COLTDIIDJE OBTAINED IN CEYLON. 123 



Under surface dull, not distinctly punctured. Tibiae slender, 

 almost linear, witli minute acute apical outer angle. 



Dikoya ; two examples. 



This little insect much resembles Xuthia niponipa, Lewis ; but 

 the three-jointed club of the antennae requires that it should be 

 placed in Ithris ; indeed, in many respects it agrees closely with 

 Mr. Pascoe's description of I. decisa, though differing in several 

 other particulars. 



Metopiestes tubitltjs, n. sp. (Plate VI. fig. 6.) 

 Subcylindricus, nigricans, baud nitidus ; antennis, tibiis tarsisque rufes- 



centibus ; fronte plana, anterius pubescente ; protborace crebre fortiter 



punctate ; elytris costatis. Long. 4 milUm. 



Head flattened in front, the anterior part occupied by a patch 

 of flavescent, erect, fine hair. Thorax yery convex transversely, 

 just perceptibly narrowed behind, slightly longer than broad, the 

 front angles rounded, not at all prominent ; the surface very 

 dull, but with a silky appearance, and covered with moderately 

 coarse and close punctures. Elytra each with five conspicuous 

 ribs, one of wb.ich is at the suture, and this, by prolongation out- 

 wards at the extremity, connects witli the outer rib, thus forming 

 an apical margin ; the interstices bear on the middle a rather 

 close irregular punctuation, which does not extend to the base, 

 apex, or outside ; the base of the elytra is lobed on each side 

 near the scutellum. Under surface but little punctate. Meta- 

 sternum very elongate. 



Bogawantalawa, 8th March, 1882. 



This species is, I have little doubt, allied to M. erosus from 

 Batchian. The pubescent front exists on each of the two examples 

 found ; but may be a sexual character. The genus is somewhat 

 difficult to locate, and would perhaps best go into Horn's group 

 Deretaphrini ; thougli the front coxae appear to be contiguous, 

 they are, in fact, separated by a very narrow process, and the hind 

 coxae are not very widely distant. 



Mecedanops oenamentalis. 



Mecedanops ornamentalis, Reitter, Deutsch. ent, Zeit. 1878, p. 120. 



Ceylon, Reitter. This is unknown to me; Mr. Lewis met 

 with a specimen wliich, from his account of it, might probably 

 be this insect, but, unfortunately, lost it by an accident in 

 mounting.
