Of female: pronotum similar, but widths of pronotal folds rough- 
ly 3 : 4 : i ; bristles of posterior fold in shallow depressions. Fore- 
wing pad nearly twice as long as broad, without marginal spines, 
completely covering atrophied hindwing. Femoral spines as in male. 
Genital Segments. Of male (figs. 3-5) : eighth tergum and ster- 
num, and gt and 9s not fused at their respective pleural junctions; 
ninth tergum deeply infolded for reception of styles, the notch-like 
pocket with nearly parallel sides, glabrous within and not divided; 
a loose cluster of short spines (12-15=+=) externally on each lateral 
border of notch. Dististyles with a row of 15=+= short spines along 
apical one-third of inner margin; submedian internal tooth acute, 
not keel-like, relatively short; a membranous element lies within an 
ovate fenestra (or stylocavernula) , broadest basally, on inner sur- 
face of each dististyle just distal to the submedian tooth. Hypan- 
drium broad, strongly emarginate apically (emargination may be 
partially closed by a hyaline membrane which is lost or worn away 
in older individuals). 
Of female (figs. 6-7) : ovipositor short, from base of tergum 10 
to apices of cerci about two- thirds length of rostrum (from lower 
margin of eye to tip). Tenth tergum prolonged on each side as a 
pair of upwardly curved divergent blades bearing 4-6 strong spines 
above, tips of blades reach distal third of cerci ; cerci separated apical- 
ly ; gonapophyses strongly spined laterally in apical halves. 
Reproductive System. Of male (fig. 8) : each testis consists of 
four lobes or “sperm tubes”, each ensheathed in a rich russet-brown 
tunic, right testis slightly anterior to left, the apices of the two testes 
reaching only slightly cephalad of swollen main portion of vas de- 
ferens (that is, the “accessory gland”) ; calyx and efferent vas of 
each testis short, thick; vas deferens tapering markedly to juncture 
of accessory gland ; accessory gland with 4 lobes, externally poorly 
delimited; lateral ejaculatory ducts barely demarcated; median ejacu- 
latory duct strong, very muscular, U-shaped; fleshy aedeagus trilobed 
when everted. Spermatozoan (fig. 8) 87-96 fi long: head 22-26 fi 
long; tail with an “undulatory membrane”. 
Of female (fig. 9) : Six ovarioles per ovary, each ovariole with 
7-1 1 panoistic egg chambers conjoined apically to ovarian ligament 
which unites with that of other ovary; ovariolar pedicels irregularly 
conjoined to common ducts which merge to form a calyx; lateral 
oviducts short; common oviduct nearly as long as an ovary; sperma- 
theca reniform, enclosing 24 sperm receptacles, 12 per side; sperma- 
thecal duct very short (less than short axis of spermatheca) arising
