7. Lithocharis alticola. 
Tenuis, fusca; capite nigricante, omnium dense subtilissime punctato, opaco; elytris quam prothorax fere 
longioribus. 
Long. 4 millim. 
Hab. Guatemaa, Quiche mountains 7000 to 9000 feet (Champion). 
Antenne slender, the penultimate joint as long as broad. Head small, a little nar- 
rowed in front. Thorax elongate, rather longer than broad, densely punctate, without 
carina. Elytra scarcely so long as the thorax. 
This is a distinct little species, of which six examples were obtained; they are all in 
a bad state of preservation. 
ADEROCHARIS. 
Corpus latum, depressum, densissime punctatum. Caput quadratum, collo sat lato. Tarsi anteriores dilatati. 
Prosterni processus parum productus, epimeris inter sese valde distantibus. Tarsi posteriores evidenter 
quinque-articulati, articulo basali quam secundus multo longiore. 
This genus is distinct from Lithocharis by the comparatively broad neck and the 
dilated front tarsi, while from Medon it departs by the smaller development of the 
pieces contiguous with the front coxe. The maxillary palpi are elongate, the terminal 
joint very minute, being excessively slender as well as short; the labrum » is large, 
obscurely unidentate in the middle. | 
The genus has a wide distribution in the New World, as it will comprise the North-. 
American LL. corticina, Grav., as well as the South-American JL. hepatica, Er., and the 
species here described. The Eastern L. staphylinoides, Kr., with a similar facies, will 
form another new genus. 
Same habits as Scopewus (Champion).

Mr. Champion procured a good series of this species near the city of Guatemala, 
but from each of the other localities we have only one or two examples. The specimens 
agree closely, except that those from the State of Panama are smaller, agreeing in this
