longest varying between one-third and one-half the length of the antenna. Pores- 

 circular and very numerous ; these are of two sizes : the larger (fig. 5, a) being; 

 twice the diameter of the others. Antennae (fig. 5, b) of eleven segments ; 

 terminal segment much the longest but scarcely wider than the preceding one.

 a, pore ; b, antenna ; e, leg 



Legs (fig. 5, c) long ; femur very short ; claw faintly bidentate, digitules simple 

 hairs ; underside of tibia very hairy. Eyes truncate. Stigmata large, slightly 

 longer than the tarsus. 



Gold Coast : Aburi, on Tectona sp. {W . H. Patterson). 



The form and arrangement of the waxen appendages are very like those in I eery a 

 aegyptiaca, Doug., but the bright pale yellow colour is distinctive and the structural 

 details differ. 



Margarodes buxtoni, sp. nov. 



Female, adult. Form rather elongated and very tumid. Derm almost completely 

 covered with a layer of white, mealy secretion. Colour in alcohol, dull brownish- 

 crimson. After maceration in KOH the body assumes a broadly ovate form 

 (fig. 6, a). Derm, on both surfaces, finely but markedly pubescent, the individual 

 hairs relatively long and exceedingly slender. Pores (fig. 6, /) circular, with a 

 central opening and numerous minute ones surrounding it ; these organs are 

 almost as numerous as the hairs, more especially so on the terminal segments of 

 the abdomen. Antennae (fig. 6, b) short, stout, and widest proximally, composed 

 of eight segments, each (with the exception of the last) with a well-defined chitinou& 

 band ; distal segment with several minute stout spines, and two groups of long 

 fine slender hairs ; the remaining segments are apparently nude, but of this one 

 cannot be quite certain, as the innumerable hairs on the surrounding integument 

 are lying superimposed over a great portion of the antennal segments. Anterior 

 leg (fig. 6, c) large, stout, and more than twice the size of the other limbs ; claw 

 densely chitinised and distinctly articulated with the exceedingly short tarsal 

 segment ; tibio-tarsal articulation well defined, and immediately below this is a
