paler. Some specimens (teneral?) are yellowish to reddish-brown, 
nearly unicolorous, with elytral pustules only slightly paler. Very 
short setae (similar to that in fig. 28) sparsely distributed over body 
surface, legs more densely setose, especially tibiae and tarsi. Length: 
3.0 ± 0.2 mm (2. 6-3. 5); width: 1.3 ± 0.1 mm (1.1-1. 5) (N = 55). 
Head capsule as in figs. 6, 7, and 58, epistomal suture with median 
stem (not always visible on surface). Antennal length about 1.1 
times head width, first six antennal segments without dense pubes- 
cence, antennal club five-segmented, gradual (see fig. 54). Ocellar 
diameter about 0.095 times head width. Labrum shallowly emar- 
ginate anteriorly as in fig. 6. Maxillary palp with fourth segment 
about three times as long as third, the two approximately subequal 
in width, 
Pronotum as in fig. 1, with several small shallow paramedian and 
lateral depressions; lateral margins explanate. Prosternum deeply 
pitted and rugose, but lacking microsculpture, and without median 
longitudinal carina (see figs. 18-21). Mesosternum with dense 
irregular microsculpture, cavities for reception of procoxae about 
half the length of the mesosternum; mesosternal process fairly 
narrow, blunt, extending seven-tenths of the way between meso- 
coxae (see figs. 34, 36). Metasternum convex with faint median 
longitudinal depression, surface without microsculpture but with 
short setae in large punctures (see fig. 36), antecoxal sutures short, 
extending only three-tenths the width of the metasternum (fig. 60). 
Protibia setose, with several small spines on outer surface (fig. 23), 
meso- and metatibia with slightly more spines. Hind tarsus six- 
tenths as long as hind tibia, fifth segment of hind tarsus two-thirds 
as long as first four together. Empodial setae subequal in length to 
tarsal claws. 
Elytral striae impressed between punctures, intervals punctate 
and with short fine setae (in addition to macrosetae on alternate 
intervals; see figs. 26, 27). Pale pustules located anterior and 
adjacent to macrosetae. Angle formed by elytral apices at suture 
about 180°. Wings fully developed, with anal flap. 
Abdomen with tergites 4 to 8 well sclerotized, spiracles located in 
tergites of these segments; paratergites separated anteriorly but not 
posteriorly from sternites on segments 4, 5 and 6 (see fig. 47), 
apparently not separated from sternites on segments 3 and possibly 
7. Tergites 4 and 5 with paired patches of medially-directed
