Some British Moths Described 
Triphena ianthina: the Lesser Broad ~ Bordered 
Yellow Underwing (Plate VIII, Fig. 22).—Expanse, 
1% inches. There are six different species of Yellow 
Underwings, and they are all more or less variable. 
lanthina is fairly common at sugar during July. I 
have picked up many fine specimens under electric 
standards at night. ‘They fly madly at the globes, get - 
stunned with the impact, and flutter to the ground. I 
notice they recover in a short time and make off. The 
larva may be found in the spring on Primrose and 
allied plants, such as Auriculas, etc. 
Triphena fimbria: the Broad-Bordered Yellow 
Underwing (Plate VIII., Fig. 23).—While the under- 
wing of this fine species remains very constant in 
colouring, the upper wing is just the reverse. Its 
ground colour may be light buff, olive brown, nut 
brown, dark grey, or nearly black. Comes to sugar 
in July and August. The larva feeds on Primrose 
and other low plants. Expanse of moth, 24 inches, 
Lriphena comes: the Lesser Narrow - Bordered 
Yellow Underwing (Plate VIIL, Fig. 24).—This and 
L’. orbona are the only two members of the family likely 
to be confused. Ordona can be distinguished by a black 
dash near the tip of the fore-wing, just at the costal end 
of the submarginal line. This mark is not present in 
Comes. Orbona is scarce; Comes is very abundant, 
from Caithness to Cornwall. Its range of variation is 
endless. Generally, northern specimens are very dark, 
with the stigmata outlined in white. Larva represented 
on Plate VII, Fig. 6; food and conditions same as
