CREMASTUS GHACILIPES Cushman 



Three rearings of this species from the type-host {Dicymolomia 

 julianalis Walker) have added three females and five males (the latter 

 sex undescribed) to the national collection. These are as follows: 

 1 of each sex reared by E. Daecke at Kockville, Pa., on June 22, 

 1915 ; 1 female and 4 males reared September 22, 1909, at Collins, Pa. ; 

 and 1 female reared March 14, 1924, at Smith's Point, Tex. There is 

 also an apparently indistinguishable female reared from the Oriental 

 Peach Moth {Laspeyresia violesta Busck) at New Brunswick, N. J., 

 by Alvah Petersen. 



The females show a variation in color from that of the type and 

 a phase in which the red color of the head is replaced by yellow and 

 the thorax and abdomen are much more extensively black. 



The male shows the same sort of variation in color with frequently 

 the entire lateral face of pronotum, the notauli and more or less of 

 the mesopleurum yellow ; also the legs are paler, especially basally. 



In my key the male runs to couplet 3, where it agrees with neither 

 alternate entirely. The diameter of the lateral ocellus is about equal
