HO P. W. WHITING AND ANNA R. WHITING. 



Head was male, left antenna had twenty-two joints, right 

 antenna was broken but there remained thirteen joints. Ab- 

 domen was entirely female, ovaries and poison apparatus were 

 normal and there were no sperm in the seminal receptacle. 



Tests extending over five days showed no reaction to cater- 

 pillars, definite negative reaction to males attempting to mate, 

 no mating reaction toward males, but aggressive response to 

 females, flipping, mounting, etc. 



The formula for the method of origin would be similar to 

 that for freak 32. 



Freak 5. An orange female of the third generation from the 

 orange mutant male of L. stock was crossed with a black male 

 of the fourth generation of Mifflintown (M.) stock. There were 

 produced 13 orange males, 15 black females, and a black-eyed 

 gynandromorph, freak 5, found in vial a (July 22, 1920). 



The head of this gynandromorph was female, fifteen joints in 

 each antenna (Fig. 17). Wings were normal. The abdomen 

 was female in the first three segments and entire right side. 

 The left posterior quarter was distinctly male. There was a 

 full set of male external genitalia including penis, and first and 

 second pairs of claspers. A portion of the sting, much mal- 

 formed, and the right sensory gonapophysis were present (Figs. 

 18-21). Internal organs were much confused. The digestive 

 tract appeared normal and ran dorsal to the poison apparatus 

 which was slightly toward the right. Poison duct led from the 

 malformed sac to the base of the sting. Poison glands were 

 approximately normal. Seminal receptacle was normally located 

 and devoid of sperm. Nerve ganglia were well developed. 

 Vasa deferentia ended blindly. Testes were far out of position, 

 lying dorsally in the anterior part of the abdomen. They were 

 large and well-formed with cysts of spermatocytes (?) but no 

 sperm. Ovaries were altogether absent. 



Reactions of freak 5 seemed entirely female. It was in- 

 different to females, seemed willing to mate with males and 

 then turned abdomen down to avoid them. It inspected cater- 

 pillars with its antennae and tried to sting them. It also stuck 

 its abdomen under a paralyzed caterpillar as if attempting to 

 oviposit. The tests were all made in one day after which the 

 specimen was killed.
