1. Jordanthribus planifacietus Zimmerman ,

B. P. Bishop Mus., 0cc. Papers 14 (13): 237, figured, 1938 ( fig. 1 , a, b; pl. 1, B).

This species is smaller and conspicuously paler in color than is J. conspersus . The more salient differences are summed up in the synoptic table, and a detailed description is given in the paper cited above. Length, 1.75-2.25; breadth, 0.8-1.0mm.

Seven specimens representing both sexes of this peculiar species were collected at Machanao by Usinger, June 5, 1936; five of them were from dead leaves of a fallen tree, the other two were beaten from dried leaves of fallen branches; 22 specimens from the National Museum were found by Oakley on Pandanus leaves, Dec. 30, 1938, no. 38-9035.

In southeastern Polynesia I found this species on dead banana leaves and coconut fronds and swept it from low herbage. Its widespread distribution indicates that the species has been artificially spread by commerce.
