serrations, which are so minute as to require very careful observation for their detection. 
In the female this plate is more deeply emarginate and destitute of serration. 
This is a very distinct species, and has the mesosternal process very slender, so that 
the middle coxe are more approximate than usual, the carina extending, however, 
quite to its extremity. Four individuals from Panama and one from Guatemala have 
been taken. 
13. Aleochara miradoris. 
Fulvo-testacea, antennarum basi pedibusque testaceis, abdomine piceo-rufo, segmentis sexto et septimo rufis ; 
antennis subgracilibus, articulis 5°-10™ leviter transversis; abdomine apicem versus attenuato, subsparsim 
vix fortiter punctato, nitido. 
Long. 6 millim. 
Hab. Mexico, Mirador (f6ge). 
Antenne slightly thickened externally, third joint a little longer than the second, 
fourth about as long as broad, fifth to tenth each evidently broader than long; 
terminal joint rather elongate, a little longer than the two preceding together. Head 
rather small and short, obsoletely punctate. Thorax rather strongly transverse, a good 
deal narrowed in front, quite finely, moderately closely punctate, very distinctly and 
closely pubescent. Elytra about as long as the thorax, densely and rather finely 
punctate and densely pubescent. Hind body shining, and only very sparingly pubes- 
cent; the segments with a moderately coarse and not close punctuation. 
Only a single individual of this species has been found ; it is a male, and has the hind 
margin of the seventh dorsal plate very slightly emarginate, and furnished with ten or 
twelve fine but distinct serrations. The mesosternal lamina is very slender at the 
extremity; but its carina is entire. 
14. Aleochara salleei. 
Subparallela, nigra, opaca, dense punctata, antennarum basi, palpis pedibusque fuscis; antennis crassiusculis, 
articulis 6°-10™ transversis ; capite fortiter, thorace elytris abdomineque sat subtiliter dense punctatis, 
hujus segmentis 2°-5™ summa basi fortiter, quasi rugulose punctatis. 
Long. 4-5} millim. 
Hab. Mexico, Guanajuato (Boucard, coll. Sallé). 
Second and third jomts of antennee about equal in length, joints six to ten rather 
strongly transverse, terminal joint not elongate, basal joint or two infuscate red. Palpi 
obscure red. Head coarsely and rather closely punctate. ‘Thorax rather strongly 
transverse, densely and rather finely punctate. Elytra about as long as the thorax, 
very densely punctate. Hind body very densely punctate, at the base of each of the 
second to fifth segments there is some deeper and coarser confluent punctuation. 
Legs sordid red. 
Of this species I have seen two badly preserved individuals; they have the hind
