96 MANDIBULATA. — COLEOPTERA. 



drangular, the edges distinctly margined, with the angles obtuse, and 

 the base somewhat remote from that of the elytra. 



Sp. 1. Juglandis. Fit sea, opaca, scabra, antennis pedibus maculaque humerali 

 rvfo-testaceis, elytris crenato-striatis, seriatim hispidis. (Long. corp. 2 lin.) 

 Ly. Juglandis. Fabricius. — Ly. Juglandis. Steph. Catal. 90. No. 966. 



Obscure dull fuscous, scabrous: head nigro-fuscous, finely punctured; mouth 

 and labrum testaceous : eyes black : thorax slightly convex, obsoletely punctate, 

 clothed with depressed griseous hairs, fuscous with the anterior margin tes- 

 taceous : elytra somewhat remote from the thorax and rather broader at the 

 base, dilute fuscous, with an indistinct, indeterminate obscure testaceous spot at 

 the base; the disc rather deeply crenate-striated, with alternate rows of some- 

 what erect, short, pale cinereous hairs : legs and antennae ferruginous. 



Found within the metropolitan district. 



Genus CLVI. — Cerylon, Latreille. 



Antennas shorter than the thorax, rather stout, the basal joint rather large; the 

 second somewhat smaller, both obconic ; the seven following very short, 

 granular, slightly increasing in size; the tenth very large, globose, with a slight 

 acuminated appendage at the apex. Palpi filiform, unequal : maxillary twice 

 as long as the labial, with the last joint elongate, rather attenuated towards 

 the apex, truncate : mandibles arcuated : head broad, exserted : eyes globose, 

 prominent : thorax quadrate : body oblong-ovate : legs rather short ; femora 

 slightly clavate ; tibia; rather broad at the apex. 



From Synchita this genus may be distinguished by having the 

 basal joint of the antennse considerably larger than the following, 

 the head broad, deeply inserted in the thorax, the latter immarginate, 

 quadrate, with its hinder margin closely applied to the base of the 

 elytra, the body oblong-ovate, and in other less evident characters. 



Sp. 1. histeroides. Depressum, nigrum, nitidum, glabrum, antennis pedibusque 



rufo-testaceis, elytris obsolete punctato-striatis. (Long. corp. 1^ — 1| lin.) 

 Ly. histeroides. Panzer. — Ce. histeroides. Steph. Catal. 90. No. 967. 



Depressed, black, shining, glabrous : head finely punctured : eyes black ; mouth 

 and labrum ferruginous : thorax deeply punctate, immarginate ; the base ob- 

 soletely bisinuated ; closely applied to that of the elytra, the latter as broad as 

 the thorax anteriorly, the sides slightly dilated, the disc a little convex, ob- 

 soletely punctate-striated; the apex rounded: body pitchy-black beneath: 

 legs testaceous or obscure rufo-piceous. 



Varies a little in colour, according to its state of maturity ; being sometimes en- 

 tirely of a chestnut hue, or ferruginous, or testaceous.
