reaching the base, the outer ones subiDarallel, finely aciculate and 

 with sparse pale scaling. Antennce slender, piceous, with thin 

 pale pubescence ; scape distinctlj'- bisinuato, compressed and 

 gradually thickened to apex ; third joint of funicle much longer 

 than first, subterminal joints elongate. Protliorax very transvei-se, 

 the base broadly rounded, sides straight and rapidly converging 

 from base to apex, which is truncate, posterior angles acute ; 

 upper surface rather convex, moderately closely granulate, with a 

 shallow depression on each side near the base ; colour black, 

 granules bare, the interstices with yellowish-white scaling which 

 is denser lateially. Elytra broadly ovate, acuminate posteriorly, 

 jointly sinuate at base and a little broader than the protliorax, 

 shoulders acute, sides strongly rounded, broadest before middle ; 

 upper surface slightly convex, the suture distinctly elevated and 

 the sides strongly inflexed, the strife deep latei'aliy but shallower 

 on disk, containing rows of shallow punctures separated by minute 

 granules ; the intervals finely coriaceous and with a few scattered 

 granules on the declivity ; interval 1 elevated, 2 plane, broadei- 

 than the rest and subdepressed near base, 3 and 4 slightly 

 convex, 5, 6, and 7 narrower and subcarinate, those on the 

 inflexed margin plane ; colour piceous, almost bare, with very 

 fine thin grey scaling. Legs slender, piceous, with fine short 

 white pubescence, the anterior tibiae only slightly curved. 



Type 5 in the Stockholm Museum, 



Caffraria {J. Wahlherg). 



The type is the only example which I have seen of this species. 

 The strong lateral inflection of the elytra, in conjunction with 

 the elevated suture and depressed second interval, gives the 

 insect a very distinctive facies.

Long. 5i-5i, lat. 24-24 mm. 



Head moderately ti'ansverse, convex, finely and longitudinally 

 plicate, with thin grey scaling ; forehead without imjDressions ; 

 eyes not prominent. Rostrum about as long as broad, sides 

 subparallel to near apex, gena; slightly and roundly dilated ; 

 upper surface plane, rugosely punctured, with three fine carinas, 

 the outer ones straight and parallel. Antennce moderate ; 

 piceous, with fine grey pubescence ; scape broad, compressed, 

 strongly curved and gradually dilated to apex ; funicle com- 

 paratively short, the third joint longer than the first, the outer 

 ones elongate but subconical. Protliorax twice as broad as long, 

 arcuate at base, apex truncate and much narrower, sides sub- 

 angulate near base and rapidly narrowed from there to apex ; 

 upper surface evenly coriaceous, without any lateral basal 

 impressions ; colour black, with thin grey scaling which is rather 

 denser beneath. Elytra ovate, somewhat acuminate posteriorly, 

 jointly sinuate at base, sides moderately rounded, broadest befoi'e 

 middle ; upper surface not very convex, with fine stride containing
