BYRRHIDvE. — SIMPfcOCARIA. 139 



abbreviated stripes on each, and a double series of white spots in the middle 



of the back, forming a transverse waved striga: body beneath and legs 



dusky-black, sprinkled with rigid cinereous hairs. 

 The colour varies slightly, some examples being of a brighter or ferruginous 



hue. 

 The smallest species of the genus : known by its mouse-like colour, and the 



duplex transverse dorsal striga of white spots on the elytra. 



Rare in England : it has been taken within the metropolitan 

 district; but it appears to be more abundant in Norfolk. " Beach-

Genus CLXXX. — Simplocaria, MarshamMSS. 



Antennas longer than the thorax ; basal joint robust, elongate ; second less robust, 

 subconic ; third slender, elongate, subclavate ; fourth and fifth of equal length, 

 short, subovate; sixth rather short, the remainder forming an elongate 

 gradually incrassated club, the four basal joints of which are transverse, the 

 terminal very large, ovate. Palpi with the terminal joint ovate-acute : head 

 very convex : thorax rounded behind : body globose-ovate, scantily clothed 

 with a fine pubescence : legs rather elongate, slender ; femora slightly com- 

 pressed: tibice a little dilated and bent, simple, without grooves to receive the 

 tarsi, which are somewhat elongate, and pentamerous. 



Simplocaria consists of a group of small species, which may be 

 known from the Byrrhi by the comparative nudity of the body, 

 which is usually very shining, the acuteness of the terminal joint 

 of the palpi, the greater length of the antennae, the slendemess 

 and simplicity of the legs, which are imperfectly contractile, the 

 tibiae not having grooves to receive the tarsi : — the species frequent 

 grassy situations, beneath the bark of trees, &c. 



Sp. 1. concolor. Ovata, nigra, nitida, elytris punctato-striatis. (Long. corp.

By. concolor. Sturm. D. F. ii. \09.pl. xxxv.^/I a. A. 



Ovate, deep shining black, with a faintly bronzed, glossy, very slightly pubes- 

 cent body; elytra rather deeply punctate-striate, the strise reaching to the apex, 

 and the interstices very finely but distinctly punctured ; thorax the same : 

 head impunctate : legs and antennae black. 



Distinguished by its deep black colour, broader form, and nearly glabrous body : 

 — it differs in the latter respect from the other species of the genus, and also 

 by having the peuultimate joint of the tarsi obscurely bilobcd.
