a beetle very similar to the preceding in its shape and habits, ap- 
pearing in July end August, .45 to .75 long, of a black color, its 
thor&X nearly circular and clothed with white hairs, with a smooth 
polished black Hue in its center, and a callous-like spot on each side 
of it, and its wing-covers with very coarse, shallow confluent punct- 
ures and some downy whitish spots, forming two irregular bands near 
the middle. 
This species is supposed to have been introduced in its 
larva state in timber from Europe, and is found in our 
country only near the sea coast. (Harris 7 Treatise, p. 88.)

Ortho8oma brunueum De Geer. 
Order Coleoptera ; family Cerambycidje. 
A flattened long-horned heetle, 1.00 to 1.30 long, and 
less than a third as broad, with its opposite sides paral- 
lel, its thorax twice as hroad as long, and with three 
sharp teeth on each side, its wing-covers withtwo or three 
slight elevated lines, its antenna? scarcely as long as the 
body, and its color chestnut red, darker anteriorly 
Two dozen or more of the grubs were taken, 
May 26, by Mr. Calder and myself from a very 
soft, rotten pine stump ; up to June 24 they 
had not pupated in confinement, but by the 5th 
to the 8th of July one of them became a pupa. 
Mr. Calder has also found the fully grown 
larvae in August in maple logs at Warwick, R. I., and in the rotten 
wood of another deciduous tree. So that it appears that this beetle 
lives indifferently in the soft, decayed logs or stumps both of hard and 
coniferous trees. 
Larva. — Described while alive. Body cylindrical, not flattened, the segments very 
distinct, as the sutures are deeper than usual : head moderately hroad : prothorax 
large and hroad and rather long, being 9 mm broad and 4£ mm long ; surface rough on 
the posterior two-thirds. On each of the first to seventh abdominal segments is a 
transverse oval cylindrical fleshy area, each with three transverse folds, the area on 
the seventh ring being nearly twice as long (antero-posteriorly) as that on the first, 
the areas becoming longer and narrower, i. e., more rounded, goiug backward towards 
the seventh segment ; the end of the abdomen smooth and shining ; each thoracic 
segment with a pair of slender three-jointed feet. Length, 35 ,nm (1± inches). 
In addition to the description on p. 161 of Bulletin 7, the following 
characters may be noted : 
Head about one-half as wide as the prothorax. Front edge of epicrauium rough, 
black, with a spine on each side below, projecting over the clypens (" epistoma '' of
