MaskELL.—On New Zealand Coccide. 141 
Nelson and Auckland, but no remedy has been attempted. The best autho- 
rities in America have come to the conclusion that the only cure is the de- 
struction of infected plants. Some day the people of New Zealand will have 
to find this out also, but the longer it is delayed the worse the work will be. 
Whether this pest will spread in our colder southern climate as it has in 
the warmer north remains to be seen. Our gardeners here are not in much 
dread of outdoor insects, they confine their attentions to those in green- 
houses. They may be right, still the winter even in Canterbury is not 
severe enough to kill these insects, and I know that in the Christchurch 
public gardens many trees have had to be burnt simply on account of the 
ravages of Coccide. If Icerya purchasi, as seems likely, makes, it way down 
here, I very much doubt whether gardeners will find it an easy matter to 
keep it in subjection. 
Genus Ceelostoma, mihi. 
(Trans., vol. xii, p. 294.) - 
1. Celostoma zelandicum, mihi. 
(Trans., vol. xii., p. 294: vol. xiv., p. 226.) 
The haltere of the male in this insect, which I had at first taken to 
resemble that of Porphyrophora, has, as I find, four terminal sete, and 
generally resembles that described and figured below, under my next species. 
2. Calostoma wairoense, sp. NOV. 
Figs. 45-51. 
Male insect so nearly resembling C. zelandicum in outward appearance 
that it may be very easily mistaken for it, haying a red or purplish body 
about 4 inch long, bluish wings with strong red nervures, prominent eyes 
with numerous large facets, and antenne of ten joints. The antenne (fig. 
45) are, however, more slender than in that species, and have fewer and 
finer hairs. The legs also have fewer hairs, especially on the tibia. The 
claw differs entirely, not only from C. zalandicum, but also from every 
other species known to me. Instead of having two, or four, or no digitules, 
it shows a great number of them, forming indeed a sort of brush round 
the claw (fig. 47). I have counted as many as twenty-four of these 
digitules, each of which springs from the claw itself, the tarsus not exhibit- 
ing any. All the digitules are knobbed. On the tarsus there are several 
strong spines on the inner edge. The sheath of the penis and the penis 
itself resemble those of C. zalandicum. The haltere (fig. 48) has an inflated 
sac-like body diminishing to a cylindrical tube, from the extremity of which 
spring four strong curved sete of no great length; very frequenti; y only 
three are seen. The abdomen has several segments, and each segment 
bears a number of short fine hairs springing from a minute tubercular base; 
the hairs are intermixed with numerous circular spots, as in C, zalandicum,
