Although this is by no means a rare insect, it appears to have 
escaped description hitherto. It is of somewhat broader and 
more robust form than B. signiferum, Newm. In the male the 
prothorax is by measurement just barely longer than wide, the 
length and breadth being equal in the female. The dark portions 
of the elytra are so ordered that the ferruginous part is simply a 
common patch on the anterior half of the suture occupying the 
whole base, contracting hindward and then expanding again.

B. mundum, sp. nov. Setis erectis sparsim vestitum; rufum, 
prothorace antice posticeque paullo infuscato, elytris piceis 
circa scutellum vix rufescentibus fasciis binis angustis 
subeburneis tortis albidis ornatis, femoribus (basi excepta) 
abdomineque piceis; cetera fere ut B. tricoloris sed prothorace 
paullo minus fortiter sculpturato. Long., 3 1.; lat., 4 1 
I can hardly specify any difference between this and the pre- 
ceding species except in the diminutive size of this, and the very 
different markings of its elytra, which consist of two slightly- 
raised transverse zigzag lines, one a little in front of the middle, 
almost hair-like in its narrowness, and scarcely reaching the 
suture ; the other a little behind the middle, somewhat wider, 
less zigzag, and distinctly reaching the suture. This insect must 
be very like Ectosticta eburatum, Pasc., but its coarsely-granulated 
eyes place it far from JZctosticta, and moreover its prothorax 
could not possibly be described as having “coarse crowded 
punctures,” the sculpture of its prothorax presenting the 
appearance rather of small almost-effaced granules.
