FSKLAPHIDAi;. 165 



inconspicuous, rather .short and sJendei', yellowish pubescence, but the 

 apices of the elytra and dorsal segments are thickly ciliate with elongate, 

 rather coarse, bright-yelloAv setae. 



Head as long as thorax, considerably narrcjwed beliind tlie vei-y pio- 

 minent eyes; the pair of large rotundate foveae, situated between the 

 eyes and base, are confluent with the depressed fi-ontal portion, the 

 occii)ut has an angular median emargination at its base. Ihorax rather 

 broader than long, iiarrower than elytra, I'ounded and widest at the 

 middle, very abruptly contracted and .straight-sided behind, obliquely 

 narrowed anteriorly; basal median fossa large and deep, tapering to- 

 wards tlie front, and terminating as a fine stria near the apex; the 

 lateral foveae extend foi'ward as far as the middle, and from the inner 

 margin of each a linear impression proceeds straight forward to the 

 narrow frontal portion; the connecting transverse stria near the base 

 is somewhat indefinite. Elytra a third broader than long, longer than 

 the thorax; the shoulders rounded, each with a minute prominence 

 behind, so that the side of each elytron appears sinuously narrowed befoie 

 the middle; sutural striae well marked, foveiform at the base, with a 

 slight plica l)etween each and the deep broad impression inside the 

 shoulder. Hind-body quite as long and almost as bi'oad as elytra, 

 basal three segments marginate and subequal, the others deflexed, the 

 1st with a transverse basal depression. 



Legs stout, distinctly punctate and pubescent ; anterioi- and posterior 

 tibiae a little incrassate below the middle, rather deeply excavate near 

 the extremity-, these cavities sharply margined, the intermediate i>air 

 grooved externally, so tliat in both sexes the liasal joint of the tai'si is 

 almost concealed. 



Male. — Antennae stout, finely pubescent, e(|naning tlie head and 

 thorax in length; basal joint not twice as long as broad, 2nd fully as 

 thick, moniliform, rather broader than long, the next smaller, also 

 bead-like; joints 4 to 7 transverse, slightly increasing in breadth, 8th 

 evidently shorter and a little broader than the preceding ones; 9th sulj- 

 quadrate, very large, almost wholly concave underneath; 10th small, 

 hardly any larger than thii-d; terminal joint elongate-conical an<l 

 acuminate, rather narrower but more elongate than the 9th. 



Underside of head with numerous long erect setae, and a deep 

 rotundate basal fovea. Prosternum carinate along the middle. Meta- 

 sternum short and convex. Basal ventral segment covered by the femora 

 but distinctly fringed behind, segments 2-4 sube(iual, 5th shorter, 6th 

 emarginate behind, 7th moderate, with a central oblong operculum. 



Maxillary palpi with the 2nd joint elon<i:ate, blender near the base, 

 clavate at the extremity, 3rd stout and subtriangular, 4t]i ])nl)escent,. 

 lather slender and elongate, slightly oval, not securiform. 



Fern. — With 6 ventral segments. .Joints 4-8 of the antennae trans- 

 versely monilifonn and differing but little, 9th rather larger than ,10th; 

 the sides and apices of elytra fuscous. In other dotaHs like the male. 



Tliis is almost a giant amongst the ordinary Euplecthii . '\\nien 

 conq)ared with B. puhef^cens, 244, this is .seen to be larger, it is nearlv 

 concolorous, quite perceptibly punctate, and with different vestiture. 

 The head is more elongate, with more convex, outstanding eyes. The 

 abrupt contraction of tlie l)asal portion of the thorax cau,ses the hind 

 part iif the dilated middle portion to appear angulate. There is a 

 lateral sinuosity behind each slioulder. The remaikable tibial excava- 

 tions are very distinct. The teiiuinal joint of the maxillary palpi
