246 MANDIBULATA, — COLEOPTERA. 



Genus CCXIX. — Ceratophytum, Leach. 



Antenna rather long, pectinated on the inner side in the males, serrated in the 

 females; the third joint with the pectination longer than the rest; the apex 

 rounded, incrassated. Palpi, maxillary with the last joint very much in- 

 crassated, oval, somewhat obliquely truncate: maxilla; bilobed: mandibles 

 entire : body oval ; depressed : tarsi with the last joint bifid. 



Ceratophytum of Leach — Cerophy turn of Latreille — is to be 

 distinguished from the allied genera by having the antennae of the 

 males considerably pectinated ; the maxillary palpi with the terminal 

 joint very thick, oval, and somewhat truncate ; the maxillse bilobed, 

 the mandibles entire; body depressed; tarsi with the last joint 

 bifid. 



+ Sp. I. Latreilhi. Nigrum, elytris striatis, thorace subconvexo, antennis nigri- 



cantibus. (Long. corp. 3 ? lin.) 

 Ce. Latreilhi. Leach MSS.—Steph. Catal. 121. No. 1226. 



Black, elytra striated; the thorax slightly convex; the antennae and legs dusky- 

 The insect to which the above name has been applied is in the collection at 

 the British Museum; but some doubt hangs over its identity with the Cero- 

 phytum elateroides of Latreille, as its characters appear rather to partake of 

 those of the genus Eucnemis than the Cerophytum ; but I have not at this 

 moment the opportunity of examining the insect in question ; therefore I am 

 compelled to notice the suspicions which have been pointed out to me by 

 Mr. Westwood, until I am enabled to inspect the specimens. 



The specimen above alluded to, with others, was taken by Mr. 

 Millard, I believe, in the neighbourhood of Bristol. 



Genus CCXX. — Eucnemis, Mannerheim. 



Antennae slightly serrated, approximating at the base ; the basal joint elongated; 

 the second minute; the third longer, subcylindric ; the remainder cup- 

 shaped, and rather increasing to the extremity ; the terminal joint oblong- 

 ovate, acuminate. Labrum membranaceous, nearly entire: mandibles uni- 

 dentate : palpi thickened towards the apex, with the terminal joint oblong- 

 ovate, subsecuriform : maxilla; bifid : labium subemarginate : head deflexed : 

 thorax truncate anteriorly; bisinuated behind; closely applied to the base of 

 the elytra, which are slightly attenuated : legs short ; femora compressed ; 

 tarsi with the basal joint large, elongate, the remainder short. 



The chief characters of the genus Eucnemis, according to Man- 

 nerheim, consist of the approximating antenna, which have the first
