PJujtflphagoKs Colpoptera from various regions. 41 



Head impunctate, flavous ; antennae ftiseous, the basal joints more or less 

 flavous ; thorax strongly transverse, the sides narrowed at the base, rounded 

 before the middle, the disc impiinctate, with a transverse groove which 

 extends nearly across the entire disc ; sciitellum black ; elytra widened 

 towards the middle, very closely and finely punctured, reddish fulvous, all 

 the margins narrowly black, as well as a narrow transverse band, placed at 

 the middle, of somewhat curved shape, and joining the lateral and sutural 

 margins ; under side black, shining ; the femora, base of the tibiae, and the 

 last abdominal segment, flavous ; the sides of the abdomen also more or less 

 spotted with flavous. 



Hab. Transvaal ; also Zambesi Eiver. 



The pattern of the elytra of this species differs from any of 

 its congeners ; the antennae in one of my specimens are nearly 

 entirely fulvous. 



Idacantha punctatissima, n. sp. 



Fulvous ; the antennae (the basal three joints excepted), the legs, and 

 the elytra, black ; thorax very sparingly and finely punctured ; elytra 

 strongly and closely punctate. Length, 3 lines. 



Head (impunctate, the vertex with a small fovea, the frontal elevations 

 narrowly transverse, the carina broad ; palpi black, the penultimate joint 

 widened ; antennae black, the basal three joints and the base of the fourth 

 joint fulvous ; thorax rather strongly widened at the middle, fulvous, very 

 finely and sparingly punctured, the disc with a transverse medially inter- 

 rupted depression ; scutellum fulvous ; elytra longitudinally depressed below 

 the shoulders, the lateral margins widened towards the middle, the surface 

 very closely and strongly punctured, black, shining ; legs entirely black, all 

 the tibiae armed with a spine. 



Hab. South Africa. 



Of this species, which may be known from I. melanoptera, 

 Thoms., and some other nearly similarly coloured species, by 

 the strong punctuation of the elytra, I possess a single appa- 

 rently female specimen, without exact locality, from South 

 Africa. 



Idacantha (Hyperacantha) bidentata, Fabr. 

 As already remarked above, Allard has placed this insect in 

 Aulacopliora, while Harold places it in Idacantha. Baly, in his 

 remarks in the * Entomological Transactions ' for 1890, regarding 

 this, says that, on account of the appendiculate claws, I. biden- 

 tata must find its place in Hyperacantha; but this statement is 

 again misleading, since the appendiculate claws are just the 

 characteristic structure of Idacantha : the insect can only be 

 rightly placed in Hyperantha if the anterior tibiae are unarmed, in 

 connection with the appendiculate claws. As I. bidentata is the 

 oldest described species, and must be looked upon as the type, it 

 follows that if the anterior tibiae are unarmed in that species, all 

 species having the same structural character, and for which 

 Chapuis established his genus Hyperantha, must be transferred 

 to Idacantha, and Hyperacantha cannot stand, but must be con- 

 sidered a synonym.
