PITYOPHTHORUS SAMBUCI, new species 
PLATE 23, FIGURE 38 
Reddish brown to piceous-brown, brightly shining: 1.43-1.65 mm. 
long, holotype 1.6 mm. long, 2.7 times as long as wide; allied to 
Pityophthorus rhois Swaine of Group I. 
Frons broadly, transversely impressed below in both sexes, shining, 
deeply, somewhat roughly, moderately finely and closely punctured 
below, more sparsely and roughly so above; median carina indicated 
by a small tubercle on epistoma; hairs short, fine, inconspicuous. Eye 
with moderate facets, about one-third divided by a rather wide emar- 
gination. Antenna (fig. 38) with club about 1.83 times as long as 
wide, widest through second segment, first two sutures partly septate, 
transverse. 
Pronotum about 1.09 times as long as wide; posterior angles rounded, 
sides weakly arcuate on posterior two-thirds, definitely constricted 
just behind broadly rounded, serrate front margin; anterior area with 
asperities fused at bases to form 4 (including front margin) contin- 
uous, concentric ridges; summit slightly anterior to middle, distinctly 
impressed behind it; posterior area with deep, moderately large, rather 
sparse punctures (coarser and sparser than in rhozs), smaller on sides, 
with a nearly impunctate area; median line rather wide, impunctate, 
very feebly elevated. 
Elytra very slightly wider than pronotum and 1.56 times as long. 
widest slightly before middle, about 1.64 times as long as wide, sides 
nearly straight (very feebly arcuate) and subparallel on anterior 
three-fourths, very broadly rounded behind; surface piceous-brown, 
brightly shining; punctures deep, moderately large and close, in defi- 
nite strial rows, only first striae impressed ; interspaces rugulose, often 
more strongly near base, impunctate on anterior two-thirds of disk. 
Declivity rather abrupt, suture wider and more elevated than on disk, 
more strongly near apex, without granules and nearly devoid of 
punctures and hairs; first and second striae with strong punctures; 
second interspace depressed, forming fundus of sulcus at each side, 
lateral convexity higher than suture, with numerous punctures, a few 
small, obsolescent granules and with rather long, erect hairs. 
There is little difference between the sexes of this species. Some 
specimens, supposedly females, are slightly larger and slenderer.
