3rd, 4th and 5th, it bears 6 long hairs, the longest being from three to three and 
a half times the length of the antenna, there is also an inner lateral group of fine 
short hairs, almost tuft-like, though distinetly separated. Eyes large and conical. 
Legs long, slender; tarsus a little shorter than the tibia; ungues dentate; digitules 
slightly dilated. Lateral margin ot abdomen fringed with long hairs, those of the 
thoracie and cephalic areas much shorter; longest and stoutest anal hairs in two pairs, 
these are twice the length of the body, approximately. Derm with numerous eireular 
spinnerets (Fig. le), an:ıl long fine haris. Anal orifice resembling a minature Actinarian 
with elosed tentacles.

These specimens were enclosed in the same jar as Aspidoproctus armatus, Newst, 
so that they were in all probability found living together upon the same tree. 
The distinguishing features of tkis insect are the abnormally long anal aud 
antennal hairs in the larva. The marginal hairs in the adult are also very long; 
but in this respect the insect differs very slightly from Jcerya aegyptiaca Douglas. 
Examples referable to /cerya longisetosa were received also from „British East 
Africa, Kibwezi (auf einem Steppenstrauch), Scheffler 8. V., Nr. 345/07“, and from 
the same locality and by the same colleetor with the additional data „12. XII. 05, 
J.-Nr. 54/06“.

The specimens in all probability represent a new and undescribed species; but 
as they are all immature it is impossible to be quite sure as to whether they are 
so or not. 
Perissopneumon zimmermanni n. sp. (Newstead). 
Female, adult. Length 10—12; width 7—8,50 mm. Covered evenly with 
a fine granular layer of wax of an ochreous-white colour after immersion in alcohol. 
Ovate, slightly widened posteriorly. Margin rather thin; segmentation producing blunt 
tubercular projections; each projection carrying a short stout truncate waxen appen- 
dage. so that the margin presents a tooth-like appearance; sides above margin high 
and deeply concave; cephalic area with two strongly defined and slightly divergent 
ridges; thoraeic area convex, segments forming strong ridges; abdominal area concave, 
each segment with a distinet raised tuberele, the series forming a distinetly serrated 
submarginal ridge. Colour terra-cotta red to dull crimson; legs and antennae uni- 
colourous with body. „Secretionary flap“ over the rudimentary abdominal segments, 
greyish, but when ruptured the sublying material is smoky brown. Antennae normally 
of eleven segments of which the terminal one is much the longest; malformed examples 
are not infrequent, and in many cases the apical segments have disappeared entirely 
and appear in the preparations as if they had been arrested, from some cause or 
other, in development. Legs large and very setiferous; celaws with one strong ventral 
spine. Thoracie stigmata very large; abdominal stigmata in seven pairs, the median 
posterior pair being separated by a little more than twice the diameter of the vaginal
