Agriades coridon var. roystonensis. 
By HE. A. COCKAYNE, D.M., F.E.S. 
Since my paper appeared in 1914, in which I stated that the 
gynandromorphous Agriades coridon from Royston fell under Tutt’s 
ab. inaequalis, there has been some difference of opinion expressed on 
this point. Mr. H. B. Williams supported my view that Tutt’s 
definition covered the Royston form, though he confessed that he did 
not think that Tutt had ever seen one. Mr. Pickett, in the Ent. 
Record, xxvi., p. 275, named the gynandromorphs var. roystonensis, 
and in the January number for the present year defined his meaning 
more clearly and extended it to include not only those specimens. 
showing inequality of size with asymmetry of blue scaling, but also 
those with inequality in the size of the corresponding wings only. Refer- 
ring to Tutt in the same note he says, ‘‘this new form roystonensis was 
quite unknown to him,” and later gives what purports to be Tutt’s 
definition of ab. inaequalis in the following words :—‘‘ Any females 
with the shape of wings normal or equal, but with blue scaling or 
splashes of blue varying on different wings either slightly or a good 
deal.’’ If this had really been Tutt’s own definition it is clear that 
the Royston gynandromorphs would have been ruled out, but a refer- 
ence to the Natural History of the British Butterflies, vol. iv., 1910- 
1914, p. 30, shows that he merely said ‘‘ with blue streaks sometimes 
varying on opposite sides of the same insect.’’ Neither here nor in 
his original description in British Butterflies, 1896, p. 167, is there 
any mention of normality of shape or equality of size. The deserip- 
tions, as Mr. Williams rightly suggested, eover the Royston form. 
Fortunately, I can supply actual proof that Tutt intended it to do so. 
In his Natural Histoay of British Butterflies, vol. iv., p. 6, he describes 
.a teratological specimen: (06) “Right forewing a little shorter, but
