Mr. Waterhouse thouglit it possible* that Lycus atratus 

 was a variety of his hacmorrhoidalis, and that both were 

 varieties of rujipennis. There are at least three entirely 

 black species occurring in Tasmania, practically any one 

 of which might be atratus; but Blackburn has formerly 

 described a species from Tasmania as the atratus of Fab- 

 ricius, and unless it can be proved to be the contrary by 

 examination of the type (if such is still extant), I think the 

 species described by him as atratus should be accepted as 

 such. This species, of which only the female was known 

 to Blackburn, is rather small and narrow, with a very short 

 rostrum ; 3rd-9th joints of antennae about as long as wide 

 (with the produced portions much less than in the male of 

 rujipennis), and the reticulation of the elytra rather less 

 clearly defined than usual. Of the other black Tasmanian 

 species insigni'pcnnis can be readily distinguished by the 

 elytral punctures being in single instead of in double rows ; 

 whilst mocreiis has the rostrum long and shining. 



Hah. Tasmania (widely distributed).
