latter distinction not noted in 

 the original description). In any case, mysteriotis is a 

 structurally valid species.
