ZOOLOGY OP FERNANDO NORONHA. 
527 
Ochraceous, head-plate slightly darker. 
Number of pairs of legs 73 (in the female). 
Antennae hirsute, the distal end more so than the proximal. 
Segments of the proximal half cylindrical, those of the distal half 
narrowed proximally ; apical segment as long as the two pre- 
ceding segments. 
Head-plate with straight anterior margin, rounded lateral 
margins, and concave posterior margin ; sparsely clothed with 
hairs, and almost destitute of punctures. 
Frontal lamina coalesced with rest of head-plate. 
Basal lamina about twice as wide as long, with abruptly con- 
verging lateral margins and concave anterior margin. Tbe pre- 
basal lamina visible in the space left between the concave 
posterior border of the head-plate and the concave anterior 
border of the basal lamina. 
Maxillary sternite wider than long; its anterior margin slightly 
excavated, but scarcely bidentate. 
Maxillary feet largely visible from above, and projecting 
slightly in front of the head-plate ; the segments on the inner 
side furnished with hairs but not armed with teeth. 
Dorsal plates conspicuously, bisulcated. 
Ventral pores occupying a circular area in the posterior half 
of the sternites. 
Legs sparsely clothed with longish hairs. 
The anal tergite wide, but not covering the pleurae ; with 
rounded postero-lateral angles, staight posterior margin, and 
lateral margins slightly converging behind. 
Anal pleurae smooth, not furnished with punctures. 
Anal sternite very wide at the base, gently converging lateral 
borders, rounded posterior angles and straight posterior margin. 
Anal pores conspicuous. Anal legs broken. 
A single female specimen, found under a stone in the Sapate. 
This species appears to be closely allied to G. occidentalism 
Meinert (Proc. Amer. Phil. Soc. xxiii. p. 220), from San 
Francisco ; but differs in the absence of teeth from the segments 
of the maxillary feet, and in the absence of pores from the anal 
pleurae.
