58 MR. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA. [Jan, 3, 
black spot near the scutellum and another broad band of the same 
colour, the anterior part of which is greatly narrowed and concave 
at its inner margin; this band does not extend quite to the lateral 
margin or the apex. Underside and femora testaceous ; tibize and 
tarsi black,

14, MALACOSOMA FLAVOMARGINATUM, Sp. Nov. 
Elongate, testaceous. Head and thorax fulvous; elytra closely 
punctured, blackish blue, the lateral and sutural margins flavous. 
Length 3 lines. 
Hab. South Africa. 
Head convex, closely punctured. Antenne half the length of the 
body, black, first three joints flavous. Thorax of the same shape as in 
M. quadrimaculatum, its surface distinctly but less closely punctured. 
Scutellum flavous. Elytra very closely and rather strongly punc- 
tured, black with a bluish tint, the sutural and lateral margins, as 
well as the apex, narrowly flayous. Underside and legs of the same 
colour ; tarsi piceous.

15. GONIOPLEURA BASALIS, Sp. Noy. 
Elongate, convex, rufous. Thorax finely punctured, its sides tri- 
dentate; elytra finely pubescent, metallic green or blue, the base 
more or less broadly rufous. 
Length 7 lines. 
Hab. Sumatra. 
Head finely and closely puuctured. Clypeus slightly transversely 
depressed, its anterior margin deeply concave and bidentate. Apex 
of jaws black. Antenne light fulvous, extending to one third the 
length of the body. Thorax subquadrate, punctured like the head ; 
each lateral margin produced at the middle into a biangulate flat 
protuberance preceded by a small tooth, from which an oblique 
depression extends across the disk towards the base. Scutellum 
rufous. Elytra convex and parallel, closely and rather more strongly 
punctured than the thorax, and covered, especially towards the apex, 
with whitish pubescence ; metallic green or blue, with a more or less 
broad rufous transverse band at the base. Underside and legs 
rufous.

From G. viridipennis, Clark, to which the present species bears a 
great resemblance, it may be distinguished by the dentate and 
angulate lateral thoracic margin, which in Clark’s species consists of 
a single tooth only, while here it is followed by an almost square- 
shaped broad angular protuberance. The rufous basal margin of 
the elytra varies in width, but is constant. This species forms the 
fourth of the genus Goniopleura,
