occipital margin very slightly and broadly cmarginatc; sutures distinctly 
but shallowly marked; proximal antennal joint conico-cylindrical, greatly 
elongate, one and one-half times as long as greatest length of (>y(>; s('cond 
joint minute; third joint not ejuite half length of hrst; remainder missing. 
Pronotum with length subetiual to width, latter less than that of head; 
cejdialic margin slightly oblifiue-truncate laterad, latero-ce])hahc angles 
narrowly rounded, lateral margins faintly arcuate, faintly converging caudad, 
broadly roumling into the caudal margin, which is wodl arcuate with tlie 
faintest possible median angle; disk of ])rozona considcuably elevat(‘(l, wit h a dis- 
tinct medio-longitudinal sulcus, laterad of which is placed on each side a 
single impressed jnmeture; metazona dei)ressed, with a slight but distinct 
median carina, lateral portions considerably reflexed dorsad. 
Tegmina twice as long as i)ronotum, broad, their combineil width almost 
twice that of i)ronotum; latero-cephalic angles very well rounded, when viewed 
from dorsum the lateral margins are seen to be slightly converging caudad; 
tegmina carinate throughout their length; caudal margin slightly oblicpie, 
weakly concave. \\ ings with ex])Osed portion slightly shorter than length 
of pronotum, arcuate laterad, their ai)ices squarely truncate. 
.\bdomen subfusiform in outline; third and fourth segments bearing dis- 
tinct lateral plicae, those of fourth segment the larger; laterad the dorsal 
segments have their caudal margins weakly angtdate produce(l caudad, 
these non-carinate. Penultimate dorsal abdominal segment subrectangulate. 
transverse, greatest length contained one and oiu'-halt times in its greatest 
width, lateral margins slightly conv('rging caudad; surface ot segment with 
a faint median sulcus succeeded caudad by a small nu'ilian pit near t he caudal 
margin, latter very slightly but broadly arcuatc' between the bases ol the 
forceps; lateral angles of penult imat (> (lorsal abdominal s('gmeid well recui\c(l 
beneath the forcc'ps, with two spiiu's of which tlu' caudal (and also apiial) 
one is the largc'r. Forceps niodiuatelj' elongate*, enclosing an ('longate' |•^li■ 
foim area, the arms distinctly but not greatly depressed; base on iideunal 
siile with a large lelunt shoulder-like projection, tlu'iice moderatelv aicuate 
and converging to the consielerably recurved and talciiorm tijes, no teeth 
prc'sent but internal margin crenulate' for almost its entire l('ngth, tlu* pu- 
apical angle found in many Ancistrogastrme forms being rei-resented by an 
obtuse angle. Penultimate ventral abdonunal segment broadly ()btusc- 
angulate emarginate, with lateral angles produced iido short ac'ute i)ioje( tion>, 
lateral margins of the segment converging caudad, the whole i)lat(‘ dei-idedly 
transverse. Limbs elongate and very slender; caiulal nudatarsus slightly 
exceeding the third tarsal joint in h'ligth.
