prothorax. It has, however, distinctly grown in the last 

 few days ; a week ago, it seemed still of hibernatmg size. 

 It is now 10 mm. in length and very distinctly thicker 



June 8th.— L. eui)hemus looks larger and has got nd ot 

 the black mark on prothorax. Its colour is decidedly 

 paler • the tint is flesh-colour, but is perhaps rather darker 

 than is usually called flesh-colour, a pale faintly brownish 



^' June 10th.— Larva growing ; it is 11 mm. long, 4 wide and 

 3-5 high, rather hexagonal on cross-section, the two sub- 

 dorsal elevations, the lateral flanges, and presumably the 

 prolegs, being about equidistant elevations ; only a very 

 casual glance would regard the larva as cyhndrical; the 

 colour is hardly paler than on 8th. It has none of the 

 original longer hairs of full length, only, indeed, a tew 

 stumps of which two or three are nearly half length ot 

 original hairs ; the finer hairs show under lens as a minute 

 dark dusting. The disturbance of examining the larva, 

 led to its showing some activity in moving about. 



June r2th.— The L. eupJiemus larva is growing and looks 

 well, although the black mark persists near the honey- 

 gland and is accompanied by shght distortion of the seg- 

 ment. The attitude or, rather, position of the larva 

 since it really began to feed is ^uite characteristic and 

 identical with that of the young larva in the autumn, 

 viz. iust outside the heap of ant grubs. Just now, tor 

 instance, it is on the side of the nest head downwards, 

 with the head touching or almost touching the upper 

 examples of the ant grubs piled up in a corner of the nest 

 It has always been very rare and apparently accidental 

 to see a larva of L. eufhemus in any degree amongst the 

 ant grubs. ^ ^ ■ \ 



June 14th.— 13 mm. X 4 mm., larger, paler, less pmk, 

 has a dirty look, chiefly if not entirely due to the minute 

 dark skin points; the black on 7th and after segments 

 still looks very threatening. The larva moves about with 

 some activity (for a Lycaena) always outside brood nest. 

 June 17th.— Larva figured by Mr. E. C. Knight The 

 larva the only one surviving, has a good deal ot black 

 marking and deposit on 7th abdominal segments and on 

 those behind, 8th, 9th, and 10th, with apparently a little 

 deformitv. Kef erring to the analogy of L. alcon and to 

 the structure of this same larva, when entering hibernation 

 in this same instar, I persuaded Mr. Knight to omit the
