In species in which liright colors, presumably because of pig- ment in the cuticle, make up the pattern, observed differences are usually reliable. As males are generally lighter colored than females, they are usually more variable and more difficult to separate on the basis of this character. A possible cause of error in separating Neoscona by coloration is variation result- ing from uneven preservation. If the alco- hol has been changed often, more pigment may be removed than if there are long delays between changes, and significant differences in the coloration of specimens may result. Ventral abdominal pattern. Character- istically, iJie ventral pattern consists of an area of black bordered by white, roughly forming a square with the epigastric furrow as the anterior edge (Plate 3). The differ- ences observed are too inconsistent for use, in separating species. Furthenuore, in adults the pattern is often faded and in- distinct, although in juveniles it tends to 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 Harvard University.
