226 THE ENTOMOLOGIST S RECORD. 
II. Primary Somatic HermMarsRoDITEs. 
Sex gland or glands of one sex only, but parts of the secondary sexual 
apparatus, internal or external, of both sexes present. 
a. Male type, with one testis or two testes. 
b. Female type, with one ovary or two ovaries. 
Ill. Sxrconpary Somatic HerRMAPHRODITES. 
Sex gland or glands of one sex only; secondary sexual apparatus 
of one sex only, that corresponding to the sex gland ,present. 
Secondary sexual characters of both sexes present in antenne, 
wings, or other parts of body. 
a. Male type, with one or two testes. 
b. Female type with one or two ovaries. 
Gynandromorphism associated with Heterochroim. 
Heterochroism is the term introduced by the author to distinguish 
insects which, ‘in addition to being gynandromorphous, exhibit the 
colour and pattern of the type form in all the parts which are of the 
one sex, and those of some varietal or aberrational form in all the parts 
which are of the other sex.” ... ‘These strange gynandromorphs 
not only exist in the halved and nearly halved forms, but also in the 
crossed and coarse mosaic forms.” This segregation of colours of pat- 
terns is “ quite unconnected with sex.” 
Reference is made to the lists of palaearctic gynandromorphs made 
by Schultz, and numerous additional instances are described. 
Larve which showed Heterochroism and produced Gynandromorphous 
Imagines. 
Insects showing segregation of somatic characters (Heterochroism) but 
no seyregation of sexual characters (Gynandromorphisin). 
Gynandromorphs partly of male type colour, and partly of aberrational 
colour limited to the female sea. 
Under each of these headings a considerable number of examples» 
many newly described, are given in detail. 
HEREDITARY AND FaminiaL Nature oF GYNANDROMORPHISM. 
Instances are given from the experience of Harrison and Main, C. 
W. Simmons, E. B. Haynes, H. B. Williams, H. Donisthorpe, ete. 
Hereditary Gynandromorphism probably of Indirect descent. 
In a series of admirable diagrams the author gives the results of his 
microscopical examination of eight gynandromorphous Amorpha popult 
bred by L. W. Newman. 
Hereditary Gynandromorphisin probably of Direct descent. 
This section contains details of the examination of a large number 
of Agriades coridon from the now famous Hertfordshire locality, as well 
as references and criticism regarding many other cases which fall in 
this class. 
Hysrip GYNANDROMORPHS. 
Gynandromorphism is far commoner among hybrids than amongst 
pure races of Lepidoptera. 
Here are considered the Gynandromorphs of the hybrids Amorpha
