MaskELL.—On New Zealand Coccide. 297 
would seem to eliminate that also. Under the circumstances, especially in 
view of the curious mouth of the insect, I shall consider it, for the present, 
as new. 
My specimens are partly from Otago, partly from Canterbury. Those 
from Otago were given to me by Professor Hutton, who informs me that 
the insect is found there on the bark of large trees. Those from Canter- 
bury I found buried in the ground and in the chinks of rocks, by the Sumner 
Road, Lyttelton, interspersed with another curious Coccid, feeding on 
Muhlenbeckia, a creeping-plant growing thereabouts. The difference of 
habitat is, I think, not a little curious. 
Since writing the foregoing, I have found some specimens of the male 
of Calostoma, which have set at rest any doubts as to its identity. Taken 
in conjunction with the peculiar mouth of the female, the characters of the 
` male make it impossible to consider the species otherwise than as new. It 
cannot be Monophlebus, as it wants the curiously protruding lobes or tassels 
attached to the segments of the abdomen; and it agrees with no other 
genus of the Monophlebide. 
The male is somewhat large, about 4 inch in length, and nearly $ inch 
from tip to tip of the wings when expanded; red or purplish in colour, with 
a strong red nervure along the anterior edge of the wings, which have also 
a bluish purple tinge all over. The eyes are large, prominent, and nu- 
merously facetted, a character of the Monophlebide. The antenne have 
ten joints; the two first short and thick, the remainder long and thin, 
somewhat diminishing to the extremity ; each joint with many long hairs, 
but no distinct nodosities as in Leachia (Signoret). The feet are long with 
a somewhat large trochanter ; femur, tibia, and tarsus not thick, the tibia 
has a dilation at the extremity next the tarsus; both tibia and tarsus have 
a fringe, on their internal edge, of strong spines (as in the female) also 
several hairs. Claw long and thin, one pair of digitules which are only 
' long fine hairs; on the trochanter, as in the female, is one hair much longer 
than the rest. From the term ** Monophlebide” there should be only one 
nervure in the wings, but, as M. Signoret remarks, this is a doubtful 
character; in Celostoma the nervure appears to me to branch twice at 
least. The abdomen is corrugated, and on each corrugation are many 
short fine hairs interspersed with small circular marks; but there is no 
fringe as in Callipappus, Guérin. The sheath of the penis has the form of 
double oval valves ; the penis itself protrudes as in Callipappus (and in some 
Dactylopii) as a semi-transparent, soft, white tube several times folded, 
covered with minute hairs pointing backwards. There is a minute haltere 
of peculiar shape (like Porphyrophora), but, I think, without a seta. 
I have no doubt, after examination of the male together with the cha- 
racters of the female given above, that Celostoma agrees with — the
