A pair taken in coitu by Mr. Lefroy at Pasa, Bengal, in 

 June. 



The female is very nenr fusa'pennis, Sm., but in that insect 

 the median segment is abruptly truncati^, leaving a well- 

 d( fined apical margin, which is not the case in petiolata ; the 

 niesonotuni also is much more strongly punctured in fusci-

 the same species.
