Leptocorisa Bengalensis, Westwood, L. acuta, Thuribcrg, 

 L. varicornis, Fabricus ; Munju vandu of the Tamil 

 people of Tinnevelly ; Gandi of Assam. About January 

 1886, Mr. Lee-Warner, Collector of the Tinnevelly district 

 of the Madras Presidency, brought to the notice of the 

 Director of Eevenue Settlement, that 50 per cent, of the 

 rice crops nearly throughout the Srivilliputur taluk had 

 been injured by the Leptocorisa Bengalensis. This- 

 insect belongs to the family Coreidse of the order Ehyn- 

 chota, the vast majority of the members of which live 

 upon the juices of plants, a few only, such as the common 

 bed-bug, attacking animals. This bug was described in 

 1837 by Professor Westwood, in his Catalogue of Hemi- 

 ptera in the Collection of the Eev. F. W. Hope. If the 

 synonyms prove all to refer to one and the same species, 

 it will be found to range, under slight variations of form, 

 from India and Ceylon, through Burma and the Malay 

 countries, to Australia, wherein it affects low-lying lands 

 suited to rice cultivation, only occasionally creeping a 

 short distance up contiguous hill-sides. W.-M. 



Leptura. A small species of this insect genus has 

 been observed in numbers in the logs of the harder woods 

 of Kamaon and Garhwal. A larger species has also been 

 seen. The genus belongs to the family Lougicornes, 

 order Coleoptera. R. Thompson.
