162 Robert Newstead: 
Length 1 mm. 
Habitat: D. Ost-Afrika, Magrotto; August: 1902, auf Cofea arabica. Prof. 
A. Zimmermann (Nr. 15). 
The puparium of this insteresting species closely resembles that of Asterole- 
canium thesü (Doug.) but it is easily distinguishable by the great length of the spout- 
like caudal projeetion; and also by the greater length of the marginal fringe. The 
female is also distinguishable by the five dorsal rows of figure-of-8 spinnerets. This 
insect does not moreover produce pits or depressions in the food-plant. 
Lecanium nyasae n. sp. (Newstead). 
Female adult. Very elongate; front slightly produced; strongly wrinkled 
transversely; posterior margin broad and flat, with 3—4 clearly defined narrow 
ridges (carinae). Colour dark chocolate brown in alcohol, but when dry changing 
to a pale-brown, the dorsal area presenting innumerable minute blackish specks. 
Antennae (fig. 5a) of eight segments, the fifth being slightly shorter than the fourth. 
Fig. 5a—d. Lecanium nyasae. 
Legs normal; lower digitules (fig. 5b) very broad. Stigmatic cleft (fig. 5c) shallow; 
spines simple, straight; laterals less than half the length of the median spine. Marginal 
spines (fig. 5d) short, stout, tips emarginate or divided so that they appear bidenlate. 
Anal lobes (operculum) narrowed and rounded apically. Derm cells absent (There 
is no trace of these in the macerated examples); but there are innumerable spinnerets 
with minute pyriform subcutaneous tubes. 
Length 7—7,50; width 4—4,25 mm. 
Habitat: Nord-Nyassa, Rungwe-St. Utengule. 9/10. XII. 98. Fülleborn 8. G. 
This unusually large species belongs to the group of which Zecanium longulum, 
Doug. and /. schini, CK. may be taken as types. It differs from these and also 
other allied species by the total absence of derm cells, the well marked character 
of the marginal spines, and the presence of very distinet marginal carinae. 
Lecanium (Eulecanium) tremae n. sp. (Newstead). 
Female adult. Form hemispherieal, slightly narrowed anteriorly; rarely with 
faint traces of H-shaped carinae; margin forming a very distinet rounded ridge; 
integument shining but with a few irregular shallow wrinkles or depressions, and in
