NEW BRITISH SPECIES NOTICED IN 1859. 97 



subquadrate, posterior angles obtuse, elytra elongate- 

 ovate, delicately striate, interstices flat , with five im- 

 pressed jjoints, base of antennas and legs pitchy red. 

 Length A\ lines. 

 Antennas distinctly longer than the head and prothorax, 

 about half the length of the entire insect, pitchy, the basal 

 joint rusty red ; mandibles and palpi pitchy. Head narrow, 

 triangular, with the usual pair of punctures on the margin 

 of each eye, and two longitudinal shallow foveas in front, 

 between the antennae ; with these exceptions, smooth, brassy, 

 with a greenish tint anteriorly and a faint coppery hue pos- 

 teriorly. Prothorax subquadrate, its width slightly exceeding 

 its length, scarcely narrower behind than in front, its sides 

 slightly rounded, rather deeply emarginate in front, very 

 slightly so behind, posterior angles distinct but obtuse, lateral 

 margins reflexed, especially posteriorly, basal foveas broad, 

 deep and well defined, finely transversely rugose, with a few 

 indistinct punctures, dorsal channel distinct, disc with faint 

 transverse undulated strigas, brassy, with a faint coppery 

 hue, the sides with a brassy tint. Elytra elongate-ovate, 

 thrice as long as the prothorax, rather depressed, very de- 

 licately but distinctly striate, interstices flat, the third with 

 five punctures, of which the three anterior are contiguous to 

 the third stria, the two posterior to the second stria, brassy, 

 with a faint coppery tint. Thighs pitchy black, tibiae rufous, 

 tarsi pitchy red. 



At once distinguished from its nearest ally, A. parum- 

 punctatus (Icevis, Daws.), by its more slender form, its 

 longer depressed elytra, and the obtuse (not rounded) pos- 

 terior angles of its prothorax. 



I have drawn up the above description from a specimen 

 (?) taken by Mr. Brewer in the spring of this year, near 

 I860. h
