AGRIADES CORIDON VAR. ROYSTONENSIS. 59 
much narrower, than the left; all the interneural spaces well supplied 
with blue scales; the right hindwing also narrower and thinly 
sprinkled with blue seales. The left wings normal and without blue. 
Bevendean, September 7th, 1888, Hodgson Coll.” On p. 80, after 
describing ab. inaequalis, he refers to the same specimen, and according 
to the Editor of the book, the Rev. George Wheeler, includes it as an 
example of this aberration, notwithstanding the inequality in size and 
shape of the corresponding wings. He says, ‘‘ Hodgson notes (tn Witt.) 
that, near Brighton, in 1888, he took a ¢ with blue scaled striz 
between the nervures of the right forewing, which showed no blue 
scaling elsewhere.” I think there can be no doubt that this is the 
teratological female previously described. 
The specimen is still in the Hodgson collection at Cambridge, where 
I examined it microscopically. It bas coarse blue hair scales on the 
small forewing and ordinary blue scales and androconia on both the 
small fore- and hindwings on the right side, thus agreeing in every 
respect with the Royston specimens. This proves that Tutt had seen 
a gynandromorph identical with the Royston form, and called it ab. 
inaequalis, though doubtless both Pickett and Williams are correct in 
assuming that he had not seen one of the Royston specimens. Mr. 
Pickett’s latest definition includes some specimens of ab. inaequalis and 
some which cannot come under this name. 
I do not know whether this discovery makes any difference to the 
validity of var. roystonensis, but suppose that it does not do so.* Iam 
quite sure it is correct to separate the small-winged specimens with 
blue scaling on the small wings from the other forms of ab. inaequalis, 
and also think that Mr. Pickett has taken a step in the right direction 
in grouping together all the females with inequality in the size of the 
corresponding wings. 
I am, however, still doubtful of the wisdom of giving varietal or 
aberrational names to gynandromorphs, though I am aware that Tutt 
and others have done so. Mr. Pickett’s new definition of var. roysto- 
nensis will probably be found to include few specimens which are not 
gynandromorphs, and exclude few, which are. 
This note is written in no unfriendly spirit, but is intended merely 
to settle a point which has been the subject of some controversy. 
Agriades coridon var. roystonensis from the Herts District, 1910. 
By C. P. PICKETT, F.E.S. 
During the end of May we had an air raid “ somewhere in Essex ” 
which greatly upset my nervous system. Being unwell for weeks from 
the after effect, I was ordered a complete rest and quiet, so the middle 
of July saw me off to Royston to catch the “ Blues”’ to cure the blues. 
This holiday soon pulled me round again and I was able to work 
Agriades coridon as I had never worked it before. Here on these Hast 
Anglian heights everything was perfectly quiet (just as nature meant 
it to be) ; you would not know that any war was going on, not even 
the least suggestion of it. My holiday was the longest I have ever had 
* Ags I understand the matter Mr. Pickett comes in as reviser of the inclusive 
name ab. inaequalis and excludes the local race at Royston under the name var. 
roystonensis.--H.J.T.
