times the face is yellowish, with six or soren short slightly curved black strenks. 

 Elytra much longer than the abdomen, yellow. Clavtts with a narrow brown 

 line down the inner margin of the dorsal nerve, interrupted by the white apices, 

 of the nerves. Corium : anterior marginal nerve somewhat brownish-yellow ; 

 apices of the ante-apical areas frequently brown ; nerves slightly paler than the 

 disc. Thighs : 1st pair yellow, more or less black at the base, and with a narrow 

 black ring before the apex, sometimes only represented by a spot on the inside.

In general appearance, tins insect bears a strong resemblance to 

 tlu' following one, from which it may at once be distinguished by the 

 absence of the black spots in the clavus and corium. 



On the continent, two other species belonging to this group occur, 

 viz., A. eryth'ostictus, Fieb., and A. simplex, H.-Sch., and I think it 

 very probable that they may be met with in this country. Both have 

 pale heads as in A. dilutior, and, when in repose, they much resemble 

 the ? of A. suhfusculus in the elytra. 



Crown yellowish-white, with a somewhat triangular pale brownish spot in the middle 

 on each side of the centre. Face testaceous-yellow, with about seven short, 

 curved, transverse pale brown lines on each side, slightly broader than the pale 

 spaces : lorm at the base with a short narrow brown margin. Elytra much 

 longer than the abdomen, yellowish-testaceous. Clavus with two short longitu- 

 dinal black streaks, one adjoining the claval suture and about in a line with the 

 apex of the scutellum, the other situated a little higher up ; apices of the nerves 

 white ; apex narrowly piceous. Corium with two short longitudinal black 

 streaks, placed one near the apex of the basal area, and the other near the base 

 of the ante-apical area immediately below it. Thighs : 1st pair with a narrow 

 black streak down the inside, in some cases obsolete. Length, 2^ lines. 



11. DILUTIOE, Kirschb. Qlebilis, Fiob.). 



The pale head and black streaks on the elytra of this species will 

 at once serve to separate it from tlie foregoing. 



Crown pale testaceous, without markings. Face pale testaceous, the upper portion 

 with sometimes tliree or four short transverse brownish streaks. Elytra much 

 longer than the abdomen, pale yellowish-green ; apex slightly brownish ; nerves 

 paler than the disc. Thighs: Ist pair yellow. Length, 2i — 3 lines. 



12. PKASiNUS, Fall. 



According to Ficber, this is A. Zelleri, Kirschb., and A. 2>')'asinus, 

 Kirschb., is A. simplex, ll.-Schf. 



Crown black, with a yellow anchoriform cliaractor in fi'ont, and two short transverse 

 yellow streaks in a line with the anterior margin of the eyes, and two others 

 near the base ; basal margin narrowly, inner margin of the eyes and a spot near 

 the latter, yellow. Face black, with seven or eight short, slightly curved, trans- 

 verse yellow lines ; down the centre a fine yellow line, terminating at the apex
