On a Colleetion of Coceidae and Aleurodidae, of the Berlin Zoological Museum. 163 
well preserved examples there are also numerous small particles of white secretion 
scattered over the whole of the dorsum. Colour generally dark castaneous though 
a few examples are much paler. Examples crowded together on slender twigs are 
laterally compressed so that the width is considerably less than the length. 
Hemispherical forms measure: Length 3,50, width 2,75—3 mm. The compressed 
forms 3,50—4,25 long and 2,25—3 mm wide. Antennae (fig. 6a) of 8 segments, 
nearly equalling the length of the anterior pair of legs; the latter shorter than either 
the mid or posterior pair. Derm cells rounded and oval, small, but there is a group 
of much larger cells immediately in front of the anal orifice. Stigmatie spines (fig. 6 b) 
three, median spine more than twice the length of the lateral ones. Marginal hairs 
(fig. 6€) minute: some are simple, others serrated. Margiral spinnerets minute. Anal

lobes with the base and outer edge approximately equal; apices very obtuse. (Grenital 
spinnerets ceircular, and scattered between these are a number of short blunt con- 
cical spines.

This inseet closely resembles Lecanimm persicae Var. ribis. Sign. et. Auct.; 
but is much less rugose, has a non-reticulated derm., eight segments to the antennae 
and is further distinguished by the blunt conical spines near the genital orifice. 
Lecanium (Saissetia) oleae (Bernard). 
Several examples, all adult females.. Many of them are demaged; and not a 
few are parasitized.
