104 POLYOMMATUS (lYC^NA) ALSUS. 



It was neither suspended by the tail nor had it any- 

 silken cincture, and it might very well be passed over 

 as a stony particle on the chalky soil of its habitat on 

 Portsdown Hill. 



The colour of the pupa is dirty whitish-grey 

 approaching to drab, palest on the back of the abdo- 

 men, greyish on the head and thorax, both of which 

 are marked with a black dorsal stripe, which is a little 

 interrupted ; on either side is a subdorsal row of short 

 slanting black dashes. The pale ground colour is 

 sprinkled with some very minute black specks. The 

 wing-nervures are well denned by the spaces between 

 them being filled up with dark grey. The head, thorax, 

 and abdomen are hairy with bristly whitish hairs, of 

 which there are none on the wing-, leg-, and antenna- 

 cases. 



The butterfly made its appearance June 24th, 1873, 

 at 10 o'clock in the morning. (W. B., Note-Book 

 II, 12.) 



The whole year's history of this species comes to this : 



Egg laid about the middle of June. 



Larva hatched within a week ; full fed and fixed 

 motionless about the end of July. So continuing for 

 ten months till the beginning of next June. 



Pupa state then lasting for some two or three weeks, 

 and the 



Imago living but a short time to perpetuate the 

 species. 



The long continuance in the larva state after being 

 full fed seems very remarkable. (J. H., 14, 6, 73 ; 

 E.M.M. X, 43.)
