individuals were separately exposed to Paratettix males 

 and gave 7, 10 and 14, respectively, and again all were 

 KK females like the female parents and grandparent. 

 One of these females was subsequently mated to a 

 male of the strongly contrasting pattern MM, of her owii 

 genus, and then she produced 12 males and 16 females of 

 the composite pattern KM. 



From left to right, in F^, a female KK was mated to 

 an RR male and gave, in F,, 49JJ:39$$ of the inter- 

 mediate KR pattern. About three weeks after the death 

 of til"' male this K K female was removed to another cage, 

 where she [nocUiced a few offspring, the only one re- 

 conled being a KK female. The next Fo KK female was 

 mated to a TT male of a strongly contrasting pattern. 

 She produced 10 55:4$? oC the hybrid pattern KT, and 

 IT) KK's, all females and without a trace of the TT pat- 

 tern. The following three F^, KK females were placed 

 with Parafrffi.r males and produced 7, 8 and 12 KK 

 females, resj)ectively. The next four F^ KK females 

 were also ex])osed to Paratrffi.r males, and gave 4, 49, 4 

 and 7 offspriiiu\ all like th(^ female parents; while the re-
