1 40 COLEOPTERA 



deeply impressed between the frontal tubercles ; from each side of the 

 impression proceeds backwards a deep furrow, which terminates between 

 the eyes as a fovea-like expansion. 



Thorax much narrower than the elytra, about as long as broad, 

 much narrowed behind, with a very large impression behind the middle, 

 which is connected on each side with a deep large fovea near the hind 

 angles. Elytra distinctly longer than the thorax, with the sutural stria 

 deeply impressed at the base, and with a rather large intra-humeral 

 impression. 



Auckland. The male sent by Mr. Edwards, the female by Mr. 

 Lawson. 



Note. — I found a specimen at Tairua. 



255. E. trisulcicollis, n.s. Allied to E. convexiis. Anteiince. 

 with the exposed portion of the basal joint very little longer than the 

 second, which is not quite so stout as the first and quite globular; joints 

 three to eight about equal ; ninth a little larger than eighth ; the tenth 

 not much larger than the ninth ; eleventh large, oval ; they are as long 

 as the head and thorax, finely pubescent, and of a clear red colour. 



Head large, nearly as large as the prothorax, the greater portion from 

 the antennal channel to a line behind the eyes, rather deeply concave, 

 the hind portion, therefore, is seemingly much elevated, with its middle 

 part projecting into the frontal cavity. 



Thorax cordiform, about as long as it is broad, a good deal nar- 

 rower than the elytra, considerably and rather abruptly rounded in 

 front, and more gradually contracted posteriorly ; there is a deep 

 rounded fovea in the middle near the base, a curved depression pro- 

 ceeding from it towards each side, and a straight dorsal groove extend- 

 ing to the apex ; besides these impressions, there is a broad groove 

 from each hind angle extending along the side, and nearly attaining the 

 front angle, so that the sides seem to be explanated. 



Elytra not much longer than thorax, narrowed towards the shoulders; 

 each with a broad sutural groove, and a still wider depression between it 

 and the shoulder, so that the intervals, as well as the humeral region, seem 

 somewhat elevated ; they are clothed, like the head and thorax, with 

 short yellowish hairs. Hind-hody smaller than elytra, gradually deflexed, 

 and densely clothed. 



The head and thorax are dark shining red, elytra a little paler, and 

 the legs are of the same colour as the antennae. 



liCngth, nearly i line. 



I found several specimens at Tairua. 



256. E. asper, n.s. Body red, rather dull, the antennpe and legs 

 yellowish. Head with the frontal tubercles small and smooth, and two 

 rounded foveit^ on the vertex, the surface dull and rough, owing to its 

 punctation. Prothorax cordate, larger than head, considerably 

 rounded laterally ; wuth an impression behind the middle, and a fovea 

 at each side, all three as near to the middle as to the base, a smooth 

 impression proceeds from the central fovea towards the apex, the rest of
