Palechthus glabratus, 0. sp. 
Elongatus, fusiformis, convexus, glaber, piceus; capite rostroque 
erebre subtiliter punctulatis ; thorace latitudine paulo longiori, 
nitido, crebre evidenter punctato, basi medio impressa ; elytris 
thorace paulo latioribus post medium gradatim arcuatim angus- 
tatis, nitidis, striatis, striis punctatis, interstitiis perparum con- 
vexis, subtiliter coriaceis, dimidio apicali fulvo-hirto; metasterno 
subtiliter (latera versus obsolete) punctulato, parapleuris angus- 
tissimis; pedibus punctatis, fulvo-pubescentibus, tibiis sat as- 
peratis. 
Long. (rostr. excl.) 12 millim., lat. 43 millim. 
The rostrum has a fine, smooth, raised line, commencing at 
around fovea which is between the eyes and extending to 
the apex. ‘The eyes are distinctly narrowed below. ‘The 
thorax is scarcely arcuate at the sides, shghtly narrowed from 
near the base to the front, and also at the extreme base. 
The elytra have the shoulders obliquely rounded off with a 
slight impression above; the strie are distinct posteriorly, 
but at the base are only represented by lines of fine punc- 
tures. he pubescence is stiff and dense at the apical decli- 
vity, particularly on the suture, and forms a slight tuft at the 
apex of the fourth stria. 
Hab. Nightingale Island (Oct. 17, 1873). 
Three examples. Probably the pubescence would be found 
in fresh examples to exist, to a small extent, on the thorax 
and base of the elytra. 
Palachthus cossonoides, n. sp. 
Elongatus, subparallelus, depressiusculus, pallide piceus, parce flavo- 
setosus ; thorace fere parallelo, ad apicem ipsum angustato, crebre 
evidenter punctato, depresso ; elytris ad apicem arcuatim angus- 
tatis, leviter striato-punctatis, interstitiis parum nitidis, punctis 
parvis setigeris sat discretis seriatim dispositis. 
Long. (rostr. excl.) 73 millim., lat. 24 millim. 
Much more depressed than the foregoing species, and more 
parallel in outline. The rostrum is relatively a little shorter 
(a little shorter than the thorax), only very slightly arched, 
the punctuation obscure and confused, the fovea between the 
eyes almost wanting. The thorax is more parallel, only nar- 
rowed just before the apex and at the extreme base; with no 
dorsal impression. ‘The elytra are more depressed, and conse- 
quently the posterior declivity is more gradual; the strie are 
represented by lines of fine (generally elongate) punctures ; 
the pubescence is more sparse and more equally distributed. 
Hab. Nightingale Island. A single example.
