1356 COLEOPTEBA 



not raised margins ; posterior angles rectangular, the anterior 

 moderately prominent; the apex with a slight median and large 

 postocular sinuosities, the base widely Insinuate ; the middle of the 

 disc is raised, smooth before and behind, but, at each side of this 

 central portion, with dense sculpture, which may also be seen on 

 other spots : there are numerous punctures and minute tubercles or 

 granules on the surface. Elytra with somewhat similar sculpture 

 arranged in lines, and with minute asperities on the interstices ; on 

 the top of the hind declivity . there are two nodules on each elytron, 

 the external the larger, and near the suture, in line with the others, 

 there are two smaller indistinct ones ; there is a sort of duplicate or 

 furcate plica behind each shoulder, and some irregular elevations 

 behind near each side. The antennal orbits are more elevated than 

 in Periatrum. The first antennal joint is but little exposed. 



Length, 3 ; breadth, 1-j- lines. 



Eiccarton, near Christchurch. Mr. H. Suter has been kind 

 enough to send me the only specimen he could find. In its natural 

 condition it may, at first sight, seem like an Enarsus. 



Group-MELANDRYID^E.

2377. A. CStvelli, n.s. Elongate, more narrowed behind than in 

 front, subopaque, pubescence fine and rather pallid ; 'the body dark- 

 fuscous ; on each elytron there is a large pale mark which, at the 

 base, does not reach the side or the sutural stria ; in line with the 

 hind thigh there is a small spot which, at the side, is longitudinal, 

 but forms an indistinct transverse fascia behind ; there is also an 

 obscure spot near the apex. The palpi are yellowish, their terminal 

 joints are narrow but nearly cultriform. Antenna elongate, filiform, 

 inserted in small cavities just in front of the middle of the eyes ; 

 their basal joint is slightly curved, the second is hardly more than 

 half the length of the third. The eyes extend from the upper to the 

 lower surface, and are scarcely at all emarginate in front. Thorax 

 rather longer than broad, narrowed towards the front, with an 

 oblique depression near each side, and a narrow one at the middle, 

 all at the base, which is closely applied to the elytra ; its surface 

 finely and closely sculptured. Elytra with the suture simple, a 

 sutural stria, and an elongate impression inside the shoulder ; they 

 are sculptured like the thorax. 



Anterior coxa contiguous. Tarsi filiform, their fourth joint 

 hollowed out above and almost bilobed ; claws appendiculate at the 

 base. Spurs of the tibiae distinctly pectinate. 



This species, I think, represents a distinct genus, but I refer it to 

 Allopterus until more specimens of this group can be procured, so 

 that the generic characters may be more carefully studied.
