Australian and Tasmanian Malacodermidae. 173 



antennae longer with the serrations more pronounced. 

 Its front femora are normal but its hind tibiae are remark- 

 able ; just before the middle they are suddenly com- 

 pressed, the compressed portion being red * ; seen from 

 above the compressed part appears slightly wider than the 

 rest of the tibiae whilst from the side it appears to be 

 much narrower. This appearance at first appears to be 

 accidental, but in another species {distortipes) before me 

 it is even more pronounced.

var. TASMANiENSis, n. var. 



I have eight specimens of what I regard as a variety of 

 this species. They differ from the above noted ones in 

 being darker (most of them have the elytra purplish-blue), 

 and with the punctures much coarser. In two males the 

 abdomen is red except at the apex, the hind tibiae are as 

 described above even to the distorted portion being red in 

 one and almost as dark as the rest of the tibiae in the 

 other. The abdomen of the females varies from entirely 

 dark to dark only at the apex. In one of them the apical 

 half of the terminal joint of the antennae is distinctly 

 reddish.

Hypattalus collaris, Lea, P. L. S., N.S.W., 1898, p. 575. 



The types of this species are females. I have tabulated 

 it, however, with the species having the front femora of 

 the male simple as it is evidently allied to distortipes, and 

 probably has the hind femora distorted in the male.

Hypattalus viridis. Lea, /. c, p. 576. 



Although I do not know the male of this species (the 

 type is a female) I have tabulated it with those having the 

 front femora of the male simple, as it is evidently allied to 

 calcaratus, notwithstanding its simple hind tibiae.

* In one specimen, in the other it is almost as dark as the rest of 

 the tibiae.
