496 STAPHYLINIDZA. 
capite thoraceque subquadratis, illo ad angulos posteriores crebre fortiter punctato; elytris abdomineque 
crebre minus subtiliter punctatis, pallide fusco-pubescentibus. 
Long. 8-9 millim. 
Hab. Mexico, Las Vigas (Hége); Guatemata, Duefias (Champion). 
Antenne rather shorter than the head and thorax, with the penultimate joint not 
longer than broad. Head almost as broad as the thorax, with numerous very coarse 
punctures which do not cover the middle. Thorax about as long as broad, nearly 
straight at the sides, the discoidal series consisting of seven rather coarse punctures ; 
there are also five other punctures on each side between the discoidal series and the 
margin. Scutellum densely punctate. Elytra rather closely and, though not coarsely, 
very definitely punctate, and ofa dull brassy colour. Hind body rather coarsely punctate, 
the three basal segments each with a deep transverse impression. The middle coxe 
are rather widely separated. 
The male has the front tarsi broadly dilated, and a rather large notch on the last 
ventral plate; in the female the front tarsi are a little dilated. A female from Duefas 
is figured. 
80. Philonthus atricolor. 
Niger, parum latus, subparallelus ; pedibus piceis ; capite oblongo-ovato ; thorace serie dorsali circiter 7-punctato ; 
elytris abdomineque crebrius punctatis. 
Long. 73 millim. 
Hab. Mexico, Capulalpam (Sallé), Cerro de Plumas (Hége); GuatEmaLa, Totoni- 
capam 8500 to 10,000 feet (Champion). 
Antenne moderately long, scarcely thicker externally, the penultimate joint about as 
long as broad. Head rather long and narrow, nearly as broad as the thorax ; the latter 
almost straight at the sides, just perceptibly narrowed in front, and, like the head, of an 
intense shining black colour. Scutellum dull, indistinctly punctate. Elytra about as 
long as the thorax, rather closely and, though not coarsely, very definitely punctate. 
Hind body finely and moderately closely punctate. 
The male has quite simple front tarsi, and an extremely small emargination on the 
last ventral plate. 
Four examples were found in Guatemala, and but two in Mexico; I find no specific 
difference in the specimens from the two localities, although those from Mexico have 
the antenne paler and apparently a little more elongate and slender.
