COLTDIID^ OBTAINED IN CEYLON. ]19 



COXELUS ? 



Coxelus ? unicolor, Motsch. Bull. Mosc. 1863, ii. p. 503. 



The description apparently indicates an insect unknown to me. 

 Motschoulsky does not state any reason for doubting that the 

 species belongs to Coxelus, but it is highly improbable that it does. 



Taephiosoma. 



Tarphiosoma, Woll.Journ. Ent. i. April* 1862, p. 373; Pascoe, Journ. 

 of Ent. ii. p. 138. 



Motschoulsky's genus Tarphisoma is not the same as this ; but 

 will be found characterized in this paper under the name of J^eo- 

 platus. Mr. WoUaston's surmise (Trans. Ent. Soc. Lond. 1873, 

 p. 3, note) that the two names applied to the same form proves 

 therefore not to be correct. 



Taephiosoma echinatum. 



Tarphiosoma echinatum, Woll. Trans. Ent. Soc. Lond. 1873, p. 3. 



PTarphius? pilosus, Motsch. Bull. Mosc. 1863, p. 506, 



A good series of this species was secured by Mr. Lewis. Al- 

 though Motschoulsky's description appears to me to characterize 

 the insect subsequently described by "Wollaston, I have not at 

 present thought right to adopt his name, the identification not 

 being sufficiently satisfactory. 



Dikoya ; nineteen specimens. 



Taephiosoma lueidum, n. sp. 



Sat convexum, nigrum, opacum, hie inde minus conspicue fusco-tomen- 

 tosum, setulis erectis parce adspersum ; prothorace brevi, angulis anteri- 

 oribus longe productis, acutissimis, lateribus valde curvatis, posterius sat 

 angustatis ; antennis pedibusque piceis, tarsis rufis. Long. 4 milUm, 



This is very closely allied to T. echinatum, "Woll., but is of 

 darker and more uniform colour, the elytra being not variegate, 

 and destitute of the patches of black squamosity that exist in T. 

 echinatum ; the after body is less abbreviate, the metasternum 

 a little longer, and the upright setae are shorter and stouter, not 

 at all acuminate. 



Dikoya ; nine examples. 



Neoplatus. 



Tarphisoma, Motsch. Bull. Mosc. 1863, i. p. 504 ; op. cit. 1861, i. Tab. 



ix. f. 32. 



As the name Tarphisoma is practically the same as Tarphiosoma,
