290 INSECTA, 
ZYGIENA. 
The Zygene are not found in the western continent. Their an- 
tenn are simple in both sexes, and terminate abruptly in a fusiform 
club, or one resembling a ram’s horn; their inferior palpi extend be- 
yond the clypeus, and are pointed at the extr emity. 
Z. filipendule ; Sphing filipendwle, L.; Rees., Insect., I, 
Class II, Pap. Noct., lvii. Black or bluish- ereen ; six red spots 
on the superior wings ; the inferior ones red, with their poste- 
rior margin the colour of the body. 
The caterpillar is lemon-yellow, slightly pilose, with five 
series of black spots along the body. It spins a straw-coloured, 
glossy, elongated, and fusiform cocoon on the stems of plants. 
Its surface is wrinkled or plaited. The perfect Insect appears 
in July * 
Syntomis, [/kq., 
Only differing from Zygzena in the antennze, which are not so thick, 
and insensibly fusiform and slender. The inferior ‘palpi are shorter 
and obtuse f. 
Arycuia, Hoff., Iiliq., 
Where the antennze are simple (in the females), or bipectinate (in 
the males), according to the sex; the inferior palpi are densely pilose 
and extend considerably beyond the clypeus. ‘The wings are short, 
and the extremity of the posterior tibiz is furnished with very 
strong spines {. The 
Procris, Fab., 
Approaches Atychia in the antennz; but the inferior palpi are 
shorter and not hairy. The wings are long, and the spurs of the 
posterior tibize are small. 
P. statices; Sphina statices, L.; P. turquoise, De Geer, Ine 
sect., II, p. 255, iii, 8—10. Body glossy green, as if gilt; in- 
ferior wings brown; antennz of the male with two series of 
black setze, those of the females somewhat serrated. 
In the other Lepidoptera of this division, the antennz of both 
sexes are bipectinated or furnished with a double row of elongated 
teeth. ‘Those which have a distinct proboscis form the subgenus 
Guavucopris of Fabricius §, and those in which that organ is wanting, 
or is not distinct, that of AGLAops |}.

Near the Syntomides comes the genus PsicoTHor, established by M. Bois-Duval, 
in his Europ. Lepid. Index Méthod., and, according to him, distinct from all other 
Zygenides in its moniliform antenne and immaculate wings. It comprises but a 
single species, P. Duvancelii, found in Bengal, by M. Diard and the late M. Du- 
vauncel.
