654 COLEOPTERA 



The head is of moderate size, with two curved impressions between 

 the antennae, and a very indistinct transverse one in line with the back 

 part of the eyes ; just in front of this, and close to each of the latter, 

 there is an obvious puncture. The prothorax is broader than the head, 

 rather broader than long, gradually rounded to beyond the middle, and 

 from thence abruptly narrowed to the obtuse hind angles ; its widest part 

 is near the front ; it is but little convex, and slopes a little towards the 

 base ; the fine median furrow does not attain the apex, and before 

 reaching the base proceeds through a fovea-like expansion ; the posterior 

 depressions are situated close to the angles and are well defined ; the 

 oblique frontal impressions are faint ; the disc is almost smooth, but there 

 is a row of punctures, hispid as usual, in the marginal channel. The 

 elytra are rather broader than the thorax, elongate-oval, slightly convex, 

 and very perceptibly incurved or constricted just behind the shoulders, 

 exactly in line with the intermediate femora ; each has eight punctured 

 striae, the sutural least distinct ; between the eighth and the side there is 

 an abbreviated, smooth, raised space, and the side bears some large 

 shallow punctures which become rugose behind ; the interstices, except 

 those near the sides, are almost flat, but the sculpture becomes coarse 

 and confused posteriorly. 



Under-side reddish-black, impunctate. 



This species may be readily recognized by the incurvature behind 

 the humeral region (which is much more strongly pronounced than in 

 M. fulgida), red thighs, &c. 



Length, 9! lines ; breadth, 3. 



My unique example, a female, was discovered by J. D. Enys, Esq., 

 F.G.S., of Castle Hill Station, West Coast Road, Canterbury.

Nov. gen, 



Mentum broad, deeply emarginate, its wings incurved; the 

 median tooth stout, triangular, bi-setose at the base, nearly as long 

 as the wings. Ligula free and truncate at the extremity; paraglossae 

 narrow at apex, longer, soldered to the ligula for the greater part of its 

 length, the latter provided with two erect bristles. Palpi moderately 

 long, hairy, the terminal joint of the maxillary elongate, slightly oval, 

 truncate at apex. Mandibles robust, curved at apex, uni-dentate inwardly. 

 Eyes slightly prominent, finely facetted. Antenna filiform ; the first and 

 third articulations about equal, 2nd shorter; their pubescence begins with 

 the third joint. 



Head large, narrowed behind. Prothorax sub-quadrate, large. 

 Elytra sub-obovate, considerably and abruptly narrowed and sinuated 

 posteriorly. Legs of moderate length, comparatively slender ; femora 

 almost linear ; tibia straight, spinose at apex, the anterior notched, the 

 four posterior densely covered with slender spines ; tarsi rather slender, 

 densely hispid underneath, hairy above; basal joint elongate-oblong, 

 second elongate-triangular, third triangular, fourth cordate; claws 

 simple.
