AGRIADES CORIDON VAR. ROYSTONENSIS. 61 
able to get more by working these sheltered corners. I did not 
come across any roystonenstis paired, nor did I observe any attempts at 
pairing. This also applies during the past five years. The females 
were fully out by mid-August, and it was a sight to see them at rest. 
I dropped on a spot near Royston (a little farther afield), called ‘‘ Ther- 
field,” where coridon were in countless thousands, indeed in all my ex- 
perience I have never seen the females in such swarms, in the last week 
in August they simply had it all to themselves (for the males were all 
but over), they were flying in droves, it was a perfect treasure hunt for 
aberrations. By the beginning of September the females were quite 
worn out, and a few cold nights placed coridon out of reach for another 
season. 
The following are some of my choicest captures :— 
Mauss. 
Uppersides.—F rom whitish-blue to sky blue. 
Many ab. sufusa and ab. minor. 
Many approaching ab. fowlert. (Mr. Newman took a perfect 
ab. fowleri.) 
Many males with slight red lunules over the black spots in the 
hindwings as in the females (ab. swasa). 
Undersides.—Several perfect ab. obsoleta (all four wings minus 
spots). 
Several ab. obsoleta (with lower wings minus spots). 
Several ab. striata. 
Two with ground colour of a darkish grey (easily passable as 
female). 
FEMALES. 
Uppersides.—Several approaching ab. syngrapha, with blue on all 
four wings, the upper wings with blue almost covering the 
whole area. 
Several ab. semi-syngrapha, with prominent red lunules in 
margin of hindwings. 
Many white rayed; this is a very pretty new form, the spaces 
between the nervures, from the edge of the forewings to the 
centre, contains whitish rayed markings. 
Two of a lovely golden-brown or light khaki shade. - (Another 
was also taken by Mr. Newman.) 
Several with these golden patches on various parts of the 
wings. 
Two with the red marginal spots joined up, forming a con- 
tinuous red band. 
Two perfectly black with no marginal markings. (This form 
is far rarer than one would expect.) 
Undersides.—Two perfect ab. obsoleta (all four wings spotless). 
Several ab. obsoleta (lower wings spotless). 
Several ab. striata, lone black dashes. 
Several with ground colour of a blackish-grey. 
Several with ground colour very light (equal to male). 
Fourteen ab. inaequalis (aormal wings all gynandromorphs). 
Five splashed with blue on right side upper wing. 
One splashed with blue on right side upper and lower wing. 
One splashed with blue on right side lower wing.
