Originally de.<ciibeil from Barbados and subsequently recorded from Cuba. 

 Xicaragua, and Mexico by Crawford and from Porto Rico by the author, this species 

 is represented in the Australian material by a series of seven females taken by Mr. 

 Girault in Xorth Qvieensland. These specimens, which were collected at Aloomba, 

 July 7, 1912, at HaMfax, February 28, 1913, and at Ndson, April 2 and 4, 1913, 

 have been found indistinguishable from Neotropical and Nearctic specimens even 

 after a wireful .study of a large series of specimens cleared in potassium hydroxide. 

 In colour, form, and the multitudinous details of chitinous structure there is very 

 little variation indeed, and I have no hesitation in declaring that we are here con- 

 cerned with but a single species which, through the medium of commerce, has been 

 distributed to many parts of the world ; or which has persisted without mollification 

 in spite of complete geographic isolation. 



The insect frecjuents flowers of many s]iecies, and the student is referred to 

 the papers bj- FrankUn and Crawford for their enumeration. 



HAPLOTHRIPS VARIUS sp. nov. 



Fenmle (nmcropterous). — Length about 1-6 mm. Colour dark blackish bro'wn 

 with fore tarsi yellow and fore tibiie yellow apically ; antenna' brown, segments 1, 2, 

 and 5-8 darkest ; 3 slightly paler, particularly along outer surface and at base. 



Head slightly longer than wide, sides nearly straight ; vertex produced, the 

 anterior ocellus overhanging and slightly surpassing frontal costa ; po.stocular bristles 

 blunt, two-thirds as long as eyes. Eyes one-third as long as head, slightly wider 

 than their interval. Antennae of normal structure, segment 3 small, almost exactly 

 as in //. humilis (.see Proc. Biol. Soc. Wash., vol. xxvii, 1914, pi. iv, tig. 2), but with a 

 sense-cone on inner surface ; segment 4 large ; 7 and 8 rather closely united. 



Prothorax smooth ; all usual bristles present, blunt, the two pairs at posterior 

 angles longest, others subequal in length to postoculars. Wings of fore pair broad, 

 very much narrowed at middle, the scale and the region of the three subbasal bristles 

 brown, remainder colourless ; subbasal bristles approximate, equally blunt, forming 

 an almost equilateral triangle ; no accessory hairs. J<''ore tarsus with a minute tooth. 



Abdominal bristles mo.stly blunt : terminal bristles about 1-2 times the length 

 of tube.
