646 STAPHYLINIDA. 
13. Stenus repletus. (Tab. XVII. fig. 5.) 
Robustus, niger, subeneo-tinctus, perrugosus; palpis flavis, antennis pedibusque testaceis, illarum clava 
obscuriore ; abdomine densissime punctato. 
Long. 63 millim. 
Hab. Guatemata, El Tumbador, San Joaquin, Cerro Zunil, Tamahu, San Gerdénimo 
(Champion). 
Head bisulcate, the intermediate space moderately broad, not carinate. Thorax 
rather short, unimpressed, very deeply rugose-sculptured. Llytra a good deal longer 
than the thorax, very deeply and coarsely rugose ; no individual punctures can be distin- 
guished, and the erosions are vermiculate rather than granulose. Hind body densely 
punctured, with scanty moderately long pubescence ; the segments not cuspidate. In 
the male the legs are much incrassate, the under surface of the body more densely 
pubescent, the metasternum deplanate and densely punctured, the terminal ventral 
plate with a large deep excision ; the middle tibiz are minutely mucronate at the apex ; 
the hind legs very thick, the femora with the hind margin incrassate in the middle, 
pubescent at the base, the tibize obtusely angulate internally in the middle and emar- 
ginate below this. Six examples. 
B. Abdomen immarginatum. 
14. Stenus fauvelianus. (Tab. XVII. fig. 6.) 
Elongatus, angustulus, niger, eneo-tinctus, nitidus; palpis pallide flavis, antennis pedibusque testaceis, femo- 
ribus extrorsum fuscescentibus; capite medio anguste carinato ; prothorace elytrisque dense fortiterque 
punctatis, subrugosis ; abdomine albido-pubescente, segmentis basalibus fortiter, cxteris obsolete parceque, 
punctatis. 
Long. 42 millim. 
Hab. Mexico, San Pedro in Coahuila (Palmer), Cordova, Jalapa (Hége), Yautepec 
near Morelos (Flohr); GuaremaLa (Sallé), near the city, San Gerdénimo, Cubilguitz 
(Champion) ; Nicaragua, Chinandega (Sad/é) ; Panama, David, Bugaba (Champion). 
The male of this species has the femora slightly incrassate ; the terminal ventral 
segment with a rather elongate excision, that preceding it with a depression on the 
apical portion, margined on each side with very dense, fine pubescence. 
S. fauvelianus is no doubt very closely allied to the Colombian S. chalcites, Er., and a 
specimen of it was labelled with that name in Chevrolat’s collection; but Erichson’s 
description of the male characters renders it more probable that our insect is distinct. 
It was ticketed S. sulcipennis, Fauv., in Sallé’s collection; but I have not preserved 
the name, as it is not so applicable to this species as to some of the allies, and have 
preferred a name in honour of the talented entomologist of Caen. It is apparently one 
of the commonest of the Steni of our region ; we have received a good series both from 
Mexico and Guatemala, and also four examples from the State of Panama.
