In many instances in the present plate where the sexual differences were slight, I have only shown the male insect. In S. Payonia minor 
the female is principally distinguished by paler colouring, and being somewhat larger in size. In E, Lanestris the female has the antenne 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 
antenne. CC. Neustria is very variable; the sexes are much alike, except that in the female the antenne are less strongly pectinated. In 
T. Crategi the female is more dusky, and less distinctly marked. 
All the insects in the present plate (with the exception of Ek Lanestris from the British Museum) are from fresh and beautiful specimens, 
kindly furnished by Mr. H. Doubleday. The Caterpillars are from Hiibner, except that of O. Potatoria, which is from nature. H. N. H.

The moths of this genus preeminently take the lead of all the Linnean species of Bombyx, 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 antenne have each joint 4-pectinated, the pectinations in the male 
being very long; the spiral 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 robust. The larve 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 the silken threads arranged with singular 
instinct to allow the egress of the perfect insect as soon as disclosed, and which yet prevents the entrance of 
other insects. The genus is very numerous in exotic species, the arrangement of which requires revision. We 
however possess only a single species.
