ilicis and K. reniformis, as well as species of LeccDiium, etc. Mr. 

 T. Pergaude suggests that Kermes is in reality allied to Eriococcus. 

 This had not occurred to me, but after going over the characters 

 with this thought in mind, I am inclined to agree with him. 



ilicis (L.)- 



Coccus ilicis L., Syst. Nat., Ed. x, 1758, p. 455. 



Linne gives no description, but cites Reaumur. The insect 

 described and figured by Re'aumur is the globular black species, 

 later named K. hauhinii, not the K. vermilio. The latter there- 

 fore remains valid. 

 Kermes quercus (L.). 



Coccus quercus L., Syst. Nat., Ed. x, 1T58, p. 4.55. 



Linne gives no description, but cites, " Re'aum. ins. 4, t. 6, f. 

 1-4, and alia f. 8, 9, 10. 



Reaumur's figures 1-4 represent Kermes renifornm of Signoret 

 and authors, which must therefore fall as a synonym of K. 

 quercus. The figures 8, 9, 10, are of a large Pulvinaria, also 

 found on oak. 



Kermes quercus Newst. MS. wnll need a different name. The 

 Lecanium quercus " L. " of Signoret is not the Linuean insect. 



Fseudokermes armatus (Ckll.). 

 Lecanium armatum Ckll., Am. Mag. N. Hist., June, 1898, p. 436. 

 Mr. Pergande made a mount of the second stage from out of the 

 original lot. It is 1 mm, long approximately, and has the legs and 

 antennae mere stout, conical protuberances, extremely small; skin 

 Avith numerous figure-of-8 glands; anal plates large, mouth parts 

 well-developed. 



Lecanium coiFeae Walker. 



ListHomop. Ins. B. M., 1852, p. 1079. 



This is said to have transverse ridges, -which suggests oleee ; but 

 it is flat and only 2 mm. long, so it must be in the second stage 

 only, and therefore may be hemisphcericum. Tradition in Ceylon 

 identifies it with hemisphcericum, and I have used the name coffece 

 for that insect accordingly. Mr. Pergande, however, tells me he 

 saw specimens in the Berlin Museum labelled coffece, and believed 

 to be authentic, and they were olew. On the whole, the name 

 coffece had better be dropped.
