the clypeus. The thorax is broader than long, ahnost truncate 

 in front, and very much rounded away behind ; the medial line 

 is deep with fine transverse wrinkles on each side of it. The 

 elytra taken together are nearly oval, and are marked with a few 

 broad longitudinal depressions, crossed by a number of deeper 

 transverse and irregular ones, giving a very uneven appearance ; 

 near each lateral margin a ridge extends from the base to the 

 apex, between these ridges the elytra are flat, but the space 

 between each ridge and the side is almost vertical, and contains a 

 row of large punctures. The fore tibias are tridentate. 



This very remarkable insect is also in Mr. MacLeay's collec- 

 tion, and is marked " East Coast, N. Holland." I have never 

 seen it in any other collection. The sculpture of the elytra is 

 very different from any Garemmi hitherto noticed. 



15. — Carenum punctulatum. 

 Nigrum nitidum cyaneo-marginatum, elytris seriatim punctu- 

 latis puncto subapicali impressis, tibiis anticis extus 

 bidentatis. 

 Long. 81 lin., lat. 3 lin. 

 This insect scarcely differs from 0. marginatum, excepting in 

 the sculpture of the elytra, which in manjinatwn are indistinctly 

 striated, whereas in this species they are finely punctured in 

 rows. The fore tibia3 also have the two small tubercles more 

 distinct in this species. 



The specimen from which the foregoing description is taken 

 is in the cabinet of Mr. W. S. MacLeay, and is labelled " Byalla," 

 a place situated on a tributary of the Fish River, about twelve 

 miles north of Gunning. 



16. — Carenum variolosum. 

 Nigrum subnitidum, capite postico convexo, elytris dense foveo- 



latis foveis magnis rotundis, tibiis anticis tridentatis. 

 Long. 9 lin., lat. 3| lin. 

 This insect is labelled " Murrumbidgee" in Mr. MacLeay's cabi- 

 net, where it seems to be unique. It diifers from the C. localosnvi 

 of Newman in its head, which is large and drooping witli a broad 

 convex vertex ; it differs also in its thorax, by the deeply im- 

 pressed medial line which terminates near the anterior margin 

 in a wrinkled depression, which extends across from one anterior
