1 88 NEW GENERA AND SPECIES OF THYSANOPTERA 



Macrothrips papuensis Bagnall* (PL VI., fig. 4). 



Through the kindness of Prof. Bouvier, Paris, I have had 

 the pleasure of examining a small collection of Thysanoptera 

 containing two examples of this species, which was un- 

 fortunately described from an incomplete specimen. The 

 moiith-cone is longer than the breadth at base and ends in a 

 blunt point. The basal joint of maxillary palpus is rather 

 long ("07 mm.), whilst the second joint is comparatively stout 

 and only a little more than twice the length of the first joint 

 (•15 mm.), and is tipped with one long and two shorter 

 filaments. 



The tube is three times the length of the ninth abdominal 

 segment, whilst the hairs of the latter are extremely long 

 (i'68 mm.), being one and three-quarter times the length of 

 the tube ('96 mm.). 



In a specimen of recent capture the tooth of the fore-femur 

 is protected by a number of short stout spines.

 Museum. 



Macrothrips intermedia sp. n. 



Length 10 mm.; breadth of mesothorax about 2*0 mm. 



Intermediate between M. papuensis Bagnall, and M. dubia 

 Bagnall, very closely resembling the first-named in general form. 

 The head is shorter, stouter, and more depressed than in M. 

 papitensis, being less than twice as long as broad ; the post- 

 ocular protuberance is obsolete; the spines are shorter and 

 stouter ; the ocelli are much smaller, and the posterior pair is 

 placed above a line drawn across the anterior margin of eyes. 



The. prothoi'ax is less distinctly channeled; the fore-coxal 

 projection is only slightly curved forward and not geniculate 

 or elbowed. Each fore-femur (smaller than in Af. papuensis, 

 but much larger, comparatively, than in M. dubia) is not so 

 profusely covered with long hairs, but has the same strong,
