base of eiiual width (2-8 mm.); sides lightly sinuate posteriorly 

 and meeting base at right angles, bisetigerous — the posterior seta 

 a little before basal angle. Elytra depressed, strongly striate; 

 base bordered; lateral border interrupted near apex and with an 

 internal plica; 1st interstice with an elongate striole at base, 3rd 

 3-punctate along course of 3rd stria, 8th tinely carinate on apical 

 curve. Mesosternum with intercoxal declivity wide; epimera not 

 reaching coxje : metepisterna long. Legs (^) light : anterior 

 femora long, rather narrow; a short cylindrical hamiform process 

 (a hook with apex sharply bent towards base of femur) projecting 

 from lower side at about J of its length : anterior tibia? long, 

 narrow" on basal half, wide at apex, not curved: intermediate 

 long (longer than femora), strongly curved inwards; posterior 

 long, slender: anterior tarsi stout, joints not dilatate, 5th longest, 

 longer than three preceding together, basal joint much longer 

 than 2nd, squamulose in middle of lower side near apex, 2nd and 

 3rd joints with two narrow rows of squamse in middle of lower 

 side; four posterior tarsi narrow, cylindrical, posterior much 

 longer than intermediate; posterior coxa? contiguous. 



Rh.ebolestes walkeki, n.sp. 



(J. Elliptical, depressed, nitid. Prothorax small, lightly trans- 

 verse; elytra oval. Piceous-reddish-brown; lesrs and bodv redder 

 than upper surface. 



Head (with mandibles) elongate, not large (3*1 mm. across eyes); 

 e3'es reniform, sloping roundly and strongly to head in front, more 

 gently and obliquely behind; postocular part of orbits small, 

 sloping backward obliquely from eyes (the slope continuous with 

 that of e3^es), front bordered on each side by a distinct ridge 

 between eye and base of antenna; frontal impressions lightly 

 outturned and rather wide posteriorly, ending opposite middle of 

 eyes; spaces between frontal impressions and lateral ridges wide 

 and rather convex. Prothorax subcordate (3-3 x 3 7 mm. ), widest 

 at anterior 3rd (at anterior marginal seta); disc subconvex, 

 lightly declivous to sides and anterior angles, gently declivous 

 posteriorly to a wide transverse basal depression; sides lightly
