the legs and the anteuual formula} are identical in all thi'ee forms ; 



and the marginal hairs in all are flattened and slightly dilated at the 



extremity (fig. 1). Coffece ?ivn\. JiJicum 



can scarcely rank as more than varieties 



of hemisph(srlcum. I note that Pi'of. 



Cockerell, in his recently published 



"Check-List of the Coccidcs'" (Bulletin 



of the Illinois State Laboratory of Fig. i_ 



Natural History, vol. iv, pp. 318— 339), is of the same opinion as 



regards the first-named, and suggests the propriety of the second 



being in the same position. At Kew I find the typical form on Cycas 



Jenkinsiana (from India). The variety coffece (which Mr. Newstead 



informs me is new to our British lists) occurred on Goffea liherica, 



Stangeria schizodon (from Natal), Ei^anfhemum cinnaharinuin, Glero- 



dendron speciosum, Boivenia spectahllis (from Queensland), and 



Casimeroa edulis (the Mexican apple). The dermal cells on the dried 



scales appear as closely studded paler dots on the darker ground. 



Yar.JiUcum occurred on several species of fern, and on Nepenthes 



Rafflesiana. 



[Typical forms occurred on Eugenia malaccensis ; var. Jilicum, 

 Doug., on Leucadendron argenteum, and var. coffece on Coffea arabica. — 

 R. N.] 



Lecanium hesperidum, Linn. — I found this species upon both 

 surfaces of leaves of BertoJonia Marchandi. The insects were ranged 

 along the prominent nervures of the leaf. The adult females covered 

 newly excluded larvae. The same species occurred on Lucuma multi- 

 flora and Dalbergia lanceolaria. I did not notice it upon any citrus 

 plants, where it might with reason have been expected. 



[Also in the open air on Hedera amurensis, November, 1896. — 

 E. N.] 



Lecanium longultjm, Doug.^Upon leaves and twigs of Cassia 

 flstula (from India). I note that Mr. Douglas has also recorded this 

 insect from Kew. His examples were taken upon Averrlioa caramhola 

 and Spathopliyllum hlandum. 



Lecanium niguum, Nietn. — There were examples of this species 

 upon leaves of Seliconia metallica (from Brazil). The colour of the 

 mature $ varies considerably. It is as often a deep chestnut colour 

 as black. I agree with Mr. Maskell in considering that L. depressum, 

 Targ.-Tozz., and L. hegonice, Doug., are identical with, or at the most, 

 varieties of, Nietner's species.
