The posterior margin of the pronotum is nearly straight, being only very slightly produced over the base 
of the scutellum. 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. nigripennis, Schaum, next described. 
The British Museum possesses a series of this species from various localities, viz. from Siam, Burmah, 
Cambogia, Dacca and China, all having a yellow scutellum—the Chinese specimens having two yellow spots on 
the back of the head, whilst others from Siam, India, and Burmah have the scutellum either entirely black or 
yellow at the base.

Macroma Schaumii. Westw. MS. olim. 
The specimen represented in the accompanying figure (pl. VI, 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 cox 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 san- 
euineous 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 metasternum 
are impunctate and very glossy. The scutellum is impunctate except at the base. The apex of the elytra is 
finely transversely striated, this part being separated from the dise by a sharp curved depression. The pygidium 
is black, with a strong central carina and two conical tubercles. 
The name of I, nigripennis was applied by Dr. Schaum and Mr. Hope to two different insects, the deserip- 
tions 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. Schaum’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 Ist of July, 1839.
