Male puparium unknown. 



Adult female dark-brown, of normal elongated form ; 

 length, about T Vin. Abdomen terminating, as in the type, 

 with two largish median lobes, above which are two club- 

 shaped organs ; no groups of spinnerets ; several strong 

 marginal spines, which are also on the anterior abdominal 

 segments. 



Male unknown. 



Hab. In Sandwich Islands, on " bark of shade-trees," 

 not named, at Kona. My specimens are from Mr. Koebele. 



The difference between this and Comstock's American 

 species (in conservatories at Washington) seems to consist 

 only in the fact that the Sandwich Island form does not 

 burrow, but lies exposed on the bark. The anatomical 

 characters seem identical. 



Chionaspis dysoxyli, Maskell. N.Z. Trans., vol. xvii., 1884, 



p. 22. 



This insect occurs on Holier ia angustifolia on the hills 

 above the Town of Lyttelton, in this country. I found many 

 specimens there in the autumn of this year, when searching 

 for Eriococcus hoherice, which I failed to find. The pu- 

 paria of the Chionaspis are narrower than those of the original 

 type, as indeed is only natural, being on narrow twigs and 

 leaves instead of on the broad ones of Dysoxylon ; but I can 

 detect no difference in the insect itself. These are the first 

 specimens of the species reported from the Middle Island. 



Chionaspis xerotidis, sp. nov. Plate II., figs. 6, 7. 



Female puparium whitish, flatfish, pyriform ; length about 

 -|in. Pellicles yellow, comparatively small. The form of the 

 puparium is frequently obscured by masses of dirt and mud. 



Male puparium whitish, elongated, narrow, carinated. 

 Length about -g^in. 



Adult female yellow, elongated ; length about ^in. The 

 abdomen ends with a small median depression, the sides of 

 which form small lobes, and at each side there are four equally 

 small rounded lobes with three spines, and one spine a short 

 distance along the margin. All the abdominal and thoracic 

 segments bear marginal groups of rather strong spines. Five 

 groups of spinnerets : upper group with 8-10 orifices ; upper 

 laterals about 20 ; lower laterals about 33 : but it is not easy 

 to separate the lateral groups, and the whole arrangement is 

 very nearly an arch. There are a great many large oval pores 

 marking the abdominal segments. 



Adult male unknown. 



Hab. In Australia, on an aquatic plant of the sedge family 

 — Xerotcs longifolia. My specimens were sent by Mr. Frog-
