the elytra are very acute, as in novaehollandiae, semipunctata, 

 and cucullata. The four species may be thus distinguished : — 



Prothorax entirely black. 



Elytra with dense punctures throughout ... cucullata 



Elytra with dense punctures only on black 



parts semipunctata 



Prothorax entirely pale. 



Elytra with apex only black nigroapicalis 



Elytra with black postmedian spots as well ... novaehollandiae 



Emenadia rufofasciata, n. sp. 



<3 . Colour variable, but elytra always with a broad, 

 sub-basal, and more or less reddish fascia. 



Head polished and impunctate except between bases of 

 mandibles, where the punctures are fairly numerous and 

 rather sharply defined, although small. Prothorax longer than 

 wide, hind angles very little divergent, medio-basal lobe rather 

 wide and obtusely pointed, not notched ; with shallow and 

 rather sparse punctures, becoming more numerous on sides. 

 Elytra each with a rather shallow longitudinal impression; 

 punctures moderately dense and oblong, with a laminated 

 appearance posteriorly. Second joint of hind tarsi about once 

 and one-half as long as wade, subtriangular in transverse 

 section. Length, 4-6^ mm. 



9 • Differs in having second-tenth joints of antennae 

 serrate instead of biflabellate, sides of mesosternum more con- 

 vex (although not visible from above), legs slightly shorter, 

 and front tarsi narrower.

In many respects close to difficilis, but the pale portion 

 of elytra in the form of a transverse fascia, instead of (w T hen 

 the elytra are not entirely pale) longitudinal markings. Of 

 the nine specimens before me no two are coloured exactly 

 alike, but they all agree in having a wide fascia commencing 

 near the base of the elytra, and terminating about the 

 middle ; on some specimens it is no longer than the basal 

 black portion, but on others it is thrice as long, it is without 

 interruption from side to side and is of a more or less bright 

 red, but on some specimens almost flavous ; the legs, except 

 for the tibial spines, and the claws are sometimes entirely 

 black, but on some specimens many parts are reddish ; the 

 basal joints of the antennae are reddish, the other parts
