side on the thorax. South America. Some travellers call it 

 the Mouche comue(\). 



S. dichotomus, Oliv., lb. XVII, 156. A fine maronne-brown; 

 a large bifurcated horn with cleft branches on the head; a second 

 one, smaller, curved and bifid at the end, on the thorax of the 

 male. The East Indies. 



S. longimanus, L. ; Oliv., lb. IV, 27. Fulvous-brown; head 

 and thorax destitute of horns and tubercles; the two anterior 

 legs more ihan half as long again as the body, and arcuated. 

 The East Indies. 



& punctatus; Oliv., lb., VIII, 70. Black; punctured; no ele- 

 vation in the shape of a horn in either sex; the epistoma truncated 

 anteriorly, and the angles of the section slightly raised in the 

 manner of teeth; two approximated tubercles on the middle of 

 the head(2). The only species in France. 



Phileurus, Lat. Geotrupes, Fab. 



The Phileuri only. differ from the Scarabsei in their mandibles, 

 which are straighter, destitute of sinus or teeth on the outer side, 

 and in their depressed body, the thorax of which is dilated and 

 rounded on the sides(3). 



Our second division contains Scarabaeides, closely allied to the 

 preceding in some respects, but also closely approximating to various 

 Melolonthse, and particularly to the Cetoniae, which they resemble 

 externally, but from which they differ in the arrangement of the 

 mouth; Fabricius and Olivier even arranged most of these Insects 

 with them. Their body is generally shorter, more rounded, smoother 

 than that of the Scarabsei, and decorated with brilliant colours. 

 The head and thorax are identical, and without any particular pro- 

 jection in both sexes. The anterior margin of the labrum is almost 

 always exposed or apparent. The maxillae are entirely scaly, as if 

 truncated at the extremity, and furnished on the inner side with five 



(11 This species is the type of the genus Dynasles, Kirby. The S. Actxon forms 

 another, that of Megasoma. See Lin. Trans., XIV. 



(2) The Geotrupes of Fabricius, with the exception of the precited species, 

 forming the genus Orydes, and of the following one. [We have several species 

 of this genus in the United States, among which should be particularly noticed 

 the large and splendid Sc. Tityus, the Antaeus, &c. Am. Ed.] 



(3) G- dydimus,vulgus, depressus, Fab. Certain undescribed species from Brazil 

 and Cayenne, somewhat analogous to Sinodendron, have a thicker body, and con- 

 nect the Phileuri with our Scarabaeides, or the Geotrupes of Fabricius, a genus 

 which has not been sufficiently studied with respect to the organization of the 

 parts of the mouth.
