AFRICAN SCALE INSECTS (COCCIDiE), 97 



of anal lobes with three (possibly more) spines one of which (the most distal) 

 is of great length ; near the base of the lobes are several large spinnerets. 

 Derm with innnmerable spinnerets, those on the dorsum forming an indistinct 

 elliptic zone ; some of these (fig. 10, d,e) have two, others three orifices. Length, 

 2-25-2-75 mm. ; width, 1*50-2 mm. 



On Cofiee ; Namukekera, Entebbe, Uganda, 14. VIII. 1909 (C. C. Gowdey). 



There were several adult females from this locality ; and Mr. E. E. Green, 

 to whom they were sent in the first instance, has retained part of the series. 

 A single adult female was also found upon Baikea eminii, at Entebbe, 6. X. 1910 

 {C. C Goivdey), but this individual was associated with, and completely sur- 

 rounded by, a colony of the young forms and male puparia of a typical species of 

 Ceroplastes. 



The first examples submitted for examination were recorded in this Bulletin 

 (Vol. I, p. 67). The star-shaped tests of the young adult females so closely 

 resemble those of Vinsonia that I had at one time thought the insect referable 

 to this genus ; but having examined a longer series of specimens, including some 

 old adults, I have come to the conclusion that it should be placed in Ceroplastes, 

 for the following reasons : — (1) the test is formed of soft and easily soluble 

 wax ; (2) the ray-like extensions are not retained intact in the later stages ; 

 (3) the adult female is morphologically congeneric with Ceroplastes. 



Ceroplastes africanus, Gieen. 



On Acacia sp. ; Khartoum, Anglo-Egyptian Sudan, 22, VI. 1910 {H. H. King). 

 This large species seems to be fairly common in Egypt, jvidging by the number 

 of examples which have been submitted to me from time to time. 



Ceroplastes rusci (Linn.). 



On Crataecjus sp. ; Gizeh, Cairo, 31. VIII. 1910 {F. C. Willcocks). 



The food-plant is new ; but although this Coccid has been found upon several 

 different kinds of plants, it occurs most abundantly on the cultivated fig, to which 

 it is a very serious pest in parts of the Mediterranean area. 



Ceroplastes quadrilineatus, Newstead. 



One female only, on Amnia muricata; Masaka, Uganda, 10. IV. 1909 {C. C. 

 Goivdey). 



Ceroplastes ? sp. 



On Coflfee ; Uganda (C. C. Gowdeij). 



These are chiefly male puparia, with a few immature females. Not referable, 

 I think, to Ceroplastes vinsonioides, as they are quite typical in form, and have 

 too many lateral processes of white wax to agree in any measure with this 

 species. 



Ceroplastes ? sp. 



On Markhamia platycalyx ; Ndege, Uganda, 28. IV. 1910 (C C. Gowdey). 

 As the waxy coverings of the specimens are all damaged and the female 

 immature, it is impossible to determine the species.
