the Australian Longicornia. 627 



L. sex-maculata. As the genus is quite unknown in Australia, 

 and the specimen was pinned through the left elytron^ it was pro- 

 bably there by accident. 



Genus Hebecerus. 

 1. Hebecerus niphonoides. 



H. piceus, pube grisea fuscaque varius ; prothorace fumido, 

 linea mediana, nigra, punctata ; elytris basi fasciculis duobus 

 nigris ; antennis fuscis, griseo-annulatis. 



Port Denison. 



Pitchy, covered with a rather coarse greyish pile, varied prin- 

 cipally with brown ; head concave between the antennae, without 

 an impressed line ; antennae ciliated beneath, dark brown, the 

 lower part of the third and following joints greyish ; prothorax 

 very convex, a black punctured line in the middle, and a large 

 dark patch on each side ; scutellum rounded behind, a black 

 lozenge-shaped spot in its middle ; elytra coarsely punctured, 

 irregular at the base, each with two short costse, terminated in a 

 small fascicle of black hairs, costae and corresponding lines along 

 the elytra yellowish-grey, with indistinct brown spots, especially 

 at the sides, posteriorly on the declivity towards the apex another 

 fascicle ; body beneath and legs covered with an ashy-grey pile, 

 speckled with brown, two brown rings on the tibiae. 



Length 5 lines. 



A very distinct species readily to be distinguished by almost 

 any one of the characters given above. It may be remarked here, 

 that some of the species of this genus vary considerably. This is 

 especially the case with Hebecerus marginicollis, Boisd., which is 

 sometimes of a pale reddish-brown, instead of dark-brown or 

 black, its normal colour ; then the antennae vary in length, thick- 

 ness, amount of ciliation, and are either annulated with ashy or 

 uniformly brown ; the broad stripe on each side of the prothorax 

 is narrowed, confined to the posterior part, or absent altogether. 

 I suspect Hebecerus lineola, Newm., is one of its forms. 



2. Hebecerus sord'idus. 

 H. fuscus, fulvescente pubescens ; prothorace linea mediana 

 nigra, nitida ; elytris fortiter punctatis, basi costis duabus 

 brevibus ; antennis griseis. 

 Clarence River. 



Brown or greenish-brown, covered with a greyish-yellow, almost 

 golden pile ; head with an impressed line between the antennae ;
