BoLiTONiEUS, gen. nov. 



Type B. mergce. 



I propose this genus to receive some small species which 

 vary in size from about 4 to 6 mill.; most of its characters 

 are those common to Atasthalus ; the antennae have seven 

 rather short and sometimes robust [B. mergiv) moniliform 

 joints, sometimes the joints are much more slender {-^-den- 

 tatus), eighth to tenth more or less transverse, eleventh with 

 the base somewhat embedded in the tenth; the maxillary 

 palpi slender, terminal joint rather long ; the eyes, ocular 

 ridge ceases abruptly in the middle of the eye-disk, the ridge 

 when viewed from above gives the eye the appearance of 

 having a small tubercle in its centre. The prosternum is 

 depressed posteriorly and the mesosternum somewhat short. 

 Bolitophagus vacca, Motsch., Ileledona nasalis, Pasc, and 

 Bolitotherus A-dentahis^ Cand., should be placed in this genus. 

 The type of Bolitotherus {Phellidius, Lee), Candcze, is an 

 American species, B. cornutus, F., which has an antenna of 

 ten joints only ; but Candcze also included in it B. -i-dejitatus, 

 which has eleven joints to tliese organs. Pascoe's note 

 (Ann. & Mag. Nat. Hist. 1871, viii. p. 348) regarding Bolito- 

 therus may be cancelled, as the note was written, as he 

 informed me, under the impression that B. cornutus, F., was, 

 as indicated in the Munich Catalogue, a Ceylonese insect. 



Bolitonceus mergce^ sp. n. (PI. XIII. fig. 5.) 



Oblongus, parum cylindricus, obscure brunncus ; thoracc marginibus 

 crenato, S comibus duobus horizontalibus ad apicem dense rufo- 

 hirtis. 



L. 4-4| mill. 



Oblong, dull brown or blackish brown, opaque ; the iiead 

 very rugose, frontal margin roughened on the edge, with a 

 small denticle near the antenna in well-developed males ; the 

 thorax rough, nodulous, laterally crenate, with two median 

 horizontal horns, reaching in fine examples beyond the head 

 by half their length, incurved from their bases, apices densely 

 clothed with reddish hair ; the elytra, interstices rugose, with 

 eight or ten rows of small nodules on each wing-case, but 

 this sculpture suffers much from abrasion and is often obsolete. 

 The antennae rather stout, seventh and eighth joints rather 

 transverse, ninth, tenth, and eleventh forming a club ; the
