val punctured, discal lines abbreviated before the middle. 
Abdomen impunctate, convex. Legs dark red. 
@ antenne with the third joint not dilated, longer than the 
second, tenth obconical, usually not enlarged, the clypeus con- 
tinuous with the declivity of the front. 
Habitat. Georgia. 
This is the representative of another series of species, 
having the occipital foveze pubescent, the tenth joint not com- 
pressed, large, without a basal fovea. To this group belong 
B. nigricans, B. triangulifer, B. denticornis and B. cepha- 
lotes. 
B. CEPHALOTES, Casey. Piceous-blacks legs and antenne 
red; pubescence long, surface polished. Length, 2 mm. 
Plte X.; Fig.o0. Plate XII., Fig. 132: 
Head quadrangular, with the corners rounded, somewhat 
wider than long, occiput convex, sometimes bearing in the 
middle a very faint, short, carina; the eyes are small, promi- 
nent, tempora arcuate; the occipital foveze are pubescent, the 
connecting groove circumambient in the 4, obsolete in front in 
the 2, space between them polished, smooth, with a faint cen- 
tral impression, the separated margin broad, coarsely and 
sparsely punctured in front, where, in the male, it overhangs 
the clypeus; in the middle it is declivous and finely notched, 
the declivous part with a central emargination; the triangular 
lobes thus formed are setiferous, and separated from the clyp- 
eus by a deep interantennal excavation; from the bottom of 
the emargination emerges a serrate (quadridentate) plate; 
the clypeus bears in the middle an ovoid tubercle, provided at 
the apex, just beneath the tooth plate, with two divergent tufts 
of hair; the lateral margin of the clypeus is angulated and 
reflexed; the labrum is broadly emarginate. Antenne stout, 
the basal joint strong, longer than wide, convex below, 
slightly transversely concave above; second oblong, smaller; 
third to eighth still smaller, globular, ninth transverse. Tenth 
very large, truncate in the ¢, subglobular; the last, at least as 
wide as the tenth, ovoid, acuminate; in the @ the tenth joint
