front margin, the angles being well rounded ; antennarv orbits outwardly angulately produced 
beyond the eyes ; finely granulose (the granules black), and thinly clothed with short scale- 
like hairs of a golden-yellow color : prothorax gently convex, rather deeply eurvedly emar- 
ginate in front, front angles not produced, suh-acute ; sides a little reflexed, gently regularly 
rounded ; base a little wider than apex, sinuate ; hind angles produced, acute, directed back- 
wards ; the surface more distinctly and regularly granulose, &c., than the head : scutellum 
semi-circular, finely granulose and pubescent : elytra a little wider at base than base of pro- 
thorax ; oblong, slightly widest behind the middle ; shoulders distinct, very finely transversely 
rugulose ; punctate-striate, the punctures being rather large ; intervals a little convex, very 
finely and not at all densely granulose, each granule furnished with a short scale-like hair, as 
in the prothorax, &c. : underside thinly clothed with a fine greyish-yellow pubescence : flanks 
of prothorax rather strongly granulose, meso- and meta-sterna and their flanks more finely so • 
abdomen finely granulose-punctate, and transversely rugulose : metasternum as long as the 
first ventral segment : prosternum closely curved round the coxae : anterior tibiae expanding 
outwardly, finely muricately punctured and shortly setose : last joint of all the tarsi elongate : 
antennae reddish, thickening outwardly, joint 3 nearly as long as 4-5 united, 8-10 trans- 
verse and gradually broader, 11 large, ovoid.

Penthicus (loboderus) gracilis. 
I have submitted this species to M. J. Miedel, of Liege, who for the past five years has 
been engaged on a critical examination of the Opatricles : he returns it to me as a species 
distinct from the rvfescens of Mulsant, and has furnished me with the following differential 
characters : — 
Than rufescens — larger : prothorax more contracted posteriorly, the sides consequently 
are sub-angulated in the middle, front angles more pointed ; the punctuation, &c., different ; 
in gracilis the prothorax is somewhat closely, uniformly, and finely punctured on a very 
minutely granulose ground, and at each side the disc are some irregular foveate depressions : 
in rufescens the middle of the prothorax is somewhat sparsely covered with fine, but well- 
marked, punctures on a smooth ground, the punctuation on the sides being stronger and 
closer : the elytra in gracilis are more gradually ( longuement ) attenuated behind, hut not 
more pointed at the apex ; very faintly sulcated, the intervals somewhat sparingly covered 
with very minute granules and showing a line of small shallow punctures; there is also 
a line of very minute punctures down by the suture : in rufescens the elytra are visibly 
although very finely, punctate- striate, the intervals being finely, transversely, unequally ru- 
gulose : the abdominal segments in gracilis are somewhat thinly covered with very small 
granules, arranged in almost transverse lines ; whilst in rufescens they are well punctured : 
the legs and antennae are similar in both species, except that joints 3 to 7 of the latter are 
more elongate in gracilis.
