its base like the propygidium and the apex is smooth; the 
prosternum, anterior lobe very large, keel narrow between 
the cox, with a loop-shaped ‘stria, “which joins behind; the 
mesosternum is widely emarginate, stria complete and is close 
to the anterior edge; the metasternum is longitudinally 
canaliculate in the middle; the anterior tibie are 4-dentate 
and somewhat dilated. 
The size and form of this remarkable species is similar to 
Pachycrerus viridis, Mars.  Platysoma canalicolle, Mars., 
has a stria which entirely surrounds the thoracic margin, but 
it is not so deep and conspicuous as in P. extrarium. 
_ Hab. Queensland, Australia. 
Pachycrerus morulus, sp. 0. 
Oblongus, parum ellipticus, subcylindricus, piceo-niger, nitidus ; 
antennis pedibusque rufo-brunneis; capite punctulato, stria 
antice integra ; elytris, striis subhumerali externa, 1-4 suturalique 
integris, 5 basi abbreviata vel evanescenti; prosterno bistriato ; 
mesosterno antice haud striato. 
L. 33 mill. 
Oblong, somewhat elliptical and cylindrical, nearly black, 
with the antenne and legs reddish brown; the head impressed 
anteriorly, stria complete and anteriorly straight, surface 
evenly punctulate; the thorax wider than broad, surface 
clearly punctured, punctures varying in size, with a very fine 
punctuation between the larger points, lateral margins are 
narrowly free of punctures, the lateral marginal stria continues 
as a very fine stria behind the eye, but it is interrupted 
behind the middle of the neck; the elytra—strie, external 
subhumeral fine and complete and at the apex turns inwards 
and terminates at a point behind the second stria, internal 
fine, basal, and oblique, 1-4 complete, 5 abbreviated at the 
base or just visible in certain lights, sutural almost complete, 
arrested at a point level with the scutellum ; the propygidium 
and pygidium clearly punctured, punctures are somewhat 
irregular and leave the pygidium smooth at its apex; the 
prosternum is narrow, bistriate, strize not meeting anteriorly, 
are nearly parallel at the sides, and widen out slightly between 
the coxe; the metasternum is very feebly bisinuous on either 
side of the acumination, which is small and obtuse; the 
meso- and metasterna have each a distinct lateral stria and 
the first segment of the abdomen has two fine lateral striae on 
either side ; the anterior tibia have three large teeth in the 
middle and smaller ones outside of them. 
The elliptical subcylindrical form of this species is unlike
