SCALE INSECTS (" COCCIDiE ") OF AUSTRALIA. 99 



about one-third the length of the tibia ; the tibia rather less than three- 

 quarter of the length of femur and trochanter together. Length of coccid, 

 2-50 mm." 



The authors give a sketch of the different forms of the antennse, and state 

 that this species is allied to Dactylopius glohosiis (Mask.), but differs in the 

 test, being much slighter in the structure of the legs and in the smaller size 

 of the adult insect.

This is the Bromelia or pineapple scale common in many parts of tlie 

 world on those plants, and also recorded upon mulberry, canna, and hibiscus. 

 Recorded from India, Africa, North and South America, and Grafton, New 

 South Wales. 



The adult female coccids are red, ellipitcal, slightly convex, measuring 

 about A- of an inch in length, coated with a white floury secretion, through 

 which the segmental lines can be traced ; the fringe of more fiocculent matter 

 irregular and slight round the front and side margins, but on the anal segment 

 produced into a row of about eight white tails of equal length. 



Antennae, as described by Maskell, eight-jointed, the last longest. Legs 

 long, with nobbed digitules. Epidermis with circular spinnerets and spiny 

 hairs. Anal tubercles very small with long setae. Anal ring compound, 

 with eight long hairs. 



The coccids crawl all over the base of the pineapple fruits, and are massed 

 together in the inequalities on its surface.

DactyhyiKs candidus, n.sp. , 

 This is a common coccid upon the foliage of the black wattle {Acacia 

 decurrens), growing. in the coastal districts in the neighbourhood of Sydney. 

 The insects attack the young branchlets, twisting and aborting them, while 

 the adult female works along the under-surface of the midrib of the leaves,, 

 covering them with woolly white secretion, upon which she lays her eggs. In 

 the earlier stages of development they move about among the branchlets, 

 often so abundantly that the whole bush is covered with white filaments. 

 This species is allied to Maskell's Dactylopivs acacice, but differs from it in 

 not forming masses of woolly secretion, but living free upon the surface of a 

 flattened mass; also in ttie structure of the anteniife and anal tubercles.
