1887.] PHYTOPHAGOUS COLEOPTER4 OF CEYLON, 11 



narrowly black, the latter accompanied by a vow of deep punctures. 

 Legs testaceous; all the femora armed with a small toolh. 



Dikoya, 



Amongst the many described species o^ Nodostoma, N. bipunctatum 

 may be known by the very short and transverse tlioras in connection 

 with the coloration. 



NODOSTOMA IMPRESSIPENNE, Sp. nOV. 



Entirely testaceous ; the last seven joints of the antennae black ; 

 head and thorax distantly punctured ; elytra with a deep basal 

 depression, the latter strongly, the rest finely punctate-striate ; legs 

 very long. 



Length 1| line. 



Head strongly but very remotely punctured ; the epistome not 

 separated from the face. Antennae slender, scarcely shorter than the 

 body, the four lower joints testaceous, the rest black, the third and 

 fourth joints slender, equal. Tliorax not more than twice as broad 

 as long, the sides angulate near the base, obliquely narrowed 

 towards the apex and slightly rounded before the middle ; the surface 

 with a transverse groove in front of the anterior margin, very 

 strongly but remotely punctured. Elytra narrowed posteriorly, with 

 a deep transverse depression below the base, testaceous, the sutural 

 and lateral margin narrowly fulvous ; the punctuation deep within 

 the depression, very fine at the rest of the surface ; there is also a 

 row of deep punctures placed close to the lateral margin and below 

 the shoulders ; underside and the legs testaceous ; all the femora 

 armed with a small tooth. 



Galle. 



Closely allied to N. fairmairei, but the thorax is longer, less 

 transverse, and more strongly and remotely punctured, and the legs 

 are much longer in N. impressipenne. 



NoDOSTOMA LEWISI, Sp. nOV. 



Testaceous or fulvous ; the apical joints of the antennae black ; 

 head remotely, thorax very closely and strongly punctured, sub- 

 angulate near the base ; elytra nearly impunctate below the middle, 

 the sutural and the lateral margins black. 



Var. The disk of the thorax more or less piceous. 



Length 1-1 1 line. 



Head with a few punctures ; the epistome more strongly and 

 closely punctured, not separated from the front. Antennae two 

 thirds the length of the body, the four lower and the base of the 

 following joints testaceous, the terminal joints black. Thorax 

 transverse, strongly narrowed in front, the sides distinctly angulate 

 near the base, the surface very strongly or subrugosely punctured. 

 Elytra with a distinct depression directly below the base, the latter 

 distinctly punctured, the punctuation gradually disappearing below 

 the depression ; the lateral margin narrowly, the sutural more 

 broadly, black, this colour widened in some specimens towards the 

 base at the suture. Legs with a very minute tooth. 



Dikoya.
