Var. 1. (Imperiale.) Entirely of a deep dark blue or purple, 

 with the exception of the flagellum of the antennae and the tarsi, 

 which are black : the venter green : the wings edged with a broad 

 fuscous band : the head and thorax very coarsely punctured : 

 the abdomen more delicately, and very gibbous ; the latter 

 pubescent, especially the last segment, which is also much 

 acuminated. (Length, 3 J lines.) 



Var. 2. (Bidentulum.) Of a brilliant bluish green, excepting 

 the disc of the abdomen, which is of a shining blackish green, 

 punctured, and the form of the entire abdomen similar to the 

 preceding, but not more than two-thirds of its size, and not at all 

 pubescent : the antennae, wings, and legs, as in the preceding. 

 (Length l—2h lines.) 



Var. 3. (Firide.) When alive entirely of a brilliant green; it 

 differs from the preceding in the green not having a blue tinge ; 

 after death, the head and thorax change to a deep blue green, and 

 the disc of the abdomen becomes black : the punctures as in the 

 last, and, like it, it wants the pubescence of the first variety, but 

 the wings, antennas, and legs are similar, but it differs in the 

 terminal segment of the abdomen being much more rounded, and 

 the abdomen itself not so gibbous. (Length, 11 — 2\ lines.) 



Var. 4. (sEnea.) Entirely of a dark aeneous tinge, nearly black : in 

 sculpture and in the form of the abdomen, it resembles Vars. 1 and 

 2, as also in its legs, wings, and antennae : from Var. 2 it differs 

 only in colour. (Length, 2 lines.) 



Var. 1, of which I have one specimen only, was taken at 

 Bexley, by Mr. Bainbridge, who kindly gave it to me ; it stands 

 in the cabinet of the British Museum as the imperiale of 

 Leach ; it is certainly Var. 2 of the Chrysis ccerulea of 

 Dahlbom. Vars. 2 and 3, I have taken in Battersea-fields ; 

 Var. 2 appears to be the bidentulum of St. Fargeau ; Var. 3 

 I have called viride, from its colour when alive; and I have
