New York, Maine, Lake Superior. Closely resembles the preceding, but the thorax is 
more abbreviated, and distinctly dilated in front, the cost® of the elytra are narrower and 
less connected by transverse smooth lines, the colour is more coppery, and finally the pos¬ 
terior tibim are curved, especially in the males.

Middle and Southern States, rare. Differs from the following by the broader form 
and more densely punctured upper surface, as well as by the slightly unequal thorax, 
somewhat reticulated elytral costm and more finely serrate elytra. The species varies 
somewhat in the form of the thorax, and in the elytral impressions: in some specimens 
the former is scarcely one half wider than its length, and the disc each side of the dorsal 
groove is less punctured: on the elytra the anterior impression is usually a vague fovea, 
but is sometimes prolonged obliquely upwards and outwards; the posterior one is oblique 
and sinuate, sometimes not very distinct: the costae are narrow, and have a tendency to 
be connected by reticulations especially behind and outside of the posterior impression.

Western States: one male from Ohio, Dr. Schaum. The thorax is not all channeled, 
the punctuation is regular, and the elytral costce straight.

One specimen, Arizona. Related to the preceding, but differs by the punctures of the
