Miilest ;in<l iimnded bft'oie the middle; di.scal dt'i>rossion subqiiadrute, 

 basal punctui^es small, lateral foveae also small, not extending forwards 

 as far as tlie middle. Elytra suboblong, a third longer and, Ijchind, 

 equally bmailer than the thorax, very gradually narrowed towards tlie 

 base; they are very slightly depi'essed before the middle, with well- 

 marked sutural striae, the dorsal are half the whole length, each is com- 

 posed of a basal puncture and elongate impression. Hind-body rather 

 longer than the elytra, slightly l)roader in line with tlie .'jid visible 

 segment, which is slightly lojiger than the 2nd, -itli and ."jth deflexed, 

 the l)asal bt'ars minute bi'assy squamae. 



Antennae thick, rathei- longer than the head and thorax, bearing 

 slender grey setae; basal joint twice as long as broad, the next obconical 

 and half as long, 3rd smallest, subglobose or obconical; joints 4-10 of 

 about equal size, evidently broader than the '3rd, 4th and 5th more or 

 less obconical, G-10 subquadrate, 6tli and 7th slightly bi'oadei- tlian 10th, 

 terminal conical. 



Legs rather elongate, tibiae very slightly arched externally. 



Male. — Underside chestnut-red, with elongate yellow jDubescence. 

 Metasternum moderately short and convex. Abdomen elongate, the 2nd 

 segment rather shorter than the 3rd ; 4th longer, slightly but widely 

 emarginate behind, depress-ed in the middle, and at the ajjex with a pair 

 of prominent tubercles which are directed upwards and backwaids; 5th 

 with a median depression and emarginate beliind, 6tli slightly and 

 obtusely prominent at each side, the operculum broadly conical. 



The body, from the apex of the 3rd dorsal segment to the base of 

 the elytra, is Pselap/itis-like, being gradually narrowed anteriorly. It 

 differs from S. m/'selh/, 248, in having the head and thorax narrowei- 

 and the elytra longer. The frontal channel is decidedly narrower, 

 especially in front, the antennae are stouter, with more quadrate joints, 

 and the erect hairs on the body are evidently more elongate. The 3rd 

 ventral segment in .S'. prisca is bituberculate.

Small, elongate, subdepressed, nitid ; light chestnut-i-ed, legs and 

 antennae fulvescent ; witli distinct, but not elongate, decumbent, greyish- 

 yellow pvd^escence. 



Head smaller than the thorax, narrowed in front, genae short, nearlv 

 straight, with o])tuse hind angles; antennal tubei-cles small, slightly 

 elevated and distant, the surface nearly plane, moderately finely punctate, 

 with small, indistinct interoculai- foveae. Thorax slightly longer than 

 broad, oviform, moderately rounded and widest near the middle, its 

 punctation not coarse, nor close, and somewhat irregular; lateral foveae 

 oval, extending forwards to the middle and joined to the transverse basal 

 fossa by a groove, iliscal stiia abbi-eviated, not reacliing the front or the 

 basal depression. Elytra subquadrate, longer and broader than the 

 thorax, curvedly narrowed before the middle so that the base is but little 

 bi-oader than that of the tliorax; indistinctly punctate, the broad sutural 

 striae are punctiform at the base, dorsal striae also broad, tapering 

 towards the middle and not attaining the extremity. Hind-body as long 

 as the elytra, finely and on some parts closely punctured; basal three
