Empicoris rubromaculatus McAtee and Malloch, Proc. U.S. Nat. Mus., LXVII, I, p. 16, 1925. 



Savaii :— 1 specimen, 1,000 ft., 21. xi. 1925. 



Recorded from California, Missom'i, Florida, Virginia, Porto Rico, Brazil 

 (Madeira ?), N.S. Wales, New Zealand, Fiji and Hawaii. 



The variety recorded by McAtee and Malloch from Madeira is probably 

 identical with Ploiariola scotti Distant. (Seychelles). 



51. Empicoris, sp. 



This species is apparently closely allied to the Fijian E. calamine Kirk., 

 but differs in the more or less regular fuscous annulation of the first antennal 

 segment and hind femora. It has been thought best not to base a new species 

 on a fragmentary specimen.
