on the soil. Nodaria extremalis, Guen., has similar blit shorter palpi, 
and a narrower forewing. Dichromia erosia, Cram., lias porrect palpi; 
the hindwing is orange, the forewing grey with a large black triangular 
patch. Rhynchina has porrect palpi, the forewing narrow and acute at 
the apex. R. abducalis, Wlk., is the most common, the forewing with 
a long dark patch bounded below by an oblique light line running from 
the apex. 
Hypena is a large genus of seventy species, the palpi porrect and of 
varied length. H. lividalis, Hubn.; H. iconicalis, Wlk.; H. abyssinialis, 
Guen. : H. indicatalis, Wlk., are the most widespread species; the identi¬ 
fication of these and the other forms is possible only if a long series of 
specimens is available or if they can be compared with accurately identi¬ 
fied specimens. A species was reared by de Niceville on indigo in Cham- 
paran (I. M. Notes, V, p. 163). 
Hyblceincc—Hyblcea puera, Cram.; and H. constellata, Guen., are 
common where teak (Tectona grandis) grows, their larvae defoliating 
this tree ; the life-history of the former is fully described by R. S. Hole. 
(Journ. Bo. Nat. Hist. Soc., Vol. XV, p. 679.) 
Collecting.-— Most noctuids are nocturnal and many can be 
captured at light, some come to sugar (a mixture of treacle or syrup 
and spirit) and some to ripe fruit. Numbers can be caught in thick 
grass, on tree bark and in similar situations by day. There is a large 
field for rearing as only a small percentage are known from the larva 
and they are, as a rule, easily found and reared. Large numbers of 
species are as yet undescribed probably and large collections can be 
made anywhere in India. 
Pterothysanim;. 
Frenulum absent. Hindwing with vein 8 approximated to 7 at 
middle of cell . lc. absent. Forewing with vein 5 nearer 4 than 6. 
This family consists of a single genus (Pterothysanus) of moths, 
found in Assam and Burmah with five doubtful species. They are large 
diurnal insects, with small upturned palpi, simple antennae, and long 
hair fringes to the hindwings. The colouring is vivid black with white 
and pink blotches on the wings. The larva is unknown and the moths are 
not common anywhere. None are found in the plains.
