Plates I. and II. 



Though not our first meeting with examples of this 

 genus, we were, last year at Fusio (Tessin, Switzerland), 

 attracted by a species that we believed to be 0. gloriosa, 

 which led to our taking an increased interest in the 

 OrintB. These were rather large Ckrysomela-like beetles, 

 some specimens being about half-an-inch long. Their 

 coloration varied immensely, through blue, blue-green, 

 green with a blue stripe, bright metallic grass-green, and 

 the same with blue or coppery stripes, the latter being 

 very handsome, and fully justifying its various synonyms 

 of gloriosa, superba, speciosa. Some of the blue-green 

 specimens were so dark as to be almost black. The most 

 dissimilar forms were secured in copula, and these with 

 series of the several forms were exhibited at the meeting 

 of the Entomological Society on February 7th, 1900. This 

 striking variation suggests these beetles as very suitable for 

 experiments on heredity and variation, especially as our 

 experience this year shows that they are very easy to rear.
