Ischyropalpus decoratus, new species 
This species, known only from the female holotype, is the only one 
in the group with a marked color pattern on the elytra. These are dull 
luteous with the basal area and a crescentric marking behind the middle 
on each elytron brown, the two connected by a narrow strip that 
parallels the suture. The suture is pale in a strip 0.17 mm wide, be- 
coming darker at the base but feebly indicated even there. The prono- 
tal punctures are more or less confluent longitudinally and the elytral 
pubescence is moderately dense, fine and appressed. 
Holotype Length 2.88 mm. Brown, the head slighty darker, the 
elytra as described above, the antennae, palpi and legs dull luteous also. 
Head subquadrate, with distinct but short tempora, the base gently 
curved between the distinct temporal angles. Length 0.49 mm, width 
across eyes 0.59, behind 0.49. Eyes large, moderately prominent, 0.28 
X 0.20 mm, separated by 0.40 on front, extending far down on sides 
of head. A line connecting their hind margins is 0.15 mm from middle 
of base. Facets moderately coarse, with curved setae at their intervals 
ca. 0.02 mm long. Surface of head densely covered with sharply de- 
fined flat-bottomed punctures ca. 0.03 mm from center to center, 
separated by less than half their diameters, slightly sparser on anterior 
part of frons; intervals smooth and shiny. Setae appressed, fine, ca. 
0.03 mm long, tactile setae straight, erect, ca 0.01 mm. Frontoclypeal 
suture feeble, the clypeus on same curve as front. Last segment of 
maxillary palpi narrowly securiform, 0.14 X 0.08 mm. Antennae 
moderately stout, with segments 2-10 thickest near apex, becoming 
subtrianguler. Measurements in 0.0 1 mm: 15/6, 8/6, 8/5, 8/6, 8/6, 
8/7, 8/8, 8/8, 8/8, 8/8, 13/8. Segment 1 subparallel, feebly pedun- 
culate, 2-3 thickest near apex, 4-10 subtriangular, becoming heavier, 
9-10 subtruncate at base, 11 truncate at base, the sides gently curved 
to the blunt apex from near base. Setae and tactile setae rather shaggy. 
Pronotum 0.67 mm long, 0.38 wide at base, 0.56 maximum and 
0.26 at the short but well-defined collar. Sides widest at apical 2/5, 
almost evenly curved to collar and almost straight back to the level 
of the distinct basal impressed line. Disc almost evenly convex, slight- 
ly concave behind middle. Punctures denser and smaller than on head,
