some Species of Ceroplastes. 191 



Ceroplastes florideasis^ Com stock . 



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

 that his species C. jloridensis 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. Jloridensis, and find that 

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

 tive, and that thej are really sessile witli a subcutaneous 

 connecting-tube. 



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



Ceroplastes australue, Walk. List of Homoot. in Brit. Mus. iv. (1852) 

 p. 1087. 



Specimens in the Museum collection, labelled " australice, 

 Walk.," vi^hen denuded of their waxy covering exhibit the 

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

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

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

 denuded insect 2*25 millim.), but they are immature, and 1 

 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. J\I., labelled only 

 " Sydney," are similarly immature examples of ceriferus, 



Ceroplastes chilensisy 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 chilensis in 

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

 marginal plates. Tlie 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 tlie 

 specimens weie lound by Mr;-', Graham during her residence 

 in the Brazils and Chili [he refers to chilensis and janairensisj. 

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