The above synonymy is given on the authority of Mr. Eeitter 

 {I. c.) ; it stands, however, in need of confirmation, for Mot- 

 schoulsky's figure and description, both of them bad, indicate an 

 insect of more slender form, with thinner and longer antennae 

 than the species of MacTilotes known to me possess. Mr. Eeitter 

 does not state on what evidence he bases the identification, which 

 is given without any doubt on his part. Although Motschoulsky 

 placed his genus in the Lathridiidae — where also it is located in 

 the Munich Catalogue — it should, from the evidence he himself 

 supplies, have been placed in the Colydiidae near Bothrideres. 

 The Motschulskyian genus was based on an insect from the 

 mountain Nuwara EUia in Ceylon, but thespecies appears unknown 

 to me : at least I find it impossible to believe that his figure and 

 description were taken from- the species found by Mr. Lewis in 

 Ceylon, which I therefore describe as new. 



Eeottlatheis cogkatus, n. sp, 



Piceus, opacus ; prothorace quadricostato, costis posterius a fissura 

 transversa profunde divisis ; elytris sulcatis, interstitiis argute elevatis, et 

 subtilissime crenatis. Long. 3-4 millim. 



This species is extremely closely allied to the Japanese E. cos- 

 tatus, so that when the upper side only is examined, the two 

 appear to be conspecific, but beneath there are some important 

 differences between the two. In E. costatus there proceeds from 

 the intermediate coxal cavity a very short raised line extending 

 backwards on the metasternum ; while in E. cognatus this line 

 extends all the length of the metasternum (being, however, 

 obsolete in the middle), and reaches the hind coxa. In E. costatus 

 the whole length of the metasternum is covered with a dense, 

 very coarse punctuation ; but in E. cognatus this sculpture is
