662 STAPHYLINIDA. 
52. Stenus godmani. (Tab. XVII. fig. 13.) 
Niger, supra calvus, sat nitidus; antennis, palpis pedibusque pallide flavis; capite excavato, disco fortius 
parciusque punctato ; prothorace densissime fortiterque punctato, quam elytris paullo breviore. 
Long. 6 millim. 
Hab. Mexico, Cordova (Sailé), Jalapa (Hoge); GuatemaLa, Zapote (Champion). 
Palpi very long, their terminal joint about twice as long as the space separating the 
antenne at their insertion. Antenne very long, the club elongate but very abrupt, the 
eighth joint being long and very slender. Head rather deeply excavate, not sulcate, 
evidently more coarsely and sparingly punctured on the middle. Thorax very elongate, 
nearly twice as long as broad, subcylindric, a little curved at the sides; coarsely and 
very densely punctured, almost rugose. FElytra a little longer than the thorax, with 
rather abrupt shoulders, the punctuation coarser and not quite so close as that of the 
thorax. Hind body coarsely, moderately closely punctured, the terminal segment 
obsoletely punctate. Male with the ventral plate of the armature large, flat, deeply 
emarginate at the tip; the terminal (seventh) segment with a very deep and broad 
sharply-defined excision which is rounded in front; the sixth segment impressed and 
finely pubescent along the middle, with the sides of the impression a little elevated 
behind; the four preceding segments flattened and glabrous in the middle behind. 
53. Stenus cribriceps. (Tab. XVII. fig. 15.) 
Nigro-subviridis, nitidus ; antennis, palpis pedibusque flavis ; capite leviter excavato; dense punctatus; abdo- 
mine basi crebre sat fortiter punctato, segmentis apicalibus multo obsoletius et parcius punctatis. 
Long. 6 millim. 
Hab. Nicaracua, Chontales (Janson); Panama, Volcan de Chiriqui 2000 to 3000 feet 
(Champion), Chiriqui (22dée). 
Antenne and palpi very elongate. Head broad, coarsely but evenly punctate, slightly 
excavate, flat, with a very slight, fine, minute carination along the middle. Thorax 
nearly twice as broad as long, very slender, very densely punctured, subrugose. FElytra 
densely and coarsely punctured, about as long as the thorax, the shoulders well-marked. 
Male with the segment of the armature very long ; its ventral plate simple, feebly emar- 
ginate at the tip; the preceding segment with a rather narrow, deep, angular excision ; 
the sixth segment furnished with very minute fine pubescence along the middle, and there 
is also a little of such pubescence on the posterior part of the preceding segment. 
The metallic tint, rather less developed sculpture of the hind body, and the unusually 
coarse sculpture of the under surface of the head distinguish this species, independently 
of the male characters. We have received only one example from each source: with 
the exception of the typical individual from the Volcan de Chiriqui, all are females, and 
it is possible, as they differ a little from one another, they may not all be one species. 
We figure the female example found by Ribbe in Chiriqui.
