with bluish reflects and a thin whitish pollen covering all the segments except 
the last one. Frons of the male more or less narrow, not broader than the 
ocellar triangle; male genitalia in lateral view show acute paralobes and 
straight mesolobe. Females with the middle frontal stripe three times bioadei 
than one of the parafrontalia; average size 9-11 mm. . caerulea R.-D.

black interspaces. In both sexes the thorax is of a dark blue metallic colour 
with scarce pollen and the abdomen of a glittering bluish-green colour de\ oid 
of pollen and with a distinct dark longitudinal median stripe upon the second 
and third segments. Frons in the male distinctly broader, being about twice 
as broad as the ocellar triangle; the male genitalia with the paralobes broadly 
obtuse and with curved mesolobe. Parafrontalia of the female broader, the 
middle frontal stripe being twice as broad as one of them; average size 
11-14 mm. .....••••• azurea hall.

Thorax metallic, greenish-black to bright green colour with grey pollen and 
three nearly equal longitudinal stripes of the ground colour. Abdomen 
metallic dark bluish-green to bright cupreous or golden-green colour with 
scarce silvery pollen; anal segment varies always from cupreous to golden-

1 The Catalogue of Palaeai die Diptera, p. 444, contains also the genus Philo inis Meineit as 
a synonym of Protocalliphora. The late Dr Nielsen, 1911, p. 207, pointed out this error, which is 
not mine (only pp. 1-597 of vol. hi being my work) but that of Brauer, 1894, p. 568.
