68 THE LEPIDOPTERIST 



New Lcpidoptera from the Jacob Doll 

 Collection 



By Samuel E. Cassino and Wm. Reiff 

 In 1875 Dr. A. S. Packard described in the 

 Memoirs of the Boston Society of Natural His- 

 tory two remarkable cases of peripheral gynandro- 

 morphism of Callosamia promethea. At this time 

 the senior author was studying with Dr. Packard 

 and made the drawings of these monstrosities on lith- 

 ographic stone. The example described in this paper 

 is, we beheve, the only other reported case of gynan- 

 dromorphism in this species, and is from the well- 

 known collection of Mr. Jacob Doll. 



The left antenna is of the normal male, dark- 

 colored, the pectinaions of the under side somewhat 

 shorter than those of the upper side. The right an- 

 tenna is that of a normal female, the pectinatons be- 

 ing of same length, those arising from the joints 

 being black, the others reddish yellow. The front of 

 the head is female. There is a dash of red at the 

 base of the right antenna. The eyes are alike. The 

 right wings are female and show no traces of the 

 male coloring. The proportions are the same as those 

 of the normal female. The right forewing is like the 

 female in shape and differs in this regard from the 

 left upper fore wing, which is the usual male form. 

 The right hind wing is of the normal female shape 

 while the left hind wing is male in form. The upper 

 left wing is male in shape and coloration. The left 

 hind wing is smaller than the right, and the normal 

 male coloring predominates. There are, however, sev- 

 eral streaks of the lighter coloration of the female, 

 and the shape is that of the normal male. The under 

 side of the right wings is female in markings and 

 color. The under side of the left forewing has the 

 dark coloration of the male, though somewhat lighter 

 in shade. The under side of the left hind wing is 

 usually lighter in color than the fore wing., with male 

 markings. The discal spot on the back of the left 

 wing is wanting as in the normal male. The right
