the third, fourth and fifth are bowed between the veins, giving a waved 

 effect, forming sharp apices on the veins ; the sixth is broader and 

 terminates at the apex; the seventh joins the sixth just before it 

 reaches the apex. On the costal margin at one quarter of the distance 

 from base to apex, a line 2 mm. in length extends obliquely towards 

 the inner margin, then runs basally at right angles for 3 mm.; distally 

 of this line and 1 mm. from it there runs another parallel to it; from 

 these lines basally and limited by the first of the postmedian trans- 

 verse lines and the inner margin is a pale ochraceous salmon-colored 

 area. 



Secondaries : Bister color at base, shading into Fronts brown to- 

 wards distal margin. A row r of eight yellow ochre spots, placed one 

 between each two veins, extends from anal angle nearly reaching the 

 costa. 



Underside. Primaries: Basal half of wing Dresden brown. A warm 

 buff patch reaching from inner margin to costa which is of the same 

 color ; outside of this is a clay-colored patch which starts at anal 

 angle, widening at center, then narrowing again as it reaches the apex. 

 There is a reddish brown point on each vein in the warm buff patch. 



Secondaries : Warm buff. A clay-colored stripe extends from near 

 anal angle along inner margin, widening as it reaches the apex. A 

 row of brown points extends from costa to near anal angle, one on 

 each vein ; interior and parallel to these points are two reddish brown 

 lines, the one nearer the base of wing being more pronounced. 



Extent of one wing, 29 mm. 



Type: One male, Guaiitanamo, Cuba, 20th June, 1917, in 

 the collection of The Academy of Natural Sciences of Phila- 

 delphia. 



The above species is close to X. fosteri R. & J., but differs 

 from it, above, in having the stigma very obscure while in 

 fosteri it is very prominent. The solid brown area between 

 the two basal transverse lines of fosteri extending from the 

 inner margin about 4 mm., and standing out in sharp contrast 

 with the rest of the forewing, is entirely lacking in clarki. The 

 row of eight yellow ochre spots of the secondaries of clarki is 

 replaced by a continuous band in fosteri.
