82 CLAVicoENiA. [Ewmcrur. 



cylindrical, as long as the two following, anJ thicker, joints 9-11 forming 

 a gradual and not very marked club; thorax longer than broad, im- 

 punctate, feebly rounded and widened before middle, with four fovesa 

 at base ; elytra oval, convex, much broader than thorax, very finely and 

 obsoletely punctured, each with a distinct fovea at base ; femora clavate, 

 thickened towards apex ; posterior trochanters elongate. L. 2 mm. 



Male with intermediate tarsi feebly, and anterior tarsi strongly, 

 dilated. 



In hnystack ami vegetable refuse, cut grass, dung-heaps, under stones, &c. ; 

 ponerally distributed and common tliroiigbout the Loudon and southern districts and 

 the niid'ands ; rarer further north ; Northumberland and Durham district, rare ; 

 iSeotLtiid, rare, Sohvay and Tweed districts. 



Z:. rufus, ]\IiUl. (iiffilis, Mots. ; Cholems rnfti.9, Thoms.; Heterognathvs 

 rufiis, King). A small convex species, of a rufo-testaceous colour, with 

 rather fine yellowish pubescence ; head large, antennae moderately long, 

 Avith the last three joints forming a club, the two pentdtimate ones 

 being about as long as broad ; thorax ovate cylindrical, slightly longer 

 than broad, without fovete at base ; elytra short oval, much broader in 

 the middle than thorax, very finely but visibly punctured ; femora 

 clavate, strongly thickened towards apex ; the mctasternum is very long, 

 and the hind legs vicAved from above appear to start from the apical 

 portion of the elytra ; this is the case, to a somewhat lesser degree, 

 with E. tarsatus ; the sexual differences appear to be very slight. L. 

 1^ mm. 



Under bark, and in damp wood mould ; very rare ; two specimens only have 

 occurred in Britain, one taken liy Mr. Champion in Kichniond Pai-k, Surrey, in 

 March, 1871, and a second which was kindly given me by Mr. E. A. HutUr, who 

 captured it in 1882 at Hurst Green, Sussex, a village near Ktchincham Station on the 

 S.E. railway; he found it on his little girl's dress, after she had been playing in a 

 field for some time, so that it evidently came out of the grass, and might peihaps be 

 obtained by sweeping in the locality ; it is found not rarely in some parts of Enrojie 

 under bark and in rotten stumps with ants. This species and U. tarsatus certainly 

 seem to belong to diflereut genera. 



CEPHENNIINA. 



The genera belonging to this tribe are very distinct from the rest of 

 the Scydma3ni(;l8e in general appearance by reason of tlie l)road thoi'ax 

 which is aljout as wide at base as the elytra, so that the insects present 

 a continuous outline; in the genus Euthin, moreover, the elytra are 

 truncate and leave the pygidium exposed ; the maxillary palpi, as in the 

 Eumicriua, are apparently 3-jointed, the fourth joint being very short 

 broad and obsolete, and rounded in conjunction with the third joint ; 

 two of the three European genera are found in Britain. 



J. Apex of elytra truncate, pygidium exposed ; base of thorax 



with five foveas EuxniA, Stt-ph. 



II. Apex of elytra rounded, pygidium covered; l.ase of thorax 



without fuvia; CEPUENNirM, MiiU.
