Carapace: rich reddish brown, almost black around eyes; a broken white stripe extends on each side from ALE to posterolateral corner and down to posterior border; a few white scales along ventral margin; central part of clypeus between AME without whitw scales which extend as a tuft beneath AME and over front surface of chelicerae and, less conspicuously, laterally along cheek region. Abdomen: dark reddish brown at base; then a series of light and dark bars on dorsum best shown in Figure 217; thus nine distinct dorsolateral bars; venter dull brown.

The Peckhams had a single male from Panama sent to them by Count Keyserling. So far as I know, the species has not been collected since that time. It has not yet appeared in my collection. I have a single male from the Canal Zone Biological Area, Aug., 1939, which I have tentatively assigned to this genus. It is a damaged specimen and will not be described in this paper. When better specimens are available it will certainly have to be described as a new species and possibly will be the basis of a new genus.
Genus Beata Peckham, 1895
Professor Petrunkevitch ('25) considered that six species of the genus Beata were known at the time of his paper on Arachnida from Panama. He gave a detailed description of the female of B. magna
