Hah. Africa. 



The single specimen in my collection was formerly in that of 

 Major V. Quedenfeldt and has uo particular locality indicated ; 

 the species differs from all its allies in the coloration.

 finely punctured, the margins very narrowly black.

Note. 



Nerissidius, Weise. — A Eumolpid genus described by Weise iu 

 the Deutsche entom. Zeitsch. 1895, and allied to Kerissus, is com- 

 pared with this genus by the author, but the latter has evidently 

 overlooked Baly's genus Cheiridea (Journ. Linn. Soc. 1877), which 

 has the sides of the thorax likewise serrate, and with which Weise's 

 genus may be identical ; but no mention is made in regard to the 

 shape of the thoracic margin of the episternum, which at present 

 forms the chief character of distinction in the two principal groups 

 of Eumolpinci'.

 larly and closely impressed with small and still smaller punctures.
