160 MADEIRAN COLEOPTERA. 
462. Helops cinnamomeus. 
Helops cinnamomeus, Woll., Ins. Mad. 520. tab. xii. f. 8 (1854). 
Inhabits Madeira proper, occurring in dry spots of a low elevation. 
463. Helops pallidus. 
H. eylindrico-oblongus convexus pallido-testaceus subnitidus, pro- 
thorace confertim punctato basi paulo attenuato, elytris leviter 
crenato-striatis, interstitiis minutissime punctulatis, 
Long. corp. lin. 34-5. 
Helops pallidus, Curtis, Brit. Ent. vii. 298 (1830). 
H. cylindric-oblong and convex, pale-testaceous (the eyes alone being 
dark), and slightly shining. Head and prothoraw rather closely 
and distinctly punctured: the (latter transverse-quadrate, and a 
little narrowed behind,—where it is almost as broad as the base 
of the elytra. Hlytra lightly crenate-striated, and minutely punc- 
tulated all over, the punctures being very much smaller and 
shallower than those on the prothorax. 
Detected by myself (at a considerable depth beneath the surface) 
on the sand-hills, behind the sea-beach, of Porto Santo, during May 
1855,—at the roots of Arundo dona, and the few other plants 
which flourish in that locality. The specimens are just perceptibly 
less shining than our British ones, are a trifle more closely punc- 
tulated, and have their prothorax not quite so much narrowed behind ; 
but I cannot regard these minute and unimportant differences as 
of more than geographical significance. It occurs in the maritime 
and subsaline districts of central and southern Europe, as also in the 
north of Africa.
