Hah. Cape Colony (Willowmore). 



A very distinct species, which should follow D. pulcher, Catal. i., 

 p. 790. 



DlCEANOCNEMUS ARDUUS, n. spec. 



Head and prothorax black ; elytra, underside and legs rufescent ; 

 clypeus truncate in front, slightly angular laterally, head and clypeus 

 deeply and closely punctate, the punctures scabrose on the sides 

 only, clothed with a very short, greyish not scaly pubescence, and 

 moderately deeply grooved longitudinally ; scutellum pubescent ; 

 elytra short, narrowed behind, sub-costulate, clothed with elongated 

 flavescent scales not set closely and not hiding the red background ; 

 propygidium and sides of abdomen covered with flavescent scales ; 

 pygidium closely covered with thick scales which are somewhat 

 fulvous on each side of the basal part, and looking, on that account, 

 not unlike two faint fulvescent patches. 



This species has more the facies of an Heterochelus than any of its 

 congeners, on account of its being slightly more elongated in pro- 

 portion to its width ; the median claw is simple underneath, and the 

 hind ones cleft laterally inwardly. 



Length 4 mm. ; width 2 mm. 



Hob. Cape Colony (Uitenhage). 



Closely allied to D. pulverulentus, but without any scales on the 

 prothorax ; those of the elytra are also more scattered and of a 

 different colour. 



Gen. MONOCHELUS, Cat. i., p. 828. 

 Monochelus sag^:, n. sp. 



Male : Black, opaque on the upper side, under side shiny ; 

 clypeus truncate in front with the anterior margin reflexed, parallel, 

 briefly bristly along the edges, head and clypeus sub-scabrose 

 punctate ; antennas black ; prothorax as broad as long, strongly 

 sinuate laterally in the posterior part above the sharp basal angle, 

 deeply grooved in the centre from near the median part to the base, 

 closely aciculate, and having in the median longitudinal groove, 

 and also on the outer margin, a few white scales ; scutellum 

 clothed with white, sub-oblong small scales ; elytra attenuated 

 behind, non-costulate, vaguely aeiculated ; pygidium vertical ; scale- 

 less ; upper side of abdomen with a lateral band of white scales, a 

 similar but narrower band of scales edges the metasternum all round ; 

 anterior tibiae tri-dentate outwardly, the teeth are distant, the claw 

 of the intermediate tarsi is simple ; the hind femora are greatly 

 developed and dentate inwardly at the knee, the trochanter projects
