96 MADEIRAN COLEOPTERA. 
chestnut trees, at the Mount (above Funchal), during May 1856. It 
is allied to the European 7’. Laricis, but is somewhat shorter and 
broader, much less pubescent, and with the spines at the truncated 
apex of its elytra considerably smaller: its tibie also (especially the 
four hinder ones) are less powerfully armed along their outer edge. 
The specimens in the British Museum were presented by their captor, 
Mr. Bewicke.

Inhabits Madeira proper, occurring sparingly beneath bark (for the 
most part of chestnut-trees) below the altitude of about 2500 feet. 
263. Tomicus Dohrnii. 
Tomicus Dohrnii, Woll., Ins. Mad. 290 (1854). 
Inhabits the sylvan districts of Madeira, principally at high ele- 
vations. 
264. Tomicus perforans, n. sp. 
T. cylindricus nitidissimus fusco-ferrugineus et minus pilosus, pro- 
thorace amplissimo subtiliter et parcius punctulato, mox ante me- 
dium subnodoso-convexo, antice dilatato obtuse rotundato necnon 
mucronibus asperato, elytris levissime seriatim punctatis (seriebus 
alternis vix observandis), ad apicem leviter oblique truncatis. 
Long. corp. lin. 11. 
T. closely allied to the 7’. Dohrnii, but perhaps a trifle larger and 
broader, paler in hue, less pilose, and very much more highly 
polished. Prothorax somewhat longer than in that insect, being 
even more developed in front,—so that the convexity on its disk is 
more medial (being but very slightly before the middle); more 
distinctly punctulated behind (the punctures however being even 
more remote), and very much brighter,—there being no appear- 
ance beneath the microscope of the minutely subgranulose strue- 
ture which causes the surface in that species to be almost opake. 
Elytra as in the 1’, Dohrnii, but a trifle shorter and less parallel ; 
with their interstices somewhat broader; the punctures down the 
interstices fewer and more distinct; and with the granuliform 
spinules at the apex (which is perhaps a little more truncated) 
less minute. 
Inhabits the wine-stores of Funchal, feeding on the bungs of the 
casks. It was first pointed out to me by Mrs. Phelps, during the 
summer of 1855, who stated that it was at times exceedingly
