106 Mr. T. V. Wollaston on Additions to Madeiran Coleoptera. 
The present insignificant little Trogophlwus, a single specimen 
of which I have found amongst some insects collected by Mr. 
M. Park near Funchal, is apparently as small as the minute 7’ 
simplicicollis, with which, in its very dense and fine sculpture, it 
nearly agrees. Nevertheless its paler limbs and totally different 
prothorax (which is not narrowed behind as in that species, nor 
free from longitudinal furrows) will of themselves at once sepa- 
rate it therefrom; whilst from its still nearer ally, the 7. corti- 
cinus, it is easily distinguished by its smaller size and closer and 
very much finer punctation, as well as by its more obsolete 
prothoracic fovez, and by the paler hue of its legs and the basal 
half of its antenne.

Philorhinum humile, Kraatz, Nat. der Ins. Deutschl. ii. 966 (1858). 
P. linear, depressed, black, slightly shining, and clothed with 
a short, decumbent, cinereous pile. Head, prothorax, and elytra 
rather more piceous, or diluted in colouring, than the abdomen, 
and densely, deeply, and equally punctured throughout: the 
first subtriangular, with the eyes prominent, and the second 
transverse-subquadrate, being nearly equally rounded at the 
sides. Antenne fusco-ferrugimous towards their apex; their 
base and the /egs diluted testaceous. 
The abbreviated elytra, leaving jive segments of the abdomen 
visible, and the elongated basal joint of the hinder feet, will 
of themselves at once distinguish the genus Philorhinum from 
its immediate allies. The single individual described above, 
identified by Mr. Janson with the common European P. humile, 
with which it appears in every respect to agree, was de- 
tected by Mr. Bewicke at 8. Antonio da Serra (in Madeira 
proper) during the summer of 1859. In the English specimens 
which I have examined, the males seem to have their antenn 
a trifle longer than those of the females, and with the apical
