the name a Ninus insignis Stâl (singalensis Bredd.) » is doubtless 

 some species of Cymoninus, probably subunicolor Bredd.( I) In the 

 generic description of ISimis Dtst. iiec STAL(riliynch.Brit. Ind.II, 

 p. 19 aiid 20) the claval suture is described as « not distinctly lon- 

 ger than scutellum », but it is, of course, much longer than it. What 

 he means is apparently the claval co^mnissuvc. In trying to decipher 

 the descriptions of this author it must be borne in mind that he in 

 his writings on Hemiptera uses the term claval suture promiscu- 

 ously hoth for the claval commissure and for the real claval suture, 

 although thèse two terms signify qui te différent things. He some- 

 times speaks of the claval « margin » without further spécification 

 or explanation and possibly in the sensé of claval suture, but he 

 does not use the term claval commissure, except in translations 

 frdm other authors, and apparently does not know the meaning of 

 it. — The genus Neoninus Dtst. is closely related to Cymoninus, but 

 the head is less transverse, the antennse are somewhat difîerently 

 constructed, and the basai part of the elytral costal margin is frin- 

 ged with long hairs as in Ninus. 



Ninus substylatus n. sp.~ In N. K. Bornéo (Sandakan) Prof. 

 C. F. Baker bas found a species which in colouring and size is so 

 similar to N. insignis that itis only necessary to give the distinctive 

 characters.

(1| In Kis trauslation of the descriptioa of this species Distant says : « ocelli 



less remote from each other than from eyes » (which would be a character of 



iSinus), whereas Breddin says : die Nebenaugeu von eiua'uder w«nig weiter als 



vou den Augeu eulfernt (ocelli little moi'e remote from each other thau 



rom eyes).
