four times as wide as long (4.4:1), being considerably overlapped by 

 cephalic plate, at sides the length ^ the width (Plate 1, fig. 2). 



For labrum see Plate 1, fig. 4 Lappets of first maxillae large, 

 membranous. 



Antennae long to very long, all articles long excepting a few before 

 the ultimate; ultimate article clearly shorter than the two preceding 

 together (5:4); most articles clothed with a limited number of long 

 straight bristles subdefinitely arranged, the distal articles becoming 

 densely clothed with finer, shorter, straight hairs. 



Claws of prehensorial feet when closed extending much beyond 

 cephalic margin of head but not fully attaining the distal end of first 

 antennal article. The claw with a small, subcylindrical, blunt tooth 

 at base; first joint with a very low, obtuse denticule; other joints 

 and presternum unarmed. Presternum with anterior mesal margin 

 widely but only weakly sinuate; subquadrate; wider than long in 

 about ratio 20:17, considerably less than twice as long as the coxa 

 (32:21); coxopleural suture subparallel with lateral margin, curving 

 mesad a little in going caudad. Chitinous lines very weak and in- 

 distinct. Presternum and prehensorial feet both almost glabrous, 

 bearing a few long, scattered bristles (Plate 1, fig. 1). 



Anterior prescuta short, becoming long in middle and posterior 

 regions. 



Anterior spiracles moderately large, the first considerably longer 

 than the second, broadly elliptic, a few following subsimilar, but nearly 

 all circular, the ultimate ones becoming small. 



Ventral pores in a rather large circular to somewhat quadrate or 

 broadly diamond-shaped area on median caudal portion of plate; 

 in front of poriferous area a median sulcus extending toward anterior 

 margin, this crossed a little cephalad of its caudal end by a number 

 of transverse lines. 



First pairs of legs shorter and much more slender than the second; 

 anterior legs clearly more robust than the posterior pairs but of about 

 equal length; legs very sparsely hirsute. 



Last ventral plate very wide, all margins straight or the caudal a 

 little indented mesially with its lateral portions a little convex, the 

 lateral margins not strongly converging caudad. Coxopleurae mod- 

 erately enlarged; each with two pits which are usually covered or 

 mostly so by the last ventral plate. 



Anal pores concealed. 



Anal legs in the male much longer than the penult, crassate, the 

 ultimate articles less so than the proximal; no claw, there being in its
