400 STAPHYLINIDA, 
9. Philonthus alticola. (Tab. X. fig. 7.) 
Elongatus, nitidus, nigricans ; capite, thorace elytrisque wneis, antennis pedibusque piceis, tarsis palpisque rufis ; 
prothorace lateribus posterius haud sinuatis; elytris quam ille fere brevioribus, cumque abdomine parce 
punctatis. 
Long. 17 millim. 
Hab. Guatnmata, Totonicapam 8500 to 10,500 feet (Champion). 
This, though a very distinct species, is still, I think, a real ally of P. furvus; it has 
the head rather longer, so that the eyes are farther from the vertex, the thorax scarcely 
at all sinuate behind, and the elytra rather shorter and narrower at the shoulders, 
indicating the probable absence of wings. The antenne are rather slender, with the 
penultimate joint about as long as broad. Only one example (a female) has been 
found. 
10. Philonthus testaceipennis. 
Philonthus testaceipennis, Er. Gen. et Spec. Staph. p. 485,91; Solsky, Hor. Soc. Ent. Ross. v. 
p- 127, 37. 
Hab. Mxxico! ®, near the city (Flohr), Las Vigas (Hoge), La Parada, Yolos (Sallé). 
In the male of this species the front tarsi are only slightly dilated, but the excisions 
of the ventral plates of the penultimate and terminal segments are remarkably large 
and the hinder tibie are slightly curved. 
11. Philonthus hogei. (Tab. X. fig. 6.) 
Niger ; capite thoraceque nitidis, elytris rufo-testaceis, cumque abdomine crebrius subtiliter punctatis. 
Long. 14-16 millim. 
Hab. Mexico, Las Vigas (Flohr, Hoge), Milpas (Forrer). 
This insect is very similar to P. testaceipennis, but is distinguished at a glance by the 
closer punctuation of the elytra and hind body, and by the darker yellow colour of the 
wing-cases; the head and thorax have a very faint bluish tinge. In the male the 
front tarsi are not much dilated, the penultimate ventral segment has scarcely any 
emargination, and the notch on the terminal segment is not large; the hind tibie 
are quite straight. 
Hoge met with a very large series of this conspicuous insect. Our figure represents 
a male example. 
12. Philonthus piceatus. (Tab. X. figg. 8, 9, et 10.) 
Philonthus piceatus, Nordm. Staph. p. 851; Er. Gen. et Spec. Staph. p. 446”.
