EuCHiETA PUBESCENS. 



Feminae : — Cephalothorax pubescens, capite lateraliter angulatus, b-arti- 

 culatus, segmento postico perbrevi, subacute. Antennas anticce corpore 

 paulo breviores, quoad setas E. cominuniybre similes, setis antepenultimis 

 brevissimis. Pedes antici apiee 5-articulati et subelongati. Abdomen 

 k-articulatum, segmento primo secundum longitudine duplo superante. 

 Seta caudalis secunda ferme corporis longitudine, plumosa. 



Female : — Cephalothorax pubescent, the front on either side forming 

 an angle with the sides, and at middle acute, five-jointed, posterior 

 segments four, the last very short, subacute behind. Anterior 

 antennae a little shorter than the body, setae nearly as in the com- 

 munis, the antepenult setae both anterior and posterior, minute; 

 anterior feet having the apical portion somewhat elongated and 

 five-jointed. Abdomen four-jointed, first joint oblong, twice as long 

 as second, last very short j caudal setae straight, second about as 

 long as body, plumose.

Collected in the Paumotu Archipelago, Pacific, August 19, 1839, 

 latitude 15° 45/ south, longitude 144° 30' west. 



Length, one-twelfth of an inch. Colour, slightly yellowish red in 

 the posterior thoracic segments. 



The abdomen was but four-jointed, with some indication of a very 

 short basal segment. The first of the four segments was largest and 

 gibbous below. The long caudal seta is plumose. The anterior feet 

 have the long setae about ten in number, and very finely pectinate; 

 the five-jointed apical portion is more than a fourth the length of the 

 second joint. The basal joint bears a few spinous setae; on the second 

 the longer setae are finely pectinate, like the apical setae — the pectina- 

 tion is so fine as to require a very high power to detect it; the shorter 

 spines are more slender and numerous than in the communis.
