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:

‘This elegant little species, which is apparently the most truly indigenous, and constant in colouring, of all the Madeiran Coccinellae, may be at once recognised from the remainder by its smaller size and slenderer legs, by its more distinctly punctulated surface, and by the peculiarity of its markings,—the form of which will be best understood by a reference to the Plate. It is exceedingly rare, and confined to lofty altitudes,—where it occurs, solely (so far as I have hitherto observed), on the Genista scoparia, or common Broom, which clothes the uplands in many of the elevated districts of the island. I first detected it on the Paul da Serra, July the 3rd, 1850 : and I subsequently met with it at the Cruzinhas ; as also (during August) on the Enciuniado exactly opposite to the Pico Fuivo (on the descent from the latter towards Santa Anna),—about 6000 feet above the sea.’
