present. Where the scape attains its typical length it is usually 

 more or less curved near the base. It is ditlicult in many of the 

 genera to say how many joints are truly pubescent, as the hairs 

 extend nearly to the base of the first joint. 



The head assumes three forms: the first is that typified by 

 Galerita, in which the head is elongate-oval, considerably pro- 

 longed behind the eyes, then constricted to a very narrow neck 

 which dilates to a semiglol)ular condyle; the second is the Zu- 

 phium t^^pe, where there is a moderate prolongation behind the 

 eye, and then very suddenly constricted to a narrow neck which 

 is cylindrical ; while in Drijpta the constriction is close to the 

 eyes, not abrupt, and the neck rather stout and cylindrical. The 

 latter genus is further remarkable in having the setee of the 

 clypeus entirely wanting, their function being replaced by those 

 of the outer side of the labrum, which acquire an unusual devel- 

 opment; a similar character has been observed in Pelecium. 



Our genera are not numerous, and may be known by the cha- 

 racters of the following table ; — 



Neck very narrow. 



H(;acl prolonged behind the eyes, neck inserted in thorax by a semiglo- 

 bular condyle. Clypeus with two setigerons punctures each side. 



Galerita. 

 Head triangular, scarcely prolonged behind the eyes, veiy suddenly 

 constricted to a narrow cylindrical neck. Clypeus with but one seti- 

 gerons puncture on each side with a long seta. Zuphium. 

 Neck stout, head very little constricted. 



Thorax truncate at base, antenn;e with third joint shorter tlian the 



fourth. Diaphorus. 



Thorax subpedunculate at base, antennae with joints 2-4 nearly 



equal. Thalpius. 



These genera are represented on both sides of the continent. 



Tribe XXV.— EGIXI. 



Antennae moderate in length, slightly thicker externally, aris- 

 ing under a feeble frontal ridge, the four basal joints glabrous ; 

 that is, they are somewhat hairy, but not densely j)unctured and 

 finely pubescent as the following joints ; the basal joint moderately 

 stout, but not equal in length to the two following joints together. 

 Head oval, rather strongly constricted at a distance behind the 

 eyes to a neck, with two supra-orbital setae. Eyes oval, in tlu^
