M. Petri Semenow of St. Petersburg has communicated to 

 me a MS. description of Trigonotoma violacea Cast., by the late 

 M. Tschitscherine, from which I have been able to determine it 

 without doubt as the Sydney form of N. Jletcheri SI. M. Tschit- 

 scherine's note indicated that one of the specimens before him 

 (belonging to the Paris Museum) was ticketed " Sydney." My 

 description of N. Jletcheri was founded on the form found at 

 Springwood, which has the head and prothorax of a cupreous 

 colour, elytra with a dark cupi eous tinge. I believe that it will 

 be found advantageous for collectors to retain this name for the 

 mountain form or variety of X. violaceus Cast.
