36 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 1 28 



subquadrate, or rhomboidal pits which are only one-third to one-half 

 the diameter of the ovoid scrobiculi on lateral thirds of scutum. In 

 G. decora (fig. 182) the medial pits are subequai in size to the lateral 

 ones. In the new species the PLs are in a line with SB, instead of 

 being well anterior to SB as in decora. 



Description of larva. — Body: Ovate, about 363 x 205 microns in 

 rather engorged holotype. Eyes inapparent in specimens extant. Gna- 

 thosoma: Chelicerae about five times as long as broad at base; with 

 typical tricuspid cap, Cheliceral bases and palpal coxae and femora 

 heavily punctate. Palpal formula B/B/bNb. Palpal claw 3-pronged 

 but usually appearing 2-pronged ; middle prong slightly longer than 

 others. Scutum: Long, broad, and evenly tongue-shaped; 266 x 166 

 microns at maxima in holotype. Anterior margin almost straight. 

 "Shoulders" at anterolateral angles undeveloped. Lateral margin 

 shallowly convex except between AL-PL, where it is slightly concave. 

 Posterior margin evenly rounded. Uniformly micropunctate except 

 for elliptical region around SB and for scrobiculi. Highly ornamented 

 by virtue of the scrobiculi which extend over entire scutum. These 

 scrobiculi of two types — medial and lateral. Medial pits forming a 

 broad "central core" (fig. 102, C.C.) along longitudinal midline of 

 scutum and consisting usually of small ellipses, or trigonal or sub- 

 quadrate scrobiculi about twice the diameter of pores of dorsal setae. 

 Lateral thirds of scutum covered with scrobiculi two to three times 

 the diameter of those in median core ; scrobiculi dorsally subovate 

 (as in fig. 102, right side), but at a more ventral depth of focus, 

 scrobiculi are definitely hexagonal (as depicted in fig. 102, left side) 

 and are even set in a mosaic pattern. Pits between and anterior to SB 

 generally resembling those of central group. AL setae fairly stout; 

 sparsely plumed. Bases of PLs just below those of sensillae. PL setae 

 resembling ALs but almost twice as long. The two pairs of scutal 

 setae usurped from dorsal rows ; marginal ; resembling ALs. First 

 pair of usurped setae (PPL-i) inserted slightly above level of mid- 

 point of coxa III ; PPL-2 inserted at apical fifth. Sensillae bases 

 surrounded by a well-delineated, ovate, oblique, unadorned area. Sen- 

 sillae missing in specimens extant. PPW-i is 132 (±10) ; PPW-2, 

 126 (±9); PPP-i, 165 (±15); PPP-2, 36 (±5). Body setae:
