NAUSICOTUS.—GLENUS. 369 
Trigonopselaphus opacipennis, Shp., and one or two undescribed South-American 
species, belong to the genus. 
1. Nausicotus spectabilis. (Tab. IX. fig. 11.) 
Capite thoraceque aureo-purpureis, fulgidis ; elytris, pectore abdomineque fusco-nigris, opacis, hoc segmento 
ultimo pedibusque testaceis ; antennis rufo-obscuris, dimidio apicali pallide testaceo. 
Long. 22 millim. 
Hab. Nicaracua, Chontales (Belt). 
Antenne not elongate, and but little thickened externally ; the two or three penulti- 
mate joints rather broader than long. Palpi and parts of the mouth flavescent. Head 
with numerous punctures near the inner margins of the eyes, densely punctured 
behind, and with four or five punctures near the front in the middle. Thorax rather 
longer than broad, on each side of the middle with a longitudinal series of about eight 
distant punctures, with punctuation near the front and lateral margins, but with very 
few punctures between these and the discoidal series. Elytra very opaque, with very 
obsolete punctuation, rather closely pubescent. Hind body closely and very finely 
punctured, very dull, the apical segment pale yellow ; the extreme hind margin of the 
preceding segment is also of this colour, and so are the anal styles, the latter, however, 
are fuscescent behind, but their terminal pubescence is yellow. The legs are yellow, with 
distinct black spinules. The unique individual is a male, and has a broad, very shallow 
. notch on the last ventral plate.

This is one of the most distinctive of the genera of South-American Staphylinide. 
It is not found out of Tropical America, nor has it anywhere, so far as we know, any 
near ally. The species found in our region are both much inferior to the South- 
American forms in the stature of their individuals, and are apparently of great 
rarity. I had not anticipated the extension of this genus to Mexico previous to Mr. 
Flohy’s discovery of a species there. 
1. Glenus coxalis. 
Glenus coxalis, Sharp, Trans. Ent. Soc. Lond. 1876, p. 425. 
Hab. Panama (Henry Edwards). 
2. Glenus flohri.’ (Tab. IX. fig. 12.) 
Rufo-fulvus; thorace rufo-aureo, scutello nigro, abdomine nigro-variegato; capite thoraceque densius fortiter 
punctatis, cumque elytris fulvo-pubescentibus ; thorace linea lata in medio levigata. 
Long. 15 millim.
