Sphaeroderma flavoplagiata n. sp. 
Subhaemispherical, dark fulvous, antennæ (the basal joints 
excepted) black, thorax finely pnnctured, elytra strongly punctate- 
striate, the interstices finely panctured, piceous, a large subtrian- 
gular patch from the base to the middle, flavous. 
Length 2 lines. | 
Very convex, slightly narrowed posteriorly, the head impunc- 
tate, fulvous, the eyes very large, occupying the entire sides, frontal 
tubercles rather small, clypeus deflexed, its anterior edge straight, 
antennæ extending slightly beyond the base of the elytra, black, 
the lower three joints fulvous, the basal joint rather elongate, the 
second and third joint equal, short, the rest more elongate, nearly 
equal, thorax twice as broad as long, strongly widened at the 
middle, the sides slightly rounded, with a narrow reflexed margin, 
anterior angles obliquely rounded, posterior margin sinuate at the 
sides, its median lobe broadly rounded and produced, the surface 
very minutely punctured, the punctures nearly obsolete anteriorly, 
more distinct and larger near the base, scutellum fulvous, elytra 
regularly and strongly punctate-striate, the interstices everywhere 
finely punctured, the colour piceous, interrupted by a large pale 
flavous patch, which occupies the entire anterior half, extending 
below the middle, but not touching either margins, towards the 
sides the patch is gradually narrowed, tibiæ rather deeply chanel- 
led, prosternum broad, subquadrate. 
ab. Toungoo. 
The large flavous elytral patch principally distinguishes this 
species, the elytral epipleuræ are deeply concave and also flavous ; 
S, ornata Baly has differently coloured antennæ and two elytral 
flavous spots on each. Argopus Fortunei Baly also resembles the 
present species but is larger, the clypeus is rugose, the antennæ are 
longer and the sculpturing of the elytra, as well as their colour, 
is different. 
Erystus(?) indicus n. sp. 
Fulvous, the breast and the abdomen piceous, head and thorax 
impunctate, elytra extremely finely and closely punctured, nearly 
black. 
Length 1 line. 
Head broader than long, the frontal elevations and the carina 
entirely obsolete, clypeus narrowly raised, transverse, palpi as 
well as the labrum fulvous, antennæ extending to the middle of 
the elytra, rather robust, fulvous, the terminal four joints black, 
basal joint rather long and thick, the following three joints equal,
