lato ; elytris sat crebre punctatis, utrinque fascia arcuata ad basin, 
altera vix pone medium transversa, utrinque abbreviata, macula- 
que ante apicem subrotundata fulvis. 
Long. 3 lin. 
Hab. Guatemala. 
Head scarcely longer than broad; front impressed above 
the encarpte with a deep fovea; encarpae shining, thickened, 
subquadrate ; carina not defined ; antennae filiform, the second 
joint short, the third nearly one half longer than the second, 
the fourth more than equal in length to these two united. 
Thorax nearly a third broader than long ; sides parallel, 
sinuate behind the middle, the anterior angles thickened, ob¬ 
tuse; disk subremotely punctured, impressed on either side 
just behind the middle with a round fovea; behind these, in 
front of the basal margin, is a third, smaller and less defined. 
Elytra distinctly punctured, slightly depressed on the inner 
disk, below the basilar space; each elytron with three large 
fulvous markings : the first, broad, commences immediately 
below the basal margin between the suture and the humeral 
callus, curves round the latter, and terminates some distance 
within the lateral margin; the second, placed scarcely below 
the middle, forms a transverse band, abbreviated on the 
suture and on the lateral border, its hinder margin sinuate ; the 
third, subrotundate, is placed near the apex. Lateral margin 
of abdominal segments narrowly edged with flavous.

Head broader than long, trigonate; front impressed above 
the encarpte ; the latter transverse, thickened, distinctly 
separated from the front, confluent with each other on 
the median line; carina raised, linear ; antennse filiform, the 
second joint short, the third twice its length, nearly three 
fourths the length of the fourth ; the four lower joints obscure 
fulvous, the three upper ones yellowish white, the extreme 
apex of the terminal one black. Thorax rather more than one 
fourth longer than broad; sides parallel and obsoletely sinuate 
from the base to beyond the middle, thence converging to the 
apex ; disk moderately convex, shining, impunctate. Elytra
