But here is an instance of a large number of certainly adult 

 males without the least semblance of a wing. I hatched, as 

 observed just now, fifty-two males from February to August. Of 

 these, only one, which emerged on the 26th August, was winged. 

 This particular specimen has the wings developed in the usual 

 style, and is in all respects a normal Diaspid ; all the other 

 fifty-one were absolutely apterous. I cannot look upon this as 

 a normal state of things : there is nothing in the conditions of 

 the female C. dysoxijli to lead one to expect a variation in the 

 male of so fundamental a nature. Yet, considering that mv 

 specimens were so numerous, and that they emerged at various 

 times during a period of seven months, I think the fact of 

 their apterous form is of importance. 



T append the following description of the male : — 



C. dysoxyli : Adult male bright-red in colour, of the nor- 

 mal form of Diaspiclince ; length, exclusive of abdominal spike, 

 about jV^^-' ^^6 spike is about half as long as the body. Head 

 normal; eyes, four — two dorsal, two ventral. Antennae of nine 

 joints, the first two very short, the next six subequal and as 

 long as the first two together, tlie ninth shorter and fusiform ; 

 all the joints are hairy. Feet normal, hairy, rather thick ; 

 digitules fine hairs. Wings, where present, noruial, but many 

 specimens found entirely apterous. 



The nine-jointed antennae may here be a distinguishing 

 character : I know of no other Diaspid male with less than 

 ten joints.

Trees of Pittosporam tcnuifolium, in the garden of the Club, 

 Wellington, have been this year covered with great numbers 

 of small white puparia, which at first sight might easily be 

 taken for those of some species of Chionaspis, but which prove 

 to be male puparia of F. aatelicB. Here and there a few 

 females occur, but very sparingly ; more than 90 per cent. 

 seem to be males. The twigs of the plants are quite white 

 with them.
