author feels that the terms postantennal process and postoral process, 

 as applied to the structures termed first and second maxilla by Wilson 

 (1907a), are noncommittal terms and should be used until the nature 

 of the two structures in question is better understood. To facilitate 

 the use of the thoracic-leg tables, a hypothetical thoracic leg is shown 

 in figiH-e 1, giving all of the component parts of the armament of the 

 tlioracic legs discussed in tabular form in the paper. Further, a 

 table of the hypothetical thoracic leg is given in table 1. 



The names of previously reported hosts and the hosts from which 

 the Hawaiian specimens w^ere collected are those given by Bigelow, 

 Schroeder and Farfante (1948) or by Goslme and Brock (1960).

Material.— Seven adult females taken by the author from the

 Bay, Oahu, Hawaii. Of these 7 specimens, one (USNM 110799) has 

 been designated as the holotype and the rest (USNM 110800) as 

 paratypes.

Diagnostic description of female. — Cephalothorax (fig. 2a) 

 ovoid, consisting of cephalic, maxilliped-bearing and first pedigerous 

 segments. Anterior cephalothoracic margin flatly rounded, curving 

 sharply laterally, sharp lateral curve continued posteriorly as dis- 

 tinct line separating raised median cephalothoracic region from 

 narrow, winglike lateral regions. Lateral regions terminating pos- 

 teriorly in small, lobate extension marking posterior outer corner of 

 small, irregular sinus. Apex of sinus giving rise, ventrally, to single.
