I tWnk it will therefore be advisable to consider tbem as forming a 

 small separate group, to be placed near the Aphodiides. Though the 

 structure of the hind-body appears to be so like that of Tro^, in their 

 other characters these insects do not show any considerable approach 

 to the Trogides. The genus Eremazus of Mulsant belongs, I have 

 little doubt, to this group, which may be called Tolisides, if it be con- 

 sidered neccssaiy to give it a special name. Though Mulsant does 

 not speak of the structure of the hind-body, he placed his genus in the 

 Trogides. Lacordaire, to whom this genus of Mulsant was unknown, 

 placed it with doubt in the Ajjhodiidcs, calling attention, however, to 

 Mulsant's silence as to the structure of the hind-body. It is also 

 worth while noticing that Pairmaire has described (Ann. Soc. Ent. Er., 

 1870, p. 374) an insect under the name of uSSgialia Marmottani, which 

 I feel pretty certain is a member of the group Tolisides. Pairmaire 

 tells us that he did not dare to take oif its card the single example 

 known of his 2E. Marmottani ; but the characters he mentions to dis- 

 tinguish it, viz., the invisible eyes, the unstriated elytra, and the Tra- 

 chyscelid facies, leave no doubt in my mind that it is a member of the 

 group here established, ^gialia Marmottani was found at Biskra in 

 Algeria ; and it is highly probable that it is synonymous with Erema- 

 zus tmistriatus, Muls. 



MiLLiKGENiA, n. gen. 



AntenncE small, ciglit-jointecl, 1st joint stout, oval (much naiTower just above 

 the base than at the extreinity), its length not quite twice its width, 2ncl joint stout, 

 quite twice as broad as the following joints, joints 3, 4 and 5 small, the 5tli shorter 

 and scarcely broader than the 4th, closely applied to and not very distinct from the 

 base of the 6th joint, joints 6 — 8 forming a comparatively large oval club, the sutures 

 of wliich arc transverse. 



Mandibles short but very thick, outwardly rounded, the inner margin forming 

 three or four stout teeth. 



MaxillcB with both lobes distinct, the inner one small, apparently homy, and 

 divided into three or four short finger-like lobes. The upper lobe membninous, 

 armed on the inner side vrith six or seven pointed spinula?, furnished outwardly with 

 a long, fine pubescence. Maxillary palpi long, four-jointed, the tei-minal joint elongate- 

 oval, longer than the two preceding joints together. 



Mentum rounded at the extremity and emarginatc in the middle, Ugula entirely 

 concealed ; labial palpi three-jointed, 1st joint slender, cylindrie, moderately long, 

 2nd joint sub-triangular, about as long as broad, 3rd joint oval (or rather pear-shaped), 

 longer than the 2nd joint. 



Labrum transverse, the front margin slightly emarginate in the middle, but 

 covered with a dense pubescence, which projects much beyond the labrum and pre- 

 vents i(s form being seen. _
