246 REVISION OF THE BUPRESTID@® OF THE UNITED STATES. 
the thorax being rounded, but by having pubescent spots outside of the discoidal costa, 
thus forming transverse bands. 
15. A. fallax, obscure seneus, granulatus, capite tenuiter canaliculato virescente, thorace vage canaliculato, 
latitudine haud breviore, lateribus impressis vix rotundatis postice subsinuatis, margine superiore antice duplici, 
angulis posticis longe carinatis, elytris costa discoidali prope apicem obsoleta, fovea basali maculisque duabus sub- 
suturalibus pubescentibus, apice serrulatis rotundatis. Long. -28.

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.subfasciatus, but is entirely wanting in the next. 
A. zemes 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. 
16. A. interruptus, nigro-eneus, granulatus, capite postice leviter sulcato, thorace vage canaliculato, lati- 
tudine haud breviore, lateribus impressis rectis, angulis posticis longe carinatis, elytris costa discoidali postice ob- 
soleta, fovea basali, lineola ante medium maculaque postica subsuturali pubescentibus, altera externa ad medium 
seepe deficiente, apice serratis rotundatis. J.ong. 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, 256, 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. subcinctus, obscure xneus, capite sulcato, thorace 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.subfasciatus, but is at once dis- 
tinguished by the sulcate head, and flat thoracic angles. 
18. A. latebrus, obscure cyaneus vel nigro-viridis, granulatus, capite postice modice suleato, thorace canali- 
culato, antice posticeque impresso, lateribus profunde impresso maculaque parva albo-pubescente ornato, angulis 
posticis subcarinatis; abdominis lateribus pleurisque maculis albo-pubescentibus signatis. Long. -81—-44.
