the margins. The insect at first fills the test, but shrivels at 

 gestation. 



Female of the second stage not observed. 



Larva brown, elongated, elliptical, slightly tapering pos- 

 teriorly ; the abdomen is conspicuously segmented, and ends 

 in two conspicuous anal tubercles bearing long setae. An- 

 tennae of six joints, of which the third is the longest, the last 

 three short and confused : indeed, I am not sure that there 

 may not be seven joints. Feet offering no distinctive charac- 

 ter. The whole dorsum bears transverse rows of large figure- 

 of-eight spinnerets. A larva extracted from the body of the 

 mother is very soft and whitish, with a length of about ^oin. ; 

 after emergence it becomes darker, and attains -gxjin. 



Adult male unknown. 



Hab. In Fiji. My specimens were sent to me by Mr. E. L. . 

 Holmes, of Bua, on pieces of bark of some plant of which he 

 did not give me the name. 



This is certainly an elegant little species, and from its leaf- 

 like processes the name which I have attached to it seems to 

 be appropriate. I think it a good instance of the absurdity of 

 including such genera as PlancJionia amongst the " Lecanio- 

 diaspidcB," as there is not the slightest Lecanid or Diaspid 

 character about it. 



Planchonia fimbriata, Fonscolombe. 



Boyer de Fonscolombe, in 1834 (Ann. de la Soc. Eut. de 

 France), described, under the name " Coccus fimhriatus," an 

 insect which Signoret,in 1868, attached correctly to the genus 

 PlancJionia. Since then several species of that genus have been 

 reported from different countries and on diiferent plants. My 

 studies of actual specimens, and of the published descriptions 

 of authors, lead me to the conclusion that, wdth the exception 

 •of P. bryoides, just described (which is markedly distinct), they 

 all really constitute one species, with perhaps some varieties, 

 differing principally in the external colours. The synonymy 

 of the species will therefore be as follows, giving Fonscolombe 

 .the priority as regards the specific name : — 



P. fimbriata, Fonscol., 1834 = P. (Asterolecanium) querci- 



cola, Bouche, 1851 (perhaps) : = P. arabidis, Lichten- 



stein, 1876 = P. hedera, Licht., 1880. Test yellow, 



fringes white or pinkish. 



P. fimbriata, var. epacridis, Maskell, 1881. Test partly 



green, partly yellow; fringes white. 

 P. fimbriata, var. styphelice, Maskell, 1891. Test whitish, 



or with a greenish tinge ; fringes white or pink. 

 P. fimbriata, var. pustulans, Cockerell, 1893 = P. oncidii, 

 Cockerell, 1893. Test yellow or greenish- yellow ; fringes 

 pink or whitish-pink.
