many short spiny hairs on each joint. Bostrum and mentum 

 absent. Anogenital ring simple, hairless ; anal tubercles 

 absent, but there are two short caudal setae. Although the 

 short filaments on the dorsum look like hairs, they are not 

 so, as they dissolve in potash, and the epidermis bears great 

 numbers of irregularly oval cells, each with a central small 

 orifice from which evidently the semi-waxy filaments spring. 



Female of the second stage, larva, and male not observed. 



Hab. In Australia, on Banksia integrifolia. Mr. French 

 sent me specimens first from Melbourne, stating that they 

 were " on dead twigs " ; later he sent me two on leaves. After- 

 wards Mr. Koebele sent me two from Semaphore, South Aus- 

 tralia, on the same plant. 



This is a peculiar species, which is clearly not far re- 

 moved from C. immane, Mask., the gigantic Coccid from 

 central Australia. It is quite distinct from any others of the 

 genus, and I should be glad to obtain a male. The skin of the 

 antennae and feet seems to be much less chitinous and hard, 

 than usual, and it was only after several attempts that I suc- 

 ceeded in preparing specimens for examination. 



Genus Monophlebus, Leach.

Mr. Koebele has at different times during his second ex- 

 ploration in Australia sent me specimens which he refers to in 

 his letters as M. craivfordi. For some time I also considered 

 them to belong strictly to that species ; but on careful exami- 

 nation I have come to the conclusion that they differ some- 

 what ; and, although I am not yet prepared to consider them 

 all as specifically distinct, yet I consider two as varieties, and 

 a third quite separate. In outward appearance there is 

 scarcely anything at all to distinguish them, except that the 

 " long white anal seta" mentioned by Mr. Koebele in 1889, 

 and which I have never seen on the type of M. craivfordi, is 

 visible on the insect which I name in this paper var. pilosior. 



The following, therefore, is a synopsis of this species and 

 its varieties as known to me at present : — 



Monophlebus craiufordi, type : Female varying in length 

 from i-in. to ^in. ; colour yellowish-red, with longitudinal 

 bands of purple ; antennae of nine joints, equal in length 

 except the last, which is rather longer than any of the 

 others ; feet moderately spinous ; epidermis clothed 

 with short fine hairs interspersed with very large 

 numbers of circular spinneret - orifices ; no long anal 

 seta.
