paring- the types of C. cqffer Ffihr. and K^phen. castaneipennis 

 Boh., and there can be no question as to their specific identity. 



The form haridioides, desci'ibed hy Lacordaii'e as the type of his 

 genus C>/rto(r)rhrnus. ofters no structui-al difiei-ence whatever 

 fi-om the typical Natal forna of castaneipeniiis and difiers solely 

 in the hlack colour of its elytra, a character which caimot be hei-e 

 regai'ded as of specific value. The form nnda Ohevr., however, 

 fi-om Equatorial Africa jn-esents a striking sti-uctui'al difierence 

 from the Natal type in the complete, or almost complete, absence 

 of punctuation on the thoi'ax and the intei-vals of the elj'ti'a; 

 and at first sight it would appear to be a good and distinct species. 

 But an examination of Rhodesian examples shows this character 

 in an exactly intermediate condition, and as some specimens of 

 niida show distinct traces of punctuation it is only possible to 

 i-egard that foi-m as an exti-eme local race of the southern species. 

 T'lie occuri'ence of red elyti'a in the nuda fonn appeals to be 

 unusual, most specimens being of a rather intermediate piceous 

 brown colouring ; whereas in the south there is a sharp division 

 between the black and red foi-ms. In nuda the legs vary also 

 from piceous to red, Avhereas in South Afi-ica all the vaiieties 

 have black legs only. The punctuation of the thorax does not 

 diminish progressively northwards, for the most heavily punctured 

 specimens I have seen come from Beira ; and the Nyasaland 

 examples appear generally to be intei-mediate between those of 

 Rhodesia and Natal. 



The two genera Lioccdandra and Poli/aulax founded by Ohevrolat 

 must be sunk as synonyms of Cyrtorrliiims Lac.
