304 STAPHYLINIDA. 
§ 2. Epipleura largely developed, perpendicular, being inflexed and applied to the inner 
face of the elytra, so that the line limiting it internally stands out even at the 
base but little from the inner face of the wing-case. 
15. Erchomus rutilus. 
Tachinus rutilus, Er. Gen. et Spec. Staph. p. 2731. 
Hab. Mexico, Cordova (Sailé); Britiso Honpuras, Belize (Blancaneaux); GUATEMALA, 
Guatemala city and San Gerénimo (Champion); Nicaragua, Chontales (Janson).— 
ANTILLES, Porto Rico 1, St. Thomas!; SourH America, Colombia 1, Bahia (Castelnau). 
16. Erchomus cinctiventris. 
Sat convexus, nitidissimus, niger; antennis rufis, basi pedibusque testaceis, prothoracis marginibus, elytrorum 
abdominisque segmentorum marginibus dilute piceis ; thorace elytrisque levigatis, abdomine parce profunde 
punctato. 
Long. 33 millim. 
Hab. Guatemata, Guatemala city (Champion). 
Very shining, black, with the thorax piceous; the lateral and posterior margins of 
the elytra more or less dilute in colour, and the terminal portions of the rings of the 
hind body very distinctly rufo-piceous. The antenne are rather short, the three basal 
joints yellow, the others obscure red, the two or three penultimate joints not quite so 
long as broad. Thorax large, quite impunctate, the base slightly sinuate on each side ; 
the hind angles rounded, not produced backwards. Elytra almost impunctate, with an 
obscure depression near the side behind; the outer hind angles obtuse, scarcely rounded. 
Hind body shining, with a good many rather coarse and deep punctures on each segment, 
not extending, however, to the hind margin. Legs short. Mesosternal carina only 
slight, and without anterior elevation. 
A large series, showing scarcely any variation except in the more or less dilute piceous 
colour of certain parts, has been found of this species; it and /. vicinus appear to be 
rather closely allied to the Amazonian LE. inclusus. A North-American insect, probably 
E. levis, Lec.,is extremely similar to the two Central-American species, but differs from 
both by the punctuation of the hind body. 
17. Erchomus levis. 
Coproporus levis, Lec. New Sp. Col. i. 1868, p. 31°. 
Erchomus levis, Horn, Trans. Am. Ent. Soc. 1877, p. 108°. 
Hab. Norru America, Southern States 1, Gulf States Mexico, Cordova (Salié). 
A single individual from Sallé’s collection may apparently be referred to this species, 
though the head and thorax are rufescent in colour, the latter being, however, piceous 
on the disk.
