106 " Gipiandromorphisiii " (iikI Kindred Problems 



The ground on which these blues occur is a small area and the 

 other blues found there, i.e. Agriades coridon and A. thetis, do not 

 produce g3aiandromorphs. The species is one which does produce 

 gjTiandroniorphs with some frequency, but never in such large numbers 

 in one locality. 



Pantel and Sin^ty have for years bred many generations of the 

 Phasmids, DLnppus morosus and Dixippus sp. unknown, without any 

 loss of fertility or other sign of enfeeblement.

 The left side is male with half uncus and small malformed penis. It shows redupli- 

 cation of the valve and sacculus.

From a large batch of eggs of D. ? sp. amongst many normal females 

 were two males and one halved gynandromorph. The same thing also 

 occurred several times with B. morosus. In 1908 six gynandromorphs, 

 showing the internal and external characters of both sexes, were bi-ed, 

 though the hermaphroditism was not such that both kinds of apparatus 

 were capable of functioning. Most died young, but those which reached
