180 PROCEEDINGS OF THE NATIONAL MUSEUM vol. iii 



Clypeus (see also notes A and H, pp. 189, 193): As a whole swollen 

 ventrally; much broader than long; paraclypeal sutures present but 

 extremely vague, detected with difficulty; transbuccal sutures appar- 

 ently absent. Without clypeal areas. Anterior to labral position a 

 broad arc of more strongly sclerotized and deeply colored areolation, 

 the remainder of the clypeus anterior to arc very weakly areolate; 

 the part posterior to and enclosed by the arc membranous, not areo- 

 late. With two postantennal setae and two more setae just posterior 

 to these; without posterior geminate setae. 



Labrum: Centrally membranous, with a fringe of minute hahlike 

 structures; each side of the labrum with one or two weak, poorly 

 developed obscure teeth. 



Mandible: Dentate lamella undivided, teeth blunt, well-separated, 

 eight in number. With about 13 simple, hyaline teeth, their row 

 overlapping two-thirds of the dentate lamella. 



First maxillae: Telopodite distinctly bipartite, with one seta, 

 without lappets, Coxosternum without medial suture or indication 

 of division; coarsely areolate; \vithout lappets. 



Second maxillae (see also notes B and F, pp. 189, 193): Isthmus very 

 broad, without suture or indication of division; areolation weak but 

 uniform. Each coxosternite laterally membranous; entirely without 

 postmaxillary sclerites; each pore opening somewhat thickened; ynth. 

 short laterally disposed setae and short sensory pegs medially. 

 Telopodite basally bicondjdic; apical claw spoon shaped, pointed, 

 pectinate on each edge. 



Prehensorial presternum: Laterally broadly bordered by the 

 swollen pleura. With prominent subcondylic sclerotic lines. With- 

 out sutm*es or apparent sulci; very sparsely setose. 



Prehensorial telopodite (see also note C, p. 190): No article with a 

 denticle. Ungula thin, acuminate, dilute in color, inner edge smooth. 

 Poison calyx with a cluster of digitiform sclerotic appendages. Poison 

 gland very long, extending into the prehensorial segment. 



Tergites: Basal plate not covered by the cephalic, without sutures 

 or sulci. Tergites 2 through the penultimate each very shallowly 

 Ijisulcate. Setae relatively robust and dark. wSurface coareely areo- 

 late. 



Stemites: Posteriorly without a broad triangular extension; on 

 about the anterior third of the body each is slightly indented anteri- 

 orly. Setae long, robust, dark. Approximately the first 15 each 

 with a short midlon^tudinal depression. Pore fields on a circular, 

 raised prominence, each with 4 long setae on the more anterior ster- 

 nites, decreasing to 2 setae on the rear stemites ; pore fields present on 

 sternites 2 through 55, the last 4 pedal stemites without pore fields 

 or discernible pores.
