Coccidse in the British Museum, 377 



conspicuous circular plate (figs. 2, 3), those on thoracic area 

 much smaller than the others. These spines are easily 

 detachable and are often missing, especially in older examples, 

 when the circular base remains and has the appearance of a 

 large circular pore. Pygidium (tig, 4) normally with six 

 stout, prominent, bluntly rounded lobes. In some examples 

 the lobes are very irregularly developed, one or more being 

 often missing. Margin beyond the lobes strongly incrassate 

 and irregularly cristate. Paraphyses more or less obscured 

 by and merged in the thickened margin. Squames broad, 

 stout, truncate, almost as large as the lobes, not fimbriate, 

 apparently tubular, with a deep cleft on one side of the tube 

 {^g. 5). No circumgenital glands. Some minute circular 

 pores scattered irregularly over the surface of the pygidium. 

 Length 0*75 to 1"50 mm. 



On undetermined plant. Algoa Bay. Collected by 

 Dr. Pereira. 



Allied to Aspidiotus cladii, Mask., which it resembles 

 closely in colour and texture of puparium and in nature of 

 pygidial squames, but from which it may be separated by the 

 much shorter paraphyses and more conspicuous lobes of the 

 pygidium.

The collection contains some beautiful examples of a 

 Lecanium from Singapore that, in favourable lights, displays 

 a wonderful iridescent golden film on the dorsum. Micro- 

 scopic examination proves the insect to be identical with 

 L. expansum, var. metallicum [loc. cit.), though these 

 specimens are even more iridescent than the typical examples 

 from Java. They were collected by Mr. H. N. Ridley, of 

 the Singapore Botanic Gardens, on Mtjristica (nutmeg). 



I have also received on loan from Mr. E,. Newstead, of 

 Chester, a single specimen of what is evidently the same 

 species and variety, though I have been unable to examine 

 it microscopically. Tliis specimen is labelled " On shrub in 

 Jungle, Malay Peninsular, Butsib Berar, 2500 ft. Coll. 

 Annandale, 28, VI II. 01.^' 



The dorsum in all the examples is distinctly marked with 

 polygonal plates, as in the type. In those from Singapore 

 the centre of each plate is bare of the golden film ; but 

 in the single example from the Malay Peninsula only the 

 marginal series of plates shows this character, the discal plates
