scarcely sinuously to about the middle, where they are feebly 

 rounded, and whence they converge bisinuately to the front ; its 

 surface is very finely and sparsely punctured, the front portion 

 depressed ; there is an interrupted and rather feeble channel 

 down the middle of the hinder lialf ; the base is very gently 

 arched hindward ; scutellum smooth behind, punctured in front. 

 The elytra are closely, evenly, and rather finely punctulate, and 

 bear (besides the raised suture) distinct traces of three or four 

 cost?e, which almost reach the apex. The metasternum is faintly 

 punctulate, and bears a short, close, erect pile ; the ventral seg- 

 ments are nitid, glabrous, and almost laivigate. 



The bright red head, dark red-brown shining prothorax, and 

 testaceous semi-opaque elytra, with their apex black, will render 

 this species easy to recognise. 



Allied to Z. tricolor, LeG., but (apart from colour) difi'ering in 

 its much shorter head, difierently shaped clypeus and labrum, 

 prothorax very much narrower in front, kc. 



Port Lincoln ; taken by Mr. J. Anderson, 



Z. brevicornis, sp. nov. Rufa ; antennis, palpis, mandibulis aj^ice, 



femoribus anticis antice in medio, tibiis (basi exceptis), tarsis, 



macula in capite, maculis in prothorace 2, metasterno (epis- 



ternis exceptis) et abdominis parte, piceo-nigris ; elytris 



coeruleis, creljre subtilius (postice crassius) punctulatis ; 



capite antice minus producto ; prothorace antice minus 



angustato. Long., 5 1. ; lat, 14-1. 



The antennae are about half as long as the whole body ; joint 



1 is short (scarcely as loiig as half the distance from eye to 



eye); 2, shorter still; 3 and -i subequal, each of them equal to 



the basal joint. The head is not very triangular in shape, its 



length and breadth al3out equal, its length a little greater than 



that of the basal four antennal joints together. The labrum is 



scarcely so long as the clypeus (the two together not quite half as 



long as the rest of the head), its surface devoid of a dorsal furrow, 



strongly punctulate, its front ciliated. The clypeus is strongly 



punctulate, its hind suture strongly arched. The surface of the 



hind part of the head is punctulate strongly in front, and gradually 



less strongly hindward, and bears between the eyes a large piceous 



blotch, which is slightly protuberant and lajvigate in the middle ; 



the liind margin of the head is almost truncate. The prothorax 



is very slightly shorter than the head, very slightly wider than 



long, and equal in width to the hind margin of the head ; its 



front margin (which is emarginate) is nearly half as wide as its 



base ; its sides are gently and somewhat evenly arched, their 



greatest divergence being in front of the middle ; its surface is 



strongly and very sparingly punctured, with some feeble indica-
