384 Transactions. — Zoology. 



Adult male dark-red; length, exclusive of the spike, about 

 ■Jjjin. ; the spike is about as long as the abdomen. Antennae, 

 feet, Sec, presenting no special characters. 



Hah. In Australia, on Hakea sp. My specimens were 

 sent by Mr. Olliff, from Sydney. 



This species may be recognised by the entire absence of 

 abdominal lobes in the adult female, and their presence, con- 

 spicuously, in the pellicles ; also by the groups of rostral 

 spinnerets in the first pellicle and the large oval ones in the 

 male pupa. In Aspidiotus acacice, Morgan, similar groups are 

 seen near the rostrum, but in the adult state; and although 

 the adult female of that species has very small and (appa- 

 rently) not protruding lobes, yet these are present. I believe 

 that A. hakccE is clearly distinct. 



Aspidiotus virescens, sp. nov. Plate XVIII., figs. 7-10. 



Puparium of female subcircular, flat, greyish- white ; dia- 

 meter about 1^0^^^- Pellicles subcentral ; the larval pellicle 

 is distinctly green, the second pellicle greenish in the middle 

 and yellowish on the borders. The texture of the secreted 

 portion of the puparium is thin and papery. 



Puparium of the male subcircular, snowy-white, flat ; the 

 single pellicle subcentral, green. Diameter about Tr'gin.; the 

 texture very thin, delicate, and papery. 



Adult female of the usual peg-top foi'ui ; colour yellow, 

 with a greenish tinge. Length about -oV^"^- Abdomen ending 

 in six subequal lobes, not set closely together ; each lobe is 

 narrow at the base, widened in the middle, and narrowed 

 again towards the end; between the lobes, and extending along 

 almost the whole abdominal margin, are very numerous broad 

 scaly hairs, the ends of which are deeply serrated. There are 

 four groups of spinnerets ; upper groups with 17-21 orifices, 

 lower groups with 8-13. Dorsally, there are great numbers of 

 tubular spinnerets. 



Adult male yellow, with a greenish tinge ; length about 

 Jgin., exclusive of the spike, which is about half as long as the 

 body. The organs present no distinctive feature. 



Hab. In Australia, on Eugenia smithii. My specimens 

 were sent by Mr. Froggatt ; locality not named, but probably 

 near Sydney. 



This species may be distinguished by the terminal lobes 

 and scaly hairs, as well as by the papery, thin puparia, and 

 the distinctly green pellicles.

Occurs in India, on orange, at Khandallah. My specimens 

 were sent by Dr. Alcock, Superintendent of the Indian 

 Museum, Calcutta.
