from there to the dechvity, which is very abrupt and angulate 

 dorsally; upper surface almost plane as far as interval 4, then 

 sloping steeply to interval 6, with regular rows of large deep fovese ; 

 interval 4 with a row of sharply conical tubercles terminating at the 

 top of the declivity with a larger agglomerated tubercle, 6 with similar 

 row of tubercles extending to the apex, 3 and 5 each with a basal 

 callus, and 2 with a row of small tubercles on the declivity. Legs 

 with dense brown scaling and short dark setae ; tibiae slightly 

 scabrous, the external apical angles roundly produced ; tarsi 

 moderately long and stout.

 Plate VI., fig. 7. 



Long. 7|- ; lat. 4| mm. 



Colour black, with more or less dense grey scaling and a few 

 short suberect setae. 



Prothorax as long as broad, sides with a slight subdorsal angula- 

 tion, which is visible only when the thorax is viewed obliquely and 

 not when seen directly from above, broadest near base, slightly 

 narrowed anteriorly and dorsally compressed towards apex, base 

 subtruncate ; upper surface somewhat convex behind, obscurely 

 punctured, with a transverse apical impression containing three 

 shallow foveae ; sides obscurely punctured. Elytra oblongo-ovate, 

 basal margin a little broader than the base of the prothorax and with 

 its external angles acute and slightly projecting, shoulders rounded, 

 sides slightly rounded, apical declivity steep and angulated dorsally ; 

 upper surface plane as far as the 4th interval, then sloping sharply 

 to the 6th, with irregular rows of large punctures ; interval 4 oblique, 

 approaching the suture posteriorly and with a row of small tubercles 

 ending at the declivity ; interval 6 with a row of rather larger 

 tubercles continued to apex, interval 2 with a small tubercle at the 

 top of the declivity, the basal calluses faint. Legs grey with brown 

 mottling and scattered dark setae ; tibiae not scabrous, the inner 

 apical angle* with a long curved spine, the outer angle slightly
