COLTDIID^ OBTAINED IN CEYLON. 129 



Ptcnomerus CEASSICOENIS. 



Penthelispa crassicornis, Reitter, Stett. ent. Zeit. xxxviii. p. 349. 



Dikoya ; a few examples. 



Ptcnomeeits nitibicollis. 



Penthelispa nitidicoUis, Reitter, Stett. ent. Zeit. xxxviii. p. 353. 



Dikoya ; a few examples. 



Ptcnomerus distans, n. sp. (Plate VI. fig. 8.) 

 Minor, subdepressus, rufulus, nitidus ; prothorace fortiter punctato, 

 tenuiter marginato ; elytris striatis, striis fere simplicibus, interstitiis latis, 

 irapunctatis ; antennis 10-articulatis. Long. 2-2j millim. 



Antennse short, rather slender, with a rather slender acuminate 

 club, which has lost all trace of a division into two joints. Eyes 

 but little prominent : head bifoveolate. Thorax longer than 

 broad, coarsely punctate, the interstices broad and shining ; it is 

 distinctly narrower than the elytra, scarcely narrowed behind, 

 the front angles are rounded, and the lateral margin fine and in- 

 conspicuous ; the strise on the elytra show only faint traces of 

 sculpture, and the interstices are quite impunctate. Metasternum 

 elongate ; tarsi short. 



This is a yery distinct little insect; but I canuot find any 

 character to warrant its separation from Pycnomerus. 



Dikoya and Bogawantalawa ; eight or nine specimens. 



EcTOMiCRiis SETOSUs, n. sp. 



Oblongus, rufus, setulis erectis'tenuibus minus sparsim adspersus ; pro- 

 thorace dense fortiterque punctato ; elytris seriatim fortiter punctatis, in- 

 terstitiis subconvexis. Long. 2\ millim. 



Antennal club large, pubescent except at the base ; eyes very 

 convex. Thorax r-ather broader than long, truncate in front, sides 

 very finely margined, slightly narrowed near the front angles, the 

 surface coarsely and closely punctate. Elytra with regular series 

 of coarse punctures, the interstices convex, impunctate. 



This species in form and appearance is not so diff'erent from 

 the genus Cerylon as the Japanese E. rugicollis is ; but, on the 

 other hand, the mesosternal cavity for the reception of the pro- 

 sternal process is more developed than in the other Ectomicri, and 

 this separates it completely from Cerylon. 



Dikoya and Bogawantalawa ; a few examples. 



EcTOMiCEUS APEE, n. sp. (Plate VI. fig. 11.) 



Oblongo-ovalis, convexus, piceorrufus, opacus, setis elongatis, tenuis-
