126 PSYCHE [December 
scattered hairs, moderately stout and as long as the united lengths of the pedicel, 
ring-joints and the 3 proximal funicle joints or about half the length of the flagellum 
(including pedicel); scape as long as the funicel and twice the length of the club. 
Pedicel narrower, obconic, with a moderately long, tapering neck, distinctly twice 
longer than the proximal funicle joint, slightly longer than the united lengths of the 
two proximal funicle joints, and much longer than any of the following joints; ring- 
joints small, the first smaller than the second, about half its size, the second dis- 
tinctly three times smaller than the proximal funicle joint; funicle compact, the joints 
all wider than long and closely united, gradually widening distad and all about sub- 
equal, the funicle stout and nearly cylindrical; joints 1 and 2 of the funicle more 
nearly equal, longest, subquadrate; joint 3 slightly wider and shorter, joints 4, 5, 6 
nearly equal, widest and shortest, each about a fourth shorter and a third wider than 
joints 1 or 2 of the funicle; club compact, wider, conic-ovate, not quite half as long 
as the funicle, its basal joint somewhat longer and slightly wider than the distal 
funicle joint, the intermediate joint longer but narrowing distad, the apical joint 
conic, distinctly shorter. Pubescence of pedicel and ring-joints longer and some- 
what denser than that of the scape, but inconspicuous, that of the funicle and club 
similar, much denser, distinct and each joint has distinct longitudinal carinae, which 
appear in balsam-mounted specimens, high-power, as transverse rows of stout, flat- 
tened hairs attached caudad of the apical half of each respective joint and which may 
also give the appearance under high-power of whitened, longitudinal sulci. The 
pubescence of the flagellum is arranged in about two principal transverse rows, but 
not regularly so. Antennal bulbs separate for over their own widths. 
Left mandible 3-dentate, the inner (mesal) tooth broad, truncate, the inter- 
mediate tooth obtuse, conic, the outer (lateral) tooth acute, slightly the longest. Right 
mandible 4-dentate, the mesal tooth broadest, broadly rounded at apex, the two 
intermediate teeth subequal, short, small, curved, obtuse, the outer (lateral) tooth 
acute, longest. , 
(From 447 specimens, %-inch objective, 1-inch optic, Bausch and Lomb.) 
Male: Length, very variable; maximum, 2.0 mm.; minimum, 0.60 mm.; 
range, 1.4 mm.; average, 1.32 mm.; mode, 1.3 mm. Usually appearing a third 
smaller than the female. 
Aspect different, lighter in color, more brassy, metallic and green, the abdomen 
depressed, ovate to fusiform, usually concave dorsad, sometimes flat; rounded ven- 
trad, rarely convexed, shorter than the thorax; the vertex decidedly brassy; legs and 
antennae honey-yellow, excepting the coxae; clypeus less longitudinally rugulose, 
glabrous at the extreme apical meson, wider than long; wings smaller, more densely
