256 DESCRIPTION OF SCARAB.EI. 



Caput parvum inerme, prothorace fere reconditum : mandibulse 

 maxillaeque haud clypeum attingentes reconditse, mihi invisse : 

 maxipalpi (quasi) 3-articulati ; articulo l mo . obconico ; 2 do . 

 vix crassiori, liquido breviori ; 3 tio . elongato, incrassato subtrun- 

 cato : labipalpi (quasi) 3-articulati ; articulo l mo . 2 doc i ue . obconicis, 

 3 tio . elongato apice rotundato : pedes longi ; tibiis angulatis, 

 spinis validis armatis : protibiis longissimis, incurvatis, dentatis, 

 unguiculis omnibus duobus apicibus, acutis, valde curvatis, subse- 

 qualibus ; plantula inter unguiculos brevis, apice bisetosa. Sca- 

 rabaearum neque antennae nee profecto prothorax, distributionis 

 discrepantiae exhibent. An. Euchirus celeberrimi Kirbii? 



Sp. 1. Propo. Arbaces. Brunneus glaber ; prothorax corpore 

 vix latior, valde convexus, biennis, rugose punctatus, lateribus 

 subserratis, angidis posticis valde, semicirculariter emarginatis, 

 subtus pilis aureis vestitus; protibice subtus pilis aureis vestitw.

This beautiful insect nearly corresponds in structure with the 

 Scarabwus longimamis of Linnseus ; a sketch of the anatomy of 

 which has been obligingly handed me by Mr. Westwood ; it 

 is, however, I am led to believe, a perfectly distinct species. 

 It is said to have been taken at Smyrna, but appears to me 

 rather more of a Brazilian than European or Asiatic form. 

 The only specimen I have seen is in the rich cabinet of Mr. 

 Hanson. 



Genus. — Scarabwus. Linncms. 



I know of no group in Entomology that calls so loudly for 

 further generic division as that immense mass known by the 

 common appellation of Scarabams, or, according to some 

 authors, Dynastes ; and, in Fabricius, described under the 

 name of Geotrupcs. The separation of an isolated species or 

 two as the proposed genus Propomacrus for the reception of 

 Arbaces, and perhaps longimamis, is altogether insufficient, and 

 is a task from which I would most willingly have shrunk. 



Scarabaeus Crcesus. Tot us testaceus ; pedibus villosis. Tab. xiv. 

 Icon. 2. 



There are several examples of this fine insect in the London 

 cabinets, all of them, I believe, imported from Jamaica by Mr.
