6 PROCEEDINGS OF THE NATIONAL MUSEUM vol. in 



longitudinally with two distinct paramedian sutures; each with a pair 

 of broad very shallow longitudinal submarginal troughs or sulci ectal 

 to the aforementioned paramedian sutures, the sulci delineating very 

 weakly defined atypical tergital margins on about 3 or 4 through 22. 



Sternites 1-22 : Each whitish and translucent, the underlying mus- 

 culature visible; setae extremely sparse and minute. Each longer 

 than wide. Each with a shallow midlongitudinal and rather broad 

 sulcus, these best seen on 1 through 20 or so, thereafter evanescent, 

 barely discernible on 20 and 21; cross-sulci apparently absent; sub- 

 marginal sulci absent. 



Spiracles: Present on pedal segments 3, 5, 8, 10, 12, 14, 16, 18, 20, 

 and 22 (see note 2, p. 13). Legs 1-22 whitish to dilute yellowish- 

 white; setae tiny and sparse except on prefemora and femora, which 

 have a few more robust and deeply colored setae. Legs 1-21 each 

 thin and relativel}'- very long (10th leg not including trochanter and 

 pretarsus, 6.17 mm.; 1st tarsus (1.17 mm.)+2d tarsus (0.57 mm.)> 

 tibia (1.57 mm.)> prefemur (1.53 mm.)>femur (1.33 mm.)); a pale 

 suture incomplete only dorsally indistinctly dividing each tarsus into 

 a longer very slightly thicker proximo tarsus and a shorter very slightly 

 thinner distotarsus; dorsal condyles absent on 1-21; each pretarsus 

 with 2 very long thin accessory claws (actually spurs ankjdosed to base 

 of pretarsus) . Legpair 22: Tarsus completely divided, with a promi- 

 nent pigmented dorsal condyle; slightly longer than preceding legs, 

 otherwise not differing significantly. Prectrotaxy: VTaM=l-21, 

 VTiM=l-22, DTiA=l-21; pretarsal accessories =1-22. 



Ultimate pedal segment and legs: Tergite yellowish, opaque, with 

 about 20 scattered setae; without sutures or sulci; slightly longer than 

 wide, posterior margin evenly bowed outward, the apex round and 

 broad; side abruptly reflected upward on each side to form a flange 

 with the contingent upper coxopleural margin. Coxopleuron yellow- 

 ish-white, opaque; with a few stout setae; porigerous area without 

 setae reaching anterior margin but separated from dorsal margin by a 

 narrow strip, posteriorly sloping ventrally to posterior and ventral 

 margins, pores small, numbering at least 100 on each side; ventro- 

 lateral margin not reflected into a flange, not submarginally sulcate; 

 each coxopleural spinous process very thin, almost ensiform, between 

 }i and % as long as posterior margin is high, tipped with a black point 

 and 2 delicate setae, its shaft ventrally with 2 stout setae; the ventral 

 edges of the 2 coxopleura contiguous for nearly their entire lengths. 

 Ultimate legs: Right (left abnormal), excluding pretarsus, 6.0 mm. long 

 (i.e., prefemur+ trochanter =1.80 mm., femur=1.50 mm., tibia=1.27 

 mm., 1st tarsus=0.60 mm., 2d tarsus=0.83 mm.); yellow and opaque; 

 trochanter nearly completely amalgamated with prefemur, the latter 

 very slightly flattened dorsally, the remaining articles dorsally
