Thomas Vernon Wollaston published this drawing in his book ‘Insecta Maderensia’ in 1854. In the book he thanks Westwood for providing the illustrations, ‘Particularly, however, would I draw attention to the valuable help which I have received from J. O. Westwood, Esq., whose pencil has been so elaborately employed in the figures which I am thus enabled to attach, and by whom many of the minutest of the dissections were accomplished, — with a degree of delicacy, moreover, to which I did not myself at the commencement of this Work (though I have since succeeded in anatomizing the larger portion of them, likewise) lay claim.’

Wollaston wrote the following about this species:

‘A very elegant and peculiar insect, [...] It is found, beneath stones, in most parts of Madeira, though seldom above the altitude of about 3500 feet. On the northern side of the island it descends to the sea-shore, but on the southern its range does not commence so low. It occurs very plentifully at times, making its appearance about the end of summer and lasting until the following spring. On the western slopes of the Pico do Cardo, near Funchal, in the Chestnut-wood in the vicinity of the Mount Church, as also in the north of the island, at the Passo d'Areia near Sao Vincente, on the level of the beach, I have myself captured it in considerable abundance. It seems to be a species peculiar to Madeira proper, it not having been hitherto observed in any of the other islands of the group.’
