areas between the ocelli and the eyes are liglE, often partly enclosed 
by a black circular line and with a heavy black spot in the middle. 
The reflexed portions of the front striated with dark. Pronotum, 
as in other forms, the markings smaller and more numerous. 
Elytra mottled with blue-green, the nervures somewhat fuscous, 
claval sutures often broadly light. 
Reddish form — Reddish, pronotum and elytra mottled with 
creamy, anterior margin of pronotum and scutellum distinctly red- 
dish, dark markings often obscure or wanting, the outer pair of 
lines on vertex often enlarged, somewhat lobed.

Stouter than even the preceding varieties, elytra usually long 
nearly parallel margined. Dark testaceous, shading to fuscous, 
elytra slightly and obscurely mottled. Vertex and scutellum fus- 
cous, a few of the light markings of uhleri persisting, as follows: 
a dash back of the apex of vertex, three lines on the disc, a trans- 
verse spot at base and a margin next the eyes. Often light mark- 
ings on pronotum, the lateral ones arranged in rows, apex of scu- 
tellum light. The face is usually light, with dark mottlings. Ely- 
tra often with the mottlings arranged in light stripes, especially 
along costa and claval suture. 
This species, as a whole, is very variable in size and color, 
and recalls 0. undata and lateralis in their red, green and 
black forms. The varieties readily fall into two series on 
structural characters. The first has hieroglyphica , and dolo- 
brata as the extreme in darkening up. These forms are the 
only ones found in the Mississippi valley and as far west as 
central Kansas ; they occur also in Texas, Arizona and Mexico. 
The second series has uhleri as the common form, and con- 
iluens as the dark extreme. The uhleri is the common 
form in Wyoming, Colorado, Arizona and New Mexico, and 
extends westward to the coast. The specimens from the 
western coast, including Idaho, are much larger, and have 
longer elytra, and are mostly confluens. 
Specimens of this species are at hand from Illinois, 
Iowa, Missouri, Nebraska, Kansas, Arkansas, Texas, Wyo- 
ming, Colorado, Utah, New Mexico, Arizona, Idaho, Wash- 
ington, Yancouvers Island, Oregon, California and Mexico. 
All specimens received as hieroglyphica from points east of 
Illinois belonged to the following species:
