Tlie posterior margin of the pronotum is nearly straight, being only very slightly produced over the base
of the seutellum. I have given my reason for adopting Dr. Schaum's name for this species in preference
to Mr. Hope's in my observations on M. nigrijiennis, Schaum, next described.
The British Museum possesses a series of this species from various localities, viz. from Siara, Burmah,
Cambogia, Dacca and China, all having- a yellow seutellum—the Chinese specimens ha^ng two yellow spots on
the back of the head, whilst others from Siam, India, and Burmah have the seutellum either entirely black or
yellow at the base.

The specimen represented in the accompanying figm-e (pi. V I , fig. 7) is from Laas, Camboja, in the Collection
of Count Mniszech. It is 7 lines long and 4 broad across the shoulders of the elytra. The underside of the head is
pitchy. The anterior coxa3 are pale yellow. The mentum is strongly angulated in the middle; the anterior part
broadly ovate (fig. 7 a, the underside of the front of the head seen in front, concealing the base of the mentum).
The front of the mesosternum is fulvous in the middle. The third and fourth segments of the abdomen are sanguineous
at the sides and in the middle beneath. The whole of the abdomen is glossy and very delicately
transversely striated, as are also the 4 broad black hind femora. The basal segments of the abdomen have an
oblong impression in the unique male specimen which I have examined. The yellow sides of the metasternuni
are impuuctate and very glossy. The seutellum is impunetate except at the base. The apex of the elytra is
finely transversely striated, this part being separated from the disc by a sharp curved depression. The pygidiimi
is black, with a strong central carina and two conical tubercles.
The name of M. nigripennis was applied by Dr. Schaum and Mr. Hope to two diflerent insects, the descriptions
of which were published in the same year—1841. In such cases I think it is preferable to adopt that
given by a monographer rather than that of a describer of isolated species, and therefore I retain Dr. Seliaum's
name in preference to Mr. Hope's, although the description given by the latter was read at the Entomological
Society of London on the 1st of July, 1839.

This species is shorter and broader than 3i. melanopus from Assam. It is very glossy. My figure
and the following notes are made from M. Gory's typical specimens communicated liy the late Dr. Schaum.
The head beneath, with the maxilla; and palpi, are dark luteous, the mentum yellow; the hind part of the head
is dark brown; the coxaj of the fore legs yellow; the deflexed anterior angles of the pronotum have a black
border; the front of the mesosternum is flat, perpendicular, and fulvous; the posterior angles of the epimera
are deflexed and yellow coloured; the third and fourth segments of the abdomen are dark blood red ; the second
and fifth have a small ferruginous patch in the middle of each. The male has the three basal segments of the
abdomen marked with an oval longitudinal impression. The pygidium is black, with a raised trieuspidate
space, having a shai-p longitudinal central carina.
There is a variety of this species in the British Museum, collected in India by Colonel WTiithill, nearly
9 lines long, black, with the lateral margins of the pronotum yellow, with a black spot; the head and anterior
coxiE yellow ; the exposed part of the posterior coxa3 pale yellow; the abdomen black, with a red central vitta,
and the middle segments with a blood-red spot on each side.

The antenna; are chestnut, with the club fulvous. The under side of the head is black; the mentum is
yellow, strongly angalatod in the middle, the anterior portion being obliquely truncate and broadly ovate in
form. The disc of the pronotum is nearly smooth, but the sides are rather thickly punctate; the anterior and
posterior margins are narrowly black, and on each side of the middle is a black longitudinal mark, the anterior
half narrow, but forming- a lozenge-shaped spot united behind to a large nearly rounded spot; there is also a
small round spot in front of the middle of each side. The disc of the elytra is sparingly punctate, but the sides
more thickly, the punctures being more transverse. The apex of each elytron is finely transversely punctatestriate,
being separated from the disc by a sharply defined curved impression. The terminal hook of the maxillae
is very acute, slender, and arched, the teeth of the inner lobe being short and robust. The mesosternum.
forms a nearly globose tubercle slightly advanced between the base of the middle legs.
The abdomen iu the male has the basal segments longitudinally impressed.
