species. From nearly similarly coloured species of Hi/prracant/ia tlie shape of the 

 black bands and the black margin at the apex of the elytra will separate it ; if the 

 black colour is taken for that uf the ground, the elytra have a fulvous transverse 

 band at the middle, the anterior margin of which is deejjly concave, and a round 

 fulvous spot at the apex, the black breast and legs is another distinctive character 

 of the species. 



Hab. Natal and Transvaal (coll. Jacoby). 



Hyperacantha (Galerucella) melanoptera Thorns. 



This species, wrongly jilaced by Tlnimson in Gali'nicdla, must be placed in 

 Hyperacantha on account of having appendiculate claws. The male insect, besides 

 having an elytral tubercle placed close to the suture near the apex, has the last 

 nlxlominal segment trilobate, the median lobe of which is broader than long, 

 flattened and longer than the lateral more rounded lobes ; the species has entirely 

 black elytra ; in the female the ventral terminal segment is very slightly produced 

 at the middle, and has a more or less distinct emargination at the apex. 



Specimens from Kuilu, Caiacroons, Sierra Leone, Gaboon. In some specimens 

 the breast and legs are entirely black. 



Hyperacantha insignipeanis Thoms. 

 Like the preceding species, the present one must be placed in Hyperacantha. 

 Thomson describes the type from specimens having a basal and an apical broad 

 black elytral band, both being connected at the lateral margin. I have however 

 seen many specimens of a variety which I cannot separate in any other way from 

 the type, in which the posterior band is very narrow leaving the ajiex of the elytra 

 broadly fulvous ; the male characters agree entirely with those of the preceding 

 species, both having the sutural elytral tubercles and a strongly raised longitudinal 

 costa at the sides, the female differs however from that of H. melanoptera in not 

 having the triangular emargination of the ventral last segment but a very slightly 

 rounded and produced medial lobe ; sometimes the black bands of the elytra 

 occuj)y the greater part of the surface, leaving only a small fulvous patch at the 

 middle of each elytron. The species inhabits the same localities as H. melanoptera. 



Hyperacantha (Galerucella) flavonigra Thoms. 



The coloration of this species is almost identical with that of the j)receding, 

 but the black basal band of tlie elytra leaves generally the extreme basal margin of 

 the fulvous ground colour and the posterior patch is more oval, antl does not extend 

 to the apex ; a better character of distinction is however found in the want of the 

 elytral tubercles in the male, and in the shape of the median lobe of the last ventral 

 segment, which is less transverse than in the other species and has a slight 

 triangular emargination at the apex, in some specimens the elytra are almost 

 entirely black, leaving just a trace of fulvous at the base, across the middle and at 

 the apex. 



Dr. F. Karsch has described and figured in the Berlin. Entom. Zeitsch. several 

 species of Diacantha (^Hyperacantlta), which seem to me to belong to either of the 

 above-named species which Dr. Karsch probably did not know, as he does not 

 compare his species with either of them. I refer in particular here to D. nigritarsis 

 Karsch, D.Jlnripes Karsch, and ]>. interrupta, Karsch.
