some Species of Ceroplastes. 191 



Ceroplastes Jloridensis, Com stock. 



Comstock, in his Annual Report for 1880, p. 331, mentions 

 that his species C. jioridensis carries similar arrow-shaped 

 tubercles (or stigmatic spines). I have examined the common 

 Ceylonese species, which (on the authority of Dr. L. O. 

 Howard) I have placed under G. jioridensis^ and find that 

 the arrow-shaped appearance of the spines is here also decep- 

 tive, and that they are really sessile with a subcutaneous 

 connecting-tube. 



Ceroplastes australim, Walk. (PI. IV. tig. 4.) 



Ceroplastes amtralice, Walk. List of Homopt. in Brit. Mus. iv. (1852) 

 p. 1087. 



Specimens in the Museum collection, labelled " australtce, 

 Walk.," when denuded of their waxy covering exhibit the 

 long anal process and all the other characters ot C. ceriferus. 

 The waxy test is thick and irregular in form. These examples 

 are very small (the tests only 3*50 millim. long, and the 

 denuded insect 2*25 millim.), but they are immature, and I 

 have little hesitation in asserting that they are young- 

 examples of ceriferus. The anal tubercle is very prominent 

 (see fig. 4), standing up like the spout of a tea-pot. 



Other unnamed examples from the B. M., labelled only 

 " Sydney," are similarly immature examples of ceriferus. 



Ceroplastes chilensis^ Gray. 



Some specimens labelled chilensis, Gray, also appear to me 

 to be immature examples of ceriferus. 1 am informed by 

 Mr. C. O. Waterhouse that these are the type specimens 

 described by J. E. Gray in ' Spicilegia Zoologica.' Signoret, 

 in his ' Essai ' (pi. vii. fig. 5), gives a figure of cliilensis in 

 which the test is represented with a series of well-defined 

 marginal plates. The examples under examination have an 

 irregular homogeneous waxy test, as in typical ceriferus. 

 The denuded insect shows the long horn-like anal tubercle. 

 The body is deeply cleft in front, but this is merely an 

 accident due to its position on a very thin twig, causing the 

 lateral margins of the body to grow round and embrace the 

 support. 



With regard to the locality, Mr. Waterhouse writes me as 

 follows : — " Gray, at the end of his description, says the 

 specimens weie lound by Mrs. Graham durmg her residence 

 in the Brazils and Chili [he refers to chdensis and Janairensis], 

 The locality is probably correct, but 1 can find no mention of
