Heteromastix tenuis, Lea. 



The female differs from the male in being somewhat 

 shorter, antennae decidedly shorter, prothorax without a small 

 subbasal notch on each side, and abdomen simple. 



Heteromastix mirabilis, Lea. 



The female differs from the male in being somewhat 

 smaller, antennae thinner and simple, legs shorter, and in the 

 abdomen; it is in fact scarcely distinguishable from the females 

 of many other species of the genus, although the male is one 

 of the most distinct. 



Heteromastix macleayi, Lea. 



Three males from Northern Queensland (Innisfail and 

 Cairns) appear to belong to this species, but differ somewhat 

 from each other and from the description of the type. One 

 in size and colour is like the type except that the four apical 

 joints of its antennae are infuscated; the second is larger, 

 3 mm., and has the joints after the second infuscated, becom- 

 ing almost black after the eighth, its elytra have the basal 

 fifth flavous and sharply defined from the black ; the third 

 is still larger, 3'75 mm., and has the joints of the antennae, 

 after the second, still darker, and slightly more of the elytra 

 pale. A female, mounted with the second male, agrees well 

 with it in colour and size, but has the antennae shorter (the 

 three apical joints only about half the length of those in the 

 male), with the ninth joint and the abdomen simple. 



Heteromastix dolicocephalus, Lea. 



On the male of this species the subapical segment of the 

 abdomen is gently emarginate, the emargination becoming 

 slightly stronger in the middle, not suddenly as in most males 

 of the genus ; the antennae are decidedly longer than in the 

 female. 



Heteromastix amabilis, Lea. 



Prior to being published this species was given the manu- 

 script name of elegcms, and was so noted in the table ( 12 > ; 

 afterwards the name was changed to amabilis, and unfortun- 

 ately the necessary alteration was not made in the table. 



Heteromastix bryanti, Lea. Figs. 1-3. 

 As the terminal joints of the antennae were not figured 

 at the time of the description of this species, views of them, 

 from different directions, are given for comparison with those 

 of other species.
