unite the Goliathites with the Leucocelites. It is worthy of note 

 that in these two genera, and also in Pscudoprotcetia, the shape of the 

 basal joint of the hind tarsi is that of the Goliathites, but I have 

 already explained that I subordinate this character to the mode of 

 sculpture of the elytra, in spite of the somewhat robust faciesof the 

 species belonging to the above-named genera ; in the other genera 

 this basal joint is rounded at apex, but in Homalothyrea, the whole 

 facies and colouration of which is that of Leucocelis, this joint is 

 elongated and dentiform in the 2 , but short and only acute in the $ . 

 The sexual differences are not easily distinguishable, but in Mauso- 

 leopsis the claws of the anterior tarsi of the S , and in some species 

 of the same genus the hind tibiae, differ in shape from those of 

 the 5 . In Pseudoprotcetia the shape of the clypeus is slightly 

 different in the two sexes. 



Key to the Genera. 



A 2 . Basal joint of hind tarsi sharply angular or spinose outwardly 

 in both sexes. 



B 2 . Basal part of prothorax covering the greatest part of the 

 scutellum. 



C. Inner costa of elytra not obliterated in the posterior 

 part. 



a-. Maxillee toothless, and provided with a long pencil 

 of hairs. 



Body somewhat massive, pubescent underneath and 



sometimes above ; sternal process bluntly knobby Clinteroide*. 



B 1 . Basal part of prothorax normal, plane, arcuate above 

 the scutellum. 



a 1 . Maxilla? dentate on the upper side, which is also 

 penicillate with hairs. 



Body depressed, attenuate behind, punctures on the 

 elytra strongly cicatricose, sternal process constricted 

 between the coxse, transversely arcuate Tephrcea, 



Body massive, not much attenuated behind, upper 

 maxillary lobe strongly bi-dentate, sternal process 

 constricted, transversely arcuate, inner costa of elytra 

 transversely coalescing with the outer in the centre. . Pseudoprot<rti«. 



A 1 . Basal joint of hind tarsi not angular or spinose outwardly. 



B 2 . Basal part of the prothorax normal, sides of scutellum 

 deeply sunk. 



C 2 . Sternal process not marginate in front. 



D^. Inner costa of elytra obliterated in the anterior 

 part, post-scutellary region strongly depressed.
