margin deeply emarginate ; its lappets not squamiilate, nearly trans- 

 parent, extremely broad basally. 



Second maxillae (see also notes B and F, pp. 189, 193) : Wealdy areo- 

 late, nearly membranous, the two sides very broadly joined. Areo- 

 late postmaxUlary sclerites present. Each pore opening surrounded 

 by a weak sclerotic rim. Without typical setae, but with setifomi 

 sensory points as shown. Telopodite basal article bicondylic; claw 

 pointed, spoon shaped, the ventral edge pectinate, the processes very 

 long and delicate, nearly transparent; dorsal edge not discernibly 

 pectinate, apparentlj^ smooth. 



Prehensorial prosternum: Broad and short, margined by bulging 

 pleura. Anteromedially weakly emarginate. Pleuroposternal sutures 

 distinct, otherwise without sutures or apparent sulci. 



Prehensorial telopodites (see also note C, p. 190) : When closed, not 

 attaining anterior head margin. No article with a denticle. Femuroid 

 and tibioid together bulging toward body midline. Ungula broad 

 and robust; ^vith two distinct edges and a deep groove separating 

 them, the ventral edge dissected to form coarse teeth, the teeth 

 approximately subquadrate, short, five or six in number, limited to 

 the basal two-thirds of blade. Poison calyx spherical, composed of 

 bunched digitiform sclerotic processes. Poison calyx long and thin, 

 terminating in the prehensorial segment at nearly one-half the distance 

 to its posterior border. 



Tergites: Apparently not sulcate; sparsely setose. 



Sternites: Coarsely, prominently areolate, sparsely setose. Pos- 

 terior margins, especially of more anterior sternites, extending back- 

 ward in a broad low triangle; the first 10-15, at least, with a shallow 

 midlongitudinal sulcus. Two pore fields on each sternite from and 

 including the second through the penultimate, each field linear and 

 diverging angularly from its bilateral counterpart, none raised, each 

 consisting of a few small pores (e.g., 2nd =5 + 5, 4th =8 -{-8, 34th = 

 5+4). 



Ultimate pedal segment: Pretergite bilaterally suturate, i.e., de- 

 lineated from its pleurites on each side by a distinct longitudinal 

 suture. Tergite much broader than long, posterior margin widely 

 bowed backward. Presternite extensive, indistinctly sulcate medially. 

 Sternite very wide and short, sides coverging posteriorly, Coxo- 

 pleuron not gi*eatly swollen, not larger than certain of the leg articles, 

 its axis not directed posteriorly, rather posterolaterally, forming an 

 acute angle with the long bod}^ axis; sparsel}'' setose; without pores 

 or pits, and with no discernible glands. Leg with five articles distal 

 to the coxopleuron, the tarsus consisting of one article, the pretarsus 

 represented by a minute acicular bristle (not visible at powers under
