correspondents. 
It varies, very much like Sten. fulvitarsis, in size, some male speci¬ 
mens not being more than half the ordinary size. 
Stenocerus tessellatus, Jekel. 
Chains, supra lateribusque parum deplanato-impressus, piceus , fundo 
obscure brunneo-tomentosus ; margine interiori oculorum lineolaque 
basi verticis, thoracis disco irregulariter plagiatim maculisque quatuor 
transversaliter positis ante medium, scutello, elytrorum sutura inter- 
stitiisque alternis irregulariter basi utrinque subplagiatim posticeque 
subfasciatim, tibiarum annulo ante-medio articuloque basali tarsorum 
Jlavo-fulvescente tomentosis ; thorace lateribus mediocriter bisinuato , 
maculis duabus apicalibus tribusque dorsalibus ante medium obsoletis 
duabusque connexis ante medium basis, etiam nebula laterali fuscis 
ornato; interstitiis alternis elytrorum fusco tessellatis. 
Patria : Carthagena, Columbise, Dom. Dupont (Lebas). 
This species also resembles Sten. migratorius and Sten. Amazonce ; in 
its proportions and size it is more allied to the former, but is generally 
smaller. The thorax is nearly as conic, its second (anterior) lateral lobe 
is as oblique as in Sten. migratorius , but it is more convex, though less so 
than in Sten. Amazonce; its posterior depression is smaller, shallower than 
in both, and the anterior median elevation is nearly obsolete, or, rather, 
each side of this longitudinal impression is so obsolete that the anterior 
convexity is scarcely divided into three longitudinal elevations, as in those 
species ; the fuscous spots are placed in the same manner, but inde¬ 
pendently of the two lateral punctiform spots (one on each side above the 
middle) there are two others on the disc, altogether forming a transverse 
row of four spots; there are also two others on each side of the disc above 
the base, and a duplicate fuscous one between these: the elytra are less 
shortened, widened and convex than in Sten. Amazonce, nearly as narrow 
posteriorly, but more so than in Sten. migratorius and Sten. mexicanus : 
above all, they are, with those of Sten. brunnescens, less depressed along 
the suture and at the sides, and consequently the most apparently and most
