apex a little produced ; costa convex throughout from base to apex. 

 internal angle well rounded. S. c. subdivides midway between the apex 

 and discal nervules, enclosing a triangular space. The three upper 

 median nervules are very approximate, their interspaces narrow, linear. 

 Legs long, slender, with 4 sub-equal, very long acute tibial spurs which 

 are a little shorter in the $ . Abdomen stout, broad as the thorax and 

 four times as long. In % a broad obtuse anal tuft, in 9 its cylindrical 

 tip is suddenly truncate, not narrower than the base of the abdomen. 

 In coloration the single species known is white, with black scales and 

 spots resembling the spotted species of Hijphantria. 



It is closely allied to and yet very distinct from Miltochrista roaea 

 Hiibner of Europe. It nearly equals it in size, but the head is broader 

 between the antennae which are stouter, and the palpi are larger and 

 longer. The costae of the wings are fuller, the outer edges more oblique 

 and consequently the apex more acute than in Miltochrista. The neu- 

 ration is very different from the European genus, since the s. c. ner- 

 vules are shorter, the 3 first median nervules much nearer at their origins 

 and throughout their length, and the 4th m. arises near the middle of 

 the wing, while in Mlltochrhta it arises at the basal third of the wing. 

 In the secondaries the triangular apical interspace is shorter and broader 

 in Clemensia. The legs are longer, slenderer, as are the tibial spurs 

 which are nearly twice the size as those in Miltochrista. 



Clemensia albata n. sp. 



White with ashen and brown scales, dark spots and a black lunate 

 discal spot. Front greyish white. Edges of the prothoracic scales pure 

 white. Thorax and abdomen with greyish scales ; anal tuft white. 



Primaries with six or seven black costal spots. Midway between 

 the base of the wing and the discal spot, is a sinuate abbreviated line 

 proceeding from the 4th costal spot to just below the median nervure. 

 A dot below on the internal nervures. A slight black streak on each 

 side of the 4th m. below the discal spot. Between this median spot 

 and the base of the wing is, in the % , a slightly tawny discoloration. 

 Outer edge of the wing clear white. Marginal row of black dots fine, 

 but very distinct. Fringe clear white. 



Secondaries white but finely dusted with grey scales, gathered into 

 a diffuse very indistinct extra-mesial line. No discal dot.
