218 PENTATOMID.^. 



Division NEZARIA. 



In the yezaria the pronotal angles are not prockiced hut are 

 rounded or subprominent, thus differing from the previous division. 

 The abdomen is always more or less distinctly spined at base, and 

 the head is moderately narrowed to apex and more or less sinuated 

 at the lateral margins. 



The genus Catacanthvs, which is here included, is not strictly 

 homogeneous, though agreeing in the divisional characters. In 

 arranging the whole of the subfamily, I should place it in a group 

 of genera not found in the fauna of British India, but consider it 

 inexpedient to here make a division for a single geuus.
