elytra with a large semitriangular patch at the base, and another 

 from the middle to nearly the apex, of a brownish purplish colour 

 Length 1\ lines. 



Vertex of head smooth, impunctate, limited in front by four 

 transversely placed deep punctures, and from the clypeus by several 

 deep indentations ; apex of jaws black ; antennae robust, all the 

 joints, except the second, of equal length, slightly diminishing, how- 

 ever, towards the apex, of a uniformly fulvous* colour, and closely 

 pubescent. Thorax transversely subquadrate, the sides nearly pa- 

 rallel and narrowly thickened, but not depressed ; anterior angles 

 convex but not produced outwards ; surface impunctate, shining f 

 a very light testaceous colour ; scutellum fulvous ; elytra rather 

 convex, distinctly margined, very minutely punctate, of the same 

 colour as the thorax ; each elytron with a large patch at the base 

 rounded anteriorly, and not touching either the margin or the 

 suture and another one triangularly shaped, the point directed 

 towards the apex, of a reddish-brown colour, with a very distinct 

 purplish gloss. Taking these patches as the ground-colour, they 

 would be limited by the suture (widened anteriorly), a narrow band 

 across the middle, and by the lateral margins of a light flavous 

 colour. Underside testaceous, legs flavous, claw-joint not swollen 

 Metatarsus as long as the two following joints united.

This species is closely allied to A. nobilitata, Fabr. ; but the want 

 of the transverse band on the thorax, together with the different 

 shape of the latter, as well as the shape of the patches on the elytra 

 will distinguish it from that species. ' 



10. AsPILERA PALLIDA, Sp. 110V. 



Broadly ovate, black ; apex of abdomen and the thorax more or 

 less fulvous ; elytra pale testaceous, shining, impunctate. 



Length 4| lines. 



Head shining black, impunctate, with the usual transverse depres- 

 sion ; antennas of half the length of the body, uniformly black, 

 covered thickly with whitish hairs. Thorax comparatively wide 

 about twice as broad as long, its sides evenly rounded, narrowly 

 margined but each side rather indistinctly limited by the more 

 convex disk, the anterior angles very acute and distinctly produced 

 inform of a short tooth, basal margin very slightly sinuate at each 

 side, almost straight. Surface scarcely visibly punctate, of a lighter 

 or darker flavous colour ; scutellum shining black ; elytra slightly 

 wider at the base than the thorax, widened till behind the middle 

 from there rounded to the apex, distinctly margined, smooth and 

 shining, of a light testaceous colour, more or less stained obsoletely 

 with fuscous in some specimens. Underside and legs shining black 

 the latter closely pubescent ; apex of abdomen fulvous. Posterior 

 thighs very moderately thickened ; metatarsus longer than the fol- 

 lowing joints, the claw simple, not thickened.
