ON THE CETONIIDiE OF SOUTH AFRICA. 
Cetonia hispida of Olivier. There is no affinity to the genus Syrichtus whatever, or to any of the 
Dynastidai. The relation between them is one of analogy. 
79. The fourth section is from the Cape, and is, like the fifth, typical of Ischnostoma. I have 
called it Heteboclitjs, because I suspect the insect described by M. Gory as “ Ischnostoma , 
heteroclyta” will be found to belong to it. A species of this section has been brought home by 
Dr. Smith ; but, like that of the Museum of Natural History at Paris, is in sad preservation. 
I must here observe, that M. Gory’s figure of Ischnostoma albomaculata is singularly incorrect, 
and therefore I am led to infer that the figure of I. heteroclita is incorrect also ; the more so 
as M. Gory’s description of the heads of these two insects does not agree with his figures. 
Sp. 24. (Cetoninus) Ischnostoma spatulipes, n. s. 
Descii. Ischnostoma atronitida, capitc porrccto clypeo quadrato margine reflexo apice emarginato 
lobis rotundatis, corpore valde convexo, thorace subsemicirculari punctato marginato, scutello 
magno, elytris sub-rugosulis apice subtruncatis, metasterno brevissimo truncate, tibiis anticis 
extus tridentatis, calcaribus posticis spatulifonnibus. 
Long. 10 lines. 
Note. This species may be the C. corclata of Fabricius. It has an indentation in the centre of the 
thorax, being the first vestige of the deep one that exists in Ischnostoma cornuta. 
80. The section Cuspidate is, like the last, singular for its trichioid form, but differs in the 
body being more depressed, and in the clypeus being of a very peculiar form, owing to its 
extreme length, and the sides of it being at the base deeply emarginate. The feet are also 
longer and less strong ; but both sections are remarkable for a long narrow labrum, which, 
however, is exceedingly minute in proportion to the size of the insect. 
Sp. 25. (Cetoninus) Ischnostoma pica, n. s. 
Descr. Ischnostoma atroviolacea velutina punctata, pilis nigris operta, thoracis vittis marginalibus 
elytrorumque vitta marginali humerum nec suturam mediam attingente albis, corpore 
infra atronitido, pygidio maculis duabus albis magnis, pedibus nigerrimis calcaribus posticis 
acutis. 
Long. 10 lines. 
Note. This species is very close to the Cetonia cuspidata of Fabricius, but there are no “puncta duo 
cinerea inter autennas,” and the whole of the margin of the thorax is not cinereous. Whether Ischnostoma 
pica be identical with the Melolontha albomarginata of Herbst, I know not ; but certainly it is very 
different from the Ischnostoma albomaculata of Gory, which is in my collection. But we now return to 
the section of Arcadece, which, as I said before, comes so close to the Cetonia hispida of Olivier. By 
this section we arrive at the 
Sub-genus 5. Cetonia, G. P. 
8 1 . This groupe is typical of the genus Cetoninus, and contains perhaps more species than all 
the rest of the family of Cetoniidce put together. Cetonia may be distinguished from 
Goliathus by the males not being horned, but having their clypeus of the same shape as that 
of the females. The anterior tibiae are also similar in the sexes, which distinguishes the sub- 
genus from Schizorhina, to which it closely approaches. From Ischnostoma, Cetonia may be 
separated by the sub-quadrate and emarginate mentum, and by the long penicillifoi m terminal 
process of the maxillae. In Cetonia the plantula between the ungues appears to be generally 
present, only it is apt to be rubbed off by use. The pseudonychia do not seem always to be
