FULGOROIDEA OF TRINIDAD—FENNAH 465 
Subfamily PHENACINAE 
Genus PHENAX Germar 
Phenagz GERMAR, Rey. Ent. Silbermann, vol. 1, p. 175, 1838. (Genotype, Fulgora 
variegata Olivier.) 
Vertex broader than long ( 4 to 1), quadrate, impressed on each side 
of middle, separated from frons by a single slightly curved carina, 
lateral margins elevated, basal margin shallowly excavate; frons 
broader at widest part than long, margins expanding sinuately and 
gradually to below level of antennae, then abruptly dilated and curved 
posteriorly to form a strong flange below antennae, the width of the 
frons at this level being twice its width at base, median carina present 
on basal half only, lateral carinae joined basally at middle at level of 
eyes, curving outward, downward, and then slightly inward to level 
of apex of median carina, then strongly diverging to suture, a short 
curved carina basally, directed distally, terminating at level of middle 
of eyes; clypeus almost equilaterally triangular, lateral margins curved 
sharply inward near suture, elevated middle portion of clypeus tumid, 
median carina present; antennae with first segment short, cylindrical, 
second segment globose, pitted with sensoria. Pronotum much broader 
than head, anterior margin of disk straight, posterior margin slightly 
convex, median carina present, lateral carinae diverging in a straight 
line to tegulae, lateral margins carinate between eye and lower margin 
of tegula on each side, ventrolateral margin of pronotum bent forward, 
forming a furrow; mesonotum more than twice as wide as long, devoid 
of median carina except at apex, lateral carinae obscure. Legs long, 
femora and tibiae rectangular, margins minutely setose, posttibiae with 
five or six spines. Tegmina expanding for two-thirds of length from 
base, apical margin very oblique, almost straight, coriaceous or papyra- 
ceous, Sc strong to middle, R forking at basal third, M and Cu, forking 
about basal quarter, transverse veins numerous beyond nodal line, 
regular, crescentically curved, occurring between all the supernumer- 
_ ary longitudinal veins. Wings densely reticulate.

Female: Length, 25 mm.; tegmen, 54 mm. 
Frons about 3.5 mm. wide at base, 7.0 mm. wide at apex. Protibiae 
and mesotibiae one-fifth longer than femora. 
Head yellowish brown, a piceous spot on vertex on each side of middle 
line, a piceous area between carinae on basal half of frons, distally two
