Approximately each disc has altogether about forty-five spines 

 including the smaller sutural ones. Each margin from the 

 humeral to the apical sutural angle has about twenty pointed 

 spines of equal length equally distant from each other, except 

 three on the apical area, which are larger and stouter. 

 Underside dull, with scattered white hairs. The femora 

 without teeth on the underside. Mid-tibia? slightly curved ; 

 the tarsi are long ; the claw-joint projects beyond tlie bilobed 

 joint. 



Length 4£ mm. 



Cape of Good Hope, Table Mt. {W. Bevins) (type). 



Type in the British Museum. 



There are three more specimens, more or less imperfect, 

 strongly resembling the type-specimen, with the following 

 label : — " Howick, Natal (J. P. Cregoe)." Much reliance 

 should not be placed on the authenticity of this locality. 



Acmenychus planus , sp. n. 



Body oblong, black, subnitid. The first joint of antennas 

 with a long dorsal spine. The claws fused together and as 

 broad at base as at the apex. Each side of the prothorax 

 with three single spines. Two pairs of spines on the front 

 margin are so far apart that they may be regarded as almost 

 lateral. The dorsal side of the elytra without any prominent 

 well-defined ribs or tubercles. 



Head broad rugose, with an interantennal ridge and a row 

 of silvery hairs encircling each eye. Collar very finely 

 granulate. The first joint of the antenna? is the largest, the 

 second small and rounded, the third to sixth of gradually 

 diminishing length. The six basal joints are subnitid, 

 strongly sulcate, and with a few scattered silvery hairs ; the 

 five apical joints form an elongate club and are covered with 

 brownish pubescence. Prothorax almost as broad as long, 

 broadest across the middle and slightly narrowed anteriorly 

 and posteriorly. The sides are rounded. The surface is 

 rugose, with scattered silvery adpressed hairs and with a 

 longitudinal smoother area with an impressed median line. 

 There are also two shallow transverse depressions, the poste- 

 rior one being deeper than the anterior. Scutellum quadrate, 

 with apex rounded, the surface very finely granulate. Elytra 

 broader than the prothorax at the base, punctate-striate ; the 

 punctures, coalescing, become larger and coarser in the middle 

 and in the apical area. Comparatively speaking, there are 

 no prominently raised costaj ; on the other hand, the inter- 

 stices are not quite plain on the apical area of the disc — they
