By Dr. Suarp. 
Tyrus mutandus, n.sp. Rufescens, antice angustatus, sat dense setosus, 
impunctatus; pedibus elongatis; elytrorum stria suturali basi foveolato. 
Long. 13 M.M. 
Antenne, longer than head and thorax, reddish yellow, first and second 
joints about equally stout; first, longer than second ; second, about as long 
as broad; third, fourth, and fifth, about equal in length, each a little longer 
than broad ; joints six, seven, and eight, slightly shorter than the preceding 
joints, especially the eighth; ninth jomt, stouter and longer than the eighth, 
about as long as broad; tenth joint, slightly broader and a little shorter 
than the ninth, not quite so long as broad; eleventh joint, stout, oval, as 
long as the two preceding ones, but stouter than they are. Head, narrow, 
not half the width of the elytra, the antenne approximate at their inser- 
tion, the tubercules contiguous, but separated by a well-marked channel; on 
each side near the eye is a distinct fovea ; the vertex is elevated, smooth, 
and shining. Thorax, longer than broad, only about half as broad as the 
elytra, much narrowed in front, behind the middle with a very deeply- 
impressed curved line, which terminates on each side in a deep, but ill- 
defined impression ; it has no punctures, but is clothed with a short upright 
pubescence. Elytra, bright reddish-yellow, much narrowed at the shoul- 
ders, each with a sutural stria which is very deeply impressed at the base, 
and outside this a short, deep, and broad humeral impression; they have 
no punctuation, but are clothed, especially about the sides, with a long, 
fine, upright, pale pubescence. Hind body short and convex, pubescent, 
the first segment only slightly longer than the second. Legs long and 
slender, the claws of the tarsi small. 
Pselaphus pauper, n. sp. Rufo-castaneus, nitidus; capite medio impres- 
sione magna; prothorace elongato, impressione basali curvata bene 
distincta ; elytris stria discoidali sat profunde impressi. Long. corp. 24 
mim. 
Obs.—P. lineata, King, peraffinis ; prothoracis impressione magis pro- 
funda, ejusque parte basali nitida, elytro-rumque stria discoidali bene 
distincta, differt. 
Antenne, longer than head and thorax, the ninth joint but little 
thickened. Head, with the channel between the frontal processes rather 
broad, and terminating between the eyes in a deep impression, which is 
continued backwards along the vertex. Thorax, not more than half the 
width of the elytra, longer than broad, not much dilated in the middle, in 
front of the base with a deep curved impression, the part behind this 
shining like the rest of the upper surface. Elytra, longer than the thorax,
