12 16. A. Stewarti, n.s. Obovatc, bul lilllc arched, clothed with 

 short, decumbent, dark-grey liairs, causing tlie insect to appear rather 

 dull, though in reality glossy black, with pilchy-rcd legs and infuscate- 

 red antennce. 



Head with linear impressions and fine punctures ; the suture of the 

 epistome indistinct. Prothorax transversal, very obtusely lobed in the 

 middle, and obliquely truncated towards the posterior angles ; its surface 

 bearing excessively minute punctures. Scutelliim triangular, finely punc- 

 tulated. Elytra obovatc, slightly convex ; each with about six very fine 

 strice, and densely sculptured with transverse, excessively finely j^unctured, 

 linear impressions. Antcniice pubescent, with oblong articulations, their 

 fourth joint rather longer than the fifth ; eleventh about as long as the 

 tenth, obtusely rounded apically. Tibice elongate-triangular, their spurs 

 short ; posterior tarsi 5-articulate, the basal joint longest, fourth entire 

 and but little abbreviated ; claivs small, thickened at the base. 



Length, i.V lines; breadth, -5. 



My specimen was discovered near Wellington, by Wr. P. Stewart, in 

 whose honor the species is named. 



1 2 17. A. tGllGr, «"f. Subdcprcssed, obovatc, soft, densely covered 

 with short griseous hairs ; head antl thorax somewhat rufescent ; elytra 

 testaceous, shining. 



Head covered with irregular linear impressions ; prothorax and elytra 

 similarly sculptured, the latter more coarsely. Under-side closely sculp- 

 tured and pubescent ; legs similarly impressed and clothed, but with the 

 cilice at the extremity of the tibia; and tarsal joints black. The five seg- 

 ments of the abdo?ne?i about equal. 



Length, i\ lines; breadth, |-. 



A slender insect, difiicult to manipulate, and much distorted by being 

 sent in paper. This sj^ccies also was found by ]\Ir. P. Stewart, near 

 Wellington. The scutellum is invisible, but the suture of the epistome is 

 distinct.

1 2 18. C. ObliquisignatUS, Schccnherr. Colour dark fuscous; 

 legs, tarsi, and antenuLU reddish. 



Prothorax broader than long, widest in the middle, behind which the 

 sides are straight, and narrowed anteriorly ; its front margin is rufescent, 

 and it bears a feeble dorsal groove. Elytra oblong, humeral angles 

 oblique, sides parallel or nearly so, narrowed behind ; on the disc the 

 stria; are quite obsolete, with somewhat quadrate punctures ; the third and 

 fifth interstices are very slightly elevatetl throughout, and at the summit 

 of the posterior slope obtusely tubercular. 



On comparing this with C. ohUqutis it will be observed that it is much 

 more obscurely coloured, though clothed similarly ; the elytra are less 

 convex, with less pronounced apical sculpture ; the thorax is shorter and 

 differently shaped ; and the insect itself is larger. In both species the 

 scutellum is nude and shining. 



I have not seen the original diagnosis : the above corresponds with a
