impression close to the basal margin ; the upper surface 

 rather flattened and with fine sparse punctures on the disk, 

 those in the basal impression and at the sides very coarse, 

 being much broader than the spaces between them. Elytra 

 subcylindrical, rather broader than the widest part of the 

 prothorax, the basal margin gently sinuate, its external angles 

 rounded, and the sides shallovvly constricted before the apex ; 

 the disk scarcely striate, but with rows of fovea? separated 

 longitudinally by spaces about as long as the fovea? themselves, 

 the rows becoming striate externally and behind and with the 

 punctures more closely placed ; the intervals with sparse 

 minute irregular punctures, plane and as broad as the fovea? 

 on the disk, but becoming slightly costate towards the sides 

 and apex, the junction of the second and tenth intervals at 

 the apex only slightly elevated. Legs with the femora finely 

 and sparsely punctate and not with coarser punctures towards 

 the apex ; the tibia? not armed internally with the usual long 

 teeth, but with short serrations, the posterior pairs being 

 scarcely sinuate internally, and the apical external tooth very 

 short on all the tibia?; the second joint of the front tarsi 

 broader than long. 



Length 8 mm., breadth 3 mm. 

 Angola: Benguelhi (Coll. Pascoe). 

 Type in the British Museum. 



Superficially resembles A. anthracinus, but differs from all 

 the species known to me in its coarsely punctate elytra and 

 in having the forehead narrower than the base of the rostrum.

J. Colour light reddish brown, shiny, with the apex of 

 the prothorax and the tips of the femora darker; the body 

 entirely devoid of scales or seta?. 



Head very sparsely punctate, the forehead rather broader 

 than the base of the rostrum and with a large central fovea. 

 Rostrum about as long as the prothorax, stout, rather strongly 

 curved, cylindrical and not dilated at the apex ; the punctation 

 fine and rather sparse, but coarser at the sides in the basal 

 half; the antenna? inserted at one-fourth from the apex. 

 Prothorax slightly broader than long, strongly rounded at 

 the sides, broadest about the middle, sharply narrowed at the 

 apex but scarcely constricted, the base truncate and shallowly 

 depressed below the level of the disk ; the upper surface 

 markedly flattened, with small deep punctures on the disk, 

 which are narrower than the spaces between them, those at 

 the sides much finer and shallower. Elytra a little more than
