Explanation of Plate IX. 



(To be bound facing Plate IX.) 



Structural details of Pupa of Agriades coridon. 



Fig. 1 (right-hand side). — Ventral aspect of abdominal segments 5, 6, 7, and 8. 

 The mid-venter is free from hairs, and the skin -sculpture is reduced to fine 

 longitudinal wrinklings. [Abdominal segments 9 and 10 show no trace of 

 cremastral hooks, either in the portion photographed or elsewhere] x 40. 



Fig. 2 (left-hand side). — Spiracular region of the 2nd abdominal segment. This 

 should be compared with the corresponding plate of A. thetis (preceding 

 volume, pi. xlvii), much more magnified than this, but bringing out well 

 the different size and character of the hairs, etc. x 75.
