the posterior sloping part by minute granules ; legs glabrous, closely 

 punctate. 



In general appearance this species resembles more a Megacantha 

 than an Hoplonyx, but the four penultimate joints of the antennae 

 .are not moniliform as in Megacantha. 



Length 18 mm. ; width 7 mm. 



Hab. Southern Ehodesia (Matopo). K. Pillans. 



HOPLONYX GBATULUS, n. sp. 



Black, head and prothorax opaque, elytra sub-opaque, and with a 

 faint metallic lustre ; head covered with deep, sub-rugulose con- 

 tiguous punctures, eyes separated by a space equal to their own 

 width, supra-antennal crests strongly developed ; prothorax nearly 

 as long as broad, almost parallel, but slightly obliquely attenuated 

 laterally near the anterior angle, equally covered with deep, round 

 punctures separated by a very narrow raised wall, base without a 

 marginal groove ; scutellum ogival, short, punctate ; elytra sub- 

 parallel, but slightly sinuate laterally between the humeral and 

 median parts, closely and moderately deeply punctate-striate, inter- 

 vals plane, faintly aciculate, the punctures in the juxta-marginal 

 striae are broad and deep from the basal to the median part ; under 

 side closely punctate, sub-opaque. 



Length 7^ mm. ; width 3i mm. 



Hab. Southern Ehodesia (Enkeldoorn), J. ffoliot Darling. 



HOPLONYX EEFERTUS, n. sp. 



Black, head and prothorax opaque, elytra shiny ; head punctate, 

 antennal crests oblique, very long, space between the eyes in the 

 middle of the vertex about equal to one-third of their width ; 

 prothorax twice as broad as long, very faintly punctate, roundly 

 attenuate laterally from the apex to near the median part, straight 

 thence, carinate, strongly bi-sinuate along the base which bears a 

 very fine and not always very distinct groove along the median part ; 

 scutellum triangular, punctate ; elytra not wider than the prothorax 

 at the base owing to the shoulders being very sloping, nearly parallel 

 for two-thirds of the length, attenuate thence to the apex, narrowly 

 and closely punctate-striate with the intervals plane in the anterior 

 part, faintly convex in the posterior, and having very faint traces of 

 a slight aciculation. 



This species is easily distinguishable from the other South African 

 ones by the very broad prothorax, and the sloping shoulders of
