Maseell. — On Coccidae. 297 



California, China, Australia, South Africa, and other countries, 

 and has now reached New Zealand. Specimens have been 

 sent to me by Captain Broun, on olive, from Whangarei. It 

 is by no means particular as to either locality or food-plant. 



Aspidiotus articulatus, Morgan, var. celastri, var. no v. 



Plate XVIII., fig. 1. 



Puparium of female larger than that of the type ; and the 

 ■colours of the pellicles and of the secreted portion are ratlier 

 brownish than greyish. 



The adult female is also larger than the type, reaching a 

 length of x\in. The abdominal lobes and scaly hairs, the 

 •deep groove separating the thorax from the abdomen, and the 

 prominent small subconical process on each side of the 

 thorax above the groove are identical with those of the type. 

 But there are four groups of spinnerets, as against two in 

 A, articulahis ; the upper groups have 6 to 8 orifices, the 

 lower (which are long and narrow) 8 to 12. 



Uah. At the Cape of Good Hope, on Celastrus laurinus. 

 My specimens were sent by Mr. Lounsbury on a plant in the 

 Museum herbarium at Capetown, collected in 1825. 



Mr. Morgan, in his description (Ent. Mo. Mag., Aug., 1889, 

 p. 352), does not make any mention of the small conical pro- 

 cess or spine on the margin of the thorax of this species. 

 This, however, appears to me to be a sufficiently important 

 character, and its presence in the insect now under review is 

 a strong incentive to me to make it only a var. of A. articu- 

 lahis, in spite of the greater number of spinneret groups. 

 There is something analogous to this spine in Diaspis bois- 

 duvalii, Signoret, but there it is much less conical. 



In the Ent. Mo. Mag., Sept., 1896, p. 199, Mr. E. E. 

 Creen describes two new insects allied to A. articulatus, with 

 figures, but he neither mentions nor delineates any marginal 

 cones on the thorax. 



Aspidiotus ficus (Kiley), Comstock. 



This insect occurs in Japan, on Quercus cuspidata, and pro- 

 bably on several other plants. I have had specimens sent by 

 Mr. Koebele during the year. 



Aspidiotus destructor, Signoret. Plate XVIII., fig. 2. 



Mr. Koebele sent me some leaves of Celtis occidcntalis 

 from Hongkong, on which were several insects which I can- 

 not attach to any species except A. destructor, for the reason 

 that the two median lobes are shorter and smaller than the 

 next pair outside them. As the species is probably widely 

 distributed in the tropics (at least, in the Oriental region), I 

 give a magnified figure of the extremity to exhibit this cha-
