E. tricolor), of six undoubtedly conspecific females, four have 

 the head entirely red and two have it red and black, the colours 

 being as sharply limited as in E. cajnto, but reversely placed. 



Emenadia pictipennis, n.sp. 



(J. Dark reddish-brown, abdomen and all the appendages paler; 

 elytra reddish-brown along basse, suture and margins, the sides 

 each with three black patches : one basal, one subapical and the 

 largest antemedian, the interspaces testaceous. Undersurface 

 (and less noticeably the legs) clothed with fine sericeous pubes- 

 cence. 



Head shining; strongly punctate throughout, but punctures 

 denser near mandibles than near summit, the hinder slope very 

 coarsely punctate; middle strongly raised and somewhat rounded. 

 Prothorax very densely punctate, the punctures more elongate 

 and confluent posteriorly than in front; base about twice the 

 width of apex ; posterior angles acute and projecting ; sides 

 lightly but distinctly sinuous; scutellar lobe shining and slightly 

 raised. Elytra divided from before the middle, each impressed 

 along middle; with dense and more or less elongate punctures.. 

 Sterna, especiall}'' the mesosternum, densely punctate. Length 9, 

 width 3| mm. 



Hah. — Cairns (Macleay Museum) and Mackay, Q. (C. French). 



The elytra appear to be supplied with six black and four pale 

 maculae. In both this and the following species the head is 

 almost triangularly raised in the middle (this character alone is 

 sufficient to distinguish them from all previously described Aus- 

 tralian species), and the scutellar lobe presents an appearance 

 as of having been supplied with a tubercle or spine that, being 

 broken off, leaves a polished scar to mark its position. 



Emenadia semipunctata, n.sp. 



Q. Black; abdomen, antennae (in whole or in part), palpi, spurs 

 and claws red; elytra pale stramineous, but each with three black 

 patches : the first rather narrowly margining the base, the second 

 (subtriangular) just before the middle and touching the side b
