Maskell.— 0;i Coccididse. 35 



ring with six hairs. Epidermis bearing large numbers of 

 simple circular spinnerets and fine hairs. 



Larva not observed. 



Male pupa brown, enclosed in a sac of white cotton smaller 

 and more elongated than that of the female. Adult male 

 unknown. 



Hah. In Australia, on Acacia armata and Acacia decur- 

 rens. 



Another of Mr. Crawford's species, to which he originally 

 attached the name of Erium glohosum. My specimens on 

 Acacia decurrens were sent by Mr. French. 



Dactylopius eucalypti, sp. nov. Crawford Coll. Plate VII., 



figs. 9-13. 



Adult females congregated in masses of white cotton be- 

 tween the sheets of bark of the plant ; form subglobular, 

 segmented ; colour red or yellowish - brown : length about 

 Jjin. Antennae of seven joints, of which the third is the 

 longest, and the seventh is scarcely longer than the sixth. 

 Feet with a rather short tarsus, not more than a third of the 

 length of the tibia, and rather thick ; all the digitules are long 

 fine hairs ; on the trochanter are two rather strong hairs. 

 Anal tubercles scarcely visible ; anogenital ring compound, 

 with many hairs (in some specimens apparently twenty). 

 Mentum doubtfully dimerous. Epidermis bearing many small 

 circular spinnerets, and on the cephalic region a number of 

 rather long spmy hairs. 



Larva yellowish-brown, congregated sometimes in very 

 great numbers on the bark, mingled with thin white cotton or 

 meal ; form subcircular, slightly elongated and tapering some- 

 what posteriorly; distinctly segmented, flattish, active: length 

 about g^n. Antennse of five subequal joints, the third a 

 little the longest; on the last joint there is an excessively long 

 hair. Feet rather thick : the tibia is shorter than the tarsus. 

 All round the margin is a ro.w of conspicuous feather-like 

 pointed processes, forming a fringe. Anal tubercles small, se- 

 tiferous. 



Male pupjB congregated in sacs of white loose cotton, mixed 

 with those of the females and larvae, or sometimes in masses 

 by themselves. 



Adult male reddish-brown ; abdomen rather slender: length 

 of body about ^f^in. Wings hyaline, slightly iridescent. 

 Antennae of ten joints. Feet long and slender, with a very 

 short tarsus. Abdominal spike short, conical. Dorsal eyes, 

 two ; ventral eyes, two : ocelli, two. 



Hab. In Australia, on bark of Eiicalyptus amygdalina. 



This is one of the late Mr. Crawford's species. It appears 

 to be clearly distinct, and in some of its characters abnormal.
