34 COLEOPTERA 



is well limited by a considerable basal depression, which, however, is 

 divided into two by the prolongation of the central ridge ; it is finely 

 margined, moderately closely punctured, and clothed with yellowish 

 hairs. Elytra elongate, transversely convex, parallel, wider than thorax, 

 with the upper part near the apex obliquely compressed, so that the 

 apical margin seems explanated ; the disc is rather flat, there is a 

 scutellar depression, and each bears a scutellar and ten punctured striae, 

 the second to the sixth are abbreviated or insulated by the junction of 

 the first and seventh at the apex, the interstices are but little elevated, 

 and their whole surface is covered with short yellowish hairs. 



Length, nearly 2 lines. 



I found one specimen only at Tairua ; its description will aid in the 

 identification of the other New Zealand species. 



619. A. ruficorne, n.s. This species is very similar to A. ampli- 

 colle, being of nearly the same size and colour, but the prothorax is 

 smaller, more rounded behind, and, though depressed at the base, the 

 depression is less obvious, and the antenna differ from those of that 

 species ; these are nearly twice the length of the thorax, dark red in 

 colour ; their tenth joint is a little smaller than the ninth, and the 

 eleventh is of nearly equal thickness throughout, so that it is not of the 

 acuminate elongate-oval form of the typical species, it is longer than the 

 ninth, and of the same length as the slender stalk (joints three to six). 



Length, if line. 



Three mutilated examples found near Whangarei. 



620. A. IlOtata, n.s. Sub-cylindrical, transversely convex ; pitchy- 

 brown, with a large humeral and sub-apical spot on each elytron testace- 

 ous ; legs red, tarsi yellowish, antennae infuscate red. 



Antenna scarcely so long as the elytra, eleven-jointed ; basal joint 

 stout, a little longer than second to fourth taken together ; second small, 

 yet obviously larger than the third ; third and fourth very small ; fifth 

 rather large, dilated inwardly so as to be triangular ; sixth small and 

 slender, nearly as long as the third and fourth ; seventh large, longer 

 than fifth, elongate-triangular ; eighth small, similar to sixth in size and 

 shape ; ninth slightly longer but narrower than seventh, less triangular 

 than it ; joints ten and eleven elongate, ea^i a little longer than the 

 ninth. 



Prothorax not much longer than broad,- -transversely convex, base 

 sub-truncate, apex but slightly projecting, its sides slightly but widely 

 incurved, so that the front and hind angles seem to be prominent ; it 

 has an indistinctly depressed dorsal line, is so sculptured as to appear 

 rugose, and, near the sides, its surface is clothed with yellow hairs. The 

 elytra are more than twice the length of the thorax, transversely convex, 

 almost parallel, and bear punctured striae; these, owing to the short 

 scutellar striae, are somewhat bent, and the interstices are so clothed 

 and sculptured that they appear to be a little rough. Legs moderately 

 long, the anterior tarsi shortest, with the basal joint rather elongate, 

 quite as long as the next two in the hind pair. Last joint of maxillary 

 palpi sub-securiform. Eyes moderate,
