122 Descriptive Catalogue of the Coleoptera of South Africa. 



preceding one and transverse, eleventh hardly broader, truncate at 

 base, acuminate at apex and slightly turbinate ; prothorax broader 

 than the head, cordate, sinuate laterally past the middle, lateral 

 foveae large, median transverse sulcus much angulate, median fovea 

 almost wanting ; elytra much broader than the prothorax, longer 

 than broad, slightly rounded laterally, shoulders oblique, little 

 prominent, base with two foveae, dorsal sulcus disappearing before 

 reaching the median part ; metasternum minutely foveate in the 

 posterior part ; legs of moderate size, posterior trochanters slightly 

 produced and aculeate at apex, posterior tibiae a little thickened and 

 with an apical spur ; last ventral segment neither broadly nor 

 deeply impressed. Male. Length 1*80 mm. 



Closely allied to D. globulicornis ; the fourth joint of the antennae 

 is also thicker than the fifth, although not quite as much thickened, 

 but these two joints do not unite to form a knob as in D. globuli- 

 cornis, and the shape of the fifth joint is more rounded; it differs 

 from D. irregularis in the form of the fourth and fifth joints, which 

 are transverse instead of being elongato-quadrate ; it cannot be 

 mistaken for the male of D. concolor because the head is longer than 

 broad, whereas in the latter it is transverse, and the joints of the 

 antennae are longer than broad ; it cannot be compared with D. 

 gratitudinis, the fifth joint of which is much more dilated, while the 

 fourth is hardly so. In short, in both D. globulicornis and D. 

 elizabethana two joints, the fourth and fifth, are dilated, but in the 

 former these two joints form a common, slightly rounded node by 

 the superposition of the anterior and posterior margins respectively, 

 whereas in the latter these two joints are very free and distant from 

 one another; the colour is also much darker in D. globulicornis. 

 Female unknown.
