I consider this scarce and interesting insect to form a passage be- 

 tween the Lebiid^: and Pericalidje, but am doubtful to which of 

 these two tribes to refer it as, although it partakes of the character- 

 istics of either, it is at the same time distinct from both. Distin- 

 guished in several respects, its most extraordinary character lies in 

 the curious shape of the mentum. This is, however, easily describ- 

 ed as large, of the shape of a horseshoe with a long, thin, very point- 

 ed tooth in the middle, the apical half of the sides (lobes) being at 

 the same time gently dilated, the apex itself being obliquely cut 

 away from the outer towards the inner side (the inner angle being 

 the most advanced) and slightly dentated at the edge thus formed. 

 Or it may also be described as a fork with the outer teeth some- 

 what enlarged, truncated at the apex and so forth. As far as I 

 know, this variation from the usual form of the mentum is re- 

 peated in no other Carabideous insect. The other parts of the 

 mouth have not much to distinguish them with the exception, how- 

 ever of the labrum which attains a very extraordinary degree of de- 

 velopment occupying rather more than one-third of the tvhole head, 

 although the latter itself is large and heavy. It is of a suborbicular 

 shape, very slightly produced in front into an obtuse angle, is vault- 

 ed, covers the mandibles, has two longitudinal impressions at the 

 sides of the base and is highly polished. The head has two im- 

 pressions in front of the eyes, is densely punctured and thinly 

 pubescent, it is strongly but gradually contracted behind the eyes
