Tarphius Lowei, Woll., Ins. Mad. 134. tab. iii. f. 5 (1854). 
Inhabits Madeira and Porto Santo, being rare in the former, but 
abundant in the latter. It is more particularly attached to various 
kinds of lichen,—whether growing in the fissures of the rocks (as in 
Porto Santo), or on the trunks of trees.

Inhabits the sylvan districts of Madeira proper. A correction is 
required in the description of this species, as given in the Jnsecta 
Maderensia. I there stated that the four anterior tarsi of the males 
are simple,—the hinder ones alone having their basal joint pro- 
duced on the under side into an elongated process. An examination 
of additional specimens has since convinced me that the front pair 
likewise have this primary articulation more or less lobed beneath ; 
and, moreover, that there are rudiments of a similar structure (never 
liable, apparently, to a further development) even in the intermediate 
pair also. The anterior feet, however, would seem to be subject to 
variation, in this respect,—the under spiniform projection being con- 
siderably more expressed in some specimens than in others. It was 
to an eatreme example, in which the fore-tarsi happened to be power- 
fully armed, and which was a little less parallel in its outline than is 
usual, that I originally gave the name of spinipes,—a species which, 
in the present Catalogue, I have suppressed. 
I cannot but admit the possibility, however, that two species may 
still be indicated under the 7’. inornatus, as now defined; for nearly 
all the specimens which I have taken in the south of Madeira (where 
it occurs, for the most part, beneath the bark and chippings of fir- 
trees on the mountains above Funchal) have their antenne just per- 
ceptibly shorter and darker than those from the interior and north of 
the island; whilst it is a remarkable fact, that I have not as yet 
observed (what I believe to be) the male sex except in the strictly 
sylvan regions,—where it is as common as the female. Nevertheless, 
as this non-detection of the males in the pine-woods of the south 
may have been an accidental circumstance (seeing that I have not 
more than thirty examples at present before me, from such positions, 
to judge from), and since in other respects the individuals from the
