termination of the lamellae; lamellae sinuous from above 

 and from before so that their anterior-most section is closest 

 to cephalothorax though projecting distinctly from cephalo- 

 thorax throughout most of their length, appearing smoothly 

 rounded from the side (fig. 13) and band-like with the hair 

 pore at anterior-most part and very near edge, curving 

 ventrally to abut against the anterior-most end of ventral 

 plate ; sides of cephalothorax obtusely angled antero-iaterally 

 so as to form an angular channel between it and the lamellae ; 

 pseudostigmatic organs (fig. 14 — foreshortened) medium- 

 long, not surpassing lateral edge of the pteromorphae when 

 viewed from above,, elbowed at proximal end, rigid, with 

 very slender slightly sinuous shaft, and wide, unsym- 

 metrically oval head which appears coarsely granular; 

 pseudostigmata flush and inconspicuous; tectopedia (fig. 13) 

 narrow, band-like, tapering to a point ventrally, filling in 

 space between pteromorphae and lamellae. 



Notogaster (fig. 10) medium high, gently convex, 

 smooth, anterior edge distinct, posterior edge truncate, with 

 latero-posterior edge overlapping ventral plate ; areae porosae : 

 anterior ones inconspicuous, elongate-ovate, lying along 

 (half on each side of) anterior edge of notogaster (fig. 13), 

 appearing contiguous to posterior thoracic apophyses which 

 are short, prominent and converging; adalares inconspicuous, 

 very short and blunt; posterior mesonotal circular, decidedly 

 remote from each other; posterior lateral oval, not close to 

 the previous and almost directly posteriad ; posterior mesial 

 oval, further from the posterior lateral than the posterior 

 lateral are from the posterior mesonotal, and slightly larger 

 than the posterior lateral; tracheal foramina as in figures. 

 Those about the posterior mesonotal areae porosae fairly 

 constant in relative position. 



Pteromorphae normal, gently rounded anteriorly; notch 

 in ventral margin situated rather far anteriorly ; posterior angle 

 obtuse, somewhat over a right angle; groove narrow, with an 

 inconspicuous pore anteriorly ; nervures short, not prominent^ 

 not crowded on disc, much more so along ventral edge. 



Ventral plate (fig. 12) relatively flat, anterior edge 

 gently sinuous, limited anteriorly by camerostome and 

 lamellae; leg cases not encroaching far upon ventral plate, 

 their ventral outline sinuous, formed by ventral border of 

 apodematal butts, pteromorphae far surpassing this line and 

 reaching when closed nearly to the foramina or pores which 

 diverge from base of camerostome, ventral plate therefore 

 without lateral depressions for housing the pteromorphae ; 

 genital covers small, narrowing posteriorly, each with two
