OF NEW ZEALAND. 347 



or less convex, rounded anteriorly, the edges of forehead carinated. 

 Antenna ten-jointed, moderate; the basal joint thick, sub-ovate, second 

 much shorter, third slender, longer than second, joints four to seven 

 shorter, and decreasing in length ; eighth to tenth forming a club, its 

 first and second joints sub-globular, the third short, oval, and often 

 terminated by a small sponge-like appendage. Prothorax convex, mar- 

 gined laterally, and sometimes at its base. Scutellum triangular or 

 rounded. Elytra convex, of variable length. Legs moderate; femora 

 wide and compressed ; tibia slender, their external apex often pointed ; 

 tarsi with four joints, the three first small, equal. 



630. 0. undulatUS, n.s. Oblong, transversely convex ; fuscous, 

 variegated with testaceous ; the palpi, basal joints of antennae and legs 

 reddish. Antenna not so long as head and thorax ; basal joint stout, 

 joints two to eight slender; ninth to eleventh forming, a distinct 

 loosely articulated club, the ninth and tenth considerably larger than 

 their predecessors, transverse ; the eleventh rounded. Last joint of 

 palpi ovate, robust. The head is rather closely and somewhat rugosely 

 punctured, the sides in front of the eyes carinated, but only slightly 

 elevated. Eyes moderately prominent, coarsely facetted. Thorax 

 about as long as broad, obtusely produced in front, the base sinuated 

 beyond the middle, with distinct lateral rims and transversely convex ; 

 the sides are nearly straight, yet a little rounded and narrowed 

 anteriorly ; its surface is finely rugosely and closely punctured ; the 

 sides, a basal spot, and a large triangular space in front, are testaceous, 

 the disc fuscous ; and the clothing consists of fine short cinereous hairs ; 

 there is an indistinct dorsal line, which is a little elevated near the base. 

 Elytra oblong, finely margined, the base slightly emarginated, the sides 

 a little rounded, and widest behind the middle ; their sculpture is very 

 similar to that of the thorax, with very short cinereous hairs proceeding 

 from the punctures ; the ground colour is fuscous, with an elongate 

 humeral spot, a medial, strongly flexuous fascia, and an apical spot 

 sending forth a lunule towards the suture, and the suture between the 

 latter and fascia, testaceous ; these markings give the elytra an undu- 

 lated appearance.

I found this species in several localities ; but I have not seen any 

 specimens of this or the nine following species from other sources. 



631. C. assimilis, n.s. Very similar to the preceding, yet quite 

 distinct, being much smaller and narrower ; the colouration and 

 markings of the thorax and elytra are the same as in C. undulatus, but 

 the head is piceous, finely ridged, and the clothing of the body is more 

 obvious, consisting of whitish scale-like hairs, which, however, are absent 

 on the head. The form of the prothorax is different, its widest part 

 being in front of the middle ; and the elytra are almost parallel, so that 

 the outline of the insect is quite dissimilar to C. undulatus, the latter 

 having the elytra elongate-oblong-ovate, and not at all parallel-sided.
