6 ROBERT NEWSTEAD. 



one short, median, and three on each side, the lateral rows continuous behind ; 

 intervening spaces with somewhat granular wax ; margins with outstanding 

 hairs, which appear more numerous and much longer posteriorly. Venter, in the 

 oldest examples, with a relatively thin layer of white wax, but this, in the specimens 

 submitted, does not form a distinct ovisac or pad. Antennae of nine to ten 

 segments; in two instances they were asymmetrical ; terminal segment not quite 

 so long as the two preceding ones together ; there is a long slender spine on the 

 second, and long stout hairs on the succeeding ones, in addition to which there 

 are two to three very long slender hairs on the terminal segment, one of which is 

 equal in length to the last two segments together. Legs very robust and long. 

 Derm markedly hirsute ; spinnerets large, circular and almost as numerous as 

 the hairs. Stigmata relatively small. Margins with immensely long stout hairs, 

 the longest being three times the length of the antennae. Many of the marginal 

 hairs are dilated and frayed distally and sometimes present three distinct, lateral 

 ridges, resembling somewhat the proximal half of the scapula of a mammal in 

 miniature ; these are clearly malformations due, possibly, to injury by abrasion. 

 Length, 5*5 mm.-6'5 mm. 



Female, second stage. Waxen covering similar to that of the adult, but the 

 median and submedian rows are not so pronounced ; colour bright yellow, or 

 rarely pure white. Antennae of seven segments, of which the third and seventh 

 are the longest. Derm sparsely hirsute ; pores much fewer than in the adult. 

 Marginal hairs of immense length, the longest and stoutest arising from the 

 abdominal segments ; these are, when perfect, four times the length of the 

 antennae, or slightly longer than the entire length of the insect. Length, 2-2*3 mm. 



Larva. Antennae with the terminal segment markedly incrassate, with five 

 immensely long, stout, lateral hairs ; the largest about twice the length of the 

 antenna. Derm thickly set with fine long hairs ; margins with similar but slightly 

 longer hairs ; terminal segment of abdomen with three pairs of long hairs, of which 

 the median pair is about half the length of the others ; the two pairs of longest 

 hairs three times the length of the antenna, or about one-fourth longer than the 

 body. 



Gold Coast: Aburi, on Thespesia sp. (W. H. Patterson). 



The general appearance and arrangement of the cereous coverings of the old 

 adults resemble somewhat those of the young adult $ of Icerya seychellarum, Westw. ; 

 but the strongly hirsute character and great length of the marginal hairs may 

 readily serve to distinguish it. That the colour of the waxy covering should vary 

 between bright yellow and white is rather remarkable, but the former, so far as 

 one can judge from the few examples at hand, is the predominant colour. There 

 is no admixture of the two colours in the same individual ; all are either entirely 

 white or entirely bright yellow. 



Palaeococcus caudatus, sp. nov. 



Female, adult. Apparently without any trace of an ovisac ; dorsum covered 

 with short stout waxen processes, white or dirty white in colour and thickly felted 

 in texture ; these processes are arranged in seven rows : the median row much 

 the broadest and coalescing, more or less ; the other rows almost uniform in size
