hyaline band. Abdomen blue, beneath with white segmental margins. In the type the 1st and 2nd radials 
are to a great extent fused. Panama (Chiricjui) and Sitio (Costa Rica). 
Ps. latifascia sp. n. (60 d) resembles tessmanni, the light area of the hindwing is just as dark yellow latijascia. 
as the transverse band of the forewing, which is more slanting and broader here. Subapical spot hyaline. 
Abdomen above darkened, all the light portions of the body chamois, not white as in tessmanni. $ type from 
Iquitos (Peru) in the Tring Museum. 
7. Genus: Ossopliaela Wkr. 
Chiefly agreeing with Pseudophaloe, but the 2nd cubitus on the forewings rises here somewhat more 
distally than in the preceding genus. 
G. latipennis B.sd. (= hopfferi G. R.) (60 f). Body blackish-brown with a blue lustre. Prothorax latipennis. 
below and collar laterally ochreous-yellow. Abdomen with a white lateral line. Wings blackish-brown, forewing 
with a discal band of light yellow spots, one of which is quadrangular, in the cell, another in the cell-angle before 
the 2nd cubitus, one being prolonged towards the base between the 2nd cubitus and the axillaris. A subapical 
row of 4 spots between the 5th radial and 1st cubital. Hindwing correspondingly marked, discal band composed 
of only 2 spots, the spot before the 2nd cubitus being absent. Distally to the transverse vein 2 spots. Beneath 
as above. Pacific States of North America. —- Larva of a black ground-colour, tubercles bluish-black, with 
a broad yellow dorsal stripe, lateral yellow streaks forming a broken line, and a yellow stigmatal band. Ventrum 
pale yellow, feet black. It lives on Cynoglossum occidentale. 
G. vermiculata G. & R. (60 f) is similar to latipennis, but the wings in an oblique light show a blue vermiculata. 
lustre, the markings are lighter, whitish-yellow; on the forewing, the light spot in the cell is slantingly prolonged 
almost to its ground; the subapical spots are broader. Hindwing quite light, the costa, margin and anal margin 
as well as the veins are dark. — In continua Ediv. the distal discal spot of the forewing is prolonged, so that continua. 
it touches the subapical spots; thereby arises a light central space into which, behind the transverse vein, 
a black spot projects. -— The form discreta Stretch (= arizona French, morrisoni Drc.) has a light disCoidal spot discreta. 
occupying only half the cell, in the hindwing the transverse vein and the 1st cubitus are broadly marked black, 
so that the subapical spots are separated from the discal spots. — The valves are narrower than in the preceding 
species. North America, Pacific States and Mexico. —- Larva quite similar to that of the preceding. 
G. aequinoctialis Wkr. (60 g) differs from the two preceding by its narrower forewings. The discal aequinoctia- 
spot behind the cell is prolonged to the base; the two other discal spots as in latipennis. Hindwing like in the lis ~ 
form arizona, the black of the margin as far as the cell very broadly projecting. Wings with a more intense 
blue lustre. Lateral dots of abdomen not strigiform as in the preceding species. — The form disjuncta Edw. disjunct a. 
has in the subapical area of the forewing behind the 1st cubitus another light dot. From Mexico to Colombia 
and Venezuela. 
G. clappiana Holl. (60 g) which was not before me, has uni-coloured black hindwings, and in the discal clappiana. 
area of the forewing only a square spot (in the cell); the subapical row only contains 3 spots. Fringes of hindwing 
white. — The form ruidosensis Cocqu. has in the discal area of the forewing two more small spots behind the ruidosensis. 
cell, in the hindwing a small round spot in the cell and three subapical spots. Colorado and New Mexico. 
G. epicharis Drc. (60 h) differs from all the preceding species by the loam-coloured to wood-brown epicharis. 
ground-colour of the wings, in which the typical Gnophaela-spots are only hazily visible. Light markings hyaline 
pale yellow, a longitudinal stripe at the costa of the forewing, a rectangular spot in the cell and some indistinct 
subapical spots. Central area of hindwing light, transverse vein and the space between the 1st and 2nd cubitus 
of the ground-colour. Guatemala. 
8. Genus : osiomorpha Fldr. 
With narrower wings than the preceding genera, in the habitus similar to the Josia- species ( Dioptidae) 
from which it is distinguished by the 2nd median being nearer to the 3rd (vein 5 nearer to 4). This mark and 
the course of subcosta and the anterior edge of the cell in the hindwing are often the only means to discern 
these Pericopinae from the species of Josia. In the latter mostly the 3rd median branch of the forewing is 
besides forked with the 1st cubitus, which never occurs in Josiomorpha. As the species of Josia are very frequently 
captured, the Josiomorpha, however, very rarely, we may presume the Pericopina to copy the other. The generic 
marks are like in the preceding genera, but owing to the forewing being narrowed, one vein is wanting, the 
3rd radial. 
J. penetrata Wkr. (= longivitta Fldr.) (60 f). Body black, thoracal sides in front yellow, sides of penetrata. 
abdomen yellow; abdomen beneath white. Wings blackish-brown, forewing with a broad yellow longitudinal
