Heteromastix distortus, n. sp. {Figs. 32, 40, 112.) 



^ . Dark brown ; prothorax, base of antennae, legs (except tbe 

 tarsi, base of hind femora and apex of hind tibiae) flavous. 



Head wide, depressed between eyes, impunctate, or almost so. 

 Antennae long, 3rd-5th joints curiously inflated and distorted, 4tli 

 largest of all but no longer than 6th. Prothorax about twice as wide 

 as long, sides regularly rounded. Elytra densely and minutely 

 punctate, with traces of feeble raised lines. Penultimate segment of 

 abdomen semicircularly excised. Front tibiae deeply notched at 

 apex ; basal joint of front tarsi strongly curved. 



Length f)^ mm. 



Hal. N. S. Wales, Sydney (type in Macleay Museum). 



The two specimens before me are both injured ; one 

 having the head partly eaten and both with the terminal 

 joints of antennae missing; they may also be somewhat 

 faded and the parts described as dark brown may possibly 

 be black in living specimens. The antennae and front 

 legs of the male (the only sex known to me) are so 

 peculiar, however, that it cannot be mistaken. The 4th 

 joint of the antennae is very peculiar, from one direction 

 it appears widest at the base, from another at the apex ; 

 the 5th is lobed near the base and slightly shorter than 

 the 6th ; each of the three distorted joints is obliquely 

 produced at the apex. The head towards the base appeal's 

 to be obliquely strigose, but this appearance is due solely 

 to the pubescence. 



Heteromastix macleayi, n. sp. {Fig. 33.) 



(J. Flavous; elytra (base and sides diluted with flavous) 

 and abdomen dark brown ; metasternum somewhat paler ; three 

 terminal joints of antennae infuscate. 



Head wide. Antennae rather long and stout ; 9th joint long, 

 strongly inflated and foveate near apex ; 11th distinctly longer than
