170 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 113 
Typz: Holotype (female), Davao, Mindanao, Philippines, C. F. 
Baker, USNM 65124. 
Remarks: The holotype of Z. scitula is illustrated in figure 15. 
This is one of the prettiest, most strikingly colored lacebugs of the 
Philippines. 
Banahaona, new genus 
Description: Elongate, slender, nearly parallel sided. 
Head short, little extended in front of eyes, armed with five spines, 
eyes behind touching foremargin of pronotum; bucculae long, wide, 
areolate, with ends contiguous in front, not projecting beyond the 
tip of clypeus. Antennae rather short; segment I shortest, stouter 
than II; segment II a little longer than I; segment III longest, moder- 
ately slender; segment IV longer than II, fusiform. Labium fairly 
long, extending between middle coxae; laminae low on prosternum, 
higher and mostly uniseriate on mesosternum, still higher and largely 
biseriate on metasternum, open behind but with inner surfaces resting 
flatly against each other apically. Orifice and sulcus of metathoracic 
scent glands not visible. Hypocostal lamina uniseriate. 
Pronotum moderately convex, punctate, tricarinate, largely con- 
cealed by the completely reflexed paranota; only the median carina, 
posterior process, anterior part of collar, and small hood visible from 
dorsal aspect; median carina long, lateral carinae converging anteriorly 
on posterior process, then running against median carina beneath the 
reflexed paranota almost to calli, slightly divergent just behind calli; 
paranota very large, with outer margins touching median carina, each 
paranotum with two prominent well formed longitudinal carinae, the 
long median carina extending the entire length of paranotum, the 
other carina near humeral angle much shorter; hood small, triangular 
in outline, not produced in front. 
Elytra long, narrow, not wider than pronotum at humeral angles, 
longer than abdomen, with sutural areas overlapping so as to rest 
with apices jointly rounded behind, divided into the usual areas; 
costal area narrow; subcostal area also narrow, subvertical; discoidal 
area large, extending beyond middle of elytra, on same horizontal 
plane as that of sutural area. 
Type specius: Banahaona exalla, new species. 
Remarks: This genus can be distinguished at once from all other 
genera of the subfamily Tinginae by the prominent median longi- 
tudinal carinae of the paranota. These carinae are not related to the 
lateral carinae of the pronotum, although at first glance they appear 
to be true pronotal carinae. The paranotal and pronotal carinae are 
quite distinct from one another. The median longitudinal carina of 
each paranotum is long, straight, and prominent and extends from the
