caused by the more or less density of the white irrorations, in one speci- 

 men the basal dark area can hardly be defined. 



Eucosma biii?ieana, sp. nov. — Expanse, (^ , 24 to 30 mm.; $ , 32 mm. 

 Fore wing pale clayish-ochre, with two horizontal black lines, one from 

 base to middle, and one above it from middle to apex, the latter divided 

 and more or less diffused on its outer half. 



Head rough, dull brown in front, shading into ochreish-brown on lop. 

 Palpi flattened, ovate, scales neither compressed nor loosely laid, apical 

 joint exposed above, but hidden below by projecting tuft from second 

 joint; colour pale ochreish, darker on outer sides and below, apex brown. 

 Antennse ochreish, lightly ciliated in both $ and $ . Thorax whitish- 

 ochreous, shading into dark brownish-ochreous anteriorly. Abdomen and 

 legs cinereous, tarsi and tibiae marked and dotted with dark brown. 



Fore wing pale, terracotta or clayish-ochre ; palest along dorsal 

 margin, and overlaid with a deeper ochreous shade along costa and outer 

 third. A narrow black line through middle of wing from just beyond 

 base, nearly to end of cell, where it diminishes to a hair streak and follows 

 vein ii nearly to angle. Above the outer end of the thickened part of this 

 line, at two-thirds length of cell, another wide line begins, and continues 

 to end of cell, where a narrow spur from its up edge continues in termen 

 just below apex ; the inner end of this line is somewhat clavate, beyond 

 its outer end, below the apical spur, is a cloud of whitish, dark brown and 

 ochreous scales, between veins v and vii, and over the latter line is a 

 second spur of black scales, but much broken. The costal fold is nearly 

 half the length of wing, closely appressed at base, but rolled over at its 

 outer end ; colour, ground colour, but of a more sombre hue ; costa 

 beyond fold pale ochreous, with five evenly-spaced black dots, below 

 these are five or six other black dots, not evenly spaced. On the dorsal 

 margin are about the same number of black dots, closer together about 

 the middle. A row of similar dots along the termen, and a iQ.w others 

 scattered over the wing, several in the ocellic space, one below outer end 

 of second horizontal line, and a faint line below and paralleling the inner 

 half of the inner line. Cilia grayish-fuscous, paler basally and mottled 

 with darker fuscous scales. Hind wing above and below smoky-ochreous, 

 cilia paler. Under side fore wing smoky-fuscous, paler along costa, where 

 the dark costal dots are repeated. Cilia paler. The above description is 

 from an average $ , in other specimens the intensity of the dark lines and 

 dots are less or greater. In one A specimen the dark markings are nearly 

 obsolete, leaving only a faint basal and faint outer line, no dots at all. while
