sutural thickened and out-turned, subgranulate at base; second 

 with four; third with about ten, elongate tubercles from base to 

 middle, more separate and feebly conical posteriorly to middle; 

 fourth with one or two; fifth and sixth each with a row of small 

 rounded tubercles, placed fairly close together, but not con- 

 tiguous, about twenty in each row. Sides with tubercles hardly 

 raised above general surface. Beneath gently convex; fifth seg- 

 ment with a shallow, median, linear impression from base to 

 apex, widening out into a shallow, ill-defined depression at apex. 

 Dimensions : 2, 25 x 10 mm. 



Hah. — South Australia. 



Described from one of two female specimens in the Australian 

 Museum. It is hard to be certain if either of these specimens

(J. Elongate, subparallel. Black; clothing sparse, yellowish, 

 head with two brownish patches separating the supraorbital and 

 median vittse, median vitta divided into two, and extending on 

 to the sublateral rostral sulci; ventral segments with a median 

 golden macule, and a lighter lateral one. 



Rostrum rather narrow across the dorsum; median carina pro- 

 minent, rather broad; sublateral sulci narrow, extending back, 

 somewhat, onto head. Head not separated from rostrum above, 

 with three Isevigate lines continuous with the rostral carinse, a 

 small fovea present in middle line at junction with rostrum. 

 Prothorax (4-5 x 5-5 mm.) with apical margin feebly rounded, 

 almost truncate above, and with rather prominent ocular lobes; 

 median line not impressed; moderately closely set with rounded, 

 somewhat depressed, granules, somewhat variable in size. Sides 

 sparingly granulate. Elytra (11*5 x 6-5 mm.) long, almost par- 

 allel-sided; base slightly emarginate, humeral angles not pro- 

 duced; with strise of very shallow foveiform punctures; first 

 interstice subcostate, little prominent, tending to split up into
