86 MANDIBULATA. — COLIilOPTERA. 



ceouSj rather convex^ shining, gi*een-brass, obsoletely strigose, a slight channel 

 down the centre, a large bent impunctate fovea on each side at the base : 

 elytra oblong-ovate, rather convex above, green-brass or coppery, very deU- 

 cately striated, and obsoletely granulated, the striae with very minute im- 

 pressed dots, but with three larger ones on each elytron, the first near the 

 third stria from the suture, the other two near the second ; the margin has 

 an interi^jpted row of impressed dots, and is entirely of a bright pale yellow : 

 the body beneath is brassy-green, smooth, and shining : the thighs are stout, 

 pitchy-black ; the tibise, and sometimes the base of the thighs, pale testa- 

 ceous, the former fuscous at the tip : the tarsi brownish. The male has the 

 elytra shining, the female obscure. 



Ag. marginatum used to be esteemed a scarce species, but it 

 occurs plentifully in several places. The Rev. L. Jenyns finds it 

 common in the fens near Ely; and I have taken it abundantly in 

 Eattersea-fields, and in other parts near London.

A splendid insect: head obsoletely striated, shining, green, or green-gold: 

 mouth pitchy-black : palpi and antennae black, the latter brassy at the base : 

 thorax with its disc slightly convex, brassy-green, or golden, slightly but 

 thickly strigose transversely, with a punctate impression on each side at the 

 base : elytra ovate, above moderately convex, shining red-copper, with the 

 margin green-brass, slightly punctate-striate, the interstices obsoletely gra- 

 nulated, and the third from the suture usually adorned with six rather deeply 

 impressed dots, two of which are placed near the base of the third stria, and 

 the other four adjoining the second ; the margin is also furnished with a series 

 of suboceUated dots : the body beneath shining greenish-brass, the sides sub- 

 punctate : the thighs greenish-brass : the tibifE and tarsi black. 



The colour of the upper surface varies extremely, from every shade of brilliant 

 red-copper to splendid hues of green, gold, purple, and violet ; it is sometimes 

 found nearly black ; and the number of impressed dots between the second 

 and third stria from the suture varies from five to eight. 



Previous to the year 1812, few cabinets could boast the posses- 

 sion of this beautiful species. In July of that year I took a single 

 female in a water-course in the hollow of Coombe-wood, and the 

 following year I met with the insect by dozens in the same place ; 

 also in Battersea-fields and near Hertford I found a few ; and in 

 the same season it was taken, I believe plentifully, in Norfolk, and 

 sparingly in Epping-forest, and in several places near London ; 

 but it has subsequently disappeared.
