thus forming transverse bands.

Middle and Western States. The lateral margin of the thorax diverges into two as 
usual, but the upper one of these is accompanied by a fine approximate raised line from 
the middle to the anterior angle: a slight vestige of a similar line very near the anterior 
angle is seen in A. s u bf as c i a t u s, but is entirely wanting in the next. 
A. z e m e s Gory, Mon. Bupr. 4, 234, tab. 39, f. 225, is perhaps a variety of this spe¬ 
cies, in which the basal and middle pubescent spots are wanting, but the head is men¬ 
tioned in the description as being not impressed. 
1G. A. interrupt us, nigro-ncneus, granulatus, capite postice leviter sulcato, tliorace vage canaliculato, lati¬ 
tudine baud breviore, lateribus impressis rectis, angulis posticis longe carinatis, elytris costa discoidali postice ob- 
soleta, fovea basali, lineola ante medium maculaque postiea subsuturali pubescentibus, altera externa ad medium 
saepe deficiente, apice serratis rotundatis. Long. -24—32. 
Southern and Western States. Sufficiently distinct from the preceding by the simple 
superior thoracic margin: the pubescent line of the elytra extends from the basal fifth to 
the middle; sometimes it is by abrasion divided into two spots: a little behind its termi¬ 
nation there is a small external pubescent spot, to be seen in well preserved specimens. 
The sides beneath are pubescent. 
A. obsoleto-guttatus Gory, Mon. Bupr. 4, 25G, tab. 43, f. 249, is perhaps this 
species, but the description is somewhat indefinite, and the figure gives but little assist¬ 
ance in determining it. 
17. A. su b c i n c tu s, obscure seneus, capite sulcato, tliorace rugose punctato canaliculato, lateribus subito 
depressis, angulis posticis acutis planis, basi depresso, elytris fortiter granulatis, impressis, spatiis pubescentibus va- 
riegatis, sutura elevata. Long. -12—15.

New York; rare. Resembles at first sight A. su bf asc i a t us, but is at once dis¬ 
tinguished by the sulcate head, and flat thoracic angles.

18. A. latcbrus, obscure cyaneus vel nigro-viridis,granulatus, capite postice modice sulcato, tliorace canali¬ 
culato, antice postieeque impresso, lateribus profunde impresso maculaque parva albo-pubesccnte ornato, angulis 
posticis subcarinatis; abdominis lateribus pleurisque inaculis albo-pubcsccntibus signatis. Long. - 31—’44.
