the surface thickly, finely punctate. Elytra moderately elongate, 
nearly twice the width of the prothorax, densely, finely punctate, 
the interspaces somewhat granulate ; each elytron with four feeble 
costae. Beneath rather sparsely punctured. Claws simple. 
$ . Fifth ventral segment broadly and deeply triangularly emar- 
ginate at the apex; the genital organs partly exposed. 
Length 7^-9, breadth 2-24 mm. ( ^ ? ). 
Hah. Tasmania — Hobart. 
This insect greatly resembles D.miranda^ Newm. 
but differs from it in having the antennas simple in both 
sexes, the apical joint in the female much shorter and 
not constricted at the middle. Also found by Mr. 
Atkinson in Tasmania.

The members of this genus bear a remarkable resem- 
blance to some of the Lycidse inhabiting the same localities.

These forms were collected together at Hobart, by 
Mr. Walker, and there can be very little doubt that they 
belong to one variable species; one of the specimens 
is intermediate between P. ductus and the variety with 
ferruginous elytra. In typical P. hsemorrhoidalis the elytra 
have only the apex ferruginous. Lacordaire suspected 
that the males only had the joints 3-7 (not 3-8) broadly 
widened;* but this is not the case, the antennas being 
similarly formed in both sexes. The colour- differences

has nothing to do with the genus Pseudolycus.
