Dorsal tufts and ven-tral brush of anal segment long. Pupa. (Fig. 4.) — Essentially as in Culex. Thorax and cases forming a large elliptical mass, round which the slender, distinctly seg-mented abdomen curves, bearing a pair of anal paddles. Segments dorsally tufted with stellate hairs and some small tufts about the eyes and between the prothoracic air tubes.

The descriptions of new species in Walckenaer's Insectes Apteres fall into two classes : descriptions based on specimens, and descrip-tions based on figures. The former class are undoubtedly valid and I intend to accept them wherever I can apply them. Descriptions of figures, however, I hold, have no claim on the naturalist. Not only are they based on figures, but the figures have never been published. Many of the descriptions are sufficient for identification, but most are not. But no matter how complete, they are not descriptions of spi-ders ; but of figures of spiders. They rank with " hearsay evidence. ' ' I shall not use them nor list them ; I shall ignore them. The species Walckenaer described from specimens are usually marked with an "M," indicating, as he states, that the specimen was in the Paris Museum. In a few cases the type was in his own collection. In the following pages I have tried to identify such species that were de-scribed from the United States. The second volume of the "Aptdres' ' bears date of 1837, it should be as late as 1842 since there are refer-ences in it to 1 84 1. A number of species described by C. L. Koch in " Die Arachni-den " from the United States have never been identified by later arachnologists. Most of them can be easily placed ; a few are still doubtful.
