200 MR. A. MURRAY'S MONOGRAPH OF THE FAMILY OF NITIDULARLE. 
basi utrinque oblique sinuato, angulis posticis rotundatis; elytris thorace parum 
longioribus, humeris prominentibus; antennis pedibusque ferrugineis. Long. 24 lin., 
lat. 1i lin. 
Habitat in California. 
Oblong-square-shaped, more particularly the elytra, convex, thickly punctate, clothed 
with cinereous pubescence; black, or sometimes with the elytra more or less reddish 
brown, the sides, the base, and the suture around the scutellum being black. Antenne 
with the club not very thick. The thorax with the base extending back in the middle 
like a broad lobe and obliquely sinuate on each side, disk sinuate behind on each side of 
the lobe, sides straight behind and narrowed in front, the angles rounded. "The posterior 
lobe is more developed in some specimens than in others, and gives a different aspect 
to the insect according to whether it is closely applied to the base of the elytra or 
separate and with the head and thorax bent down. Scutellum small. The elytra only 
a little longer than the thorax, shoulders prominent. The penultimate dorsal segment 
of the abdomen with very distinct fimbrie.  Pygidium large, sinuate, and acuminate. 
Antenne and legs ferruginous. 
From North-west America—apparently found all along the coast from Sitka, whence it 
was first received by Mannerheim, to San Francisco in California, Mr. Hepburn having 
sent me specimens from that neighbourhood. 
First made known by Mannerheim, who referred the species to the genus Strongylus 
with doubt,—as he says, from not being acquainted with the genera Brachypeplus, Colo- 
pterus (Erichson’s first published name for Colastus: see Wiegmann's Archiv, 1842), or 
Cilleus, to some one of which he seemed to think it might be referred, he retained it 
under Dejean’s large genus Strongylus as most likely to cover it. I have seen a typical 
specimen from Mannerheim himself in Professor Boheman's collection, which enables 
me to allot it with certainty to its proper place. 
24. BRACHYPTERUS FERRUGATUS. 
Br. tincto affinis. Differt clava antennarum minus dilatata, elytris parum brevioribus, 
creberrime punctatis, minus nitidis. Totus ferrugineus, interdum partibus obscurior. 
Long. 21 lin., lat. 1 lin. | 
Habitat in Oregon. 
Allied to B. tinctus, but distinct. The antennsz are almost without a club, the last 
three articles being only a very little and gradually thickened, the whole having a monili- 
form appearance. Elytra rather shorter than in B. tinctus. It is wholly ferruginous, 
but specimens occur with the head and thorax and the vicinity of the scutellum dark. 
The punctuation is very close and deep, and the whole surface is clothed with a light 
flaxen-coloured long pubescence. 
Found in Oregon by Mr. Jeffrey, the collector sent out in 1850 by the Edinburgh 
* Oregon Botanical Association” to collect plants and seeds in British Columbia, Oregon, 
and California.
