and is here figured ; the long antennal-clubs of the male, as well as the 
longer and narrower thoracic spines, distinguish it from the preceding 
genus. A. Parrii is from the Himalayah. Trigonocephalus, Hope, is 
represented as a peculiar genus, with four species ; of these plates are 
given of Tr. nepalensis (Hardwichii), DeUssertii, and a new one, 
Tr. Saundersii, from the East Indies; the fourth, Tr. Cantori, Hope, 
according to Westwood, does not ditfer from the first. Under the 
name Heterorhina, he comprehends those of which the males have 
not the fore-legs remarkably long. It is principally formed from 
Onathocera and Dicheros, Gory. The different species, even those 
nearest allied, deviate in the characteristics of the sex and the form of 
the maxillary lobes, the latter vary also in different individuals of the 
same species, and even in one and the same individual ; there belong 
to it of Asiatic species — for the genus is also common in Africa — •

species from the Philippines ; decora (Dick, dec.. Gory) ; Petelii, Buq. ; 
which last scarcely differs from the preceding. These twenty-three 
species are, with few exceptions, figured with dissections. 
Westwood has illustrated the Goliatkidce of Africa in a similar 
manner. At the top stand Hypselogenia and Goliatkus with the 
three known species, G. giganteus, Lam., which he examined in 
the Glasgow collection ; Drurii, Westw. ($ regius, Kl.) ; and Cacicus 
(9 princeps, Hope). Of Mecynorkina, Hope; M. Polyphemus 9, and 
torquata ^ and 9> are represented in excellent plates. Under Cerato- 
rhina the author comprehends Dicronorkina, Hope; and Eudicella, 
White ; the group Dicronorkina is composed of micans, Drury, 
which the author holds to be different from that found at Senegal, and 
to which, on this account, he gives a new name, cavifrons ; splendens, 
MacLeay ; and both sexes of a splendid new species, C. derbyana, 
Melly, from the interior of South Africa, are very beautifully figured. 
The second group, Eudicella, White, contains Daphnis, Buq. ; Smithii, 
MacLeay; Morgani, Wh. ; frontalis, Westw.; the two latter are 
figured ; Grallii, Buq. ; and one new species, C. (Eud.) ignita, Westw., 
from the Gold Coast. The third group, Cheirolasia, Westw., is a new 
form, where the anterior tibiae of the male are unarmed either outwardly 
or inwardly ; but on the fore-legs, on the inside, the tip of the thigh,
