agglomerated, especially at the tip, ^vhe^e they fonn almost a 

 patch; " and the vein is straight : whereas the dark patches 

 in A. sacchari form distinct transverse bands, leaving the tip 

 of the wing white, and the vein is conspicuously angular. 

 Signoret's description of the wings of A. bergii — " spotted with 

 black throughout the whole length " — means indeed something 

 quite different from the bands of A. sacchari; and on the whole 

 I shall leave the Fijian insect as distinct, although probably the 

 sugar-cane of Fiji may have been imported to that country from 

 Mauritius originally, and in that case may ha^•e taken its 

 Aleurode with it. 



Aleurodes papillifer, sp. nov. Plate XIII. , figs. 11-17. 



Adult insect very light yellow ; length about Tnyin. Eyes 

 red, distinctly divided, the facetted portions elongated and 

 scarcely touching ; ocellus just above each eye. Head and 

 prothorax bent distinctly downwards. Antennae slender, with 

 seven joints ; the first two short, thick, and smooth, the rest 

 slender and numerously ringed ; the third joint is the longest ; 

 the last bears two minute spines at the tip. Feet normal. 

 Wings white, immaculate ; on the margins many short fine 

 hairs. Last segment of the abdomen rather long ; cornicle 

 normal. 



Pupa yellow, rather thin ; irregularly elliptical ; length 

 about ^Viii- ' surrounded by a long, white, thin, close fringe 

 of waxy secretion. Abdominal orifice elongate. On the 

 dorsal surface are twenty short, thick, conical papillao, from 

 which spring thiekish waxy tubes ; twelve of these are on the 

 edge, the other eight arranged in two longitudinal dorsal 

 series, four being near the cephalic extremity, and foui' on the 

 abdominal region. Abdominal segments indistinct. 



Hab. In New Zealand, on Pittospomm eiujeniou/es, Genio- 

 stoma ligustrifolinm, and other trees ; sometimes found in 

 countless thousands hovering about the branches. 



Two European insects, A. lonicerce, Walker, and A. ritbi, 

 Sign., exhibit on the dorsum of the pupa longish hairs- 

 arranged similarly to those here described ; but these hairs 

 are slender and do not spring from thick, short papillae. 

 Moreover, in both of them the forewings have distinct dark 

 patches, whereas the wing of A. pa})}! lifer is quite free from 

 marks. 



Aleurodes asplenii, sp. nov. Plate XIII., figs. 18-20. 



Adult insect light-yellow, often with a greenish tinge : 

 length about ttV"^- General form normal ; last segment of 

 abdomen rather short. Antenna) ratlier long, with seven 

 joints, of which the two first are smooth, the rest numerously 

 ringed ; the second joint is three times as long as the first ;
