the two impressed spots. These are the Violet-colored Calli- 
dium, C. janthinum of Dr. Le Conte, and of Dejean’s Catalogue. 
But individuals appear to occur of all intermediate varieties, 
and I am therefore inclined to think they can scarcely be re¬ 
garded as constituting two distinct species. 
238 - Porter Hylotrupes, Hylotrupes bajulus, Linnseus. (Coleoptera. Ceram- 
bycid®. 
A beetle very similar to the preceding in its shape and habits, 
appearing in July and August, 0.45 to 0.75 long, of a black 
color, its thorax nearly circular and clothed with white hairs, 
with a smooth polished black line in its center and a callous- 
like spot on each side of it, and its wing covers with very coarse 
shallow confluent punctures and some downy whitish spots 
forming two irregular bands near the middle. 
This species is supposed to have been introduced in its larva 
6tate in timber from Europe, and is found in our country only 
near the sea coast. See Harris’ Treatise, page 88. 
239 . Pennsylvania Prionus, Orthosoma Pennsylvanica, De Geer. (Coleop- 
tcra. Ccrambycid®.) 
A flattened Long-horned beetle, 1.00 to 1.30 long, and less than 
a third as broad, with its opposite sides parallel, its thorax 
twice as broad as long, and with three sharp teeth on each side, 
its wing covers with two or three slight elevated lines, its an¬ 
tennae scarcely as long as the body, and its color chestnut red, 
darker anteriorly. Appearing from the beginning of July till 
into September, often entering open windows on warm evenings, 
and, as it flies, repeatedly hitting against the ceiling over head 
with a sharp click, and making a crashing kind of noise when it 
alights. 
The larvae which I suppose to be this species, but which I 
have never been able to succeed in rearing to its perfect state, 
is common under the bark of pine logs, and is a white, flattened, 
soft worm, scarcely three times as long as broad, slightly taper¬ 
ing from before backwards, its jaws or mandibles black, stout 
and tapering to a very sharp point, the two first rings of its 
body larger than the others and of a horny substance, the first 
of these rings longer that the. second, tawny yellow, with a
