amples examined, and I am very greatly obliged to bim for tbe pains 

 be bas taken to obtain tbem, all tbe more tbat circnmstances bave 

 unfortnnately precluded me from attempting tbe work ; and I am also 

 greatly indebted to bim for transferring bis figures to tbe plate. 



LeCANIUM BECI0NIJ3, 11. Sp. 

 ? adult. Scale jet-black, under a high power seen to be covered with con- 

 tiguous, minute, oval, yellowish dots, shining, smooth, convex, broad-ovate, or in 

 some instances oval, being more rounded anteriorly, sides straighter, and disc 

 humped ; the margin slightly extended, recurved, and finely punctured (up to 

 the penultimate state the colour is brown) ; anal cleft closed, the point above it very 

 small, yellowish. Antennae of seven joints (fig. 4) ; the 1st broadest, short; 2nd 

 one-third longer ; 3rd twice the length of the 2nd ; 4th one-third longer than the 

 3rd, with a constriction simulating a joint at two-thirds of the length, whence a long 

 hair projects ; 5th and 6th equal, each less than half as long as the 4th, and with 

 one hair; 7th about as long as the 3rd, pointed, sides gradate, with several hairs. 

 Legs (fig. 4a) long ; trochanter with one long hair ; tarsi three-fourths the length 

 of the tibiae ; digitules normal. Length, 3—4 mm. 



Tbe oval examples, especially, very mucb resemble L. nigrum, but, 

 as will be seen by reference to tbe description and figure, Ent. Mo. 

 Mag., ii, 11. s., p. 95, fig. i, tbere is great difference in the proportion 

 of tbe joints of tbe antennae, wbicb character was noticed in all tbo 

 specimens of eacb species tbat were examined ; in tbe present species 

 also tbere are but seven joints instead of eigbt. 



Heceived in October, 1891, on tbe stems and under-side of leaves 

 of a Begonia, from tbe Botanic Garden at George Town, Demerara.

 December, 1891. 



Postscript, July, 1892. — Altbougb characters derivable from tbe 

 larva are wanting, I am now inclined to believe that those of tbe adult 

 state, in both sexes, indicate tbat this insect belongs to the Family 

 Lecanodinspida, Targ.-Tozzetti .
