 stant on Simalur and on its satellite-islets.

 Andalas (Highl. of Pad.), Muara Sako (Kurintji) — 3, 5 and 6/1914, 

 3 and 9/1915. 



— pseudocostalis v. E. — 2 99 — Sinabang (Simalur), Pulu Babi — 

 3/1913, 5/1915. It is my positive opinion, proceeded from an anatomical 

 research, that gaura and daos Boisd. belong to the same species (see 

 p.p. 218 and 319, vol. XXXVI Notes Leyd. Mus.). Pseudocostalis, figured 

 on plate VII, is clearly intermediate between gaura and daos. Mr. Piepers 

 has written in his work on the Erycinidae and Lycaenidae of Java 

 (p. XLV) that he does not believe, that gaura Horsf. and daos Bsd. 

 belong to the same species, because „the systematic conception of species 

 does not depend upon the absence or presence of a difference in a parti- 

 cular organ". All right! But Mr. Piepers has not well read my publi- 

 cation on this subject. In his systematic work Mr. Piepers seems to set 

 a high value on the pattern! I should like to show Mr. Piepers a series 

 of gaura-, pseudocostalis- and daos-r&ces and he will be the first to call 

 them „evolutionforms" of one species. The biological, morphological and 

 anatomical data indicate one species!
