and only specimen wanting. Thorax transverse, narrowed in 
front, sides distinctly angulated near base, surface entirely covered 
with deep round punctures, interstices sparingly clothed with short 
hairs. Elytra closely covered with strongly raised tubercles 
placed irregularly along the sides, arranged in longitudinal rows 
on the disc ; interstices with some deep punctures ; shoulders 
prominent, each in shape like an oblique, smooth, strongly raised 
tubercle. 
Length 6 mm. 
Hah. Ceylon. 
593. Nodostoma lefevrei, Jac. P. Z. S. 1887, p. 78. 
Dark fulvo-piceous ; base of femora fulvous. 
Head closely punctured on the vertex and sides ; clypeus sepa- 
rated from the face on each side by a deep fovea, anterior edge 
tridentate, surface scarcely perceptibly punctured; labrum fulvous ; 
antennae slender, third and following joints elongate. Thorax 
nearly three times as broad as long, sides strongly angulated near 
base, posterior angles produced into an acute tooth, anterior sulcus 
distinct ; surface very closely punctured, with some smooth raised 
spaces, irregularly distributed. 8cutellum nearly black. Elytra 
with deep basal depression, very strongly longitudinally costate on 
the inner disc, interstices regularly punctate-striate, sides trans- 
versely rugose and wrinkled, darker in colour than the sutural 
portion. Femora with a minute tooth, base pale fulvous. 
Length 5 mm.

Allied to N. tuberosum, but the thorax much more transverse 
and more finely punctured, the elytra costate and differently 
coloured. 
594. Nodostoma obscurum, sp. n. 
Piceous ; bases of the antennae and of the femora obscure fulvous. 
<y . Narrowly oblong. Head broad, convex at base, latter 
remotely and finely punctured, lower portion more closely and 
strongly punctate ; anterior edge of clypeus semicircularly emar- 
ginate ; labrum piceous ; antennae extending beyond the middle 
of the elytra, basal three joints fulvous, rest black. Thorax about 
half as broad again as long, sides strongly angulated behind the 
middle, surface very closely and finely punctured, anterior margin 
not preceded by a sulcus, posterior angles produced into a straight 
tooth. Seutellum smooth, apex subtruncate. Elytra oblong, 
strongly depressed at base, the latter raised; disc strongly punctate- 
striate ; shoulders very prominent, followed by two or three longi- 
tudinal costrn, their interstices much more strongly punctured than 
the others. Femora strongly incrassate, with a small tooth ; inter- 
mediate tibice strongly, posterior feebly, emarginate at apex. 
Prosternum much broader than long.
