74 R. NEWSTEAD — NOTES ON SCALE-INSECTS (COCCIDAE). — PART I. 



Ceroplastes africanus, Green. 



Northern Nigeria : Kogin Sirikin Pawa, xi. 1910 (J. J. Simpson). 



In none of the four examples before me is there any sign of the nipple-like 

 prominence noted by Green,* neither is there any trace of lateral waxen plates. 

 In its external characters therefore, it agrees best with Ceroplastes egbarum, 

 Cockerell ;t but this species has, according to its author, " no lateral humps," 

 whereas the examples taken by Dr. J. J. Simpson have well-marked thoracic 

 and sub-anal humps or tubercles ; clearly therefore they cannot be referable to 

 C. egbarum ; and although Green makes no reference to the presence of these 

 organs in C. africanus, yet he figures them {he. cit. fig. lb) as being present in the 

 young adult female. Unfortunately I was unable to dissect out the antennae, so 

 that I cannot say if these organs agree with those of typical C. africanus. All 

 that I can add regarding these structures is that the first to the fourth segments 

 agree with the corresponding segments noted and figured by Green (loc. cit. 

 fig. 1/). One other discrepancy that I have noted in Simpson's specimens is 

 that the stigmatic spines at the extreme margin are simple, stout and rather 

 long, not " small conical ones " as noted by Green ; but inside these longer 

 spines are innumerable minute conical ones occupying a large area which in form 

 and extent is almost identical with the stigmatic area in C. ugandae, Newst.J 



Possibly the Nigerian examples may prove eventually to be a well-marked 

 race of C. africanus, but much more material is needed before one can definitely 

 decide upon this question. 



Ceroplastes ugandae, Newstead. 



Uganda: Entebbe, 12.viii. 11 (C. C. Gowdey). 



Found on Anona muricata. 



The organs described and figured by me in this Bulletin (vol. ii, p. 94, fig. 8c) 

 as " parastigmatic glands " are undoubtedly clear spaces in the dense chitin to 

 which extremely minute spines are attached. I should point out also that this 

 Coccid presents several characters in common with Ceroplastes fulleri, Ckll.,§ but 

 in the description of the latter Cockerell makes no reference as to the presence 

 of tubercles on either side of the caudal process or to those which occur over 

 the stigmatic clefts ; neither does he mention the papillae which render the 

 integument so strikingly characteristic in C. ugandae. 



Lecanium (Eulecanium) filamentosum, sp. n. 



Female (f adult), dried examples. — Orange brown, integument shining. Form 

 oblong-oval, narrowed anteriorly and with one side generally more distinctly 

 curved than the other ; median area slightly raised, marginal zone very broadly 

 flattened and translucent ; margin with a distinct fringe of rather widely separated, 

 short, glass-like filaments, all of which are attached to the tips of the truncated
