710 HETEROMERA,. &C., FROM TROPICAL AUSTRALIA, 



Hah. — King River, iSTortliern Territory (W. McLennan). 



Two specimens, sex doubtful, sent from the National Museum, 

 Melbourne, differ from E. ccerulea Champ., in the following, 

 inter multa alia. Size smaller, prothorax black, the sculpture 

 closer and rugose, basal teeth more acute, elytra of that elusive 

 colour peacock-blue-green, which is blue or green according to 

 the point of view {E. coerulea is purple-blue), the sculpture 

 throughout coarser, elytral intervals more convex. Of the genus 

 Ectyche, six species have been described, of which I think I 

 possess five. These are all black except E. ccrrulea Champ., of 

 which I have cotypes from the author. Type in the National 

 Museum, Melbourne.
