A species of shorter wider form than any of its immediate 
allies known to me; it is notable also for the great width of the 
excavation on either side the base of the prothorax and repre- 
senting the longitudinal sulcus, which however is not strictly 
speaking longitudinal being a trifle wider than long.

A. picturata, sp. nov. Mas.  Breviter ovalis; sat nitida; 
rufescens, supra dilutior, capite prothorace elytrisque con- 
cinne fusco- vel piceo-notatis, antennis ultra medium infus- 
catis; capite confertim subtilissime ruguloso, inter oculos 
transversim vix sulcato, macula* elongata fusca ornato ; 
antennis fere ut A. collaris sed articulo 1° magis elongato, 
2° minus brevi; prothorace utrinque macula magna fusca 
discoidali ornato, quam longiori fere triplo latiori, antice 
leviter angustato, confertim subtilius subrugulose punctulato, 
transversim et utrinque longitudinaliter sulcato, sulcis 
longitudinalibus normalibus, lateribus minus _ arcuatis, 
eequaliter preeter solitum late marginato, angulis anticis late 
subtruncatis ; elytris maculis nonnullis piceis bene deter- 
minatis (sc. macula basali litteram C simulanti et macula 
post mediana transversa contorta) et maculis fuscis com- 
munibus nonnullis in sutura dispositis ornatis, fere ut 
A. collaris sculpturatis sed puncturis seriatis magis crebris 
interstitiis magis crebre magis distincte punctulatis. Long.,

. Readily recognisable by the sharply defined markings of its 
upper surface and the prothoracic lateral margins distinctly wider 
than is usual in the genus, and of even width throughout their 
length.
