Longicornia of Australia and Tasmania. 167 
and covered with a thick tomentum over almost their whole ventral 
surface ; just in front of each of the smooth spaces the tomentum 
is elongated to form a narrow transverse brush of fulvous hairs ; 
the fifth ventral segment has a small rounded tomentose depression 
on each side, and its sinuately emarginate apex is also fringed with 
tawny sete.

The thoracic spines of this species seem to vary con- 
siderably in size. They are quite rudimentary in some 
of the smaller males, and are rather long in some of the 
larger females ; distinctly longer than in the two speci- 
mens which served as the types.

This species, originally described from Tasmanian 
examples, has since been taken in S. Australia (Bakewell), 
Queensland (¢ and 2), (Challenger Expedition), and, 
according to Pascoe, in Victoria and New South Wales. 
Mr. Pascoe has, in his last catalogue of Australian 
Longicorns, rightly placed the two forms as sexes of the 
same species; but the name Phaolus must, I think, be 
taken in preference to Jotherium, as it stands first on the 
page in which the two names were first proposed, and 
was founded on male examples.
