especially in the younger forms, with a series of black markings, often forming a 

 narrow loop-like pattern ; these markings are however rarely present in very old 

 examples. Form oblong oval, but the outline is often irregular ; narrowed in 

 front and moderately convex, but the margins broadly flattened, especially the 

 cephalic portion. Antennae (fig. 11, o) of eight segments, rarely of seven ; formula 

 of the former : 3 (2, 4, 5, 8) 1 (6, 7) ; there is a very long hair on the 2nd and 5th 

 segments, and several shorter ones on the 8th, 6th and 7th, each with a distinctly 

 stouter hair. Legs normal, though the anterior tarsi sometimes exhibit a faint, ■ 

 dorsal constriction. Anal lobes (fig. 11, c) attenuated distally, inner margin 

 longest ; apices with a few fine short hairs. Anal cleft slightly less than one-third 

 the length of the body. Stigmatic cleft (fig. U, 6) very slight, sometimes scarcely

visible ; spines three in number, rather small, the central one being about three times 

 the length of the laterals. Marginal spines (fig. 11, 6) small, generally slightly 

 curved and faintly fringed distally. There are three to four hairs of varying length 

 near the attachment of each of the antennae, and usually four rather longer and 

 stouter ones just in advance of the anal lobes. Derm cells oval and markedly 

 distinct in stained preparations, but scarcely visible in mistained specimens.

This insect is specifically identical with the examples recorded by me in this Bul- 

 letin {I.e.) as Lecanium viride, Green. At the time I called attention to the fact 

 that the specimens submitted by Mr Gowdey differed from typical L. viride in 

 having the derm cells placed more closely together, and that there was an entire 

 absence of circular wax-glands surrounding the genital orifice. I now find that
