rather brown, for L. olece is not really black) ; and, secondly, it 

 is quite common to come across a twig with individuals of 

 every shade on it, varying from dark-brown to quite a light- 

 grey. In fact, the dorsal carinas and the spots are the best 

 characters for identification. 



Lecanium patersoniae. Plate XX., figs. 5, 6. 



When describing this species in 1894 I had not the second 

 stage of the female. Having received this during the year, I 

 find that it is yellow, elliptical, flattish, with a length of about 

 Jgin., and exhibits a submarginal row of pustules, as in the 

 adult. But these pustules are different. In the adult they 

 are multilocular, containing within the limiting ring several 

 minute circular glands. In the second stage there is within 

 the ring a single circular orifice, the termination of a short 

 cylindrical tube. The figures which I give will illustrate this 

 difference. ■ 



Lecanium loDgulum, Douglas. Lecanium chirimolia, MaskelL 

 This insect has come to New Zealand. Captain Broun 

 sent me specimens on Laurus, from Northcote, near Auck- 

 land. It has evidently been imported from Fiji, between 

 which place and New Zealand there is a rapidly-growing 

 trade in fruit, &c. The species is widely distributed in 

 tropical and subtropical lands. Whether it will spread to 

 the colder parts of these Islands I do not know, but it will 

 surely be found in greenhouses, and I make no doubt will 

 establish itself in the warmer districts of the North Island. 



Lecanium minimum, Newstead, var. pinicola, var. nov. 



The type of this species is described by Mr. Newstead in 

 the Ent. Mo. Mag., 1892, p. 141 ; it occurred in England on 

 greenhouse plants, and therefore was presumably not a British 

 insect. The specimens upon which I am founding my variety 

 were sent to me by Mr. Lounsbury, from the Cape of Good 

 Hope, on Pinus ifisignis, a tree not indigenous to South Africa. 

 The insect therefore probably came originally from elsewhere. 

 The variety agrees entirely with the type in size and colour, in 

 the dorsal carina, in the antennae and feet, and in the spines 

 and hairs : it is a little more convex, but that may be ac- 

 counted for by the extreme slenderness of the pine-needles. 

 The principal difference is the absence of the " large and cir- 

 cular tessellation " on the epiderm, and this is not sufficient in 

 my opinion to raise it to specific rank. 



The larva (which was not described by Mr. Newstead) is 

 yellowish, of normal Lecanid form ; length, about -^^n. An- 

 tennae short, thick, with six confused joints, the last of which 

 bears several hairs, of which the terminal one is much longer
