CARABIDAE. 15 



Tribe IX.— PROMECOGXATHI]Vl. 



Antennae feebly geniculate, arising under a slight frontal 

 margin ; first four joints glabrous, tlie first much larger and 

 stouter than the others, 5-11 slightly compressed and finely 

 pubescent. Eyes small, slightly oval and distant from the buccal 

 opening. Head with two supra-orbital setee, neck slightly bi-oadcr 

 behind the eyes. Labrnni short, bisinuate. Mandibles elongate, 

 arcuate and acute at tip and decussating, not toothed within. 

 Mentum short, broad, broadly emarginate and with a broad short 

 tooth, epilobes narrow but distinct, mental sutul'e distinct. Gula 

 deeply transverse!}' impressed, so that the mentum is inserted at 

 a right angle to the peduncle. Ligula moderately prominent, 

 narrower and free at tip, truncate, with two sette ; paraglossae 

 long, rather slender and ciliate within at the tij). ]V[axilhe with 

 inner lobe slender and long, obtuse at tip, densely ciliate within, 

 outer lobe biarticulate, the terminal joint much shorter. Maxillary 

 palpi moderately long, the second joint equal to the next two 

 together, terminal joint broader at tip, truncate and twice the 

 length of the third. Labial palpi with the last two joints about 

 equal in length, the terminal broader at tip and truncate, the 

 preceding bisetose' in front. Thorax narrowed at base, sides 

 narrowly inflexed, lateral margin distinct, a setigerous puncture 

 near the hind angle and three at the side in front. Body pedun- 

 culate, scutellum invisible. Elytra not margined at base, lateral 

 margin distinct and entire, sides narrowly inflexed. Anterior 

 coxal cavities closed behind, prosternum not prolonged, mesoster- 

 nuni declivous. Metasternnl epimera indistinct. Femora stout, 

 the anterior more strongly clavate. Anterior tibiae gradually 

 broader to tip, smooth externally, deeply emarginate internally, 

 the inner spur remote from the tip. Posterior coxte separated 

 by a triangular process of the abdomen which meets the meta- 

 sternum. Tarsi moderate, the posterior longer, first joint moder- 

 ately long, fourth slightly emarginate. Tarsi similar in the sexes. 



The present genus was associated by Chaudoir with Sl(>niii<, 

 with which it has no (•hai'acter in common, except the elongate 

 mandibles; Lacordaire has adopted the group Stomides as estab-
