a)jex, very slightly ampliated on the sides, narrowed behind the 

 middle, with the posterior angles acute and recurved. There is 

 a very minute puncturation on the upper surface, the median 

 line is very slightly marked, and the grooves on each side of the 

 base are broadly and deeply impressed, but do not extend forward 

 more than one-third of the length. The elytra are broader than 

 the thorax and a little over twice the length, flat, striate, sub- 

 nitid, rounded at the humeral angles, and truncate at the apex. 

 The under surface and legs are of a pitchy brown. 



Length, 4 lines. 



16. ZUPHIUM FlTZROYENSE, n.Sp. 



This species is very like Z. Plndan, as indeed are all the species 

 of the genus known to me ; it differs in being almost entirely of 

 a reddish colour, excepting the elytra, which are of an opaque 

 black ; the head is more impressed in front, the thorax is more 

 cordiform, legs flat, and less acute and recurved at the posterior 

 angles. The elytra are densely and very minutely punctate, and 

 the striae are somewhat faint. The antennae and legs are longer 

 and entirely red. 



Length, 4-^ lines.

This is altogether a smaller insect than those from the East 

 Coast, and may be another species, but I cannot make out any 

 good specific diflference.

 Very like G. sulcatum, Macleay; black, subnitid, labrum smooth, 

 excepting a few punctures on the apex, a little broader than the
