segment brownish fuscous; segmental measurements; I, 8; II, 8; 
IlI, 84; IV, 28. Labium brownish, extending onto metasternum; 
uniseriate, nearly parallel on mesosternum, subcordate with ends not 
quite meeting on metasternum. Orifice of metathoracic scent glands 
with an upright channel on each metapleuron. Legs rather slender, 
testaceous with a brownish tinge, inconspicuously pubescent. Length 
4.30 mm., width (across elytral band) 1.75 mm. 
Pronotum moderately convex, punctate, tricarinate, mostly con- 
cealed by the enormous, semiglobose, reflexed paranota, which cover 
all but apex of head, and by the median and triangular process of 
pronotum; median carina considerably elevated, areolate; lateral 
carinae strongly elevated on pronotum, semiglobose, almost as folli- 
aceous as paranota, strongly concave close to the outer margin of 
pronotum under the paranota, thus not clearly visible from dorsal 
aspect; paranota exceedingly large, semiglobose, erect, with sides 
meeting in front, with outer margins forming an angulate opening pos- 
teriorly so as to expose discal surface of pronotum; collar truncate in 
front, sharply elevated at middle so as to form a small tectiform 
hood. 
Elytra wider and longer than abdomen, testaceous with premedian 
crossband, apical part and many veinlets in discoidal and sutural 
areas brown or brownish fuscous; costal area moderately wide, 
biseriate, areolae (except in band and darkened apex) hyaline; sub- 
costal area narrower than costal area, upright, biseriate; discoidal 
area very large, extending considerably beyond middle of elytra, with 
outer boundary vein slightly arcuate, acutely angulate at base and 
apex, widest at middle, there eight or nine areolae deep; sutural 
area large, on same horizontal plane as discoidal area, the areolae 
becoming a little larger posteriorly. 
Typr: Holotype (female), Tonkin, Vietnam, August 1930, USNM 
65127. 
Remarks: The holotype of Z. petrosa is illustrated in figure 18. 
This species is closely related to Zeratingis dissita, new species, by 
similar coloration and the extremely large, inflated, upright paranota. 
Distinguishing characteristics are given in the remarks immediately 
below under Z. dissita. 
Zeiratingis dissita, new species 
Description: Large, oblong, with enormous paranota. Brownish 
with costal areas (except premedian and apical bands brown, including 
cells) and apices of discoidal areas testaceous; body beneath dark 
brown; bucculae and antennae brownish testaceous, legs brownish; 
pronotal carinae brownish testaceous. Length 4.75 mm., width of 
elytra 2.10 mm., width of paranota 2.40 mm., height of paranotum 
2.10 mm.
