ii. 1906 (tvpe) ; 2 <? £, 1 ? , Valley of Kola R., 1500- 

 2000 ft., E" of Mt. Chiperone, iv. 1913 (Dr. S. A. Neave). 



In all Dr. Neave's specimens there is an additional large 

 pale patch on the apical declivity of each elytron (var. excla- 

 mationis, nov.). 



Protostrophus mucronatus, sp. n. 



$ ? . Colour piceous, with dense sandy and ash-grey 

 scaling, more or less mottled with dark brown ; sometimes 

 the paler scales and occasionally all of them are coppery 

 brown ; the prothorax with a sharply defined, broad, dark 

 brown lateral stripe which is invisible from above and is 

 continued on to the inflexed margins of the elytra as a more 

 or less indefinite stripe. 



Head separated from the rostrum by a short, slightly 

 curved, transverse stria ; the forehead gently convex trans- 

 versely, with a very short median stria uniting with the 

 transverse one and hardly extending to the centre of the 

 forehead, and set with obliquely raised spatulate setae, 

 the shallow confluent pnnctation being entirely hidden by 

 dense circular scaling ; the scales on the gular region sparse 

 and narrow ; the eyes moderately prominent, deepest slightly 

 behind the middle, the orbit narrow and not projecting on 

 the posterior edge. Rostrum a little shorter than its basal 

 width, the sides slightly sinuate ; the dorsum plane, with a 

 shallow median impression containing a mere trace of a carina; 

 the scales on the mandibles elongate ; the genae broadly 

 impressed. Antenna setose and not squamose ; the scape 

 slender and abruptly clavate ; the funicle with joint 1 

 nearly twice as long as 2, the remainder bead-like and trans- 

 verse, 7 the broadest. Prothorax moderately transverse 

 (4 : 3), broadest in the middle, the sides strongly and evenly 

 rounded, not emarginate behind the eyes ; the apical margin 

 gently convex dorsally, oblique at the sides ; the base as 

 broad as the apex, slightly rounded and scarcely marginate ; 

 the very shallow confluent pnnctation entirely hidden by the 

 scaling, with a very narrow bare median line ; the upper 

 surface strongly convex transversely and set with short 

 suberect spatulate seta 3 . Elytra comparatively narrow, 

 subelliptical, broadest about the middle, the base deeply 

 sinuate ; the striae shallow, the punctures in them only 

 faintly indicated through the scaling and each containing a 

 minute white seta, the intervals slightly convex and each 

 bearing a row of erect spatulate setae ; the scales very
