Mr. G. Lewis on a neio Genus of Coleopfera. 273 



It is less Leperclitioid in sliape than L. suhorhiculata (Miin- 

 ster). I name this species after my friend Prof. Gr. Lind- 

 strom, F.C.G.S., who has so carefully and energetically 

 worked at the pala3ontology of Sweden, and supplied the 

 material for this and other papers on the Ostracoda of that 

 region.

XXXV. — On a neio Genus of Coleoptera (Trogositidae) . 

 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
