 Creek, N.S.W. (The Author). 



Five specimens of this pretty little insect differ only in colour, 

 the Acacia Creek specimen being the most brilliant, the head and 

 jironotum being blue-green, the elytra purple at suture, then blue, 

 green, gold, purple, blue, and gold (on sides), succeeding one 

 another. Types in the Author's Coll. 



Menephilus rectibasis, n.sp. 

 Elongate, parallel, nitid-black above and beneath, tarsi and 

 antennae red (tibiae sometimes reddish). 



Head minutely punctate on epistoma, more coarsely so on fore- 

 head, the former surface extended backward more than usual, and 

 defined by arcuate depression, eye-sockets more deeply hollowed 

 than in M. Sydneyanus Blkb., the antennae shorter and less en- 

 larged apically than in that species. Prothorax 2-5x3 mm., 

 apex bisinuate, advanced in the middle, the anterior angles acute 

 and strongly advanced, sides feebly arcuate, narrowed apically, 

 almost straight on posterior two-thirds, base truncate, posterior 

 angles sharply rectangular, lateral margins raised, distinctly sul- 

 cate within, basal border narrow but clearly defined, disc densely 

 and finely punctate, without central line, and with two small and 

 inconspicuous basal foveas. Scutellum transversely oval. Elytra 

 scarcely, or very slightl}^, wider than prothorax at base and more 

 than twice as long, shoulders rather sharply rectangular, sides 

 parallel, less convex than M. Sydneyanas Blkb., striate-punctate, 

 the seriate punctures small and closely placed in deep striae, inter-
