species, as it has the joints of the antenne just a little longer and the thoracic impres- 
sion rather slighter. As, however, it is a female, and these characters are very slight, 
no certain opinion can be formed about it. 
HOPLANDRIA. 
Hoplandria, Kraatz, Linn. Ent. xi. p. 4, t. 1. f. 6, t. 2. £. 14. 
This genus at present comprises ten described species from the New World (where 
it ranges from the southern portions of the United States to Brazil and to Chili) and 
a single species from Ceylon. I am acquainted, however, with numerous undescribed 
Brazilian Hoplandrie, and the genus will probably prove to occupy an important posi- 
tion among the more characteristic genera of Staphylinide of the tropics of the New 
World. Its characters and limits, however, are at present ambiguous. Kraatz (J. ¢.) 
defined it almost solely from the mouth-parts; and as regards these he seems to have 
overlooked one of its most important peculiarities, viz. that the terminal joints of the 
palpi are provided with a minute supplementary joint as in the genus Aleochara. 
Hoplandria, moreover, approximates to the latter genus in the shape and structure of 
the prothorax, and even (though to a less complete extent) in the considerably backward 
prolongation of the mesosternal process. The front tarsi, however, are only four-jointed ; 
and the genus is connected with the polymorphic Myrmedonia in a conspicuous manner 
by means of Platonica. It thus represents, in the tribe Myrmedoniates, the genus 
Aleochara of the Aleocharates. As no description has been given of the sternal struc- 
ture, I may add that the intermediate coxe are widely separated, and that the meso- 
sternal process is much produced between them, and joins the metasternal prolongation, 
so that the middle coxal cavities are completely margined ; the raised border of the 
mesosternal process is remarkably distinct, and is strongly elevated even at the apex, so 
that a very conspicuous transverse (but not straight) raised margin extends across the 
space separating the intermediate coxe. 
1. Hoplandria gemina. (Tab. VI. fig. 2, ¢.) 
Ferruginea, capite thoraceque, antennisque nigricantibus, his basi testacea, abdomine apicem versus piceo ; 
thorace valde transverso, eequali, haud impresso, cumque elytris parum crebre vix fortiter punctatis ; 
abdomine nitidulo, parum punctato. 
Mas elytris ad angulum suturalem processu acuminato, parum elevato ; abdominis segmento 2° ad latera utrin- 
que margine laterali libero, posterius breviter producto, segmento 3° carinulis duabus elevatis distantibus, 
segmento 6° in medio carinula elongata ad apicem magis elevata. 
Nota. Maris characteres sexuales supra notati interdum fere omnino desunt. 
Long. 5 millim. 
Hab. Guatemata, Cerro Zunil 4000 to 5000 feet, Las Mercedes 3000 feet (Champion). 
Antenne rather slender, but decidedly thickened towards the extremity, very loosely 
articulated and evidently setulose; third joint slender, hardly longer than second ;
