Croion yellowish, with eight black spots, placed six on the anterior margin, the largest 

 next the eyes and somewhat square, the smallest somewhat rounded next the 

 centre ; at the base a brownish spot, enclosed by a narrow black border. Face 

 yellowish, with about eight transverse black streaks on each side, and a pale 

 brownish curved one on the upper margin. Clypeus : next the apex with a 

 black spot : lorce margined with black. In many examples the whole of the 

 characters on the head are almost obsolete. Elytra longer than the abdomen, 

 very pale testaceous ; nerves on both sides and some of the areas more or less 

 thickly, finely and irregularly powdered with piceous ; on the disc five pale 

 milky-white spots placed one in a line with the apex of the scutellum between 

 the claval suture and central nerve, another at the apex of that nerve, and one 

 at the base and apex of the ante-apical area immediately below the basal area. 

 Jrj?!^s entirely pale. Length, If lines 8. plebbius, Fall. 



This species may easily be separated from A. ohscurellus, to wtich 

 it is allied, by the milk-white spots on the elytra (most visible when 

 the insect is in repose), the difference in the characters on the head, 

 and the pale wings. 



Crown black, with a yellow T-shaped character in front, in the upper part of which and 

 just before the anterior margin are four black spots, frequently united ; on each 

 side at the base a narrow, semi-oval, narrow streak extending between the central 

 line and the inner margin of the eye. Face black, with from six to eight fine 

 yellow transverse lines on each side. Clypeus black, very narrowly margined 

 with yellow : lorm black, with a more or less large yellow spot in the middle. 

 Elytra longer than the abdomen, yellowish or yellowish-testaceous, tliiekly and 

 very finely spotted with dark fuscous or black, somewhat disposed in longitudinal 

 rows ; sometimes the spots ai'C united at irregular intervals, varying in different 

 individuals, and forming short lines, giving to the disc a somewhat reticulated 

 appearance. Wings dark fuscous at the base and apex. Thighs : 1st pair 

 black, base, a narrow ring before the apex, and the latter itself yellow.

In repose, this insect has always a dusky appearance, which varies 

 much in intensity. The absence of the milk-white spots ou the elytra 

 is sufficient to distinguish it from A. plebeius. 



This is the insect which has been doing duty in the collections of 

 this country under the name of Strong ylocephalus ag rest is, Eall. 



b. Anterior margin distinctly rounded ; angle somewhat acute. 



Crown yellowish-white, with a narrow, curved, black streak on each side of the centre 

 before the anterior margin ; across the middle a narrow, elongate, lozenge- 

 shaped, pale brown patch, its extremities joined to two short longitudinal lines, 

 •which reach the base and enclose between them two yellowish-white spots. Face 

 black, with about six short, slightly curved, transverse, yellow streaks on each 

 side, and a narrow yellow central line terminating in a spot of the same colour 

 at the apex. Clypeus black, with a yellow spot oia each side at the base ; some-
