 the case, the title proposed for the species by Mr. Hope will 

 have to be retained.

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

 island in the collection of Mr. A. Fry. 



Genus 4. Bembidium.

(Subgenus Notapkus, Dej.) 



5. Bembidium Melltssn, n. sp. 



B. oblongum, subopacum, alutaceum ; capite prothoraceque subasneo 

 nigro-viridibus, hoc brevi subcordato, utrinque intra angulos pos- 

 ticos profunde impresso (impressionibus extus striola terminatis) ; 

 elytris depressiusculis, profunde striato-punctatis (striis postice 

 evanescentibus), lurido-testaceis sed fasciis maculisve disjunctis 

 nigrescentibus ornatis ; an tennis pedib usque piceo-testaceis, illis 

 versus apicem horumque femoribus paulo obscurioribus.

Two examples only of this beautiful Bembidium (which be- 

 longs to the same group as the European B. varium and Jlam- 

 mulatum) were taken by Mr. Melliss ; 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 fasciae 

 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- 

 tion (from the shoulder) on the fore disk. The elytral striae
