1. Dactylopius alpinus, sp. nov. 
Figs. 39, 40. 
Adult female dark purple in colour, the body thick and fat, inactive, 
enclosed in a mass of white closely felted cotton. When immersed in 
alcohol it produces a rich red tint. Length sometimes as much as + inch. 
The internal substance is very oily. The body is normally segmented ; 
anal tubercles inconspicuous. Anal ring large, with six hairs. Antenne 
normal of the genus, with eight joints (fig. 89). The feet are normal; the 
two upper digitules are long fine hairs, the lower pair are somewhat 
broader. Mentum di-merous. All over the body there are a number of 
tubular projecting spinnerets, and many others circular; and on the three 
posterior segments are three rows of large conical spines, similar to those 
of Rhizococcus. Although the anal tubercles are not as prominent as in 
some of the Dactylopii, they are somewhat thick, with broad bases. 
‘ Young insect dark brown in colour, of generally normal form, about 4; 
inch in length. Antenne (fig. 40) of six joints. Feet normal. Anal tuber- 
cles thick and broad, and rather more prominent than in the adult. There 
are a few small spines on the body. 
In the second stage the insect generally resembles the young larva, but 
is larger, and the body is covered with a great number of small circular 
spinnerets intermixed with others which have a bulbous base and fine hair- 
like tubes. Anal tubercles inconspicuous, bearing the usual spines. A few 
conical spines appear on the posterior segments. Antenne of six joints. 
I have not seen the male. 
.On a species of Veronica, sent me by Mr. J. D. Enys, from the upper 
valley of the Waimakariri, in the Southern Alps, near the glaciers. 
The large conical spines, or spinnerets, on the posterior segments, dis- 
tinguish this species, besides its size and very deep purple colour producing 
a rich tintin alcohol. The thick sac of white cotton in which it envelopes 
itself may probably be also an important character: in no stage, I think, is 
it like the ordinary ** mealy bug," the type of Dactylopius. 
2. Dactylopius calceolarie, mihi. 
(Trans., vol. xi., p. 218.) 
Since first describing this insect I have received specimens from the 
forests of Stewart Island, in the extreme South of New Zealand, on a 
native grass, Danthonia, and on a leaf of Phormium. As Stewart Island 
is almost destitute of cultivation, and is certainly the last part of the colony 
where one would expect to find in the forests a new importation from other 
countries, I take it that D. calceolaria is undoubtedly indigenous.
