102 MADEIRAN COLEOPTERA. 
griseous pile. Rostrum short, deeply punctured, and longitudinally 
strigulose. Prothoraw deeply and regularly punctured, rounded at 
the sides, and with indications of a slightly raised central line be- 
hind. lytra rugulose (the punctures being somewhat obliquely 
impinged, so as to cause their anterior edges to be a little promi- 
nent); very obscurely striated, but seriate-punctate,—the alter- 
nate rows being composed of smaller punctures ; the sutural line 
a trifle darker than the rest of the surface. Antenne short and 
robust, and with their club paler. Legs brownish-piceous. 
Detected by myself, during May 1855, at the roots of various 
plants (especially the Arwndo donav) on the sand-hills of Porto Santo, 
at a considerable depth beneath the surface. 
Genus 119. CAULOTRUPIS. 
Wollaston, Ins. Mad. 308. tab. vi. f. 6-9 (1854). 
279. Caulotrupis lacertosus. 
Caulotrupis lacertosus, Woll., Ins. Mad. 309. tab. vi. tf. 6 (1854), 
Inhabits Madeira and the Dezerta Grande,—occurring beneath the 
bark of trees (and in rotten wood) in the damp sylvan regions of the 
former, and at the stems of shrubby plants on the extreme summit 
of the latter. 
280. Caulotrupis lucifugus. 
Caulotrupis lucifugus, Woll., Ins. Mad. 310. tab. vi. f. 7 et 9 (1854). 
Inhabits all the islands of the group, adhering to the undersides of 
stones, and to the stalks of low shrubby plants, in exposed, windy 
spots. In Madeira proper it is rare, where the specimens (var. a) 
have their elytra rather evidently striated and subrugulose, and gene- 
rally with a slightly seneous tinge. On the Dezerta Grande (var. () 
it is likewise scarce ; and has its prothorax a little less closely punc- 
tured than in Madeira proper, its rostrum somewhat more densely 
(and roughly) so, whilst its elytra are not quite so distinctly striated, 
and are usually more free from an geneous tinge. In Porto Santo 
(var. y), where it is tolerably common on the mountain slopes, it is 
more lightly punctured still (its striz being nearly evanescent), and 
its elytra are, for the most part, more metallic than in any of the 
other varieties. On the Ilheo Chao (var. 6) it abounds, and presents 
nearly-the same modification as on the Central Dezerta, only it is a 
trifle more fusiform and shining, and its punctuation (at any rate of 
the rostrum) is perhaps a little finer. And, lastly, on the Southern 
Dezerta (var. ¢) it is thicker and more ovate than in any of the other 
islands, the punctuation of its prothorax and rostrum (the former of
