the edge, but it is continued behind the head somewhat away 
from the edge; round the anterior angles there is also a 
marginal stria; the elytra, the oblique humeral stria is fine 
but clearly marked, the other humeral stria are wanting, 
dorsal striz 1-3 complete, the second at the base for one third 
of its length turns inward towards the third, 4-5 are apical 
and rudimentary ; the propygidium is transversely punctured ; 
the pygidium wholly and more densely punctured ; the punc- 
tures on both appear under the microscope to be obscurely 
ocellate, outer margin of the pygidium is slightly raised; the 
prosternum is without strie; the mesosternum is marginate 
and feebly sinuous behind the prosternal keel; the anterior 
tibia are 4-dentate. 
The form of this species is similar to P. carolinum, Payk., 
P. sincerum, Sch., and others. It is only the second species 
of Platysoma known with maculate elytra. 
Hab. Palembang, Sumatra. 
Cypturus bengalensis, sp. n. 
Oyalis, oblongus, convexus, eneo-niger ; fronte rugoso-punctata ; 
elytris, striis 1-3 integris, 4-5 basi evanescentibus, suturali 
utrinque vix abbreyiata ; prosterno stria marginali antice acumi- 
nata. 
L, 6 mill: 
Oval, oblong, convex, brassy black, somewhat shining and 
very similar to C. @nescens, Kiy., in general sculpture ; but it 
differs distinctly in being larger, the head more coarsely and 
rugosely punctate ; the elytral striz are less clear, owing to 
their interstices being very densely granulate-punctate (not 
simply punctulate as in C. @nescens), the prosternal keel 
anteriorly is acuminate (not arcuate), the mesosternum is 
sometimes distinctly punctulate, and the female has two rather 
small rugose lobe-shaped impressions close together behind 
the middle of the disk of the pygidium, and on either side of 
them, but nearer the apex, is a transverse rugose excavation ; 
the two excavations are somewhat larger than the two im- 
pressions. In C. enescens 2 the pygidium has a smooth 
median carina, and on either side of it are two large and deep 
rugose impressions which occupy the whole area of the disk. 
Hab. Bengal. 
I am indebted to Herr Hilmar v. Schénfeldt for fourteen 
examples of this species. C. canescens is also reported as 
occurring mm Bengal, but all the specimens in my collection 
are from the Nilgiri Hills and Ceylon.
