1897.] of the Coleoptera of South Africa. 71 



moderately elongate, two large foveae behind the eyes and also two 

 slightly arcuate sulci connected in front, antennal tubercles foveate, 

 vertex sinuate and slightly impressed near the neck ; antennae thick, 

 second joint subquadrate, third briefly obconical, fourth to tenth 

 hardly decreasing in width, fourth to eighth large, and ninth to tenth 

 less transverse and subquadrate, eleventh not broader than the pre- 

 ceding one, but much longer, truncate at base, acuminate at apex ; 

 prothorax hardly longer than the head but broader, ampliated 

 laterally in a rounded shape at about the median part, constricted 

 and sinuate from there to the posterior part, lateral foveas strong, as 

 is also the transverse sulcus, which is angulate in the median part, 

 median fovea strong, longitudinal sulcus more or less defaced and 

 abbreviate, sometimes obliterated, intermediate fovea merely sulci- 

 form ; elytra more or less obsoletely and dispersedly rugoso-punctate, 

 sometimes nearly smooth, longer than broad, shoulders defined, 

 oblique, and dentate, sides slightly rounded, dorsal sulcus disappear- 

 ing towards the median part ; abdomen shorter than the elytra, 

 first dorsal segment not longer than the others, the two carinules 

 very diverging and little distant at base. 



Male : Posterior trochanters with an inward, short, compressed, 

 incurved tooth, intermediate and anterior ones slightly angulate at 

 base, intermediate tibiae with a short apical spur ; last ventral 

 abdominal segment strongly impressed, and slightly tuberculate in 

 the middle of the base ; metasternum impressed. 



Female : Last ventral segment of abdomen compressed on each 

 side and having a small, horn-like process at apex, last dorsal 

 one obtusely tuberculate at tip ; metasternum convex. Length 

 1-90-2 mm. 



This species varies much in colour, the longitudinal sulcus of the 

 prothorax is also variable, being at times entirely absent, or reduced 

 to an oblong, median fovea. Not having had at first a long series of 

 examples to examine, I was led through these variations to believe 

 that there were two different species, i.e., majorina and pallidula ; 

 but I have been able since to examine more specimens, and I have 

 ascertained that the two are only one species. 



With this species begins the group in which the first dorsal 

 segment of the abdomen is not larger than the following ones.
