new Species of llisteridx'. 57 



This species is rather smaller than cyaiv'penn's, F&hr., an;l 

 differs by the thorax being wholly |niiictati', by tlie sutural 

 stria almost touching the base, the mesosternum is more 

 sharply acuminate and marginate, and the pro3ternal striaj are 

 wider apart especially near and at the base. I have not seen 

 P. coiKjonis, 8eh., but it is elongate and has a di.itinct trans- 

 verse frontal stria.

Chlanii/ilopsis [Byzenia) formicicoluy King, 1869. 



The name of this species appears aa a synonym of C. stria- 

 tella, Westw., in my catalogue of 1905, l-ut I have recently 

 received an example of King's species from Mr. A. M. Lea 

 and I find that it is distinctly different. It differs by being 

 daiker in colour, less quadrate in form (the elytra being 

 relatively longer), by the tiiora.K being acutely angulate at the 

 anterior angles and the ijurface is less opaque and less dis- 

 tinctly granulate, by the elytra having the two elevations 

 behind tlie scutelluui much less oblique and somewhat acutely 

 pointed at their ends. The elevations in striatella are some- 

 what short, distinctly divided in the middle, oblique, and end 

 on each side obtusely. C. inquilina, Lew., differs from both 

 species by being nitid and the thorax is much less transverse 

 and is parallel laterally, the edges in front and at the sides 

 being uniformly and more strongly elevated ; the elytra also 

 have the elevations behind the scutellum perfectly transverse, 

 not oblique, and they are longer and acute at their ends and 

 there is scarcely any discernible median partition. The legs 

 of inquiUna are more robust, a character especially obvious at 

 the bases of the tibiaj, and the median angles of the tibiie are 

 all les3 acute. My specimens of inquiUna and striatella are 

 from Liverpool, N. 8. NVales. 



The species of this genus are probably numerous, and I 

 think that the elevations on the elytra behind the scutellum 

 are likely to afford good specific characters. Mr. Lea has 

 sent me a sketch in outline of a most remarkable new species, 

 lately found in Australia, which will require the founding 

 of a new genus for its reception. The head is entirely con- 

 cealed by its protruding thorax, a structure otherwise only 

 known in the llistcridie in the genus Xiphonotus. 



Saprinus cerarius, n. n. 

 Sapriyius aratus, Lew. Ann. & Mag. Nat. Hist. ser. 8, vol. iv. 

 p. 301 (1909), requires a new name, as Erichson employed 

 ivratus in 1834.
