76 R. NEWSTEAD — NOTES ON SCALE-INSECTS (COCCIDAE). — PAKT I. 



Puparium of the male. — Glassy opaque white ; the three bilateral transverse 

 ridges and also the anal cleft strongly pronounced ; dor sunt with a very deep 

 median transverse cleft, arising from which, on the posterior surface, is a relatively 

 large rectangular process of yellowish or creamy-white secretion ; the median 

 oblong cell or " coronet " on either side of the central cleft closely packed with 

 vesicular processes which, being darker in colour than the surrounding secre- 

 tionary matter, stand out in marked contrast to the rest. Length, 2*7 mm. 



Male (dried example) with one pair of white caudal appendages. Abdomen, 

 legs and antennae pale brown ; thoracic apodemes piceous ; wings with the costa 

 dull crimson. When placed in cold potash the body changes to bright pale 

 crimson, so that it is highly probable that in life the insect is of this colour. 

 Ocelli eight in number, of which four are ventral. Legs and antennae normal. 

 Length, inclusive of the anal filaments, 3 mm. ; wing, 1*7 mm. 



Uganda : Tern Forest, 13. vii. 12 (C. C. Gowdey). 



" On an unknown shrub in the depth of forest." 



All the females are apparently young adults and it is highly probable that 

 when older examples are discovered they will be found to be much larger ; 

 but it is very improbable that they will differ in structural details from the 

 young adults. Like the female of Lecanium {Eulecaninm) ciliatum, Douglas, 

 this insect also possesses a fringe of fine glassy filaments ; but it is markedly 

 distinct from this or any allied species and may, apart from the marginal fringe, 

 be determined by the form of the marginal spines, the antennae and the well 

 defined groups of spinnerets on the dorsum. The puparium of the male is also 

 strikingly characteristic and quite unlike that of any other species with which I 

 am acquainted. 



Lecanium (Eulecanium) somereni, Newstead. 



Lecanium mori var. somereni, Newst., Bull. Ent. Research, i, p. 187 (1910). 



Lecanium {Eulecanium) trcmae, Newst., Sond. Mitteil. Zool. Mus. Berlin, v, 

 pt. 2, p. 162, fig. 5 (1911). 



Having examined a fresh series of preparations of the Lecanium to which I 

 gave the specific name tremae, I have come to the conclusion that this insect is 

 synonymous with L. somereni, Newst. Furthermore there can, I think, be little 

 doubt that L. somereni is distinct from L,. mori, Signoret, and must take 

 specific rank. 



Lecanium (Saissetia) oleae (Bernard). 



Uganda: Entebbe, 26. viii. 11 (C. C. Gowdey). 



Found on the hard wood of an unnamed tree. 



All the examples are abnormally swollen by the attacks of Chalcidid 

 parasites. 



Lecanium (Saissetia) nigrum, Nietner. 



Uganda: Entebbe, 15. viii. 11 (C. C. Gowdey). 



The leaves of the food-plant (Anona muricata) were very heavily infested 

 with females in all stages of development.
