mens have antennas of seven joints, but otherwise agree with 

 the type, and the antennal difference is not important. The 

 buff-coloured meal covering the dorsum readily distinguishes 

 the species at first sight. 



Dactylopius ericicola, sp. nov. Plate XV., figs. 10, 11. 



Adult female varying in colour from dark-brown to red ; 

 subglobular, with the ventral surface concave at gestation ; 

 accompanied, but not covered, by grey or dirty- white cotton, 

 which is frequently aggregated in masses ; length of insect 

 about oV 11 - Antennas of seven joints, all subequal except the 

 last, which is as long as any two others. Feet moderate ; 

 digitules fine hairs. Anal tubercles very minute and incon- 

 spicuous ; anogenital ring with six hairs. Epidermis very 

 minutely wrinkled, and bearing some circular spinneret-orifices 

 and some conical spines. 



Female of the second stage not observed. 



Larva brown, rather elongated and slender ; length about 

 •Jgin. Antennas rather thick, with six joints, subequal except 

 the last, which is longer than any two others. Feet also thick. 

 Mentum dimerous. 



Adult male dark reddish-brown ; length about ^in. An- 

 tennas of ten joints, all rather thick and subequal. Feet rather 

 long and slender. Abdominal spike very short ; setas very 

 long. 



There is usually much black fungus accompanying this 

 insect, and it is also much infested by a minute yellow 

 hymenopterous parasite. 



Hah. In Australia, on Erica autumnalis. My specimens 

 are from Mr. French. 



I am under the impression that Erica autumnalis is not a 

 native of Australia, and consequently the insect here described 

 may not be Australian, but perhaps imported there from the 

 Cape of Good Hope. I cannot identify it with any known 

 species, though it comes nearest to D. qlobosus, Mask., from 

 which it differs by not being covered by its cotton, and in the 

 characters of the epidermis. 



Dactylopius nipse, sp. nov. Plate XV., figs. 12-15. 



Adult female dark-red in colour, flatfish, subcircular ; 

 diameter about i^in. exclusive of the cotton ; excreting on 

 the dorsum whitish or yellowish cottony meal, and all round 

 the margin subcylindrical tassels of yellowish cotton, which 

 are sometimes equally long all round, sometimes longer pos- 

 teriorly ; the dorsal meal is often arranged in rows in little 

 granular masses. Antennas of either seven or eight joints, of 

 which the last is much the longest, the third and the penulti-
