1887.] PHYTOPHAGOUS COLEOPTERA OF CEYLON. 79 



A single specimen (coll. Jacoby). 



N. lefevrei differs from N. tuberosum in the much more transversely- 

 shaped and finely punctured thorax, the strongly costate elytra and 

 their coloration. 



NODOSTOMA CLYPEATUM, Sp. nOV. 



Pale testaceous; apical joints of the antennae fuscous; clypeus 

 strongly punctured ; thorax angulate below the middle, strongly 

 punctured at the sides only ; elytra with basal depression, the latter 

 distinctly, rest of the disk nearly obsoletely, punctured. 



Length 1 line. 



Head nearly impunctate at the vertex ; the epistome strongly but 

 very remotely [)unctured, not separated from the front ; the space 

 above the insertion of the antennas obliquely grooved. Antennae 

 slender, nearly as long as the body, testaceous, the three or four 

 terminal joints fuscous or black. Thorax twice as broad as long, 

 strongly narrowed in front, the sides distinctly angulate near the 

 base, surface without an anterior groove, strongly punctured at the 

 sides only, the middle of the disk with a iev; fine punctures only. 

 Elytra with a very distinct subbasilar depression, the base itself with 

 a few remotely placed punctures arranged in hues which extend 

 more or less distinctly to the middle; below the latter the punc- 

 tuation is almost entirely wanting ; femora with a minute snine. 



Galle. ^ 



Principally distinguished by the nearly impunctate vertex, the 

 strongly punctured epistome and sides of the thorax, in connection 

 with its general small size ; the absence of a transverse anterior 

 groove at the thorax will further assist in the recognition of 

 iVi clypeatum. 



NoDOSTOMA LONGICORNE, Sp. nOV. 



Fulvous ; legs testaceous, the knees obscure piceous ; antennae 

 as long as the body ; thorax very finely punctured, angulate behind 

 the middle ; elytra strongly punctate-striate, with basal depression, 

 the lateral margins anteriorly black. 



Var. Elytra entirely fulvous. 



Length 2-2g lines. 



Head finely and rather remotely punctured ; the epistome separated 

 from the front by a slight transverse depression, with a few deep 

 punctures ; palpi testaceous. Antennae as long as, or slightly lono-er 

 than, the body, fulvous, the apical joint darker, the fourth joint rather 

 longer than the third. Thorax transverse, strongly narrowed in front, 

 the sides distinctly angulate near the base, the surface with a deep and 

 punctured transverse sulcation near the anterior margin, very finely 

 and ratiier remotely punctured, the lateral margin narrowly piceous. 

 Elytra not broader at the base than the thorax, with a deep subbasal 

 depression, very strongly and deeply punctate-striate anteriorly, more 

 finely towards the apices, the interstices slightly convex, more dis- 

 tinctly so at the sides, the lateral margin anteriorly rather broadly 

 piceous or black, this colour extending slightly across the elytral
