34. Xenocerus buruanus sji. nov. 



S S . Similar iu structure to A', semiluctuosus, but not sexually dichromatic. 

 Thorax somewhat narrower than in semilurtuosiis, with three thin straight white 

 lines. Elytra black, marked with white : a short basal line uj)on suture: a second 

 at shoulder, sometimes connected with the tirst at basal margin; a tliird line 

 below shoulder and a fourth in stripe 4, often absent; behind middle of elytra there 

 is a transverse band stopping at the ninth interstice, almost straight behin<l in S, 

 somewhat suiuate at stri])e 3 in ? , convex in front, often ('.'//"') triangularly dilated 

 npon suture, but dilatation always short, nev(>r reaching scutelhir stripe. Scntelluin 

 white. Pygidium with a white line laterally, which is often reduced to a small dot. 

 Under surface white, but white hairs less dense in middle. Legs with sparse white 

 pubescence; femora more or less obviously rnfous.

In the jjattern of the elytra baruaimx comes nearest to lateralis, but the latter 

 belongs to a different section of the genus, having in the S the third joint of the 

 antennae very short and the fifth fringed, and in the ? the antennae of more than 

 half the length of tlie bndv.
