Fern. — Head, including the eyes, black ; the face clothed with fer- 

 ruginous down ; epicraniura impressed with a longitudinal sulcus, 

 which is very deep between the eyes ; the eyes are moderately large 

 and reniform, the lower or cheek lobe being the largest ; the face has 

 a large and deep depression occupymg the basal or upper portion of 

 the clypeus ; the first and second joints of the antennae alone are 

 present : prothorax black, clothed with ferruginous down, without 

 any trace of that central black velvety vitta which obtains in the 

 females of other described species ; the anterior portion of the pro- 

 thorax is smooth and somewhat ring-like ; the rest of the dorsal sur- 

 face uneven and tuberculated on each side ; it has two obtuse tu- 

 bercles : presternum produced between the procoxse into two short 

 incurved, backward-cUrected processes which approximate at their 

 apices, leaving an apertvire through which the point of a needle may 

 be passed : scutellum semicircular, clothed with ferruginous, with 

 the exception of the margin, which is glabrous : elytra ferruginous 

 and clothed with ferruginous down, wide at the base, narrowing to 

 the apex and then truncate, the angles of the trmicature being ob- 

 tuse ; the elytra are carinated, each having five caringe ; the first is 

 very short and nearly obtuse ; it commences near the scutellum and 

 ceases before it has reached a third of the length of the elytron ; the 

 second and third commence near the base of the wing and unite in 

 the apical area ; the third and fourth commence almost together just 

 below the humeral angle, and unite in the apical area ; the two pairs 

 are also united, and below their miion several other raised anasto- 

 mosing lines form a kind of network : the abdomen and legs are black, 

 with a short hairy pubescence ; metatibise with two distinct apical 

 spines. 



Hab. Australia. A single specimen of the female, taken by Mr. 

 Ince, R.N., in that gentleman's cabinet. 



Perhaps I may be permitted to avail myself of the opportunity of 

 stating that I am assiduously engaged in the preparation of a de- 

 scriptive list of the longicorn Coleoptera of our Australian colonies, 

 and that I shall feel deeply indebted to any members of the Zoological 

 Society who would kindly assist me by the communication of speci- 

 mens. As the extent and value of her colonies have always been a 

 distinguishing character of Great Britain, so I think should the in- 

 dustry of her sons take precedence of other nations in making known 

 to the world the abundant riches of those colonies in the field of 

 Natural History.
