36 Mr. R. Shelford on some 
different from the other two species, and may well be selected 
as the type of the genus, which can be distinguished by the 
following characters :— 
Broad, convex insects; the tegmina not projecting much 
beyond the tip of the abdomen, their venation sometimes 
obsolete in the anal and discoidal fields. Wings with an 
apical triangle, the ulnar vein ramose. [emora generally 
strongly armed. Supra-anal lamina variable, but usually 
produced. 
Type of the genus P. insularis, Sauss. 
The other species of the genus are P. bipunctata, W1\k., 
P. adimonialis, Wik. (=Lupparia adimonialis), possibly 
P. latipennis, Br. (= Phyllodromia latipennis), and the new 
species described above. Of the species previously included 
in the genus, P. pallidula, Bol., and P. veltzkowiana, Sauss. 
& Zehnt., have the supra-anal lamina produced, the abdomen 
is missing in P, Luneli, Sauss., and in P. intermedia, Sauss. & 
Zehut.; it is probable that the shape of this tergite is as 
variable as in the genus Phyllodromia, and too much reliance 
should not be placed on its transverse form in P. subpectinata, 
Sauss. & Zehnt., and P. antiguensis, Sauss. & Zehnt. In all 
these species the armature of the femora is most variable. 
They cannot be placed in the genus Theganopteryx on account 
of the ramose character of the vena ulnaris alarum (cf. Trans. 
Ent. Soc. p. 232, 1906), but the presence of a triangular apical 
area in the wings does not forbid their entry in the genus 
Phyllodromia, seeing that this character does occur in several 
well-marked and well-recognized species of that genus. 
P. punctulata, Sauss. & Zehut., must be referred to the genus 
Theganoptery. 
Subfam. Nrorreorin 2. 
Nyctibora bicolor, sp. n. 
?. Head entirely black, with a scanty erect pubescence 
on the front; ocelli minute, testaceous ; antenne incrassated, 
black, apical joints rufescent, densely pubescent. Pronotum 
transversely elliptical, anterior border not nearly covering 
vertex of head ; posterior border more arcuate than anterior, 
covering the scutellum; disk with two converging impressions, 
flavo-testaceous, with a shield-shaped black mark on the disk, 
posterior margin with a fine black line. Tegmina coriaceous, 
serlo-punctate and reticulate between the raised veins, not 
pubescent ; the basal three fifths flavo-testaceous, the apical 
two fifths dark castaneous; radial vein black throughout its
