punctuation of the thorax and elytra is considerably stronger than in A. scalaris. The 

 elytra have a narrow lateral yellow line extending to near the middle ; it has a small 

 notch just below the shoulder, and at its apex unites with a yellow spot which surrounds 

 a black spot on the margin. There is a small oblique spot at the base near the suture, 

 a smaller one just below this, then two spots which are sometimes united obliquely, 

 then one or two spots near the suture, then two on the margin, the next is at the 

 suture, and then there are two on the margin. The apical segment of the abdomen is 

 rather broadly truncate in the male.

This species somewhat resembles A.flavosticta in its general form and coloration. 

 The thorax is much more finely punctured on the disk, the lateral impression is distinct 

 and terminates in a round fovea at the base. The sides are much less rounded, and the 

 posterior angles fit close to the elytra. The elytra have numerous small yellow spots, 

 which seldom extend beyond one interstice, except several which unite and form a 

 larger spot about the middle near the side ; there is a single spot behind the humeral 

 callus, another a little behind it on the margin ; two about the middle of the margin 

 (on the ninth and tenth interstices) close to the larger spot above mentioned ; behind 

 these are two others, placed similarly ; then there is the first red spot, a little removed 

 from the margin ; then the second red spot, nearer the margin, and with a yellow spot 

 outside it ; and close to the apex is the third red spot. The apical segment of the 

 abdomen is arcuately acuminate.

Elongata, sat angusta, nigro-senea, nigro-pilosa, subtus senea, griseo-pilosa ; thorace bene transverso, antice 

 et postice parum angustato, lateribus medio parum angulatis; elytris elongatis, flavo maculatis, supra 

 depressis, punctato-striatis, striis juxta suturam vix impressis subtiliter punctulatis, reliquis fortiter 

 punctatis, interstitio quarto perparum elevato.

This species is allied to A.flavopicta, but has the elongate form of A. rubronotata, 

 with the elytra flattened on the back as in A. flavomarginata. The thorax is very 

 short ; at the base it is the same width as the base of the elytra, at the middle it is a 

 little broader and is slightly but distinctly angular. The disk is not very strongly and 

 not very thickly punctured, the basal impression is well marked, and the anterior 

 channel very distinct ; the sides are rugosely punctured, with the usual impression deep
