Australian and Tasmanian Malacodermidae. 151 



and apparently 10-jointed, but the true 2nd joint is hidden 

 by the 1st, the true 3rd (here referred to as the 2nd, as it 

 is by other entomologists) being usually enormously inflated 

 in the males* ; the 1st joint is also more or less inflated. 

 The front femora are sometimes deeply groved in the 

 males, and the 2nd joint of the front tarsi in the males is 

 always of peculiar shape and tipped with black. The 

 females of many species are very closely allied, and it is 

 difficult to satisfactorily identify some of them from the 

 descriptions ; but the males are always distinct, and given 

 satisfactory descriptions their identification should be 

 easy. 



In addition to the species here noted or described there 

 are about twenty others before me ; all, however, repre- 

 sented by discoloured males or by females only, and I have 

 not considered it advisable to describe them. 



The following species are unknown to me : — 



Guttulatus, Fairm. — A small and evidently very distinct 

 species, having the prothorax scarcely transverse. It seems 

 to be allied to sinus. The type was probably a female. 



Fasfidiosus, Fairm. — A small species with elytra! mark- 

 ings much as in lellvlus and many others, but the prothorax 

 with " punctis 2 oblongis fuscis." The type was probably 

 a female. 



Insignicornis, Fairm. — A small species evidently resem- 

 bling eyrensis, cams, etc. Both sexes were known to 

 Fairmaire, but all he says of the 2nd joint of the antennae 

 of the male is that it is inflated. 



Rufovirens, Fairm. — Evidently very close to the above 

 species. The type was probably a female. 



Ohlongosignatiis, Fairm. — A small species evidently rather 

 closely allied to trisignatus. 



Asperipennis, Fairm. — Appears to be a very distinct 

 species of medium size, with the elytra entirely metallic- 

 blue and granulated. 



Quinquep)lagiahLS, Fairm. — Evidently a very ordinary- 

 looking species of medium size and allied to conicicornis, 

 plagiaticollis, villosus, etc. 



Bugulipennis, Fairm. — Evidently allied to the above 

 species; I have seen numerous species which almost 

 agree with the description. 



* It is to be noted that this joint usually looks different in shape, in 

 almost every direction it is viewed from, and figures have been given 

 of the antennae of several species as viewed from different aspects.
