The details of the month of this species (represented in figs. 2 a, 3 b, and 2 e) are described in the generic
characters given above. The thorax and elytra are covered with small oval cicatricose punctures, each emitting
a small reddish or luteous seta from its base ; the luteotis scales upon the elytra form an irregular dentate fascia
across the middle, and a transverse one between the middle and apex, followed by some irregular spots. The
presternum has an acute deilexed spine in front of the anterior coxaj. The pygidium is convex, and entirely
covered with pale-luteous squamosity. The body beneath is also covered with similar scales and with whitish
buff set® (especially on the under side of the legs, which are almost destitute of scales). The third and fourth
segments of the abdomen are marked with two black transverse spots in the middle.

STN. : Pilinurgus mbumlatus. Westw. MS; Schaum, Yerz. Lam. Melit. p. 62.
This species is larger than the preceding, from which it is chiefly distinguished by its more hexagonal prothorax,
and more posteriorly attenuated and less truncated elytra. The front margin of the clypeus is rather
elevated, and the disc of the head is thiekl}' marked with small cicatricose punctures ; the prothorax has the
middle of the lateral margins angulated, and the posterior margin is nearly straight and much narrower than the
base of the elytra. The prothorax and elytra are covered with shallow irregular cicatricose punctures, each producing
a short black seta. The disc of the elytra is flat, the sides suddenly deflexed, and separated from the disc
by a scarcely elevated carina. The body beneath is thickly clothed with dirty greyish-buflf squamosity and
similar coloured seta3, and the second, third, and fourth segments of the abdomen are marked in the centre
beneath with two transverse black spots.
SPECIES 3 (53)—PILINURGUS DESPECTUS.
PLATE IX, Eic. 3.
Late obovatus, supra depressus, obscurus piceo-niger, luteo parum squamulosus, elytris magis piceis; capite
parvo; clypeo rotundato, tenuiter marginato; prothorace transverso lateribus in medio margineque postico rotundatis,
punctis minutis cicatricosis notato; elytris in medio dorso subplanis, obsenris subvelutinis, maculis nounullis
indistinctis luteo-serieeis, punctis subdistantibus minime profundis, apice singuli rotundato, et sub humeris
profunde emarginatis; pygidio in medio paullo earinato, spiraeulis 2 posticis conicis; pedibus brevibus; tibiis

Habitat; Siam (Mouhot). In Mus. Britaun., Oxoniaj et W. W. Saunders.
I am reluctantly induced to place this Siamese insect in the Genus Piliimrgus, hitlierto composed of species
from Western Africa, with which it agrees in its obscure setose appearance, and in the structure of the
maxilla;, which have a short porreeted galea, obtuse at the tip, whilst the mando is also porrected and obtusely
Ijidentatc (pi. IX, fig. 3 a). The mentum (fig. 3 b) is nearly square, with the fore margin slightly rounded ; the
middle of the disc is somewhat angulated, with two large impressions in the anterior half, having a central raised
ridge between them. The presternum is armed with a deilexed flattened spine in front of the anterior eoxEe ;
the abdomen beneath is convex ; the pygidium is marked with two large oval depressions ; the metasternum is
simple in front between the middle coxa;. The length of the elytra is not quite equal to I | times the width of
the middle of the prothorax ; the punctures at the base of the elytra are large, but shallow, and wide apart.
The species appears liable to be affected by grease, as some of the specimens which I have seen are quite obscure.
GENUS 18—TRICHOPLUS.
(Burmeister, Handb. iii. p. 660, 1842 ; Gen. Ins. quajd. No. 36.)
Corpus oblongum planum, nigrum nitidum ; caput latum in medio vertieis nodulosum; clypeus brevis
transversus subsinuatns ; antenna; articulo primo máximo. Mandíbula; basi dilatata;, dente molari angusto
instruetaì, parte externa cornea apice obtuso. Maxillse compresste, galea magna cornea, basi curvata, bidentata;
mandonis dente longo gracili apice tridenticulato (fig. IO iT). Mentum transversum fere planum, tenue, lateribus
rotundato-dilatatis, parte antica subito angustiori, disco medio paullo concavo setoso. Prothorax magnus
lateribus rotundatis. Elytra oblonga parallela, reg-ione scutellari depressa. Pedes breves compressi. Tibia;
omnes inermes. Tarsi oinnes 3-articulati. Presternum ante pedes anticos in spinam deflcxam compressam
apice dilatato-porrectum (fig. 10 li). Mesosternum carinatum obtusum, hand porreetum (fig. 9 a).
The simple unarmed tibia;, and the 3-jointed tarsi, at once distingmsh this genus from the rest of the
family. Hitherto the genus has only comprised one described species of remarkable character. A second,
still more striking, was kiudly communicated to me for this Jlonograph, from the Royal Museum of Stockholm,
liy the late Professor Boheman.
SPECIES 1 (54)—TRICHOPLUS L/EVIS.

antice panilo latioribus, subtiliter pnnctato, elytris oblique aeicnlatis punctatis, regione scutellari lasvissima;
pedibus valde compressis.
