1. Chri/sochroa (Melanoxantha) hicolor F., var. nigri- 

 cornis H. Deyr. 



19 (nO. 1250) Febr. 1913 and 1 cT (n°. 3732) July 

 1913, from Sinabang- (Simalur). 

 Both with the white spots on the elytra very large. 



2. Chrysochroa fulminatis F., var. nigra n. var. 

 ecTcT and 999 (n°^ 2841—2847 and 2873—2880) 



April 1913, from Pulu Babi. 

 Of this species three colour-varieties occur, viz. the com- 

 mon yellowish or bluish green one, with the apex of the 

 elytra of a brilliant red; the shining blue one, with the 

 apex of the elytra green, and the black one. Transitions 

 between these forms hardly exist. Kerremans, in his „Mono- 

 graphie des Buprestides", makes no mention of the black 

 variety, which consequently seemed to me to be unknown. 

 On my inquiring, Kerremans however wrote me that it 

 was known to him from Halmaheira. Now it is a well 

 known fact that Kerremans does not like to give names 

 to varieties and though I participate his opinion in the 

 main point, I believe this to be one of the cases where 

 the naming of the variety can be of interest. It seems 

 very possible to me that the different colours are in rela- 

 tion with one or the other particularity of the climate,
