would seem to eliminate that also. Under the circumstances, especially in 

 view of the cmious mouth of the insect, I shall consider it, for the present, 

 as new. 



My specimens are partly from Otago, partly from Canterbury. Those 

 fi-om 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 

 Eoad, Lyttelton, interspersed with another curious Coccid, feeding on 

 Muhlenheckia, a creeping-plant growing thereabouts. The difference of 

 habitat is, I think, not a little curious. 



Since wi-iting the foregoing, I have found some specimens of the male 

 of Ccelostoma, which have set at rest any doubts as to its identity. Taken 

 in conjimction 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 Monophlebidte. 



The male is somewhat large, about ^ 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 Mouophlebidse. The antennaa have 

 ten joints ; the two first short and thick, the remainder long and thui, 

 ' somewhat diminishing to the extremity ; each jomt with many long hairs, 

 but no distinct nodosities as in Leachia (Signoret). The feet are long with 

 a somewhat large trochanter ; femm-, 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 haks. Claw long and thin, one pair of digitules which are only 

 long fine hairs ; on the trochanter, as in the female, is one haii* much longer 

 than the rest. From the term " Monophlebida " there should be only one 

 nervure in the wings, but, as M. Signoret remarks, this is a doubtful 

 character ; in Ccelostoma the nervure appears to me to branch twice at 

 least. The abdomen is conjugated, and on each corrugation are many 

 short fine hairs interspersed with small circular marks ; but there is no 

 fringe as in Callvpajjpus, Guerin. The sheath of the penis has the form of 

 double oval valves ; the penis itself protrudes as in Callipappits (and in some 

 Dactylojjii) as a semi-transparent, soft, white tube several times folded, 

 covered with minute hairs pointing backwards. There is a minute halters 

 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 Ccelostoma agrees with none of the
