183. Lathridius ruficollis*. 
L. elongatus angustus, capite prothoraceque rufescentibus subpunc- 
tato-rugosis, hoc angustiore subconvexo, nec ad latera nec ad an- 
gulos anticos ampliato, ad basin transversim constricto, elytris 
profunde seriatim punctatis (punctis maximis sed in seriebus plus 
minus irregularibus dispositis), sutura interstitiisque leviter ele- 
vatis.

LL. small, elongate, and narrow. Head and prothorax rufescent, and 
rugosely punctured and wrinkled: the former unchanneled: the 
latter narrow (especially behind), and rather convex, not being 
flattened at the sides; with a straightened transverse constriction 
posteriorly, between which and the anterior angles (which are not 
outwardly flattened, or developed) it is rounded. lytra with the 
sides rather parallel about the middle, and, although rounded at 
the shoulders, with the humeral angle itself (or ridge) somewhat 
porrected and acute ; deeply seriate-punctate, the punctures being 
very large, but somewhat unevenly disposed,—causing the inter- 
stices (which, with the suture, are slightly elevated) to be more 
or less irregular (or waved), especially towards the base, and the 
surface consequently to present a rather rugulose, or reticulated, 
appearance. Limbs pale rufo-ferruginous. 
An insect pretty generally distributed throughout Europe, and de- 
tected during the autumn of 1855, by Mr. Bewicke and myself, in 
the south of Madeira proper,—where it was tolerably abundant be- 
neath the dead bark of some old palings, surrounding a hay-stack, 
on the hills immediately above Camacha: and some specimens have 
been recently communicated to me by Mr. Mason, taken from amongst 
the dried plants which he had collected in the island. It is the un- 
doubted Corticaria ruficollis of Marsham, an insect which was erro- 
neously referred by Mannerheim to the Latridius constrictus of Gyl- 
lenhal.
