METOPSILUS.

segments. The caudal liom is short, very slightly 
bent, sometimes almost obsolete. The chrysalis is 
enclosed in a loose cocoon formed of leaves, and is 
never hurled beneath the soil. The perfect insects 
are very heantiftdly coloured, and it is observable that 
the abdomen is alwayn longitudinally or obliquely 
striped, an arrangement different from what ob- 
tains in the two preceding genera, which have that 
part of the body ornamented with transverse bands 
sometimes of different colours. Viewed in relation 
to the form of the larvae, as well as to the appearance 
of the perfect insects, the species which we have 
placed together, under the above name, form a very 
natural group.
