2. Ceraiina placida. 

 C. nigro-senea punctata, clypeo macula alba ornato ; alis hyalinis. 



Female. Length 32-4 lines. Dark bronze colour, with tints 

 of bright green on the head and thorax; a triangular spot on the 

 clypeus anteriorly, and a similar spot on each side of it touching 

 the eyes, the latter sometimes continued up the inner orbit of the 

 eyes, yellowish white; a narrow line behind the eyes; the head 

 strongly and closely punctured ; the flagellum piceous beneath. 

 Thorax strongly punctured, with a smooth shining space in the 

 middle of the disk ; the mesothorax with three central smooth 

 impressed lines, and an abbreviated one outside of them opposite 

 the tegulae ; the wings sub-hyaline, the nervures blackish ; the 

 legs nigro-piceous ; a process in front of the anterior femora at 

 their base, which is produced into an acute spine on each side. 

 The abdomen strongly punctured, the three apical segments 

 rugose ; beneath bright green. This species closely resembles, 

 if it be not a local variety of, the Ceraiina punctulata of Spinola, 

 described in the " Annales de la Societe Entomologique de 

 France," 1841, p. 139.

 Apis cordata, Linn. Syst. Nat. i. 955, 15 ? 

 This I believe is only a highly coloured and beautiful variety 

 of the E. cordata; every intermediate shade of colour occurs 

 between specimens which are entirely green, and those with the 

 abdomen of a fiery copper colour, the latter being the E. analis 

 of Westwood.
