658 STAPHYLINIDZA. 
42. Stenus megops. 
Nigerrimus, nitidissimus; palpis pedibusque dilute flavis, femorum apicibus angustissime fuscescentibus ; 
antennis testaceis, extrorsum fuscescentibus ; capite lato, parum punctato, profundissime bisulcato; pro- 
thorace brevi, basin versus angustiore ; elytris convexis, quadratis, parce fere grosse punctatis. 
Long. 4 millim. 
Hab. Panama, Bugaba (Champion). 
Head very broad, the median elevation wide and elongate. Thorax a good deal 
broader in the middle, coarsely, irregularly punctate. Hind body polished and 
shining, with a few punctures on the basal segments. One female example, in bad 
preservation. Very distinct from the allied species by the deep frontal furrows; and 
in the dilute almost immaculate legs resembling S. inanis. 
Two examples. 
43. Stenus leetipes. 
Nigerrimus, nitidus ; antennarum basi, palpis, femorum tibiarumque dimidiis basalibus lete flavis, tarsis fusco- 
flavis ; grosse irregulariter punctatus; vertice plaga elevata, polita, elongata. 
Long. 47 millim. 
Hab. Mexico, Mirador (Hoge). 
Head with the median elevation very abrupt. Thorax not longer than broad, rugosely 
punctate, with a space on the middle shining. Elytra rugosely and very coarsely, but 
unequally punctured, the punctures being scanty on some parts. Hind body shining 
and polished. : 
We have received only one badly-preserved female without antenne. The species 
will be probably distinguishable by the great and abrupt contrast in the colours of 
the different parts of the legs. In 8. laceratus the bases of the femora are nearly 
black ; here the basal half is bright yellow, the outer half black. 
44. Stenus laceratus. 
Gracilis, nigerrimus, sat nitidus, rugosus; antennarum tibiarumque basibus palpisque flavis, antennis tibiis- 
que extrorsum cum tarsis fusco-flavis ; vertice medio plaga elongata, elevata, nitida ; elytris dense fortiter- 
que rugoso-punctatis, 
Long. 4? millim. 
Hab. Mexico, Yautepec, Morelos (Flohr). 
Head moderately large. Thorax about as long as broad, strongly rounded at the 
sides, rugosely punctate, with an impunctate space on the middle. Elytra rather 
longer than the thorax, very rugosely, densely, and coarsely punctate. Hind body 
very feebly punctate, sparingly furnished with a whitish pubescence ; terminal sete 
excessively minute. 
Of this species we have received only one female example. The dense rugose punc- 
tuation of the elytra readily distinguishes it.
