Total length of antenna. 0-305 mm. 

 Described from six females and nine males, taken by sweeping, at Nelson, N.Q. 

 (type locality), April 2, 4, and 27, 1!»13 ; at Proserpine. X.Q., November 2 and 3. 1912 ; 

 at Quingilii. X.Q., September 13, 1912 ; and at Hincliinbrook Island, N.Q., July 19, 

 1912. 



The principal diagnostic characters are the colour of the legs and antennae, 

 the long third antennal .segment without a sense-cone on its inner surface, and the 

 well-develojjed anterior marginal bristles. 



HAPLOTHRIPS FROGGATTI sp. nov. 

 Fenmle (macro pterous). — Length abovit 1-4 mm. Colour dark blackish brown, 

 with fore tarsi j-ellow and fore tibist jellow apically ; antennae brown, segments 1, 2, 

 and 6-8 darkest ; 3 paler, particularh- along outer surface and at base. 



Head as broad as long, with sides very slightly arched ; vertex slightly pro- 

 duced, the anterior ocellus overhanging and usually just attaining frontal costa ; 

 postocular bristles blunt, a little more than half as long as eyes. Eyes nearly 0-4 as 

 long as head, narrower than their interval. Antennas of normal structure ; segment 

 3 small, almost exactly as in //. hmiiilis (see Proc. Biol. >Soc. Wash., vol. xxvii, 1914, 

 pi. iv, lig. 2). witiiout sense-cone on inner surface ; segment 4 large ; 7 and 8 rather 

 closelj' united. 



Prothorax smooth ; all usu d bristles j)resent, blunt, the two pairs at posterior 

 angles slightly the longest, others equal in length to postocidars. Wings of fore pair 

 broadened at base and distinctly narrowed at middle ; the scale and the region of the 

 three subbasal bristles brown, remainder colourless ; subbasal bristles equidistant, 

 arranged nearly on a straight line, the outer longest and less blunt ; about 10 accessory 

 hairs. I'bre tarsus unarmed. 



Abdominal bristles mostly blunt ; terminal bristles about 1-3 times as long 

 as tube. 



Measurements of holotypc : — length 1-43 mm. ; head, length 0-lSI nnn., width 

 0'18I mm. ; prothorax, length 0-132 mm., width (inclusive of coxse) 0-269 mm. ; 

 pterothorax, width 0-312 mm. ; abdomen, width 0-31S mm. ; tube, length 0-1 15 mm., 

 width at base 0-061 mm., at a])ex 0-033 nun.

Male (macro pterouf). — Length about 1-2 mm. Almost identical with female 

 in colour and structure ; fore tarsus with a stout, triangular tooth.

 pterothorax. width 0-288 mm. ; abdomen, width 0-270 mm. ; tube, length 0-1 15 mm., 

 width at base 0-054 mm., at ajwx 0-030 mm.
