of head and ]irotli()rnx is finely coriaccously plicate. In 

 chain, the [jlieations are very Taint, snh-ohsolcte, and, pe.f 

 coiitfd, the snbhasal depressions and foveie arc deeper. The 

 intervals ol" the elytra ai'c in cliam more cariuate, the strife 

 narrower, deeper, and distinctly [)unet;ite. There is a com- 

 plete absence of metallism in all specimens of C. cham that 

 have eome under my observation. I have examples of this 

 s|)e(;ies from districts as wide apart as the ncij^hbourhood of 

 Durban and Fi'cre, i.e., 1(51 miles, and with a dilYercnee in 

 akitnde of 3500 feet, yet they show no variation from type. 

 'I'he altitnde of llardini^ is ai)proxiniately the same as that 

 of Frere, but considerably more than 1^ degrees to the 

 southward, it must be confessed, however, that the modifi- 

 cations of structure and sculpture are only slight, atul 

 further knowledge may prove later clarksoni to be only a 

 ■local raC(.> or subspecies of Chaudoir^s insect. 



Speciineus of C. chirksoui show considerable variation in 

 the extent of metallic green underlying the bronze. Some 

 appear to be nearly wholly green in strong lights and others 

 under similar conditions show only faint traces of it. It is 

 always more or less noticeable about the margins and in 

 the interstices of the elytra. I submitted one or more 

 examples to Dr. Peringuey, in the year 1899, who then 

 pronounced it a new species and gave it the MSS. nan)e 

 hurkeri, but no published description nor further mention 

 of it has since reached me. 



All the examples so far known to me were collected by 

 Mr. Clarkson on his farm near Harding, Alfred Countv, 

 Natal, who informed me that he found them harbouring 

 under dry cow-dung. 



Soutii-African Chljenii with a Cazathus-like Facies. 



Of this very distinctive section of a huge genus Dr. 

 IVringuey, in his 'Descriptive Catalogue,^ 1896, pp. 517-519, 

 has described or referred to six species, five of which are 

 represented in the Durban Museum Collection, namelv, 

 Ch/tenius Jichrons, Wicd. ; C. pkeus, Chd. ; C. trapezico/fis, 

 Clid. ; C. iiafale7isift, did. ; C. erythrocyiemis, Chd. — leaving 

 only C. oodioides, did., unaccounted for. 



C. cham, Chd., and C. clarksoni, mihi, described above, 

 I have purposely omitted, as 1 consider they belong to a 

 class apart. Peringuey also described a species under the 

 designation aculeatns, but this he has since recognised is not 

 Chheniun at all, but a Pterostichid of an, at present, undeter- 

 mined genus.
