BRITISH BUTTERFLIES. 



Page 320, lines 37-38. — The egg of Thestor ballus here referred to is stated by Sich 

 (Ent. Rec, xviii., p. 239) to be most probably that of Callophrys rubi. 



Page 355, line 10. — For " ab. hilbneri, n.ab.," read " ab. hiibneri, Obth., Bull. 

 Soc. Ent. France, 1905, pp. 55-56." 



Page 369, line, 18. — For " toward the base," read " toward the base of hindwing." 



Page 392, line 3. — Perhaps " ragwort" is not so probable a mistake after all, for 

 Harrison writes (in litt., August 24th, 1906) that, on the sandhills at 

 Burntisland, Fife, he found a colony of the larvae of this species feeding on 

 Solidago virgaurea.
