1897.] of the Coleoptera of South Africa. 77 



Male : Metasternum and also last ventral segment broadly im- 

 pressed. 



Female : Metasternum convex, last dorsal segment minutely tuber- 

 culate at apex. Length 1-40-1-60 mm. 



Closely allied to the preceding species, but the head is longer, 

 slightly narrowed in front, with the tubercles much smaller ; the 

 prothorax is cordiform and very variable ; in some specimens the 

 head and prothorax are coarsely punctured, in others they are 

 smooth. 



Not rare in the neighbourhood of Cape Town and Newlands. 

 The examples from Newlands have generally the head and pro- 

 thorax punctured, and those from Cape Town smooth. 



Eaffrayia obscura. 



Somewhat elongate, not much thickened, black, with a rather 

 dense but brief pubescence, a few of the hairs dispersed, long and 

 recurved ; legs and antennge piceous, last joint of the former 

 lighter, tarsi and palpi testaceous ; head small, elongate, slightly 

 attenuate in front, two foveas between the eyes, which are large, 

 sulci oblique, antennal tubercles divided by a strong, transverse 

 sulcus, vertex somewhat convex, briefly carinate close to the neck ; 

 antennae rather elongate, a little thickened but not at all at 

 apex, first joint elongate, cylindrical, second quadrate, third to 

 seventh slightly transverse, eighth to tenth subquadrate, eleventh 

 middling, subturbinate and acuminate ; prothorax much broader, 

 hardly longer, cordate, lateral foveae large, median one minute, 

 transverse sulcus strong, angulate, impressed at base ; elytra large, 

 shoulders well defined, oblique, obtusely dentate, slightly rounded 

 laterally, strongly bifoveate at base, dorsal sulcus shortened in the 

 middle ; abdomen a little smaller than the elytra, dorsal segments 

 equal and having the carinas short, inclosing only the fourth of the 

 length of the disk, and having between them a deeply impressed 

 space. 



Male : Head subgibbose underneath and slightly impressed on 

 each side before the eyes ; metasternum deeply sulcate longitudinally, 

 last ventral segment slightly impressed. Length 1-50 mm. 



Eesembles much R. microcephala, but differs by the darker colour, 

 the longer head, the more slender antennae and the shorter and more 

 approximate abdominal dorsal carinulae. 



Hab. Cape Colony (neighbourhood of Cape Town — Muizenberg 

 Vlei). One male only.
