Excerpt from Entomological News and Proceedings of the Entomological Section of the Academy of Natural Sciences of Philadelphia, 1903, Vol. 15 Standards, of course, are absurd; there are none in such cases as this.

Excerpt from Entomological News and Proceedings of the Entomological Section of the Academy of Natural Sciences of Philadelphia, 1892, Vol. 3 The young larva when first hatched are also almost invisible, and, even after the first moult, look only like a small, colorless aphis on the leaf. The third moult shows a lilac mark in the centre of the dorsum increasing with the growth, until the last moult, when it resembles a rude maltese cross, of a pinkish or purplish brown, surrounded by a yellow border with a central square dot on the elipse-shaped pea-green larva.
