shorter, more remote, posterior nearly round, more approximate 

 than mesonotical, pseudofissurae short, length of mesonotical 

 areae porosae distant from these bodies; pseudoforamina as in 

 PL 19, fig. b and c. Pale spot at anterior end seems to be due to 

 lack of pigment as also to local transluscency. Overlapping sides 

 of notogaster unusually broad (deep) , with rim strongly contracted 

 (PI. 19, fig. 6), so that it may be detracted until below (covering 

 insertion of) postanal bristles. Pteromorphae more than semi- 

 circular, nearly as broad as long, so as to extend far below leg 

 insertions, in fact so far down on sides as to reach to within the 

 breadth of a genital cover from genital aperture. Anterior edge 

 strongly undulate (PI. 19, fig. d-f) but middle of anterior edge 

 extending well beyond (anteriad of) median edge, thus broadly 

 overlapping upper half of tectopedia II. Posterior edge extend- 

 ing far enough back as to be attached on sides of notogaster and 

 not (as in Scheloribates) on lower rim (PI. 19, fig. 6). Surface 

 faintly veined (PI. 19, fig. b, c, /), with a pseudoforamen (or 

 bristle insertion) near antero-dorsal corner; pseudofissurae near 

 center, transverse, short (PL 19, fig. 6). 



Ventral plate (PL 19, fig. a) with anterior half strongly con- 

 stricted, quite flat (PL 19 fig. 6), anal aperture remote from 

 posterior edge, this area strongly transversely depressed (!) (PL 

 19, fig. 6); anal aperture broader than long, sides gently convex, 

 only slightly tapering, posterior corners somewhat angular, no 

 anterior emargination ! covers crenelate along median edge, an- 

 terior pair of cover bristles fairly long, inserted close to anterior 

 rim, posterior pair slightly shorter, closer to median than to 

 posterior edge; postanal bristles rather short, median pair more 

 remote than posterior cover bristles, more approximate than 

 center of covers; outer pair more remote than center of covers, 

 fairly close to median pair, further from aperture than median 

 pair; paranal bristles at center of covers, more distant from 

 pseudofissurae than length of latter, sometimes opposite an- 

 terior sometimes posterior end of pseudofissurae, sometimes dis- 

 similar in the one individual (as in PL 19, fig. a); pseudofissurae 

 short, on outer rim of aperture; paramesial bristles fairly long, 

 inserted more remotely than diameter of anal aperture, more 

 distant from genital aperture than diameter of one of its covers. 

 Genital aperture broader than long, sides nearly straight, an-
