Holotype, female, USNM 2522, British West Indies, Vii-giii Gorda, 

 Prickly Pear Island, March 29, 1958, eT. F. G. Clarke, collector, 

 Berlese samplings of beach drift. 



Body length 20 mm. Pedal segments 53. Color head prehen- 

 sorial segment, and antennae pale yellow; pleura, tergites, stemites, 

 and legs yellowish white to white or colorless. 



Antennae (see also note E, p. 192) : Length 216 mm. Filiform, each 

 article much longer than wide (e.g., seventh, l:w=40:24). First 7 

 articles less setose than 8-14. Ultimate article at tip on outside witli 

 a long groove in which are 10-12 hyaline, spatulate setae; without any 

 other apparent special sensilla on this article or the other articles. 



Cephalic plate : Length 0.75 mm., greatest width 0.57 mm. Sides 

 slightly bowed outward, barely converging posteriorly; posterior 

 margin straight. Dorsal setae few and small but lateral setae dense 

 and short. Without a typical frontal suture. Anterior two-fifths of 

 plate coarsely areolate, posterior portion except for two paramedian 

 obsolete lines (appearing as sulci) smooth, the areolations more or 

 less consolidated. Prebasal plate not apparent. 



Clypeus (see also note A, p. 189): Paraclypeal sutures prominent; 

 transbuccal sutures apparently absent. Without clypeal areas, with- 

 out area of areolate consolidation except at extreme corners of labrum. 

 Setae relatively short, thick, straight, dark. Each bucca shortly 

 densely setose as shown. 



Labrum : Evenly slightly embayed; medially separated from clypeus 

 by a narrow membranous strip. Teeth all strong, dark; medial 6 

 apically blunt and flanked by more pointed teeth, the first kind 

 merging almost imperceptibly into the other, the whole labral edge 

 with 17-18 teeth. 



Mandible : Dentate lamella in three distinct, well separated blocks, 

 each with well separated, pointed teeth, right 3-3-2, left 3-3-3. 

 The simple row of hyaline teeth not overlapping the dentate lamella. 



First maxillae: Telopodite distinctly bipartite, each with two or 

 three setae. Coxosternum without medial suture; with only two 

 setae; lappets vague, short, their surfaces subsquamulate, rather broad. 



Second maxillae: Medially wide, without indication of division. 

 With prominent postmaxillary sclerites completely fused ^\'ith coxo- 

 sternites. Pore opening slightly raised and sclerotized. Telopodite 

 basal article bicondylic. Claw long, pointed, spoon shaped, each edge 

 pectinate, the teeth of the ventral edge short, of dorsal edge long and 

 hyaline. 



Prehensorial prosternum: Anteriorly broadly diastemate but not 

 denticulate. With a shallow midlongitudinal sulcus very regularly 

 areolate. Each pleuroprosternal sutiu-e margined for half its length 

 by a slight ridge (an abortive chitin or sclerotic line?).
