OF WASHINGTON. 175 
extending from apex to near base, sometimes only half as long, rarely 
but slightly indicated; lateral vittae sinuate, narrower than median, their 
most elevated portion showing in a very irregular much interrupted 
shining black line ; surface of vittae very coarsely, irregularly, rather 
sparsely, punctate, intervals still more coarsely sparsely punctate; a 
large shallow fossa each side of the apical half of the thorax and a simi- 
lar deeper fossa each side of the base. There is usually an indistinct 
branch of the lateral vittse. Scutellum opaque or subopaque, channeled. 
Elytral surface comparatively even, with obscure punctuation. Striae 
moderately, deeply, coarsely and remotely punctate, about 12 punctures 
on the sutural and next three striae, so closely placed as to form at the 
base four small shallow fossae between alternate intervals; intervals 
very irregular owing to the large elytral punctures, alternately very 
slightly elevated, elevated intervals closely uniseriately punctulate, the 
others half as closely punctulate, the third with a tendency to produce 
2 rows of fine punctures. Pygidium rather coarsely, deeply and sparsely 
punctate, with short golden yellow hairs and short lateral apical tufts. 
Lower surface very coarsely, sparsely punctate, at the sides scarcely 
different from the middle and the lower surface of the thorax; second, 
third and fourth ventral more finely, apex of last segment densely and 
coarsely punctate. Anterior tibiae with inner apical tooth moderately 
long, subapical less than half as long and obtuse. Third joint of tarsi: 
anterior and middle about one-fourth or one-fifth wider than the first joint, of 
posterior tarsi scarcely wider. 
cT. Pygidium subquadrate. Ventral concavity broad and very shallow. 
9. Pygidium distinctly narrowed to rounded apex. Metasternum, 
first and second abdominal segments flat, the last two connate or nearly so. 
Length 7.0 9.5 mm., width 3.2-4.0 mm.

At first sight this species might be taken for an aberrant 
form of zecz,- and this applies particularly to large individuals, 
but it is more nearly related to callosus, and occupies a position 
about midway between these two as regards the thoracic 
pattern. A somewhat striking character is the distinctness 
of the four thoracic and six basal elytral fossae in clean well- 
marked individuals and the coarsely punctate elevated lines 
of the vittse. The smallest individuals seen, e. g., the eastern 
ones, are less strongly marked than the typical Texas and 
Kansas examples, approaching callosus in the sculpture of the 
thorax but differing by being proportionately stouter. 
This species has been reported as quite injurious to corn
