Adult female (fig. 1) slightly elongate-ovate; seg- 

 mentation distinct. Antenna3 (figs. 2, 2 a) very short, 

 tapering, of six joints ; first broad and flat ; second 

 often indicated by a very narrow strip of chitin; 

 sixth longest, and furnished with three or four short 

 hairs ; all the joints are highly chitinised and widely 

 separated. Legs (fig. 3) stout, strong, and highly 

 chitinised; coxae very broad; digitules to claw and 

 tarsi simple. Mentum bimerous, but the articulation 

 is by no means pronounced, and it often appears to be 

 monomerous. Anal orifice (see fig. 1) a narrow lunular- 

 shaped slit, often difficult to trace. All the segments 

 above closely set with truncate spines (figs. 4, 4 a, 4b) 

 and irregular groups of compound spinnerets resem- 

 bling those found in the Diaspinge ; there are also a 

 few short, simple spines, irregularly placed and widely 

 separated. Ventral dermis (fig. 6) with numbers of 

 minute spinnerets and a few minute spines. At the 

 period of gestation the female is either completely 

 covered or rests upon a thick white cottony material, 

 and is of a dark crimson colour. 



Long, 2-2 '75 mm.

 but in other respects it scarcely differs. 



Male (fig. 7) dark crimson, with two extremely 

 long, slender, white caudal filaments, and the body is 

 slightly farinose or mealy. Antennae (fig. 8, fourth 

 and fifth joint) of ten joints, of which the first is the 

 shortest ; all the joints with several large tuberculate
