brown lines. Thorax and abdomen whitish, sometimes tinged with yellow. 

 Abdomen with a faint dorsal line, sometimes marked by brown dots in posterior 

 margins of segments. 



Primaries brownish white, the veins in both lobes more or less definitely 

 tipped with brownish black. There is sometimes a faint brown spot contiguous 

 to base of cleft and a dark basal dash below the cell. The wing is slightly 

 darker toward the costa, and there is usually an evident shade on the costa 

 of the first lobe, especially above base of cleft. Fringes concolorous at base, 

 grayish at tips. Secondaries approximately concolorous, fringes the same. Ex- 

 panse 25-28 mm. 



Distribution : Described from Kentucky. North Carolina to Nova 

 Scotia, west to Colo. May to July. 



The type of lacteodactylus is now in the Cambridge Museum. It 

 is a large specimen and well worn, but is sufficiently well preserved 

 to establish its identity satisfactorily. The species is rather closely 

 related to kellicottii but dilTers in the absence of a well marked spot 

 at the base of the cleft on the primaries and in other slight features, as 

 well as in the form of the genitalia. There is no reason for confusing 

 it with siibochraceus for that species has no marginal or discal spots. 



The life history is unknown.
