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 large and distinct Corylophus, being one of the most truly indigenous of the Coleopterous inhabitants of these islands,—and receding, as has been already mentioned, from the generic type in being apterous. [...] It is exceedingly rare, or at any rate local, being confined to the dense ravines of intermediate and lofty altitudes,—where it is usually to be met with amongst the rankest vegetation and in the dampest spots. Thus, during the summer of 1850, I brushed it from off wet fern in the almost inaccessible region of the Lombo das Vacas, in June ; as also, under similar circumstances, at the Lombo dos Pecegueii-os, in July ; and at the Ribeiro Frio, by the moist edges of the Levada, in August.’
