uated, but there is often a median very slight dorsal elevation, 

 and the margins are finely corrugated as in the adult. 



Hah. On gooseberries, black and red currants, in New 

 Zealand, Europe, and America. My New Zealand specimens 

 were received from Mr. W. W. Smith, of Ashburton, who in- 

 forms me that the insect is common at that place in gardens. 

 This is to be regretted, as it is likely to spread with rapidity 

 and to do much damage. 



This species is closely allied toL. hemispharicum, Targioni, 

 to L. hihernaculorum, Boisduval, and to L. rugosum, Siguoret. 

 It differs from the two first in the absence of markings on the 

 skin, and from the last (which attacks peach-trees) in its 

 general smoothness, and a few other particulars. 



Lecanium frenchii, sp. nov. Plate IV., figs. 1-8. 



Adult female very dark-brown, or rich glossy black ; form 

 sub-circular, very slightly convex ; diameter about ^in. Dorsal 

 epidermis covered with numerous minute pits, and divided into 

 irregular tessellations by smooth narrow bands, of which one 

 is median and longitudinal, the others ramifying fi-om it 

 towards the margin. If the insect is macerated in potash the 

 small dorsal pit-like marks appear as oval spots ; the median 

 band is not noticeable, but the transverse ones appear like 

 cracks or slits in the body. Margin fringed with numerous 

 very small fan-like processes, attached by a very short stalk, 

 and with a short tubular canal extending from each into the 

 body ; this fringe is usually yellow. Antennte slender, with 

 eight joints. Feet very slender ; upper digitules fine knobbed 

 hairs, lower pair slightly dilated ; on the trochanter a longish 

 hair, and I think a spine on the tibia. The spiracular spines 

 are ver^ short, placed in small depressions, and not extending 

 beyond the margin ; they are somewhat club-shaped and thick. 

 The abdominal cleft is rather deep ; the lobes are triangular, 

 small, adjacent. Anogenital ring with numerous hairs. At 

 gestation the body becomes slightly hollow beneath. I think 

 the insect is oviparous : at least, empty egg-shells are to be 

 found beneath the body, and I have not seen any larvse within 

 the abdomen. 



Female of the second stage yellow or light-brown, flat, 

 elongated ; length reaching sometimes ^^va.. On the dorsum, 

 in some specimens, fragments of a white, glassy test may be 

 seen ; but there is no fringe, except the small fan-like pro- 

 cesses as in the adult, and these are not noticeable until 

 towards the end of this stage. Antennae of six joints. Feet, 

 spines, and anogenital ring as in the adult. 



Larva and male unknown : the male pupa has a white 

 waxy test. 



Hab. In Australia, on Banksia australis. My specimens
