Rhiobia exemnlificata Uisr. — The genus Ihnuiduca Djst. 

 (Apriri918) is identical witli Rhiobia Bemgr. (March 1918). The 

 above species is allied to Rh. prœceiis Behgr., but is clearly speci- 

 Pically distinct from it by laterally more roiinded pronotum and 

 some other characters. 



Ninus insignis Stàl, — I bave now received this widely dis- 

 persed insect also from Guam (the original localily), Bornéo, and 

 Singapore. The colouring is somewhat variable, the head, prono- 

 tum and scutellum being in quite fresh spécimens in part covered 

 with a pale greyish bloom or tiiiu incrustation, StAl's description 

 is correct, but his figure of the head somewhat inaccurate and mis- 

 leading. Yet since 1907, when Breddin redescribed the genus. it is 

 easily recognizable, and in Philipp-Journ. Se. XIII, p. 64 I bave 

 given some additional generic characters. Distant's translation 

 (from Breddin) of its principal characters is correct (« eyes dis- 

 tinctly stalked, projecting obliquely in front and outwardly ; head 

 and eyes as broad as pronotum between the slionlders ; costal bor- 

 ders of tegmina parallel in their basai fiftli, outwardly with a long 

 and thick white fringe, then rather strongly widened and distinctly 

 rounded » ), but he déclares that the characters by wliich Cymoni- 

 mis Bredd. (Ninus Dist. nec. Stâl) is distinguislied from Ninns 

 Stâl « appear to be of scarcely subgeneric value ». N'evertheless he 

 redescribes the same Ninus insignis Stâl (singalensis Bkedd. ) as a 

 new genus and species under the name Ossiiiat/a ceiiUviica, paying 

 no attention to Bkeddin's description ami oniitting from his owii 

 description some important characters, but annexing a good and 

 accurate figure of the insect. The species recorded by Distant
