in ? its cylindrical tip is suddenly truncate, not narrower than the

This genus is closely allied to, and yet very distinct from Millochrista 

 of Europe. The head is broader between the antennae which are 

 stouter, and the palpi are larger and longer. The costa of the wings 

 are fuller, the outer edges more oblique, and consequently the apex 

 more acute than in Millochrista. The neuration is very distinct from 

 the European genus, since the subcostal nervules are shorter, the three 

 first median nervules much nearer at their origins and throughout 

 their length, and the fourth median arises near the middle of the wing, 

 while in Millochrisla 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 of those in Millochrisla. "

' ' White with ashen and brown scales, dark spots and a black lun- 

 ate discal spot. Front grayish white. Edges of the prothoracic 

 scales pure white. Thorax and abdomen with grayish scales ; anal 

 tuft white. 



" Primaries with six or seven black costal spots. Midway between 

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

 proceeding from the fourth costal spot to just below the median nerv- 

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

 each side of the fourth median below the discal spot. Between this 

 median spot and the base of the wing, in the 3 , a slighdy tawny dis- 

 coloration. 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 gray scales, gathered into 

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



" ? is clearer white, the extra basal line is much less distinct than 

 in the 5 , consisting of a linear spot connected with the costal one.
