and abdominal segments are rather plainly visible. Surface 

 of test striated, and there are four patches of brown radiating 

 from the pupa in the middle towards the edges ; in these 

 patches are several circular, small, tubercular marks. The 

 edge of the test is dark-brown, seemingly containing a number 

 of minute tubercles ; but there is no sign of a fringe. Length 

 of test about yV^^- 



Hab. In New Zealand, on 3Ielicytus ramifloriis. 



This is a large and, from its rich colour, a handsome species 

 in the pupa stage. It seems to be nearest to A. proletella, 

 Linn., which has not, however, the radiating patches with 

 small tubercles on the dorsum of the pupa. Misled by the 

 apparent similarity to a Lecanid insect, I included this species, 

 in 1878, amongst Coccids. 



Aleurodes fagi, sp. nov. Plate XIII., figs. 25, 26. 



Pupa dull-yellow ; elliptical ; length about ^y^jin. ; rather 

 thick, with perpendicular sides which are slightly overlapped 

 by the dorsal disk ; enclosed insect indistinctly visible, the 

 abdominal segments rather clearly marked. Dorsum slightly 

 convex, finely striated. No fringe, but round the edge are 

 twenty-four rather strong hairs, at about equal intervals. 



Hab. In New Zealand, on Fagus menziesii. Specimens 

 sent to me by Mr. E. Kaithby, of Inangahua. 



The arrangement of the hairs, and the size of the dorsal 

 disk in this pupa as compared with the ventral surface, seem 

 to be distinguishing characters. I have not seen the adult. 



Aleurodes simplex, sp. nov. Plate XIII., fig. 27. 



Pupa very light yellow, sometimes nearly white ; elliptical, 

 very slightly convex, texture very thin ; length about Trjin. 

 Eudunentary organs scarcely to be made out. Edge rather 

 thicker than the rest, and finely striated, but there is no fringe. 

 Abdominal extremity distinctly cleft (as in the Coccid genus 

 Lecaniiim) ; abdominal orifice elongated, situated at the inner 

 end of the cleft. On the dorsal region are several hairs, which 

 do not spring from conical papillae. 



Adult unknown. 



Hab. On Pittosporum eugenioides , Coprositia lucida, and 

 several other trees in New Zealand. 



This species in the general form of the pupa resembles 

 A. rubi, Signoret, and A. fragarice, Walker, and both of these 

 have similar dorsal hairs ; but the abdominal cleft appears to 

 be distinctive. 



[In 1878 ("Trans. N.Z. Inst.," vol. xi., p. 215) I included 

 amongst Coccids two insects really Aleurodidcs, imder the 

 generic name oi Asterochiton. Ast. aureus is Aleurodes melicijtl
