"sparsely covered with short black hah^s": those of var. 

 australis are numerous and long : the type has on the 

 abdommal margin six arched hairs, longer than the dorsal 

 ones and shorter than the terminal ones, and according to the 

 figure (Ins. Life, p. 91) these are distinctly separate : in var. 

 australis there are three sets of arched hairs in pairs. I do 

 not feel inclined at present to consider these differences suf- 

 ficient to require a new species for this insect. 



A question arises now whether perhaps Australia may not 

 be the original home of all leery cb. There is scarcely any 

 doubt about /. imrchasi; I. hoehelei is certainly Australian; I. 

 csgyptlaca and I. roscB are found there : I. montserratensis 

 seems to be possibly a variety : I. seychellamm has as yet been 

 reported on sugar-cane only from Mauritius : and I. j^alineri on 

 grape from Mexico : but even these may after all turn out to be 

 Australian also. I may mention that Mr. T. Cockerell has 

 sent me specimens of an Icerya from New Mexico, with a 

 long and narrow ovisac which is not grooved : I shall not be 

 surprised if this is the adult form of I. pahneri. 



Monophlebus crawfordi, Maskell. Plate VIII., figs. 9-14. 



In 1892 (N.Z. Trans., vol. xxv., p. 243) I gave details of 

 the characters which, in my opinion, separated the varieties 

 levis and _2Ji/osior from the type, as far as regarded the adult 

 females. Since then I have examined carefully specimens of 

 larvae, with the result that I find the following differences : — - 



M. craiofordi, type. Larva reddish-brown : length 4^m. to 

 ■Jjin. Dorsum covered with many longish, thick, subclavate 

 hairs, and bearing some (not many) circular multilocular 

 spinnerets. Feet only moderately spinous : spines slender. 

 Antennae of six joints, which might, perhaps, be considered as 

 five, the separation of the third and fourth joints being fre- 

 quently inconspicuous. 



M. crawfordi, var. levis. Larva reddish-brown : length 

 averaging -i'^■\l-l. Dorsum bearing great numbers of large cir- 

 cular multilocular spinnerets and many short fine sjDiuy hairs. 

 Feet scarcely spinous : spines slender. Antennae as in the 

 type, with uncertain separation of the third and fourth joints. 



M. craiofordi, var. pilosior. Larva reddish-brown : length 

 averaging ■^-^m. Dorsum covered with many longish sub- 

 clavate thick hairs, with several slender spiny hairs, and very 

 few circular large multilocular spinnerets. Feet moderately 

 spinous. Antenna as in the type and in var. levis. 



The feet appear to be longest in var. pilosior and shortest 

 in the type, but the difference is not very marked. 



Taking into consideration the foregoing characters, the 

 differences noted last year in the adult females, and the gene- 

 ral features and modes of propagation and growth in all these
