reversing the European arrangement — or else the two species 

 are identical. The latter alternative is that which induced me 

 to report L. hcsperidum alone in 1878 and 1887 in New Zea- 

 land, and which seems to me still to be correct. 



Lecanium tessellation, Signoret. Sign., Essai, p. 231. 



Plate XIII., fig. 1. 



This insect, which, from its flatness and viviparous habit, 

 belongs to Signoret's first series of the genus, is characterized 

 especially by " a marquetry pattern on the epidermis, in which 

 each separate section is unlike the one next to it, but quite 

 similar to the similarly-situated section on the opposite side." 

 Each side, therefore, of the body seems quite irregularly marked, 

 but the two sides are symmetrical. The insect is reddish- 

 brown, flat, rather acuminate anteriorly and broadly rounded 

 posteriorly. The markings are not to be clearly made out 

 until after treatment with reagents. Length about -Jin. 



Hab. In Australia, on Lauras nobilis, Sydney. My speci- 

 mens are from Mr. Koebele. Signoret reports the insect as on 

 palms in hothouses in Europe. 



Lecanium acuminatum, Signoret. Sign., Essai, p. 227. 



Plate XIIL, figs. 2, 3. 



Adult female yellowish-brown, flat, acuminate at the 

 cephalic extremity and very broadly rounded posteriorly. 

 Length about -|in. Antennae of seven joints, of which the 

 fourth is the longest, the fifth and sixth the shortest. Tarsus 

 about half as long as the tibia. The epidermis bears a large 

 number of circular marks, each with a central clear space. 



Female of second stage broadly elliptical, flat, yellowish ; 

 length about ^in. Antenna? of six joints. 



Larva yellowish-brown, flat, broadly elliptical; length 

 about -j^in. 



Male unknown. 



Hab. In the Sandwich Islands, on guava (Psidium sp.). 

 Sent by Mr. Koebele. 



I do not doubt my identification of this species. Signoret 

 (whose specimens were on hothouse orchids in Paris) does not 

 mention the dermal markings.

Lecanium anthurii, Boisduval. Signoret, Essai, p. 265. 



I have received from Mr. French specimens of an insect on 

 Asparagus sp., Melbourne, which appear to me to belong to 

 this species, which belongs to Signoret's fourth series, being 

 very convex, with a dermal pattern of oval marks, not con- 

 joined, and with a median clear space in each. The colour is 

 brown. The original species occurred in Europe on a hot- 

 house orchid.
