AfIJICAN scale insects (CUCCIDiE). 'J.I 



ilnterior pair scarcely longer than the antenn£e. Anal lobes attenuated ; apices 

 with several stout spines ; and there is a single and very long slender spine, 

 arising from the ventral surface, the tip of which projects beyond the apes of 

 the lobe. Stigmatic clefts shallow ; spines rather short and bluntly pointed, 

 central one a little more than twice the length of the two laterals. Marginal 

 spines (fig. 7, c) long ; they are also set closely together and are less deciduous on 

 the cejjhalic margin than elsewhere. Derm cells minute, simj^le, and very widely 

 separated. There are a few minute sjaines just in advance of the anal lobes. 

 Length, l-75-2'50 mm. 



On Citronella grass ; Entebbe, Uganda, 25. II. 1910 (C. C. Gowdey). 



The insects were so numerous that they almost covered the leaves of the food- 

 plant ; and although so abundant quite 98 per cent, of them had been destroyed 

 by a Chalcidid parasite ; it is highly probable, therefore, that the markedly 

 convex nature of the body was caused by the parasites, so that too much import- 

 ance cannot be attached to this character. 



This Coccid somewhat resembles a miuature example of Lecaniuin elontjatum, 

 Signoret, but is clearly distinct ; apart from its small size it may be easily dis- 

 tinguished by the character of the antennie, and the closely set marginal spines. 



I am extremely indebted to Mr. E. E. Green for giving me the opportunity of 

 describing this insect ; I have pleasure also in adopting the MS. name which he 

 has given to it. Figures of the antenna and marginal spines of Lecaniam 

 eloayatum, Signoret, (fig. 7, d, e) have been added for convenience of reference. 



Lecanium (Eulecanium) tremae, Newstead. 



On " Nsambyia " ; Palissa, Uganda, 1. XII. 1910 (C. C. Gowdeij). 



This species was described, quite recently, from examples collected by Prof. 

 A. Zimmermann, at Amani, German East Africa. The females bear a strong 

 superficial resemblance to Lecanium persica, but may be readily distinguished by 

 the very distinct and strongly rounded ridge to the margin, as well as by other 

 impoi'tant morphological characters. 



Pulvinaria jacksoni, Newstead. 



On Cotton J Kyerime, near Lake Salisbury, Uganda, 10. XII. 1910 (C. C. 

 Gowdey). 



This remarkable Coccid has hitherto been recorded* only from the West 

 Coast of Africa, where it was found infesting Cacao and a species of Ficus, 

 In my original description of the insect, I called attention to the presence of two 

 large flaccid tubercles in the stigmatic clefts as being one of the marked specific 

 characters. In the examples from the Uganda Protectorate these processes are 

 not visible, but I believe, however, that they have been completely destroyed by 

 excessive maceration in the caustic potash. However this may be, the great 

 length of the ovisac and its curious fungoid appearance will serve at once to 

 distinguish this from any other known species of the genus.
