Mastostetlins pidirollis, iiiihi. 



Subelongatus, postice vix atteimatus, depressuy, pallide fulvus, 

 antennis capitis et thoracis maculis, scutello pleuris pedibusque 

 nigris, femoribus anticis quatuor subtus, posticisque fere totis, 

 fulvis ; elytris flavis, fascia basali ad margineni abbreviate, 

 altera prope medium iutegra, lineil pone medium, apiceipie nigris. 

 Long. 5 1 lin. 



Hab. Columbia. 



Head irregularly Ijut not very closely punctured, the extreme 

 vertex, a frontal vitta, the inner orbits of the eyes, a spot at 

 the base of each antenna, a transverse stripe across the clypeus, 

 together with the base of the labrum, black ; apices of jaws 

 nigro-piceous, antenna? (with the exception of the extreme base 

 of the first joint) entirely black. Thorax rather more than 

 twice as broad as long at the base ; basal margin sinuate on 

 either side ; apical border transversely truncate ; sides straight, 

 quickly converging from base to apex, anterior and posterior angles 

 distinctly produced, acute ; upper surface finely and irregularly 

 but not closely punctured, on each side, near the liinder angle, is 

 a large shallow fovea, just in front of this, • near the outer 

 margin, are several irregular faintly impressed excavations ; a 

 transverse spot on the centre of the disk, its anterior margin 

 deeply emarginate, together with an irregular longitudinal patch 

 on either side near the lateral border, black ; this patch is con- 

 nected at its upper extremity by a shorter one with the lateral 

 margin of the thorax, which is itself broadly edged, more 

 especially on its under surface, with black. 8cutellum broader 

 than long, trigonate, its surface distinctly punctured. Elytra 

 broader than the thorax, scarcely narrowed towards their apex, 

 surface depressed, rather closely punctured, pale flavous, a basal 

 fascia which is gradually dilated from the suture to the outer 

 margin, and extends across the humeral callus but is abruptly 

 arrested on the outer side of the latter, black, a common trans- 

 verse band which extends directly across the middle of the disk, 

 together with the apical sixth of the elytra also black ; between 

 the medial fascia and the apical patch, the s^iture and outer 

 margin are both narrowly edged Avith black.
