Maskell. — On Coccidse. 399 



Eriococcus buxi, Fonsc, var australis, Maskell. Trans. 



N.Z. Inst., vol xxvii., p. 65. 



I have received from Mr. Froggatt some specimens which 

 I shall attach to this species, the principal difference from the 

 type being apparently only the size. The female sac is only 

 about ^V^- long, and the male sac still smaller. There seem 

 to be no other distinguishing characters. 



Hah. In Australia, on Trachyviene hillardieri. Specimens 

 from Sydney. 



Eriococcus paradoxus, Maskell. Trans. Eov. Sec. South 



Australia, 1887-88, p. lOi. 



Specimens received from Mr. G. Quinn, of Adelaide, on 

 Piitosporum bicolor, belong to this species. Mr. Quinn says, 

 " This is most destructive on this genus, and the gardener at 

 Government House has burnt a number of the shrubs in con- 

 sequence, and cut out large quantities of branches of the 

 others." My original specimens were on Pittosjjorum undu- 

 latum. 



Genus Dactylopius. - 



Dactylopius adonidum, Linn. 



In the " Annals and Magazine of Natural History," August, 

 1895, I published some remarks on the genus Dactylopius, 

 and mentioned an outbreak of D. adonidum in the Hatt 

 Valley, near Wellington. I have received specimens from Mr. 

 Froggatt, of Sydney, New South Wales, on Acacia linifolia, 

 which I also attach to this species, although in colour they 

 are browner, or redder, than usual. Probably there is no 

 character which serves for differentiating D. adonidum from 

 others of the genus better than the sequence of the antennal 

 joints. The insect is apparently omnivorous and cosmo- 

 politan. 



Dactylopius longifilis, Comstock. Eep. Entom. U.S. Dept. 



Agric, 1880, p. 344. 



This insect occurs on Croton, at Calcutta, and in all pro- 

 bability elsewhere in India. Specimens were sent to me by 

 Dr. Alcock, of the Indian Museum. 



Genus Lachnodius, gen. nov. 

 As the study of Coccids progresses forms are constantly 

 being found which in some character or characters depart 

 from the generic types hitherto known. Sometimes the 

 variations ai'e but slight and unimportant, and in such cases 

 it has been my rule to leave the species in a known genus 

 without proposing or suggesting its future removal therefrom. 

 Sometimes the abnormal characters have seemed to me funda- 

 mental, and I have established new genera on single species;
