Orochion gen. nov. (fig. 825) 
oqo ; = mountain, yjo'iv = snow 
Head smooth, vertex with a rough erect tuft between antennae. Ocellus 
absent. Proboscis short. Antenna 5 /„, filiform, scape strongly dilated with 
scales, so as to form a short, broad eyecap. Labial palpus moderate, 
porrect or drooping, median segment moderately thickened towards apex

with scales somewhat roughish above and beneath, terminal segment 1, 
moderately thickened, smooth, subobtuse. Maxillary palpus vestigial. 
Posterior tibia with bristly projecting scales above, forming a small tuft 
at apex, first and second basal segments of posterior tarsus with a small 
whorl of blackish bristles. Fore wing without tufts of raised scales, lance- 
olate, apex narrowly produced, lb long-furcate, 2 from angle, 4 vestigial 
(basal stump perceptible), 5 approximated to 6 at abse, convergent poste- 
riorly, 6 to termen, 7 out of 6, to apex, 8 absent, 9 approximated, 1 1 from 
slightly before middle. Hind wing 1 / 3 , linear-lanceolate, cilia 7 ; one strong 
anal vein furcate at base; 2 long, close to margin, 4 absent, cell open 
between if and 5, 5 and 6 stalked, stalk apparently out of 7, 6 to termen, 
7 running from base to apex, 8 short. 
Genotype Orochion undulosa spec, nov., female. 
Belongs to the Bedellia group, and characteristic by a strong reduction 
of the veins in the hind wing, contrasted by only a moderate reduction of 
the veins in the fore wing. The neuration in the hind wing reminds of that 
in the Douglasiidae, but there is no actual relationship with that family.
