is thickened opposite to and projeciing into the lunules of the t. p. line. 

 Terminal space light yellowish brown, very even in colour. Black lunular 

 lines at base of fringes, which are defective in thespecimen before me, but 

 appear to be concolorous with terminal space. Hind wings fuscous, 

 somewhat darker externally to an obscure mesial line. Discal dot present, 

 though not pronounced. Abdomen yellowish fuscous. Beneath yellowish 

 fuscous, with the common median band and discal dots not prominent on 

 hind wing. Legs, thorax and abdomen somewhat darker fuscous.

Oficocnemis Polingii, n. sp. — Expanse : 28 mm. 



Head, collar and primaries from base to t. p. line, as well as the ter- 

 minal space, of a light brown colour. Thorax, orbicular and subterminal 

 space lighter in colour, contrasting, the first two being of a yellowish- 

 white or gray colour, while the last, showing less of the yellow tinge, is of 

 a more bluish-gray colour. The head and palpi are of the same general 

 buff ground colour, with an admixture of black and white. There are 

 two black bands across the head between antennae, and three across the 

 collar, v/hich is tipped with whitish. The thorax and patagia are clothed 

 with a mixture of buff, black and white hairs and scales, the white pre- 

 dominating so as to give a yellowish-gray effect as a whole. There is a 

 quite well marked posterior thoracic tuft. Abdomen of a quite uniform 

 buff colour ; along the dorsum, especially of the basal segments, a few 

 black hairs can be seen grouped together, and at the base cf the anal tufts 

 they form a transverse band, which is quite distinct under a lens. Thorax 

 and abdomen beneath a shade lighter than above, the former thickly 

 coated with hair. Legs checkered buff and black. Anterior tibiae with 

 stout spur. Primaries above with the ordinary lines and spots distinctly 

 and neatly marked. Basal half line single, black and well defined, joined 

 at lower end by spur from t. a. line along median vein. The t. a. line is 

 somewhat thickened at its origin, which is almost directly above the inner 

 edge of the orbicular ; from this point its course is downward and inward 

 to the median vein, thence downward and outward, making two outwardly 

 convex scallops before reaching inner margin. The line is black, distinct 

 and neatly defined ; it is accompanied on its inner side by a brownish 

 line, more diffuse and not so neatly defined. The accompanying line 

 follows the spur connecting the basal and t. a. lines on both upper and 

 lower sides. On the upper side it joins a similar line on the outer side of
