BRACHYPEPLUS. 279 
Hab. Guatemata, Las Mercedes, El Reposo (Champion); Panama, Bugaba, Volcan 
de Chiriqui (Champion). 
Head broad, densely punctate, without trace of any prominent angle behind the eyes. 
Thorax much broader than long, truncate in front, with slightly obtuse front angles, 
nearly straight at the sides, the hind angles nearly rectangular, slightly obtuse ; the 
surface densely, rather finely, subobsoletely punctate. Elytra with regular but very 
feeble coste, and with obsolete punctuation between them. Dorsal segments closely 
punctate, a little shining. Male with a very distinct supplementary segment. Five 
specimens. 
4. Brachypeplus staphylinoides, sp. n. (Tab. VIII. fig. 21, 3.) 
Perdepressus, parallelus, dense subtilissime punctatus, subtilissime pubescens, fusco-ferrugineus vel nigro- 
fuscus, opacus, antennis pedibusque rufis ; capite post oculos angulo genali acute prominulo. 
Long. 3-34 millim. 
Hab. Guaremata, El Tumbador, Cerro Zunil, Zapote, San Gerénimo (Champion) ; 
Panama, Bugaba, Volcan de Chiriqui, Tolé (Champion). 
Head broad, closely and finely punctate, the hind angle slightly projecting outwards 
behind the eye. Thorax transverse, very slightly emarginate in front, the sides nearly 
straight, the hind angles rectangular, the surface very densely and finely punctate. 
Elytra extremely finely costate, the sculpture between the coste quite obsolete. 
This little insect greatly resembles the members of the genus Omaliwm in the 
Staphylinide. It is easily distinguished from B. brachypterus by the prominent angle 
behind the eye. We have received nearly thirty examples of the species; it varies a 
little-in size and a good deal in colour. 
5. Brachypeplus conoteloides, sp. n. (Tab. VIII. fig. 24.) 
Subdepressus, fusco-ferrugineus vel nigro-fuscus, tenuissime pubescens, subopacus ; prothorace fortiter punctato, 
transverso, angulis omnibus rotundatis; elytris subtiliter costatis. 
Long. 33 millim. 
Hab. Mexico, Teapa (Hége); Guaremata, Senahu (Champion); Nicaraeua, Chontales 
(Janson). 
Head broad, densely and rather coarsely punctate. Thorax nearly truncate in front, 
the anterior angles nearly as much rounded as the posterior ones, coarsely punctate, 
the punctuation coarser and more definite along the middle than at the sides. 
Scutellum rather large, finely punctate. Elytra with fine, definite lines, and a close, 
very fine punctuation between them. Hind body subacuminate. Male with a small 
supplementary dorsal segment. 
We have received four specimens of this species: it varies in colour. Although very 
similar to its only American congener B. convexus, Murray, it is quite distinct, as it 
does not possess the very remarkable male characters of the Bahian species, and the 
pygidium is different in form.
