This species though widely distributed has uot beeu recorded any- 

 where as common. Two Texau specimens in the Museum collection are 

 very much paler in color than the generality of specimens, and are en- 

 tirely intermediate between suffasa and clymene in this respect. The 

 entire habitus, however, and more particularly the two spots on pro- 

 thorax, leave no doubt where the specimens are referable. It would be 

 interesting to know whether they are albinos, or whether suffusa and 

 clymene sometimes mate. The maculation of primaries is precisely iden- 

 tical in both species. 



Walker mentions four varieties: 



a Hind wings with three submarginal spots and a marginal streak. 



,3 Hind wings with two submarginal spots. 



/ Hind wings with one submarginal spot. 



6 Hind wings unspotted. 



I have never seen the first and second of these varieties. 



In this species the side pieces of the $ have both upper and lower 

 angles produced and somewhat acute, the upper portion, however, much 

 longer than the lower. 



I cannot find that the larva has been described. 



On plate xiv, figs. 2, and 7-11, are shown the only variations known 

 to me. 



C. lactata, sp. nov. 



Head and collar yellow ; palpi black tipped ; anteunte black. Thorax 

 white, immaculate. Abdomen yellow, immaculate. Beneath thorax 

 and legs yellow. Anterior tibia and tarsi and middle, tarsi blackish 

 outwardly. Primaries a very pale creamy white, immaculate. Second- 

 aries yellow, immaculate. Beneath yellow, immaculate. 



Expands 2.25 inches =55-50'""'. 



Habitat. — Texas. 



Two female specimens are in the Museum collection (Coll. O. IMeskc)^ 

 others are undoubtedly scattered in collections as albino or aberratic 

 forms of clymene, which indeed it may possibly be. I prefer to consider 

 it distinct for the present, because I have never seen anything like an 

 intergrading series between the two, and the form will always hold 

 varietal rank anyway, even should it prove specifically identical with 

 clymene^ which I scarcely believe.
