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 ro\vs 

 on the disc ; interstices with some deep punctures ; shoulders 

 prominent, each in shape like an oblique, smooth, strongly raised 

 tubercle. 



Lenf/th 6 mm. 



Hab. 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 t'ovea, 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. Scutellurn 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. 



Hab. Ceylon. 



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 antennas and of the femora obscure fulvous. 



cJ . 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- 

 giuate ; labrum piceous ; antenme 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. Scutellum smooth, apex subtruncate. Elytra oblong, 

 strongly depressed at base, the latter raised ; disc strongly punctate- 

 striate ; shoulders very prominent, followed by two or thi'ee longi- 

 tudinal costa3, their interstices much more strongly punctured than 

 the others. Femora strongly incrassate, with a small tooth ; inter- 

 mediate tibiae strongly, posterior feebly, emarginate at apex.. 

 Prosternum much broader than long.
