42 Mr. Waterhouse’s Descriptions of 
stout—especially the posterior pair—black, with an obscure 
bronze tint; the tibize and tarsi are black: the anterior tibize are 
broad, 8 lines long, strongly quadridentate externally, and with 
two small dentations near the base; the tibize of the middle and 
posterior legs are beset with numerous stout and sharply pointed 
spines—these are chiefly confined to the upper and outer surface ; 
the posterior tibiae are much dilated at the distal extremity, where 
there are four stout spines: the tarsi are about equal in length to 
the tibize from which they spring: the claws each present a double 
hook, The terminal segment of the abdomen is furnished with 
two conspicuous tufts of reddish hairs. 
The specimen from which the above description is taken is a 
female, and, as might be expected, does not present the peculiar 
character from which the Scarabeus longimanus received its 
name; its anterior tibiae and femora are, in fact, not more elon- 
gated than most other species of the section. In general appear- 
ance (the colouring excepted) the present insect so resembles the 
S. longimanus, that Mr. Melly, to whom it was shown, at once 
pronounced it the female of one of that group, and, upon a careful 
examination, I have found his opinion correct. The structure of 
the middle and posterior pairs of legs is the same, and it moreover 
possesses the doubly hooked claw (or it may be described as having 
a hooked spine on the under side of the claw), which is one of 
the characters upon which M. Laporte founds his genus Parropus, 
the type of which is the Scarabeus longimanus.
