A SINaULAE GENUS OF CAPSIBM. 

 BY DR. O. M. EEUTEE. 



My friend, Dr. E. Bergroth, has sent me for examination a speci- 

 men of a very curious Capsid, found by Mr. J. J. Walker in Tasmania. 

 This insect belongs to a new genus, for which it is necessary to form 

 also a new division. The hemielytra without cuneus and embolium 

 are shaped and punctured nearly as in the Family LygceidcB, with which 

 this insect accords, also by the long first joint of the tarsi, but the 

 membrane is constructed as in Gapsidce. The antennae resemble those 

 of a Cimex or of some AntliocoridcB, and also the general appearance, 

 the broadly oval body, and the ferruginous colour, remind a little of 

 the bed bug. I have named the genus Lygceoscytus, and the species 

 cimicoides. It is probably of old geological age.
