of the fluffy hairs from the surface of the leaf. Tlirough this 

 scale a narrow semicylindrical groove is visible, and on turning 

 over the puparium the insect is seen occupying this groove, 

 the pellicles being terminal. The whole is inconspicuous, 

 being about the same colour as the leaf. Length, about j^in. 



Puparium of male similar to that of the female, but smaller. 

 Length, about ^in. 



The adult female is yellow, exhibiting the very large 

 median lobes, hairs, and deep indentations of the type. There 

 are five groups of spinnerets : upper group with 2 to 3 orifices ; 

 upper laterals, 8 to 11 ; lower laterals, 5 to 6. 



Adult male unknown. 



Eab. In Japan, on Qiiercus cuspidata. My specimens 

 were sent from Yokohama by Mr. Koebele. 



Mr. Cockerell, in his description of M. craicii, in a paper 

 published by the U.S. Department of Agriculture, 1896, 

 entitled " Some Mexican and Japanese Injurious Insects," 

 makes no mention of any groove in its puparium, and states 

 that it has four groups of spinnerets. This last character is 

 always somewhat variable, and perhaps in his specimens the 

 two anterior orifices were absent. The groove may have been 

 accidentally omitted by him. All other characters are abso- 

 lutely identical with mine. Curiously, on the very same page 

 of his paper he reports a grooved species from Central 

 America, M. carinatus (carinatal), but that is clearly distinct 

 in other particulars. I know of no other species with a similar 

 groove except the male of Fiorinia astelice. 



Genus Chionaspis. 

 Chionaspis aspidistrse, Signoret, and its allies. 



In the "Entomologists' Monthly Magazine" for March, 

 1896, p. 60, Mr. Newstead discusses the affinities of C. aspi- 

 distrcB and C. hrasiliensis, Sign., concluding that the two are 

 identical. In a paper sent to the same journal (see Ent. Mo. 

 Mag., Oct., 1896, p. 223) I have expressed the view that, 

 whilst possibly they may be of the same species, they are in 

 all probability variations, and that as both were described by^ 

 Signoret in the same paper (March, 1868) it may be con- 

 venient to consider aspidisWa the type, alphabetically. Since 

 then I have been led to re-examine the two in connection 

 with C. thecB, Mask. (" Indian Museum Notes," vol. ii.. No. 1,. 

 1891, p. 60), specimens of which were sent me this year by 

 Mr. Koebele, from Formosa, on tea-plants. I have also re- 

 examined specimens of C. aspidistra, var. mussandcB, Green 

 (Ind. Mus. Notes, vol. iv., No. 1, 1896, p. 2). 



I do not find any important differences in the puparia of 

 these forms. The male puparia of my Formosan specimens
