Whether spiders prefer flowers colored like themselves is an unsettled question ; at any rate, Misu- menas of all colors and both sexes have been found on white flowers. Occasionally individuals are found on flowers of exactly the same color as themselves ; for example, deep yellow M. aleatoria on the wild indigo, Baptisia tinctoria, and the reddish M. asperata on the flowers of sorrel, Rumex acetosella. The adult fe- males of vatia and aleatoria are easily mistaken for each other.

Asperata is perhaps the most common species. The female seldom grows as large as the others, and does not lose entirely the red markings of the abdomen and legs. The scattered stiff hairs also distinguish it from the others. The males of the different species are distinct enough one from the other, though they differ widely from the females. The shape of the head and the markings around the eyes are much the same in both sexes, and by these males and females of the same species may be Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Emerton, J.
