Rah. Malvern, Natal {C. Barlccr). 



I received four specimens from Mr. Barker. 



Galerucin.e. 



Genus Diacantha, Chev. 



I cannot agree with Weise in his definition of this and 

 the alhed genera (Deutsche Ent. Zeitscb. 1901, p. 274). 

 He has evidently overlooked the type D. hispinosa, Oliv. 

 Chevrolat in his diagnosis of the genus in D'Orbigny, 

 Diet. Univ. d'Hist. Naturelle, p. 718, iv, quotes 12 species 

 mentioned by Dejean in his catalogue. These are — I). 

 picca, Fab. ; spinosa, Oliv. ; (hisp)inosa) /estiva, Dahn. ; 

 iinifasciafa, Oliv. ; 11 pinidafa, Dej. ; Drcgci (6 pustulata 

 = tricincta, Chev.); fnscitarsis, gloriosa, tcstudinaria, Dej. ; 

 U7iip)unctata, Chev., et generosa, Dej. 



Of all these only D. Mspnnosa and D. dregei belong to 

 Diacantha as defined by Chapuis, and the first named 

 must undoubtedly be taken for the type. In this species 

 the claws arc hi/d and the ma'e has two elytral tubercles 

 at the ba?c ; most of the other species named above bclmig 

 to entirely different genera, thus j;t«« is the genus ' 

 Stcnop)latys, Baly, \1 piinctata, Dej., is ixn. yiulacop)hora, aic. 

 Harold gives D. hidcntata, Fab., as the type of the genus 

 Diacantlia, but as this is not one of the species mentioned 

 either by Chevrolat or Dejean, it cannot be looked upon 

 as the type. Chapuis was therefore perfectly right when 

 he established the genus Hypcracanthct, in which the 

 claws are appendiculate, and his genus must be accepted. 

 Weise has not said which species he looks uj)on as the 

 type, and has not mentioned the only true Diacantha. 

 of Chevrolat's list D. hispinosct. A typical specimen of 

 this species is contained in the British Museum, and I am 

 indebted to Mr. Gahan for his examination of the specini:. n 

 and the other details given above concerning the genus. 



Hyperacantha Intuhcrculcda, Fab. 



According to Mr. Gahan the specimen contained in the 

 British Museum is certainly the typical hituhercukda, Fab., 

 and named so by Dejean himself and also by Chevrolat. 

 Weise expresses a doubt that I had this species before 

 me when I remarked on it in Novitates, 1894, and gives 

 the last abdominal segment of the ^ with three deep
