44 ENTOMOLOGICAL NEWS. [Feb., 'O2 



the tree referred to above is growing quite close to a butter 

 factory, and I myself have often seen drivers of milk carts 

 cutting switches therefrom to use instead of a whip, and on 

 the return journey cutting off the twigs and leaves, leaving 

 them scattered along the road, the switch, no doubt, ultimately 

 reaching the homestead. 



The range of distribution of hcdcns is evidently extending. 

 Mr. G. B. King reports it from Bermuda (Psyche, p. 350, 

 April, 1899) on Cycas rcvoluta, and says it is a very common 

 scale throughout the United States, and in his ' ' Contribu- 

 tions to the Knowledge of Massachusetts Coccidse," III, it is 

 stated to be "a very common pest in all greenhouses at Law- 

 rence." Now that it has established itself In Australia, it 

 will be interesting to compare it minutely with Aspidiotus car- 

 podeti of Maskell, a New Zealand species infesting Carpodetus 

 serrahis and Vitcx littoralis, and which Professor T. D. A. 

 Cockerell has put down as a synonym of hcderce. But I can- 

 not quite follow Prof. Cockerell. In January, 1899, in the 

 " First Supplement to the Check-List of the Coccidse," Asp. 

 carpodeti is one of 23 synonyms of hedera ; yet in May of the 

 same year the same author, in " The Industrialist," identifies 

 a species from Oregon as Asp. hedercev&r. carpodeti, Mask., 

 on oleander and pandelon. 



Quite recently I had an opportunity of examining the type 

 of Maskell' s A. carpodeti, and compared it with specimens of 

 A. hederes as determined by Mr. C. L. Marlatt. I am now 

 quite satisfied that carpodeti is a very distinct species, with 

 four lobes, median pair unusually large, second pair very simi- 

 lar to nerii. Four groups of spinnarets or ventral glands, 

 cephalolaterals 4 to 6 orifices, caudolaterals 8 to 12. 9 pupa- 

 rium convex, brown in color ; exuviae central, quite blackish. 

 Maskell says that some specimens are slightly elongated. 

 Average diameter 1.75 mm. $ puparium narrower, parrell- 

 sided, brownish in color. Average length 1.58 mm. Adult 

 of normal form. Antenna of ten joints, the fifth, seventh, 

 eighth and ninth longest. Abdominal spike excessively long, 

 at its base a large tubercle. 



The very prominent median lobes are distinctly unlike the 

 abdominal extremity of hederce.
