ZTGiENA. 



The Zygsenae are not found in the western continent. Their an- 

 tennae 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 extremity. 



Z. filipendulcs ; '''Jpldnx filipendula; , L. ; Roes., Insect., I, 

 Class II, Pap. Noct., Ivii. Black or bluish-green ; 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, Illig., 



Only differing from Zygsena in the antennas, which are not so thick, 

 and insensibly fusiform and slender. The inferior palpi are shorter 

 and obtuse f . 



Atychia, Hoff., Illig., 



Where the antennae 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 tibiae is furnished with very 

 strong spines |. The 



Procris, Fab., 

 Approaches Atychia in the antennae ; but the inferior palpi are 

 shorter and not hairy. The wings are long, and the spurs of the 

 posterior tibite are small. 



P.stalices; Sphinx statices, L.; P. turquoise, De Geer, In- 

 sect., II, p. 255, iii, 8 — 10. Body glossy green, as if gilt; in- 

 ferior Avings brown ; antennae of the male with two series of 

 black setse, those of the females somewhat serrated. 

 In the other Lepidoptera of this division, the antennae of both 

 sexes are bipectinated or furnished with a double row of elongated 

 teeth. Those Avhich have a distinct proboscis form the subgenus 

 Glaucopis of Fabricius §, and those in which that organ is wanting, 

 or is not distinct, that of Aglaope ||.

Near the Syiitomides comes the genus PsicoTHOE, established by M. Bois-Duval, 

 in his Europ. Lepid. Index Method., and, according to him, distinct from all other 

 Zygsenides in its monillform antennfe and immaculate wings. It comprises but a 

 single species, P. Diivancelii, found in Bengal, by M. Diard and the late M. Du- 

 \auncel.
