Tribe XLIV.— Peleciini. 

 AntennsB moderately long, filiform, arising under a distinct frontal ridge, first 

 joint stout, a little longer than the others, 2—11 subequal, the first three joints 

 glabrous. - Head quadrangular, suddenly narrowed at a distance behind the eyes 

 to a neck which broadens in a semiglobular manner, front with one supra-orbital 

 seta and with a cicatrix behind the eye, clypeus moderately prolonged and without 

 lateral setigerous punctures. Eyes small, oval, and very distant from the buccal 

 opening. Labrum transverse, concave and emarginate, with six setse, the outer 

 one on each side vertical and longer, functionally replacing the clypeal seta. 

 Mandibles stout, prominent, decurved, arcuate, acute at tip, without external 

 setigei-ous puncture. Maxillae slender not hooked at tip, ciliate within, outer lobe 

 slender, biarticulate, the palpi stout, the outer joints setose, the terminal joint 

 securiform or oval-truncate. Mentum transverse, the lateral lobes obtuse at tip, 

 emarginate with an acute tooth as long as the lateral lobes. Ligula moderately 

 prominent, arcuate or truncate in front and bisetose, the paraglossse adherent at 

 the sides, free and slender at their tips and ciliate within, palpi stout, terminal 

 joint longer tlian the second, securiform or oval-truncate, second joint bisetose 

 in front. Thorax margined at the sides and with two setigerous punctures, the 

 posterior distant from the hind angles. Body not pedunculate, scutellum more 

 or less distinct. Elytra more or less distinctly margined at base, the humeri 

 prominent, fifth interval at base often subcarinate, sides narrowly inflexed, margin 

 slightly interrupted posteriorly but Avith a well marked internal carina, disc 

 without dorsal punctures. Presternum not prolonged at tip. Mesosternum obtuse 

 in front, the epimera very narrow. Metasterual epimera very indistinctly sepa- 

 rated, the posterior coxse separated rather widely, the first ventral segment visible 

 at middle. Legs moderately robust, the tibiae not ciliate or spinulose externally, 

 the anterior moderately wide, deeply emarginate internally, the inner spur remote 

 from apex but situated posteriorly. Tarsi not slender, the fourth emarginate 

 or bilobed. 



The tarsi of the front and middle legs have four joints dilated and densely 

 pubescent beneath in ))oth sexes, tlie males have sometimes the middle tibiae 

 arcuate. 



This tribe contains but one genus Pelecium Kby., (Eripus BcJ., 

 Augasmosomus Chd.'), with the species extending froui Mexico to Brazil, 

 all of which are of moderate size, and some {ci/anipes Kby.), with the 

 elytra recalling the sculpture of our DJrs^lua Init more convex. No 

 member of this tribe has been found in our fauna. 



Kirby placed the genus between Cj/chrus and Fandgseua and is fol- 

 lowed by others. Dejean while placing it among the Harpalini remarks 

 that it does not well fit there. Lacordaire following Chaudoir places 

 it in a group Stomides which Schauni justly says has no fundamental 

 character and which is in fact the most heterogeneous tribe in Lacordaire's 

 Carabidaj. Schaum, however, while indicating that it must form a sepa- 

 rate group, (Berl. Zeitsch. 1860, pp. 128 and l'J3), writes around the 

 subject leaving us as much in doubt as to its position as before. 



I do not believe there can be much doubt of the relationship of the 

 Peleciini with the Broscini through Baripus and Zacofus.
