This insect is not found in the west of England. Mr. Curtis took 

 it some years ago in the month of June at Ambleside, "Westmoreland. 

 In describing the species he has stated that the colour is obscure in 

 certain lights. It might have had an aeneous reflection, particularly 

 if an old specimen was examined. I had many opportunities of ex- 

 amining his bees ; and they were certainly the same species as mine 

 from Scotland. Mr. Curtis so named them himself ; and I gave him 

 both sexes. The colour of the abdomen of the female is black, occa- 

 sionally reflecting an obscure aeneous tint. Dr. Gerstaecker thinks 

 my 0. parietina distinct from that described by Mr. Curtis. This is a 

 mistake : the insects have been most carefully compared, and Curtis 

 agreed with me in considering them identical. The only other 

 localities known are Bridgend (Glamorganshire), Loch Rannoch 

 (Perthshire), and the Grampian Hills.

 Thorns. Hym. Seand. ii. 246. 



Female. Length 4-4^ lines. — Black ; the head and thorax closely 

 punctured ; the anterior margin of the clypeus truncate ; the face 

 with thin black pubescence, a few fulvous hairs at the insertion of 

 the antennae and on the posterior margin of the vertex ; the 

 flagellum of the antennas obscurely rufo-piceous beneath towards 

 the apex. Thorax densely clothed above with bright rufo-fulvous 

 pubescence ; wings subhyaline, clouded at their apical margins ; the 

 pubescence on the legs and thorax beneath black. Abdomen 

 shining, subglobose, and with fine shallow punctures ; the two basal 

 segments with rufo-fulvous pubescence, less dense than that on 

 the thorax ; on the other segments above, and on all beneath, it is 

 black. B.M. 



Male. Length 4-4| lines. — Nigro-aeneous ; the face densely clothed 

 with long white pubescence, at the insertion of the antennae it is 

 pale ochraceous : the antennae nearly as long as the head and 

 thorax, the flagellum pilose beneath. Thorax thinly clothed on the 

 disk with long pale ochraceous pubescence, at the sides and beneath 

 it is white ; the anterior femora densely fringed with white pubes- 

 cence, on the rest of the femora, tibiae, and tarsi it is of the same 

 colour, but thinly scattered ; the posterior femora and tibiae snb- 

 incrassate ; the wings subhyaline and iridescent. Abdomen ovate, 

 shining, and closely punctured, the apical margins of the segments 

 impunctate and very glossy ; at the base, sides, and apex a long
