Mr. G. Lewis on a new Genus of Coleoptera, 273 
It is less Leperditioid in shape than L. suborbiculata (Miin- 
ster). I name this species after my friend Prof. G. Lind- 
strém, F.C.G.S., who has so carefully and energetically 
worked at the paleontology of Sweden, and supplied the 
material for this and other papers on the Ostracoda of that 
region.

XXXV.—On a new Genus of Coleoptera (Trogositide). 
By G. Lewis, F.L.S. 
THE species here described belongs to a genus which I 
believe is widely spread in its distribution but not yet charac- 
terized. ‘There are species in the British Museum from the 
islands of Tropical Asia, and Mr. Pascoe has one or more from 
Tropical America. I have not examined these last insects
