Twelve subequal scutellar teeth, moderately long and each tippod with dark brown. Legs: Posterior femora less extensively brown, yellowish-testaceous on basal half, creamy-yellow on apical sixth and with a brown band between. Basal third of each posterior tibia creamy-yellow, tawny on remaining two-thirds. Posterior tarsi tawny. Two anterior pairs of femora yellowish-testaceous on basal two-thirds, a little lighter than on posterior pair, and creamy-yellowon the rest. The two pairs of remaining tibiae creamy yellow on basal half and, with their tarsi, the same colour as the femora elsewhere. Wings: Stigma pale, clear yellow, and veins light brown; subcosta and apical part of first longitudinal vein yellowish-brown.

Abdomen brown, translucent, a little darker and reddish in places. Sides of second segment narrowly fusco-piceous, this dark colour continuing onto apical corners of first segment. Genitalia: Hypopygium similar to that of allotype of P. azurea described above, including presence of protuberances on each side of epandrium, but differs in some characters. Lower edge of epandrium a little arched, instead of being straight. Styles more produced apioally, and almost straight below, but with a deeply sinuous upper margin.

Female.-The single female before me differs fiom the holotype of P. azurea in many features. Lower half of frons reddish-brown, lighter just above base of antennae-this light patch bordered on each side by a strip of tomentum which widens dorsally and which is enlarged inwards at the upper end, the enlargement of each side not touching the other but separated mowly. Dorsal part of from bluish-black. On each side of anterior ocellus a small, oval, diagonal spot of pollen. Thorax black, with cyanescent and violaceous reflections. Meaonotal pile moderately long. Mesonotal stripes silvery-grey, just meeting anteriorly, and narrowing very abruptly posteriorly midway between transverse suture and scuhllum, continuing to margin of scutellum as faint, broken, greyish lines. Posterior femora translucent and testaceous except for apical seventh, which is pale yellow. Wing veins light brown and thin. Scutellum fusco-piceouswith a strong admixture of brown on basal half, yellow on the rest. Fourteen scutellar teeth which are conspicuouslytipped with red-brown. Abdomen (

) very strongly carinate, deep and bowl-like-very broad and enlarged. Sides curve strongly backwards from prominent shoulders. Whole abdomen, including shoulders, dark red-brown-some fusco-piceous patches prewnt on most of the segments, apparently due to consolidation of the contents of the abdomen and their adherence to the tergites. A well developed sculpturation on posterior four segments-the first segment coarsely punctate. Transverse troughs on third segment narrow and quite deep, and outer end of each curves backwards. Troughs on fourth segment likewise narrow and quite deep, but linear. Vittae white and prominent. Fourth trnd fifth sternites brown, irregularly marked with black.

The specimens from Zanzibar have the thorax more intensely black, with very dark blue re3ections; two of the specimens have a creamy-yellow face, the other two are typical but have a very dark and conspicuous facial stripe. There is considerable variation in the colour of the abdomen, one specimen from Zanzibar being entirely fusco-piceous behind the first pair of vittae and over most of the first segment; the same specimen has pale antennae, the third segment being yellowish-brown. The male from Masiene has a very broad abdomen, shorter than in the other specimens, and which is dark fuscopiceous on the sides of the first three segments and entirely.so on the fourth and fifth segments, translucent reddish-brown elsewhere. The genitalia of each male paratype has been examined and all are similar to that of the allotype of P. azurea; in each case the lower edge of the epandrium is straight, the condition found in the holotype of scrupms apparently being unusual. The number of scutellar teeth varies from eleven to fourteen. Shortest paratype 5.4 mm., longest paratype 7.8 mm.</paragraph>

as they tend to be darker than those from the north and have slightIy shorter mesonotal pile. The males may be distinguished by the genitalia and by the longer antennae, while the females have a spot of pollen on each side of the anterior ocellus. The nine specimens taken at Aden by Yerbury (Verrall: 1898) probably belong to this subspecies. The specimens from Eritrea determined by
