isc.o.i 183 



Mr. Morton recently examined examples taken by me at Exmoor, 

 in the autnmn of 1S90, and these also appear to be the var. chri/sop- 

 terus, but scarcely so bright as the Scotch, and much less bright than 

 the Ilfracombe specimens. In these, the condition of the 4th apical 

 fork is variable. 



I am thus inclined to consider the West of England examples, 

 here referred to, as the var. clirysopterus. 



In describing the var. cesareus, McLach., from Jersey, I stated 

 that the apical fork No. 4 is sessile. On examining a large number 

 of specimens taken in 1891, several prove to have this fork distinctly, 

 if only shortly, stalked. The neural structure in this respect is cer- 

 tainly variable, and, perhaps, of secondary importance to colour and 

 markings. The anal structure remains the same throughout.

A NEW ICERYA, 

 AND SOME OTHER NEW COCCIDS FROM AUSTRALIA. 



BT W. M. MASKELL, F.R.M.S. 



Mr. Albert Koebele, an officer of the United States Department 

 of Agriculture, is at present making a second tour in Australasia, with 

 the object of discovering, if possible, parasitic enemies to some of the 

 Coccids, which are so abundant in America. The splendid results of 

 his first journey in 1888, and the wonderful success which followed 

 his discovery of Vedalia cardinalis, and its effects on the " Fluted 

 Scale," have encouraged his Department to make this second effort, 

 and I am sure that the best wishes of fruit-growers and of entomolo- 

 gists in all countries will go with him in his attempt : for, whatever 

 may be the advantages of the application by man of even the best 

 remedies against insect pests, the employment of the " natural enemy " 

 must always be far superior and more effective. 



Mr. Koebele has very kindly supplied me at intervals during his 

 journey with specimens of various Coccids, and I have been able to 

 identify for him, so far, about thirty species, from the Sandwich 

 Islands, from Samoa, and from various parts of Australia. Amongst 

 these, a few, such as Parlatoria Proteus (Queensland), Lecanium tes- 

 sellatmn (New South Wales), Lecanium filicum (Victoria), are known 

 elsewhere ; a species from Honolulu is so like Lecanium depressum, 

 that it is probably only a variety of that species ; a very large and 

 peculiar pinkish Ceroplastes (Queensland) is, I think, probably C.
