]84 Mr. G. C. Champion on 



late. Fifth ventral segment emarginate. Penis-sheath bisagittate, 

 the upper portion strongly acuminate at the tip. 

 Length 7, breadth 2 mm. 



Hab. Australia, Queensland border (Blackburn). 



One male, sent me many years ago by Blackburn. Two 

 similarly-coloured examples — one in the Museum labelled 

 " Melbourne," acquired in 1853, the other from Inverell, 

 N.S.W. (J. Stephen), recently received from Mr. Carter — 

 with the elytra subparallel in their basal half, are probably 

 females of the same species ; but they have the fifth ventral 

 segment deeply excavate down the middle, a character 

 usually indicative of the male. 



Ictistygna, Pascoe.* 

 Eurigeniomorjjhus, Pic, Le Naturaliste, 1897, p. 25. 



This genus was based upon a single species, several others 

 being now known, all Australian, the sexes of some of them 

 being very different. Pascoe noted the closed anterior 

 coxal cavities, and for that reason referred Ictistygna to" 

 Lagriidae. The resemblance to the Pedilid genera Diamlla 

 and Egestria is certainly very striking, and unless the 

 coxae are pushed forward it is scarcely possible to see 

 whether the acetabula are closed or open. The tibiae are 

 conspicuously denticulate or setulose externally in all the 

 species, this being especially noticeable on the intermediate 

 pair. The six before me may be tabulated thus : — 



a. Tibiae denticulate externally; head and pro- 

 thorax more coarsely punctate. 

 a 1 . Body black in <$ (the elytra reddish-brown in 

 /. adusta, type), brown in $. 

 a 2 . Head and prothorax more coarsely punctate. 

 a 3 . Legs red ; elytra coarsely, rugosely punc- 

 tate ; antennae long in (J adusta, Pasc. 



b 3 . Legs black; elytra coarsely, subcon- 

 fluently punctate ; antennae shorter in <$ ; 



[$ unknown] macleayi, n.sp. 



6 2 . Head and prothorax finely punctate. 



c 3 . Elytra fasciate, dull fasciata, n. sp. 



d 3 . Elytra with suture infuscate, shining . biformis, n. sp. 



* Incorrectly placed by me as a synonym of Enrygenius, Laf.,
