defined, straight carina, margin sinuate, disc conv'ex, a median depression near 
the apex, lateral oblique depressions feeble, surface transversely strigose and 
punctate between the strigfe ; scutellum transversely carinate; elytra slightly 
sinuate behind the humeri, feebly dilated behind the middle, apices rounded and 
serrulate, disc slightly depressed, a very vague costa each side, basal depression 
moderate, on each side, within the costa, are three t)nbescent spots, OTie at base, 
an elongate spot in front of middle, a smaller oval spot one-third from apex, 
usually also a small spot exterior to the costa near the end of the middle spot, 
surface rather closely imbricate-granulate : body beneath more shining than 
above; prosternal lobe rather deeply emarginate, intercoxal process parallel be- 
tween the coxjE, acute at tip, propleurse closely punctate; metasternum at sides 
densely and rather finely granulate-punctate. Abdomen sparsely finely punc- 
tate and alutaceous, a much denser spot of punctuation at the side of the third 
segment; suture between the fir.st two segments evident at the sides, vertical 
portion of segments not conspicuously pubescent; pygidium coarsely punctate, 
carinate at middle; claws cleft near the middle, forming a broad tooth. Length 
.'24 — .32 inch. ; 6—8 mm. 
Male . — Front usually green, more densely punctate; prosternuin 
densely punctured and pubescent, anterior portion of nietasternum 
hairy ; anterior and middle tibite distinctly mucronate ; first and 
second ventrals rather roughly granulate at middle. 
Female . — Front less closely punctate, ajneous or cupreous; jtro- 
sternum more shining, not hairy; tibim not mucronate; ventral 
segments simply punctate. 
Variations . — No variation of moment has been observed. Badly 
preserved s|)ecimens are often without spots, but the elongate narrow 
form of the insect will make it easily known.’ 
This species is especially notable in the long slender legs. The 
hind tarsi are especially elongate, being longer than the tibia, the 
first joint longer than half the tibia. 
Habits . — Found on the foliage of Oak shrubs. 
Hah . — Massachusetts westward to Illinois, south to N. Carolina. 
A. scitiiliiM u. sp. — Form oi fallax ; head aud thorax brassy, elytra dark 
olivaceous, with pubescent spots as in ohsoleto-gnttatus. Antennae slender, reach- 
ing the hind angles of the thorax, serrate from the fourth joint, more or less 
teneous; head viewed from above slightly convex, front with a broad, but shal- 
low depression i)unctate aud obliquely strigose, occiput longitudinally strigose, 
front beneath pubescent, a transverse carina at base of clypeus. Thorax a little 
wider than long, sides irregularly arcuate, hind angles rectangular, with a sharp, 
straight carina, margin sinuate, disc coTivex, a faint ante-scutellar depression, 
another more faint near the apex, lateral oblique depression moderate, surface 
shining, transversely strigose at middle, obliquely at the sides, finely punctate 
between the strigse, a narrow pubescent area along the side; scutellum trans- 
versely carinate; elytra sinuate behind the humeri and somewhat broadened 
behind the middle, apices rounded and serrulate, disc slightly flattened at middle
