HARPALIN^E 49 



3 mm. in length, of a rather brilliant black color, native to the 

 southern provinces of Chile and of which he had only seen a single 

 example of undetermined sex. It was placed among the Feroniids 

 by Lacordaire. In view of the size of the body, the singular 

 structure of the antennae and the extreme southern and isolated 

 habitat, I think there can be but little doubt that we have been in 

 error in assigning to Polpochila our large Melanotus erro Lee. (capi- 

 tata Chd.), subsequently given the generic name Cratocara by 

 LeConte (Sm. Misc. Coll. 140, p. n, 1866) because of the previous 

 use of Melanotus. There can be no question concerning the close 

 relationship of Pogonodaptus Horn, with Cratocara, as stated by 

 Bates. It has no affinity whatever with Daptus. 



Tribe DAPTINI. 



The genera of this tribe, which abound and are greatly diversified 

 in America, but represented in the palaearctic fauna by the single 

 genus Daptus, may be distinguished among themselves as follows: 



Tarsi thick, the posterior rapidly tapering from base to apex, the anterior 

 clothed beneath in the male with confused erect squamiform hairs; 

 anterior tibiae with a ciliate terminal plate in both sexes, the tibial 

 surfaces not peculiarly modified Geopinus 



Tarsi slender, the posterior filiform, the anterior apparently never hairy 

 beneath, the anterior tibiae without lamelliform extension, though 

 peculiarly modified apically in Nothopus 2 



2 Anterior and middle tibiae thickened, densely, coarsely punctured and 

 spinulo-setulose over their posterior and anterior surfaces respec- 

 tively; body subpedunculate *Daptus 



Anterior and middle tibiae not specially modified on their lateral surfaces; 

 body not pedunculated 3 



3 Hind angles of the prothorax right or acute, frequently everted; 

 elytra oblong, the humeri distinct, the hind wings always well 

 developed 4 



Hind angles very obtuse but never at all broadly rounded; elytra oval, 

 with rounding humeri, the hind wings apparently vestigial; mentum 

 edentate 8 



4 Mentum edentate; ligula small and slender, much shorter than the 

 large and usually thickened ciliate paraglossae 5 



Mentum with a long and very acute tooth; ligula rather broader, not 

 evidently expanded at tip, exactly equal in length to the paraglossae. 7 



5 Body somewhat as in Daptus, narrower than in any of the following 

 genera, the head large, the prothorax cordate, the sides sinuate 

 before the right and very sharp basal angles; head without projec- 

 tions above the antennae, which are slender and filiform; elytra 

 rather short, wider than the prothorax, the base much wider than
