To grasp what has been done by him an examination must be made of the entomological journals for the last forty years, for there he is generally in evidence. In the proceedings of the Entomological Society of London Mr. Bignell's name is quoted as being the discoverer of fifty-one parasites, nineteen being new to science and thirty-two new to Britain. In recognition of this work, one of the new species has been named after him _Mesoleius Bignellii_. The Royal Cornwall Polytechnic Society have awarded him three of their medals, a bronze one for "land and fresh water shells," a silver one for a "collection of British moths," and a second silver medal for "butterflies and moths." In the publications of the Ray Society on the _Larvæ of British Butterflies and Moths_, at the end of each volume we find a list of parasites preying on these beautiful insects, "kindly prepared by Mr. G. C. Bignell, F.E.S." One of the most extraordinary features of Mr. Bignell's work is the infinite delicacy wherewith even now at an advanced age he is able to draw and colour his specimens. The miniature painter of a beautiful girl's face a century ago did not take more pains to delineate the object of his admiring study than does Mr. Bignell to obtain a "counterfeit presentment" of some disgusting caterpillar or parasitic insect. The hunting for specimens would be an exhausting toil were it not a labour of love. On one occasion Mr. Bignell obtained one hundred and forty-one caterpillars of a certain moth in Whitsand Bay, under Fort Tregantle. They were feeding on henbane, and as he did not know where else to get the right sort of food for them, he had to go out two or three times a week for the food, walking in all a hundred miles. But, alas for the ingratitude of the caterpillars, not a single moth rewarded all this devotion! Yet even this was outdone by a hundred and thirty-five mile walk in the dark to attempt to capture one sort of moth, which perhaps deserves to be mentioned for its elusive ways. It is called the _Dasycampa rubiginea_, and has to live up to its name. Plym Bridge was supposed to be its haunt, and its time of taking its walks or flutter abroad, night, and that also in midwinter. So night after night in November and December it was stalked, till one night, between the 6th and 7th December, the moth was spotted leisurely sipping honey from the flowers of the ivy growing on one of the pillars of the old gateway leading into Cann Wood between Plym Bridge and Plympton, just as the clock at Morley House was striking twelve.
