Maskell. — On Coccidae. 59 



Larva yellowish-red, elliptical, active ; length ahout 

 Jg-iu. The median dorsal region usually exhibits a raised 

 longitudinal ridge, not divided into distinct tubercles. The 

 abdominal cleft, lobes, and setae are normal. Antennas rather 

 thick, and very long, almost half as long as the whole body ; 

 they have six irregular joints. Feet also long, with thick 

 tibia and tarsus. 



Adult male and male pupa unknown. 



Hab. In Australia, on Dillwynia juniper ina. Mr. Froggatt 

 sent me specimens from Bankstown, near Sydney. 



This insect approaches very closely to L. scrobiculatum, 

 Mask. (1892) ; the differences are the absence of the feet in 

 the adult, the colour, and the greasy appearance. The two 

 last are of small importance, and if it were not for the first I 

 should consider the insect as merely a variety. I have already 

 mentioned that L. scrobiculatum has dorsal tubercles. Full 

 certainty as to the position of L. pingue may perhaps be 

 attained when the larva of L. scrobiculatum shall have been 

 found. 



Lecanium armeniacum, Craw. 



I do not know where any description of this form is to be 

 found. But Mr. Ehrhorn has sent me specimens from Cali- 

 fornia, and tells me that it is there a pest on the apricots, 

 plums, and peaches. From these specimens I believe it to be 

 merely a rather smaller form of L. persica, Sign., if indeed it 

 can lay any claim to be considered even a variety. The habit 

 of erecting new species without proper description and com- 

 parison is a pernicious one ; still more so if mere colour or 

 food-plant be taken as the basis. 



Lecanium tessellatum, Signoret. 



This occurs at Adelaide, on Palms in hothouses. My 

 specimens are from Mr. Quinn, who tells me that it attacks 

 scarcely any other plants in that locality. 



Lecanium hemispheericum, Targioni-Tozzetti. 



This insect occurs plentifully in hothouses in Adelaide on 

 ErantJicmum variegatum. I have had specimens from Mr. 

 Quinn. 



Genus Pulvinaria. 



Pulvinaria mammeae, sp. nov. Plate V., figs. 8-11. 



Adult female reddish-brown, covered with thin greyish- 

 white meal : the colour fades to yellowish in extreme age. 

 The form before gestation is flattish, regularly elliptical, with 

 sometimes a faintly-raised longitudinal dorsal ridge. The 

 length at this period is about Jin. At gestation it shrivels
