666 STAPHYLINIDA. 
distinctly pubescent at the base. Male with a rather large excision on the last ventral 
plate, and a finer punctuation and pubescence on that preceding it. 
62. Stenus chontalenus. 
Niger, evidenter pubescens, parum nitidus, dense punctatus ; antennis, palpis pedibusque flavis; capite leviter 
‘ excavato; elytris abdomineque segmentis basalibus singulo ad basin densius albido-pubescente. 
Long. 43-5 millim. 
Hab. Nicaracua, Chontales (Janson). 
This insect is very closely allied to S. sagax, but is rather more slender, without 
metallic tint, and with the punctuation more indistinct on account of the more con- 
spicuous pubescence. The male characters are almost the same. Three examples. 
63. Stenus deceptor. 
Niger, subnitidus, dense punctatus; antennis, palpis pedibusque flavis, illis minus elongatis; capite obsolete 
bisulcato. 
Long. 6 millim. 
Hab. GUATEMALA, near the city (Champion). 
Head moderately broad, not at all excavate, broadly indistinctly bisulcate, closely 
punctate. Antenne only moderately long, gradually thickened from the sixth joint 
onwards. Thorax not twice as long as broad, a good deal curved at the sides, coarsely 
and closely punctured. Elytra slightly longer than the thorax, coarsely and closely 
punctured. Hind body at the base moderately coarsely, at the apex quite obsoletely, 
punctured. One female. 
This species is readily distinguished from S. cylindricus and S. albipes by the shorter 
antenne and the subsulcate head; it is larger than S. flohri, with closer punctuation 
and a differently shaped hind body, the segments being scarcely at all constricted. 
64. Stenus flohri. 
Angustior, niger, nitidus; antennis, palpis pedibusque pallide flavis; capite vix excavato, utrinque leviter 
sulcato ; prothorace elytrisque fortiter punctatis; abdomine minus argute punctato, subtiliter pubescente. 
Long. 5 millim. 
Hab. Mexico, Cuantla (Flohr). 
I have received only one example of this species, but, though in bad preservation, 
there is no doubt of its being distinct; it is a male, and has only a very short broad 
emargination of the last ventral segment, the preceding segment being slightly depla- 
nate and a little pubescent along the middle. The female will, no doubt, be readily 
distinguished from S. albipes by the head being a little depressed on each side and the 
hind body more obsoletely punctured, with scanty but distinct pubescence.
