ROBERT NEWSTEAD. 



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



The affinities of this insect are with P. maxima, Green, and P. jacksoni, Newst., 

 but it differs from both in having pointed marginal spines, and from the latter species 

 by the much denser and shorter ovisac. 



Pulvinaria elongata, sp. nov. 



Female, adult (fig. 13, e). Extremely elongate or elliptical, extremities more or 

 less equally attenuated ; dorsum convex, cephalic region flattened. Colour, in life, 

 varying from very pale crimson to bright rosy flesh-colour, with two more or 

 less distinct, longitudinal lines of bright crimson, the latter frequently interrupted 

 by a black wavy loop-like line, due apparently to a portion of the alimentary tract

(? Malpighian tubules). Dry cabinet specimens are pale buff, with a broad median 

 suffused area of smoky brown or red-brown, and often with a well-defined median 

 keel. The ovisac is very short indeed, projecting but slightly beyond the margin ; 

 it extends anteriorly, usually as far as the region of the eyes. Antennae (fig. 13, a) 

 normally of eight segments, of which the 3rd is slightly the longest; in two 

 individuals the antennae are asymmetrical, one being composed of seven segments 

 (fig. 13, b) the other of eight ; in the former the 4th is twice the length of the 3rd,
