DescrijJtive Catalogue of the Coleoptera of South Africa. 175 
A^ Prothorax without any discoidal impression on each side ; punctures on 
the upper side very fine and very closely set ; posterior angles of the 
head not bulging out in the male rhodesiana. 
Synhoria hottentota, Pering., 
Plate XXII., fig. 2, 2a, 2b. 
Trans. S. Afric. Phil. Soc, iv., 1888, p. 134. 
Bright red, palpi, antennae, tibiae and tarsi black, apical part of the 
mandibles deeply infuscate. In the male the elytra have occasionally on 
each side a small juxta-scutellary and a sub-humeral black spot, two 
post-median spots or dots between the second costa and the outer margin, 
and a similar one above the apex in the first interval ; these black spots 
are somewhat asymmetrical. Head deeply punctate and very briefly 
pubescent, the punctures are more closely set in the female than in 
the male, in the latter the basal part of the sides project strongly ; 
prothorax deeply and closely punctate, and briefly pubescent, the pube- 
scence, however, being longer laterally in the female than in the male, it 
is longer than broad in both sexes, in the male it is narrowly grooved in 
the centre from the base to a short distance from the apex and has on 
each side a deep impression, whereas in the female it is grooved from the 
base to the apex and is much less conspicuously impressed on each side of 
the disk ; scutellum punctulate ; elytra deeply punctulate, the punctures 
are almost contiguous, and the intervals slightly raised, thus imparting to 
the elytra a faintly shagreen ed appearance, the two dorsal costse are very 
distinct, and the pubescence is very short, but very dense ; under side and 
legs closely punctate, pubescent. 
Length (excl. of mandibles) 21-32 mm. ; width 6-11 mm. 
Hab. Cape Colony (Cape Town, Worcester, Knysna) ; Natal (Dur- 
ban) ; Damaraland (Goagas) ; Ovampoland. 
Two examples from Damara are a little darker in colour than the Cape 
and Natal examples the males of which have also a longer pubescence 
on the prothorax. 
Synhoeia rhodesiana, n. sp. 
Male : Brick red with the apex of the mandibles, the antennae, and the 
basal part of the femora black ; head and prothorax not distinctly pube- 
scent, the pubescence on the elytra is extremely fine, and the latter has 
two rudimentary fuscous, asymmetrical spot-like patches on each side near 
the base ; head straight laterally behind the eyes, the longitudinal central 
groove is visible in the centre of the frontal part only, the punctuation is 
very fine and is to be seen only on the sides ; prothorax very transverse, 
plainly pubescent laterally, covered with somewhat remote fine punctures
