a.s in the shorter spines, and all have immensely long filamentous ends, so 

 that they may be more correctly described as spinose hairs ; owing to the 

 fine filamentous nature o£ the terminal portions o£ these appendages it is a 

 somewhat difficult matter to determine their exact length, and some of them 

 may be even longer than is shown in the accompanying figure. In addition 

 to these there are also a few short lanceolate spines (fig. 1 c) irregularly inter-^ 

 spersed between the longer appendages. Antennse of four segments, the 

 articulations of which are in most cases very faint ; but they bear a close 

 resemblance to those described herein as belonging to the male larva. Legs 

 long, sparsely setose ; tarsi as in the larva of the other sex (see fig. 2).. 

 Mentum biarticulate and finely setose ; filaments of great length lie coiled 

 on either side. 



Larva of male (fig. 2). — Ellipsoidal. Buccal organs obsolete. Antennse' 

 (fig. 2 a) of four segments, the third being slightly the longest ; they are 

 about equal in length to the tibio-tarsal segments together. Legs long,, 

 rather slender ; ungues (fig. 2 h) with a strong bulbous base ; lateral digitules 

 spathulate and longitudinally striated ; there is also a very long median 

 dorsal spinose hair, and a shorter and finer ventral one ; its basal or proximal 

 portion resting apparently in the bulbous part of the claw. Dorsum with 

 seven rows of long spinose hairs, all of them being finely but widely serrate ; 

 some of those at the margin (fig. 2 (-) are shorter than the rest and have their 

 apices slightly dilated and serrated as in the larva of the opposite sex. Anal 

 orifice just within the posterior margin ; this is more or less circular and is 

 furnished with six long hairs, as in the Dactylopiin.e.

I am not in a position at the present moment to give any further details 

 regarding the habitat of Dr. Fulleborn's specimens, I can only add that 

 they were forwarded to me with other Coccids collected by him in German 

 East Africa. 



This remarkable species is nearly related to Sticfococcus multispinosus, 

 Newstead, but the adult female is easily distinguished from the latter by the 

 sJtoi't stout and simple spines which clothe both the dorsum and the margin, 

 and the presence also of a large marsupial pouch on the venter, which latter 

 was in some few instances found to be filled with the larvse from which the 

 diagnosis Avas drawn. The most remarkable feature of this species, however, 

 is the very extraordinary dimorphism in the larva?, the structural characters 

 of the sexes being most markedly diff'erentiated. I know of no similar 

 instance of dimorphism in the larval stages of the Goccidj*:, and I believe this 

 to be an absolutely unique instance. As will be gathered from the diagnosis 

 given above, I have described the mouthless form as that of the male, as the 

 mouth-parts in the adult of this sex are invariably ol)Solete, and furthermore
