Cobalopsis duspecca A. G. Weeks, Jr.^ 

 (Plate XXVI, Figure 2.) 



Habitat: Coroico, Bolivia. Expanse: 1.80 inches. 



Head, palpi, thorax, abdomen and legs, dark blackish brown above, brownish 

 gray beneath. Antennas the same, but somewhat yellowish toward club on 

 under side. Wings above darkish brown, darkening somewhat at basal area. 



On fore wings, are four dots. Two of these are in interspaces next below 

 costa, one-third distance from apex to base. The other two are below, near 

 central portion of wing, and are white lines rather than spots, the first crossing 

 the interspace below top of discoidal space, the second being more prominent 

 and crossing the next lower interspace, a sixteenth inch nearer base than 

 the first. There is a suggestion of a third subcostal dot under the two above 

 mentioned, and in a long series of specimens this would undoubtedly show 

 itself fairly prominently. Under side of fore wing identical with upper surface, 

 except that the color is deader and shades to brownish gray toward hind and 

 inner margins. Under side of hind wing dark brown down to a line drawn 

 from upper angle to centre of inner margin ; outside of this lighter, tending to 

 grayish brown. Just above subcostal nervure, one-quarter inch from base, is 

 a light brownisli spot, and outside of it in same interspace, is another smaller 

 one. There are two other similar spots below each of these slightly nearer 

 hind margin. The grayish brown area above noted has an interspacial line of 

 same color as basal area, not running to inner margin, but showing prominently 

 in centre of wing only, being more in the nature of a series of interspacial 

 lines. The anal angle, on close inspection, is crossed by a few lighter colored 

 transverse lines, very indistinct. 



This is closely allied to C. descritus Mab. Taken in May, 1899.
