Maskell-.— On Coccidge. 65 



Eriococcus buxi, Boyer de Fonscolombe, var. australis, 



var. nov. 



Adult females enveloped in a sac of white cotton, which 

 averages j^in. in length. The antennas have six joints, of 

 which the third is the longest. The digitules are all fine 

 hairs. 



Larva yellowish-brown, elliptical. The marginal spines 

 are very small and inconspicuous. 



Hab. In Australia, in the Botanic Gardens, Brisbane, on 

 an unnamed plant. My specimens are from Mr. Froggatt. 



I could perhaps mention a number of very minute charac- 

 ters in which this insect differs from the type which is reported 

 from Europe on Buxus sempervirens : but the most important 

 seem to be those here mentioned — the digitules of the adult 

 (which in E. buxi are widely dilated) , and the marginal spines 

 of the larva (which in E. buxi are conspicuous). For the pre- 

 sent I shall not consider these as sufficient to raise the Brisbane 

 insect to specific rank ; more especially as its food-plant may 

 not be Australian, and in any case "Botanic Gardens" are 

 localities for many exotic things. 



Section DACTYLOPIN^. 

 Genus Dactylopius. 



Dactylopius eucalypti, Maskell. N.Z. Trans., vol. xxiv., 



1891, p. 35. 



I have received specimens of this species (my first from 

 New South Wales) from Mr. Froggatt, on Eucalyptus sidero- 

 phloia, Newcastle. The adults were only few in number, but 

 correspond with the type ; the larvae were numerous, and 

 presented the characteristic feathery fringe of the species. 

 Mr. Froggatt tells me that this insect is not uncommon on 

 the same tree near Sydney, but that he has never seen more 

 than one or two on a tree : it makes a red blisterlike mark on 

 the leaf. 



Dactylopius vastator, sp. nov. Plate VI., figs. 12-16. 



Female insects covered by globular sacs of whitish or 

 yellow cotton, which are frequently aggregated in large masses 

 on the twigs. Diameter of sac about |in. 



Sac of male pupa not observed. 



Adult female dark-red or purple ; slightly elliptical or 

 subglobular ; length about T V n - \ segments inconspicuous. 

 Antennae of seven joints, of which the seventh is the longest 

 and largest, the fifth the smallest, the rest subequal : all the 

 joints bear a few hairs, which are most numerous at the ex- 

 treme tip. Feet moderately strong ; tibia about one-third 

 longer than the tarsus : there is not any long hair on the
