straight or slightly convex; anterior and posterior margins strsdght, 

 parallel. Segment 3 triangular, outer margin approximately tvfice as 

 long as inner margin. Palpi vent rally with segments 2 and 3 of al- 

 most equal length, segment 3 bearing a small triangular retrograde 

 spur extending just beyond the apex of segment 2; segment U small, 

 inserted in pit of segment 3; segment 1 forming a slight pedicle 

 for palpi and bearing at its inner basal margin a slight knob with 

 at least one bristle. Hypostome twice sis long as \rf.de, apical 

 margin broadly rounded and notched medially j a dense corona present; 

 dentition 5/5, with nine to eleven denticles in each file, files of 

 equal length. 



Scutm; Outline narrowly elongate with lateral margins par- 

 allel, posterior margin bluntly rounded; lateral margins widening 

 slightly over scapulae; anterior emargination deep. Posteromedian 

 and paramedian grooves shallow, narrow, short, and indistinct, 

 situated at level of spiracular plates. Cervical grooves shallow 

 but distinctly divergent to lateral margin posterior of eyes. 

 Eiyes on latercG. margin at level of coxa 2j small but distinct, 

 rounded and slightly raised. Surface of scutum smooth and shiny, 

 with a narrow median field of few scattered pxmctations extending 

 the fiill length of the scut\m; a single row of twelve hairs along 

 posterior margin and a few hairs among posterior grooves; area 

 between cervical grooves and lateral margins punctate and bearing 

 scattered fine, long, white hairs; a row of hairs also situated 

 on anterior margin between cervical grooves. Integument bulging 

 around scutum from level of eyes posteriorly; furnished with reg- 

 ularly scattered, dense, long, white, conspicuous hairs bordering 

 scutum to level of spiracular plates; thence these hairs more 

 confined to narrow lateral surface of integument around posterior 

 margin of scutimi, few or no hairs on dorsal svtrface in this area. 



Spiracular plate subcircular, with one and a half rows of 

 large gotlets surrounding aperture. Genital apertvire sitviated 

 at midlevel of coxa II, anterior and posterior margins paredlel, 

 lateral margins slightly converging posteriorly. Genital grooves 

 extending from genital aperture to level of anvis, slightly diver- 

 gent. AdansJ. shields commencing at anterior level of coxa IV and 

 extending beyond level of anus almost to posterior margin of body 

 (depending on degree of integumental stretching due to feeding), 

 narrowly elongate, slightly expanded just anterior of anxis.
