 In many instanres in the present [ilate where the sexual differences were slight, I have only sliown the male insect. In S. Pavonia minor 

 the female is princip:illy distinguislieil hy paler colouring, and being somewhat larger in size. In E. Lanestris the female has the antenua simple, 

 and the tuft at the tail much larger and more compact. P. Populi differs only in size, the female being considerably larger, but with simple 

 antennx. C. Neustria is very variable ; the sexes arc much alike, except that in the female the antenna; are less strongly pectinated. In 

 T. Crata;gi the female is more dusky, and less distinctly marked. 



All the insects in the present pUte (with the exception of Bt Lincstiis from the Britisli Museum) are from fresh and beautiful specimens, 

 kindly furnished by Mr. II. DouUleday. The Caterpillars arc from Iliibncr, except that of O. Potatoria, which is from nature. H. N. H. 



SATURNIA*, ScHR.^NK. (ATTACUS, Germar, PAVONIA, Hubner). 



The moths of this genus prcciniucntly take the lead of all the Linnsean species of Bonibyx, on account of 

 the large size of the exotic species, most of which have the wings large, rounded, and ornamented with eye-like 

 and more or less fenestrated .spots. The antenna; have each joint 4-peetiiiated, the pectinations in the male 

 being very lonrr ; tiio spirtil tongue and palpi are obsolete, or very short and pilose. The collar is generally 

 coloured like the fore margin of the wings. The abdomen is short and very mbust. The larva of the European 

 species are naked, each segment of the body girt by tuberculated rings, the tubercles emitting tufts of hairs. 

 The pupa is inclosed in a pear-shaped cocoon, one end of which has tlie silken threads arranged with singular 

 instinct to allow the egress of the perfect insect as soou as disclosed, and which yet prevents the entrance of 

 other insects. The genus is very numerous in exotic species, the arrangement of whicli requires revision. We 

 however possess only a single species.

This species, which from its beauty has received the name of the Emperor J\Ioth, varies from 2| to 3^ inches 

 in the expansion of its fore wings, which in the males are of a grey brown, but paler grey in the females ; a 

 pale oblique bar, bordered on each side with black, runs across near the base, succeeded in the centre by a pale 

 oblong patch, within which is a beautiful black eye-like mark inclosing a yellowish ring, with a slender pale 

 blue crescent. This is succeeded by a wavy fulvous stripe edged with black, and terminating in a black patch
