and among8t dead seeds of linrstu'ia spinoaa (A. K. Shaw & 



ft. Kelly). Warburton, Victoria, on Senecio vtllexoidee, 

 Leptoapermea acoparium, and Laurestinua sp. (/.'. Kelly). 



Distinguished from H.fultginoaua (Schille) by its larger 



size, deeper coloration, shorter head, etc. The postocular 

 and pronotal sette and those on the wing-scale are pointed in 

 fuligtnosus and are more slender than in viclorienaia. 



b. Form heavy, wings clear, broad basally and dislally, 

 without duplicated cilia, llab. Australia. 



Haplothripa robustus, sp. n. 



? . — Length 1*6 mm. ; breadth of mesothorax 038 mm. 

 Colour brown, head, thorax, and end of abdomen darker j 



fore-tibia? shaded yellowish distally and fore-tarsi yellowish. 

 Antenna) segments 1, 2, and 5 to 6 uniform dark grey-brown, 

 4 lighter brown, and 3 yellowish. Wings clear excepting 

 for a light brownish patch at base. Hypodermal pigmenta- 

 tion heavy. 



Head scarcely perceptibly longer than broad at base 

 (where it is broadest), cheeks straight, widening posteriorly, 

 though this may be exaggerated by pressure in mounting ; 

 vertex produced in the form of a hump, more pronounced 

 than usual, upon the apex of which the overhanging anterior 

 ocellus is seated. Postocular bristles short, blunt. Antennae 

 about To* times as long as the head, segment 4 broader than 

 either 3 or 5 ; relative lengths of segments 3 to 8 approxi- 

 mately as follows : — 50 : 55 : 48 : 45 : 44 : 33. In one 

 example segment 6 is longer (49 instead of 45) and at least 

 half the suture between 7 aud 8 is fused. 



Prothorax 0'65 the length of the head and about twice as 

 broad as long; setae moderately long, blunt, colourless; the 

 one at each posterior angle the longest, about 0*45 the length 

 of the prouotum. Fore-tarsus armed with a minute tooth ; 

 fore-femora slightly incrassate. Wings broad, the fore pair 

 being curiously broadened just beyond basal scale and again, 

 but neither so strongly nor suddenly, bejond median con- 

 striction. Abdomen very slightly broader than ptero thorax.
