 CHICKERING: SALTICID SPIDERS OF PANAMA 267

legs yellowish with a few dorsal and lateral reddish brown spots, most marked on first pair of legs. Abdomen: generally yellowish white with reddish brown markings; dorsal area with a complicated pattern re- sembling somewhat the pattern represented by F. Cambridge for M. variegatus and M. expallidatus, difficult to describe accurately; lateral sides spotted with reddish brown, and on each side an oblique speckled reddish brown bar occurs in posterior third; venter with a broad, rectangular, central, deep reddish brown stripe from genital groove to tracheal spiracle, united laterally with oblique bar.

Type locality. Female holotype from El Valle, R. P., July, 1936. One paratype female from Boquete, R. P., July, 1939.

BEATA STRIATA Petrunkevitch, 1925

Professor Petrunkevitch had one female from Cerro Iglesia, R. P. I have had the privilege of examining the type in the collection of Pro- fessor Petrunkevitch, but the species has not yet appeared in my col- lection.

As pointed out in an earlier place, this species has been retained in the genus Beata with some hesitation. In the males in my collection the single retromarginal tooth on the fang groove is quite distinctly unidentate. In some females the tooth is fissidentate while in others it would be called unidentate. The species appears to be one in which the teeth are in an intermediate condition between the two types. At one time in the course of the study of this family I selected a female which showed the fissidentate condition in a fairly satisfactory way and intended to describe it as a new species. I am now satisfied that the specimen belongs to this species and I, therefore, am using it as a hypotype of which I give the following description:

Female hypotype. Total length 5.12 mm. Carapace 2.50 mm. long, 1.98 mm. wide a short distance behind PLE which occupy twenty-six thirty-firsts of the width of the carapace at that level, 1.22 mm. tall and, therefore, .61 as tall as wide; only slightly depressed from PLE to posterior steep declivity which begins about six thirteenths of the dis-
