Maskell. — On Coccidae. 57 



Feet long and slender ; digitules fine hairs. Margin of body 

 very minutely serrated. 



Adult male unknown. 



Hab. In Australia, on Banksia serrata. Mr. Froggatt 

 sent me eight adults and a few others from Manly, near 

 Sydney. He informed me that the insect seems to be very 

 rare ; but hopes to be able at a future time to procure more. 



I have no hesitation in separating this species and genus 

 from other Lecanio-diaspida, the characters of the secreting 

 pores and therefore of the secreted test being so different. If 

 it could possibly be placed in a known genus, I suppose that 

 would be Ceroplastes ; yet I know of no Ceroplastes where 

 the test is so loosely constructed as in G. banksia. Of course 

 the fact of the insect being only partially covered by the waxy 

 threads is not a sufficient generic character : it will amply 

 suffice for specific distinction, because it depends upon the 

 absence of pores in the median dorsal region. The antenna 

 of the larva is somewhat unusual in its length and slender- 

 ness. 



Section LECANIMJ. 

 Genus Lecanium. 

 Lecanium patersonise, sp. nov. Plate V., figs. 1-3. 



Adult female reddish-brown, sometimes yellowish -brown ; 

 flat, elliptical with nearly parallel sides ; length, about Jin. 

 There is a distinct longitudinal median carina, and frequently 

 two transverse carinas less distinct. The dorsum is sometimes 

 naked, but usually covered with very thin white waxy meal, 

 scattered in minute patches. Antennae of seven joints, of 

 which the third is the longest, the second next, the rest 

 shorter and subequal : the last bears several hairs. Feet 

 rather slender, of normal form ; digitules slender. The 

 margin of the body bears numerous short hairs. On the 

 dorsal epidermis there is seen a row, all round the body, 

 a short distance within the margin, of oval or circular pus- 

 tules, not always at regular distances, but sometimes as in 

 pairs : there seem to be on an average from thirty-six to forty 

 of these on each side. There are also, scattered over the 

 dorsum, great numbers of smaller oval spots. The pustules 

 are by no means distinctly visible, and both they and the 

 small spots are scarcely to be made out until the insect is 

 rendered more or less transparent. 



Second stage of female, and larva, not observed. 



The male pupa is covered by a test of the usual elongated- 

 elliptical form, composed of segments of thin white wax, the 

 posterior segment hinged for egress. Length of the test about 

 •J^in. These male pupas seem to be more numerous than the 

 females.
