side. There are no groups of spinnerets, but many single large 

 dorsal orifices. 



Adult male unknown. 



Hab. In Australia, on Acacia sp. Mr. Olliff, of Sydney, 

 who sent me the specimens, was only able to tell me that the 

 tree in question is known by the name of " Easpberry-jam 

 wood," and is a native of Western Australia. 



This insect is not far removed from F. grossularim, Mask. 

 (N.Z, Trans., vol. xvi., 1883, p. 123), but differs in having no 

 groups of spinnerets. 



Genus Poliaspis.

I have received specimens of this from Mr. French on 

 Santalum sp. from Port Darwin, in the extreme north of 

 Australia. Notwithstanding the difference of food-plant or of

 and the sixth is rather longer than either the fourth or fifth ; 

 on the last joint are several hairs. Feet rather long and 

 slender ; the tarsus is rather longer than the tibia ; on the ex- 

 tremity of the tibia are two han-s, and there is a long hair on 

 the trochanter ; the digitules are all fine knobbed hairs, the 

 upper pair rather long. Abdomen tapering posteriorly, as if 

 prolonged in two narrow processes, the ends of which almost 

 touch each other, their internal margins forming the abdo- 

 minal cleft, at the top of which are the usual lobes, rather 

 large and long, and bearing short set^e ; the anal ring aj^pears 

 to have several hairs. Mentum monomerous. Dorsal epider- 

 mis smooth, but the margins exhibit numbers of minute curved 

 marks, interspersed with circular and tubular spinnerets and 

 some small spiny hairs, which seem to be most numerous on 

 the cephalic region. 



Hab. In Australia, on Casuarina sp. My specimens were 

 sent by Mr. Olliff, from Sydney. 



I am not at all sure that any of my specimens (five) are
