and other tropical fruits, as well as those in the warmth of the hothouse. 

 Maskell has recorded it upon Acacia lotigifolia from specimens sent to him 

 from New South Wales under the name of D. aclonidum, under which name 

 it has usually been recorded by Australian entomologists. I have recently 

 had thistle stems covered with adults and larvae. 



Newstead says : " Adult female elongate, oval, covered with white mealy 

 wax except on the articulation of the segments, where the colour of the body 

 shows through ; fringed with white waxy appendages, the outer caudal ones 

 often longer than the whole insect. Antennae, eight-jointed ; third, fourth, 

 and eighth longest. Anal lobes faintly indicated, each with one long and 

 two minute hairs, and a ventral group of spinnerets surrounding two short 

 spines. Anal orifice with six rather long hairs. Length, 3-4 mm." 



This mealy bug can generally be recognised from the great length of the 

 two waxy woolly anal filaments, usually only slightly longer than the other 

 filaments in allied species like D. lobulatus.

Found at the base of the fronds of Macrozamia frazieri at Swan River, 

 Western Australia. 



Adult female light brownish yellow, elongate, flattened, segmented, with 

 the dorsal surface clothed with white mealy secretion. Antennae eight- 

 jointed; feet simple, spined; tubercles small; anal ring conspicuous with 

 six hairs ; dorsum clothed with many fine hairs and raised spinnerets. Length, 

 0-16 inch.

This species was described from specimens found upon the roots of a daphne 

 at Myrniong, Victoria. 



I am informed that the type is lost ; according to the author's description 

 it is so closely related to Maskell's subterranean species {Dactylopius affinis) 

 that it is very difficult to see upon what the specific differences are founded. 

 He says : " Differs in the granular character of the mealy or cottony sec- 

 retion ; is larger, and the long single projecting fringe is suflicient to separate 

 it."
