40 CEROPLASTES. 



It will be seen from the foregoing that the genital 

 armature of the male is very distinct, and it may, I 

 think, be considered of generic importance. The 

 puparium, however, strongly resembles the puparia of 

 the genus Lecanium, which shows the close affinity of 

 Ceroplastes to that genus. 



CEROPLASTES CISTUDIFOEMIS (Townsend, MS.). 

 (PI. XLII, figs. 1-12.) 



Ceroplastes psidii cistndifonnis (Townsend, MS.), 

 Cockerell; Zoe, vol. iv, No. 1, April, 1893. 



External waxy test or pellicle of old adult female 

 (figs. 1, 1 a, 1 c) obconical and usually compressed at 

 the sides, giving it an ovate outline at the base ; com- 

 paratively smooth, and evenly rounded from the apex 

 downwards towards the lateral white " nuclei " or 

 appendages, which are situate in deep depressions ; 

 marginal and dorsal plates absent or but very faintly 

 indicated; apical dorsal nucleus infrequently sur- 

 rounded with dull crimson and a patch of grey, 

 following which is a zone of greyish-brown with 

 radiating lines of the same colour extending into a 

 broad bluish-grey zone, which also extends downwards 

 along the elevated portions to the margins ; marginal 

 depressions broadly greyish-brown ; margin white or 

 greyish. Cabinet specimens change to a uniform 

 purplish-black with a slightly farinose surface. 



Long, 5-8 mm.; wide, 3'75-5 mm.; high, 4-6 mm. 



Old adult female forming a hollow hemisphere after 

 parturition; dermis semi-transparent, and there is no 

 horn-like projection at the anal extremity, as in some 

 species. Antennge (fig. 3) of eight joints, the second, 

 third, fourth, and fifth being longest and almost equal 

 in length; formula* (3, 4) (2, 5) 1 (6, 7, 8). Legs 

 (fig. 2) rather strong ; digitules to claw (fig. 2 a) dilated 



* I have only been successfiil in mounting one antenna, and cannot 

 therefore say if there be any marked variation in the antennal joints.
