sex ; propygidium with a narrow median space very indistinctly 

 scabroso-plicate ; legs and under side as in Syrichthus ; anterior 

 tarsi not much thickened, and with the claws equal in both 

 sexes. 



The only species included in this genus is found in decayed tree- 

 trunks.

Plate XL., fig. 2^ 

 Handb. d. Entom., v., 1847, p. 168. 



S. cribratus, ? Bohem., Insect. Caffrar., ii., p. 6. 



Piceous black, seldom quite black, moderately shining, densely 

 fringed along the whole of the outer margin of the prothorax and 

 half of that of the elytra with very dense, long, fulvous hairs, as in 

 Syrichthus verus ; head rugose, clypeus sharply recurved at middle 

 and with a short sharp tubercle in the median part in the male, and 

 a transverse carina slightly aculeate at middle in the female ; 

 pi'othorax depressed in both sexes, but covered with broad, deep 

 punctures ; in the male there is in front a semicircular, deep 

 impression enclosing a triangular median tubercle, and the pos- 

 terior part of the disk is sometimes deeply grooved ; scutellum 

 impunctate ; elytra sub-parallel, depressed, very roughly and closely 

 punctate, with the strite single, moderately distinct, and indicated in 

 fresh examples by long, remote, rufescent setae, as in SyricJithus 

 verus ; pygidium deeply foveolate ; under side very villose. 



Length 13-21 mm. ; width 7-11 mm. 



Boheman's S. cribratus is a small female in which the villosity 

 has disappeared, and his Syrichthus spiirius is identical with 

 Orsilochus cornutus. 



Hab. Cape Colony (Cape Town, Stellenbosch, Knysna), Bechuana- 

 land (Kuruman). 



SYEICHTHOMOEPHUS, n. gen. 



Mentum a little rounded laterally from the base to a third of the 

 length, gradually attenuate from there to the apex, and with the 

 ligular part hardly constricted laterally, and only slightly emarginate 

 at tip, it is impressed on each side at the base, and the ligular 

 part does not recede much, but is deeply concave ; maxillae and palpi 

 similar to those of Pseudosyrichthus and Syrichthodontus ; head 

 similar ; prothorax convex and with a marginal tubercle in the 

 anterior part, and a very deep median groove in the female, the only 

 sex known ; elytra convex ; no stridulating organ on the propy-
