ILLUSTRATIONS OP FOUR SPECIES OF THE GENUS CHIROSCELTS. 
CHIROSCELIS, Lamarck, Ann. d, Mas. iir., p. 260. 
This genus was established for the reception of an insect respect¬ 
ing whose native country there is some doubt, Lamarck stating, 
“ Ce col^optere habite vraisemblablement dans la XouvelleHollande, 
car il se trouvait parmi ceux de cette contree que le Capitaine 
Baudin a envoyes par le vaisseau le Naturahsteand Latreille 
states of it, “Habitat in Australasia; insula Sta. Maria, Dom, Peron, 
Lesueur,’’ adding (Gen. Cr. ii. 144), “ Speciem alteram priori fere 
simileni at paulo minorem et maculis abdominalibus nulHs ex Africa 
attulit Peron.” Lamarck’s insect is stated by him to have been “un 
peu plus de 4 centimetres (im pouce et demi) de longueur,” and his 
figure “ de la grandeur naturelle,” represents an insect 20 lines long. 
On this account, and especially as a species of the genus has now 
been detected in the south-east part of Africa, it is probable that 
Lamarck’s species is distinct from the following:— 
CHIROSCELIS DIGITATA, Fair. 
(Plate 87, fig. 1. ^.) 
C. nigra nitida elytris parallelis, tibiis posticis inermibus, maculis abdominalibus subovatis.

Ample details of the structure of this species are given in my 
paper on the African Tenebrionidse, published in the third volume 
of the Transactions of the Zoological Society; in addition to 
which, it is to be observed that a dissection of both kinds of 
individuals of this species—namely, those possessing and those 
destitute of the luteous sericeous patches on the underside of the 
second segment of the abdomen, has proved that the suggestions 
which I made in my Introduction to the Modern Classification 
of Insects, vol. i. p. 320, 322, as to the sexual distinctions of these 
individuals (founded on their analogy with other Melasomata) 
were correct, the specimens destitute of the patches being males; 
one of these individuals is represented in fig. 1; fig. 1 being the 
figure of the underside of the abdomen ; and fig. 1 the male sexual
