METOPSILUS. 155 



segments. The caudal horn is short, very slightly 

 bent, sometimes almost obsolete. The chrysalis is 

 enclosed in a loose cocoon formed of leaves, and is 

 never buried beneath the soil. The perfect insects 

 are very beautifully coloured, and it is observable that 

 the abdomen is always 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.
