another about a third of the length of the elytra from the apex, 

 and another on the third stria, about the same distance from 

 the base; the exterior interstice with a series of round flat- 

 bottomed fovese ; margin inflexed, both the inflexed portion and 

 the raised edge of the margin testaceous ; an oblique irregular 

 testaceous patch near the base of each elytron, on the fifth, 

 fourth, third, second, and part of the first interstices, parallel to 

 the side of the scutellum, though at some distance from it ; the 

 mark on the third interstice reaches farthest back, that on the 

 fourth farthest forward ; an irregular, jagged, testaceous band 

 near the apex also runs across the whole elytra, but indistinct at 

 the suture and on the exterior interstice ; the space on the first 

 two interstices reaching nearest to the apex, the two next farthest 

 from it, and the three last again approaching it. The apex is 

 obliquely truncate and excised, the exterior angle sharp, the 

 sutural angle prominent, but scarcely toothed ; the last segment 

 of the abdomen punctate on the upper surface; under side of 

 body smooth, shining, impunctate. Legs slender ; tarsi simple ; 

 claws pectinate. 



I have named this species in memory of my lamented friend 

 Lieut. -Colonel Champion, who fell at Inkermann, a naturalist 

 whose loss will be long felt. 



2. N. intermedia, mihi. 



Valde affinis N. Championi, sed parum minor, labro magis elou- 

 gato et ad apicem canaliculato ; mandibulis acutioribus ; tho- 

 race minus transverso et postice angustiore ; elytris apice emar- 

 ginatis sed non dentatis, angulis posterioribus rotundatis, cum 

 maculis anticis grandioribus et maculis posticis minus continuis.

Has very much the appearance of N. Championi, but, on com- 

 parison, is readily distinguished by the characters mentioned 

 in the above diagnosis. The insect is smaller, and the colora- 

 tion a little darker. The labrum is longer, and narrowed to- 

 wards the point, where it is canaliculated. The mandibles are 

 more slender, more acute, less rounded on the exterior, and 

 narrower at the base. The head is narrower, and is marked by 

 a number of minute longitudinal wrinkles. The thorax is not 

 so transverse and is narrower behind, and the reflexed margin 

 is not quite so broad. The elytra are rounded at the posterior 

 angles instead of being toothed, and the testaceous markings on 

 them are slightly different ; the anterior marking is confined to 

 the same striae, but is comparatively rather larger from the colour 

 running further on some of them ; it runs up on the second and
