Cerylon distans, New Species 
(Fig. 29) 
The widely separated mesocoxal cavities will separate this species 
from all others in North America. In 'addition, the pronotum is 
much shorter and broader than in C. conditum , which also differs in 
having the clypeus notched in the male. The general form is similar 
to C. unicolor , in which the mesocoxae are more approximate, the 
size smaller, and the pronotal impressions shallower. 
Description. Length 2. 4-3.0 mm. Color dark reddish-brown to 
black; vestiture of very short, erect hairs, not visible under 50 X 
magnification. Antennae relatively short, about 0.6 X as long as 
pronotal width; segment 3 1.4 X as long as 4; club only slightly 
longer than wide. Clypeus slightly to moderately emarginate, but 
never notched. Pronotum about 0.87 X as long as wide, sides sub- 
parallel for basal three-fourths, converging apically to rounded angles; 
disc moderately convex at middle, steeply sloping anterolaterally, 
with 2 broad and moderately deep basal impressions ; punctation 
variable, coarser at base than apex, punctures near center about 
0.2 X as long as scutellar base and usually separated by less than a 
diameter; interstitial microsculpture very lightly impressed or absent, 
with scattered fine punctures. Scutellum transversely rugulose. 
Elytra about 1.6 X as long as wide and 2.35 X as long as pronotum, 
widest at middle; striae deeply impressed, their punctures elongate 
and subconfluent; intervals moderately convex, shiny, and finely 
punctate. Prosternal process slightly concave, about 1.8 X as wide 
as a coxal diameter. Mesosternal process 2 X as wide as a coxal 
diameter, truncate at apex. Metasternum 1.35 X as long as first 
visible abdominal sternite. Aedeagus (fig. 14) about 0.6 X as long 
as abdomen.
