NEW BRITISH SPECIES, ETC., IN 1864. 51 



into Mr. Janson's possession. Mr. Brewer has since taken 

 a few more specimens, which are now in the collections of 

 Mr. Waterhouse, Dr. Power, and myself. 



As Mr. Janson (loc. cit.) remarks, the extraordinary re- 

 semblance which this species bears to the members of the 

 genus GyropliCBna, has misled more than one author as to its 

 true affinities. It may be known from any Gyrop]i(Pna by 

 its labium being bifid, instead of entire ; its labial palpi 

 having three joints instead of two ; and by the basal joint of 

 its hinder tarsi not being elongate. 



It is short, rotundate, black, shining, with the legs and 

 base of the antennce reddish. The thorax is short and con- 

 vex, and the sides of the abdomen are rounded. 



There appears to be a brown variety, in which only the 

 head and apex of abdomen are black.

Of the same narrow linear form as O. pusillima, which it 

 scarcely equals in size, and from which it may be known by 

 its brown elytra and the bright yellow terminal segments of 

 its abdomen. The three apical joints of the antennse are 

 broad. It differs from O. atomaria, amongst other things, 

 in having entirely pale legs. 



Taken in a refuse heap on Shirley Common, near Croydon, 

 during last September, by Mr. D. Sharp and Mr. E. Shep- 

 herd.
