of the genus Orthezia. 83 



Some of these particulars are, of course, generic 

 characters, yet the species being new, and the male in 

 all the known species being rare, at least in collections, 

 I have deemed it best to mention them ; but some of the 

 characters are hardly in accordance with those ascribed 

 to Orthezia, of which the formula should be enlarged 

 accordingly. 



The exuviated skin of the nymph or pupa of the male 

 (fig. 6), ruptured in front by the exit of the perfect insect, 

 is_ a transparent mask of the imago, except as to the 

 wmgs, caudal set^, and antennae (of seven joints only) ; 

 it IS also of great interest in showing, unexpectedly, two 

 claws at the end of all the monomerous tarsi, instead of 

 the single one in the larva and imago. I cannot find 

 that the pupa has been noticed in any species of this 

 genus, the reason being, probably, that it is incon- 

 spicuous and secluded, and that the duration of existence 

 in the pupa-state is very short. 



The young black larvae which came out of the maternal 

 marsupium, as before stated, still remain between the 

 glasses; I apprehend they had soon died, and, being 

 loose, have become somewhat damaged by shaking about 

 during their travel to me, but there yet remain on the 

 anterior part of their bodies some distinct bud-like 

 lamellae. 



M. Lichtenstein, however, having written, "All larvffi, 

 naale and female, are born entirely bare, and the secre- 

 tion comes only after some days," I communicated this 

 to the late Mr. G. Norman, who was then paying great 

 attention to 0. urticm and 0. cataphracta, at Pitlochry, 

 and he replied :— " As to the larvae being quite free from 

 the waxy covering on being hatched, I much doubt it. 

 I did not see the actual hatching-out, but I saw the larv£e 

 when they would scarcely have been more than a few 

 hours, or perhaps a day, old, and they certainly were 

 then not naked, but covered with the lamination which 

 showed the pattern quite distinctly ; they were then not 

 larger than small grains of sand, — decidedly smaller 

 than the eggs themselves." In proof of his statement 

 he sent a larva of 0. 2irticcs, — sb perfect miniature of a 

 full-grown larva,— and the egg-shell out of which it had 

 come, and the insect was not longer than the shell.
