OBSERVATIONS ON SCALE-INSECTS (COCCIDAE)— III. 



351 



This insect resembles Lecanium {Eukcanium) pubescens, Ehrhorn,* in having the 

 dorsum clothed with hairs, but in all other respects it is markedly distinct, the salient 

 characters in L. Jiirsutum being the strongly invaginated stigmatic clefts, the curious 

 and unusual shape of the digitules of the tarsi and the innumerable small spines and 

 hairs at the margin.

of dorsum ; b, antenna ; e, leg ; d, stigmatic cleft and spines ; e, anal 



lobes ; /, marginal spines of young adult. 



Lecanium pseudotessellatum, sp. nov. 



Fetnale, adult. Very broadly ovate or sub-circular ; margin broadly flattened ; 

 dorsum low convex. Median and sub-median carinae interrupted by lateral, radial 

 carinae ; the last-named very clearly defined and equidistant at the margins. The 

 somewhat rectangular spaces enclosed by the carinae, in old examples, with a rela- 

 tively deep and large depression, giving the dorsimi a more or less tessellated appear- 

 ance. Small detached patches of glassy secretion in the hollows of the dorsum and 

 margin. Colour variable : pale castaneous, with a clearly defined darker margin 

 and irregular blackish markings in the centre of the dorsum, or dull castaneous 

 with a darker margin ; young adults are much paler. Antennae (fig. 6, a) robast, 

 of seven segments ; the 3rd very slightly longer than the 2nd ; 6th with a rather 

 stout spine; formula: 3, 2, (5,6), (4,7), 1: Legs unusually large; tibia and tarsus 

 (fig. 6, 6) together equalling the length of the antennae ; tarsus slightly thicker 

 than the tibia ; lower digitules very robust. Anal cleft slightly less than one-fifth 

 the length of the body. Anal lobes (fig. 6, c) somewhat diamond-shaped ; base
