GENUS CRYPTOCOCCUS (Douglas). 

 (PL LXX, figs. 1-10.) 



Adult females stationary, living within a felted 

 ovisac. Antennas rudimentary. Posterior pair of legs 

 rudimentary ; anterior and intermediate pair absent. 

 Anal lobes normal. 



Larva with anal orifice as in the adult female. 

 Antennas of five joints. 



This, at present, is also a monotypic genus, and it is 

 one of the most clearly defined of all the Dactylopiinas. 

 The distinguishing features of the female are the 

 extremely minute antennas (figs. 2, 2 a), the equally 

 small tuberculate processes which are mere vestiges of 

 the posterior legs (figs. 3, 3 a), and the abnormal 

 number of spines or hairs on the anal orifice. The 

 salient characters of the larva (fig. 7) are the anoma-
