3240 STAPHYLINIDE. 
Hab. Guatemaua, Cerro Zunil 4000 to 5000 feet (Champion). 
Antenne moderately long and stout, with three basal joints yellow, the penultimate 
joint slightly longer than broad; palpi infuscate yellow. Thorax much narrowed in 
front. Elytra longer than the thorax, only sparingly punctured. 
The colour of the elytra distinguishes this insect readily from H. remota, and, more- 
over, it is considerably more slender. Only one individual has been found. 
8. Heterothops orbicularis. (Tab. VII. fig. 24.) 
Nigricans; antennarum basi et apice, pedibus elytrisque testaceis ; capite suborbiculari, oculis a collo parum 
distantibus ; elytris parce, abdomine crebrius subtiliter, punctatis. 
Long. 44 millim. 
Hab. Guatemata, San Juan in Vera Paz (Champion); Panama, Volcan de Chiriqui 
3000 to 4000 feet, Boquete 3500 feet (Champiun). 
Antenne rather short and not stout, the two or three basal joints red or yellow, the 
following dark, the apical joint again paler. Head small, the large eyes occupying 
nearly all the sides, so that only a short interval (not one fourth the length of the eye) 
separates the eye from the neck. Elytra only about as long as the thorax, sparingly 
punctate. Hind body finely punctate, the hind margins of the terminal two segments 
pale. 
Five examples of this species have been found. The specimen figured is from 
Panama. 
4. Heterothops tenuicornis. 
Minor, angustula, nigricans; antennis tenuioribus fuscis, pedibus fusco-testaceis, elytris brunneis ; capite sub- 
orbiculari, oculis a collo parum distantibus ; abdomine crebre subtiliter punctato. 
Long. 3? millim. 
Hab. GUATEMALA, near the city (Champion). 
Antenne remarkably slender, the two basal joints rather thicker than the others. 
Elytra scarcely longer than the thorax, rather sparingly punctured. Hind body very 
acuminate. 
The slender antenne are peculiar to this species. Only a single example has been 
found. 
ACYLOPHORUS. 
Acylophorus, Nordmann, Staph. p. 127, t. 1. f. 9; Erichson, Gen. et Spec. Staph. p. 519. 
This is a well-known genus, of wide distribution in both hemispheres, extending 
even to Australia. About twenty-four species are known, so that our region has more 
than an average number of species, and in fact it is probable that the warmer portions 
of the New World are the headquarters of the genus.
