An insect of a widely acquired geographical range, particu- 

 larly, however, in Mediterranean latitudes — occurring in Portu- 

 gal, Spain, the south of France, Italy, Sardinia, Sicily, Egypt, 

 Barbary, &c. It is abundant also in the Azores, Madeiras, 

 and Canaries, and has been reported even from Chili. At St. 

 Helena it has been met with both by Mr. Melliss and the late 

 Mr. Bewieke ; and I have seen examples of it from the same 

 island in the collection of Mr. A. Fry.

Two examples only of this beautiful Bcmhidiinn (which be- 

 longs to the same group as the Em-opean B. varium and jf a m- 

 midatum) were taken by ]\Ir. ]\Ielliss; but I have no note as to 

 the precise locality. It is well distinguished by its dull brassy- 

 green head and prothorax, and lurid-testaceous elytra — the 

 latter of which are ornamented with a number of darker tascias 

 and cloudy patches, forming (on each elytron) a large sub- 

 apical blotch, a postmedial zigzag (or deeply dentate) fascia, 

 and two squarish antemedial spots placed in an oblique direc-
