394 Coleopterological Notices. 



Eres emarginate anteriorly, coarsely faceted, the facets separated by coarse, 

 and very strongly elevated carinas ; epipleurae imperfect, wide near the 

 base, very narrow near the apex and completely obsolete in the middle. 



^reiclieniini 

 Anterior tibiae very short, broadly triangular, not dentate and devoid of denti- 

 form process. 



Eyes well developed, not emarginate, the lenses separated by narrow, acute 

 and very strongly elevated carinse ; epipleurte completely obsolete through- 

 out ..CiieiuepSatia 



Eyes obsolete, represented by a small deep fovea on the subacute lateral 

 margin near the base, the bottom of the fovea apparently sensitive ; epi- 

 pleurae very faintly defined near the base only Alaudes 



By this arrangement the Pimeliini and Pedinini are entirely, and 

 the Eiilabini and Opatruniini chiefly, characteristic of the eastern 

 hemisphere, while the Upini and Tenebrionini are most numerous 

 in the western world. The Amphidorini are peculiar to western 

 J^orth and South America, while the Blaptini, Scaurini and Leieh- 

 enini are almost equally represented in the eastern and western 

 continents. 



ELEODES Esch. 



The genera of Blaptini are closely allied and, in general, mutually 

 distinguishable only by some single structural difference ; even this 

 is not always of definite and unequivocal value. The P^uropean 

 Prosodes, for example, is extremely close to Eleodes and differs, as 

 far as can be clearly perceived, only in the strong compression of 

 the four posterior tarsi. Gnaptor differs onh- in the complete ex- 

 tinction of one of the spurs of the anterior tibiae and the abnormal 

 development of the remaining one, a character which the casual 

 study of our s])ccies of Eleodes will tend to prove of doubtful im- 

 portance. I think, also, that it will be found difficult to state any 

 absolutel}' constant diflerence between the females of Blaps and 

 Eleodes. It is true that the mentura varies, but in this respect the 

 difference in the form of this organ among the various species of 

 Eleodes, is vastly greater than that between Blaps mortisaga and 

 Eleodes snluralis. The form of the mentum is in fact of very little 

 value in this tribe, or indeed in many others of the Tenebrionidie, 

 as an examination of the species of Eulabis or the sexes of Uloma 

 will amply demonstrate. 



Before describing several distinct forms of Eleodes which have
