LEPIDOPTERA, FAM. PIERIDAE.

7. Gandaca harina Horsf. cf. No. 4309. 



Hab. Sinabang (Simalur), 



Gandaca harina Horsf. nov. var. gilva. 5 cf. Nos 4310 

 —4314. 



Hab. Pulu Babi. 



Exp. alar. 40 mM. The habitus is that of harina'^ the 

 colour is yellow, without any pattern. On the apex are 

 some brown squamae, being the last remnants of the charac- 

 teristic apical and marginal black spot. 



It is possible, that this form is an example of season 

 dimorphism, but I do not think it in this matter. The islet 

 Pulu Babi is totally overgrown with a very dense forest; 

 according to the letters of Mr. Jacobson it was very rainy 

 also in the east monsoon ; the butterfly is captured in April. 

 The differences of climate will be not important on these 

 islands. Fruhstorfer knows a subspecies of Lombok, austro- 

 sundana^ in which the black margin is absent in the east 

 monsoon (Seitz, Faun. Indo-austr. p. 173).

Copulatory organ of the cf of Gandaca harina Horsf., nov. var. gilva. 



Of one of the five males I have prepared the copulatory- 

 apparatus and also that of the real harina of Java. In 

 consequence of these researches I may write with certainty 

 that gilva is a variety. The subspecies samanga Fruhst., 

 mindanmnsis Moore, assamica Moore, elis Fruhst. and aigina 

 Fruhst. are, I think, also varieties of harina.
