304 PROFESSOR R. NEWSTEAD — NOTES ON 



with a single rectangular chamber (fig. 3d), the distal lip of which has three 

 angular projections ; at the base of each of the glands a group of minute pores 

 (fi£. 3^2) which collectively present a reticulated appearance ; the first two 

 pairs have relatively huge subcutaneous sclerites. In addition to the large 

 paired glands are many others (fig. 3<?) of a smaller size and with dilated sub- 

 cutaneous tubes. Integument of the dorsum almost covered with minute and 

 rather bluntly pointed spines ; numerous minute circular spinnerets and large 

 glands, apparently of a similar form to the smaller ones found on the venter — the 

 densitv of the chitin renders these organs somewhat obscure. Margin of large 

 ventral orifice (? anal orifice or marsupium) with a broad band of densely packed 

 and minute spinnerets. Marginal spines (fig. 3/) straight or slightly curved and 

 slightly dilated ; in the midst of these spines at somewhat regular intervals are 

 well-defined groups of fine hairs, about four times the length of the spines. 



Length 20-25 mm. ; width 16-20 mm. ; height 10-13 mm. 



Southern Nigeria : Ibadan, 7. vi. 13, on Silk Cotton Tree {Ceiba bombax) 

 {Dr. W. A. Lamborn). 



Dr. Lamborn sends the following information regarding this insect : — 

 " Coccids from branches of a fallen cotton tree, I think Ceiba bombax, the leaf 

 and seed of which are now sent. The tree, which is known as the African Fetish 

 Tree, is about our largest forest tree, being I should estimate often 130 to 140 

 feet in height and of enormous girth. The insects were first seen on 7th June 

 1913 here and there, by no means numerous and never more than two together, 

 on the under side only of boughs averaging 7 or 8 inches in diameter. Branches 

 larger than these were unaffected. 



" The height from the ground of the affected boughs was, by tape measure, 

 between 98 and 104 feet. The bark on them was about ^ inch in thickness and 

 on stripping it off one found in many cases on the light yellow surface exposed 

 under them a dark brown discoloration about the size of a 3rZ. piece. 



" The insects being grey in colour harmonised well with the bark. Many were 

 quite dead and had cracked open when the tree fell so as to expose an enormous 

 number of tiny cheese-coloured ovoid eggs. Many of the boughs had holes, 

 evidently made by borers of some sort, and on splitting them open, cavities were 

 found tenanted by other Coccids. Two of these which were the size of a large 

 pea were black, and the others which were very numerous were minute and 

 flesh-coloured." 



This remarkable Coccid somewhat resembles Aspidoproetus pertinax, Newst., 

 but may at once be distinguished by its markedly greater dimensions, the presence 

 of the double mammiform process in the middle of the dorsum ; and also in 

 having eight instead of nine segments to the antennae. 



Lindinger* has sunk Aspidoproetus, Newst., under the genus Lopliococcus, 

 Ckll.,t but leaves us still in doubt as to whether they are congeneric or not. 



I had already stated! that the former may have to sink as a synonym of the 

 latter ; but that it remains with Cockerell to decide as to whether his Lophococcns
