Habits. — Not rare on Oak foliage, logs, stumps, etc., July ; INIas-sa- 
cliusetts (Blanchard, “ Ent. Am.” v, p. 32). Taken on White Oak, 
June (Tolman, ‘‘ Insect Life,” i, p. 343). 
I[(ib. — Occurs from Maine westward to the Rocky Mountains, and 
south to Texas. 
.4. gran 111 at us Say. — Form rather slender, color bra.ssy bronze, each ely- 
tron with three indistinct pubescent spots — basal, median and ante-apical, the 
first often wanting. Antennte slender, nearly reaching the hind angles of the 
thorax, serrate from the fourth joint, slightly greenish ; front rather flat, occiput 
with a linear impression extending to the middle of the front; surface coarsely 
closely punctate, occiput slightly strigose. Thorax wider than long, scarcely 
narrowed at base, sides regularly arcuate, lateral margin faintly sinuous, disc 
convex with three depressions, the one larger in front of scutellum, the two 
others in front on each side of middle less distinct, or even absent, the lateral 
oblique inqn-ession well marked, hind angles with a well defined, arcuate carina; 
surface transversely strigose, punctate in front; scutellum transversely carinate ; 
elytra feebly sinuate behind the humeri, slightly broadened behind the middle, 
apices acute, serrulate; disc slightly flattened at middle, the sutural margin 
elevated behind the middle, basal foveas moderate, surface rather coarsely im- 
bricate; body beneath darker than above ; prosternal lobe emarginate, the inter- 
coxal process rather broad, parallel, acute at tip, the propleurse with the entire 
side of body densely clothed with yellowish pubescence. Abdomen not very 
closely punctate, the sides of each segment with a more densely punctured spot 
clothed with pubescence, the vertical portion of the segments, except the second, 
densely imbesceut; pygidium coarsely punctate, with a strong median carina, 
which projects at tip; claws dissimilar in the sexes. Length .30 — .35 inch.; 
7. .5 — 9 mm. 
Male. — Front somewhat greenisli. Prostermim quite densely 
punctured between tlie coxte, more sparsely in front; first ventral 
segment longitudinally impressed with a smooth median line, second 
segment more deeply impressed, the impression smooth and extending 
nearly to the suture; anterior and middle tihiie feebly nuicronate, 
the posterior simple ; anterior and middle claws almost bifid, being 
cleft at the tip, posterior claws broadly toothed. 
Female. — Front cupreous. Prosternuin coarsely jiunctured be- 
tween the coxie, much smoother in front Ventral segments simple ; 
tibim sinqile; claws broadly, but acutely toothed on all the feet. 
Variations. — In all well preserved specimens there will be obsei'ved 
a line of pubescence extending from the front angles of the thorax 
to the base, passing inside of the carina. The pubescent spots of the 
elytra are at most faint, and are easily removed by abrasion, but their 
position is always indicated by a small and more densely punctured 
area. The three discal impressions of the thorax are variable. The
