OF WASHINGTON. 171 
in the form of two rows of six or more punctures gradually increasing in 
size to apical constriction, in posterior half with large, irregularly placed, 
and confluent, foveate punctures. In the posterior third there is also 
on each side a rather large oval slightly depressed area, with contiguous 
shallow punctures considerably smaller than those in the interspaces 
and much larger than the punctures of the sides, which are fine but dis- 
tinct and sparse. Scutellum flat, shining, moderately declivous to base. 
Elytra one-fifth wider than thorax, somewhat strongly narrowed to 
apex, where the surface is a little uneven. Striae moderately fine and 
deep, finely and closely punctate (16-20 punctures on longest striae); 
punctures short, oval on disc, round and shallow at sides. Intervals 
nearly equal in width and convexity; i, 3, 5, and 9 partially biseriately 
and very finely punctulate, others uniseriately and scarcely less finely 
but less closely punctulate, 3 distinctly elevated in anterior half, 5 less 
distinctly; 8 and 9 considerably depressed and coated; humeral callosi- 
ties small but well defined, subapical ones subtubercular. Pygidium very 
strongly, coarsely and densely punctate. 
Lower surface strongly, coarsely, and moderately sparsely punctate, 
punctures not remarkably coarser on the sides. Legs a little less strongly 
punctate than middle of abdomen. Tibiae sinuate, and finely fimbriate 
on inner surface, subapical spurs minute. Anterior tibiae with inner 
spur acute and long, placed nearly at a right angle, outer angle slightly 
produced; middle tibiae a little rounded at apex, posterior tibiae obliquely 
truncate. Third joint tarsi : anterior one-fourth, middle one-fifth, posterior 
one-fifth + , wider than first joint. 
c?. Pygidium wider than long, broader and more broadly rounded at 
sides of apex, lateral tufts minute. Ventral surface much more uniformly 
punctate than in $ , first and second abdominal segments weakly concave, 
third and fourth distinctly but sparsely punctate, last segment densely 
punctate and without finely punctate basal area. 
$ . Pygidium a little longer than wide, moderately narrowed and 
rounded at apex, strongly divided by a median carina, each side of which 
there is a large deep fossa; vestiture not visible, except at apex, where 
there are two minute tufts each side. Metasternum nearly flat, strongly 
divided at base, very sparsely but not coarsely punctate; first and second 
abdominal segments strongly convex, second and third with same punctua- 
tion except in posterior third or half, where the surface is impunctate. 
Last segment strongly and coarsely punctate except at apex and a small 
median area near base, which are finely and densely punctate. Femora 
glabrous. 
Length 8.5 mm. ( $ )-6.omm. (cT); width 3.9 mrn. ( $ )-2.5 mm. (cP).
