as long as broad at base, reaching half-way across prosternixm ; maxillary palpi 

 long. Antennae 1'6 times as long as the head ; relative length of joints approxi- 

 mately.— 8 : 15 : 16 : 16-5 : 16 : 15 : 14 : 11. 



Prothorax strongly transverse, 2'25 times as broad across hind angles as 

 long; pi'othoracic setfE long, especially the pair at posterior angles, pointed. 

 Pterothorax slightly broader than prothorax, longer than broad. Wings light 

 greyish-brown, cilia dark ; fore-wing more markedly obscured from commence- 

 ment of the marginal ciliation to beyond the middle ; dark patch at base. 

 Hind margin of fore-wing with 3-9 cilia duplicated near apex. Fore-tarsus 

 with a minute tooth. Abdomen long, a little broader than the ptei-othorax. 

 Tube about O'G times the length of head, twice as long as broad at base, gently 

 narrowed apically with a slight and gradual constriction just before apex ; 

 apical bristles not quite as long as tube, dark basally but lighter apically. 

 Lateral abdominal bristles yellow ; moderately long, especially those on 

 segments 7 to 9. 



S . Prothorax a little longer than in the 9 , and fore-legs slightly incrassato 

 with each fore-tarsus fvirnished with a distinct tooth. 



This species is separated from both juncorum and aculeatus by the colora- 

 tion of the antennae, the clouded fore-wings, the relatively longer prothoracic 

 setae, and the shorter and more transverse prothorax. Prom juncorum it further 

 differs in its smaller size, the shorter head and relatively longer antennae, and 

 from aculeatus by its deeper coloration. Its habitat, too, is of a different 

 character. 



Type : In Hope Collections, University Museum, Oxford. 



Hah. : Amongst dead branches, old pea and bean-sticks, &c. 

 Several examples of both sexes at Hogley bog, near Cowley (Oxon) ; 

 one $ at Balsall Common, Warvpickshire, September, 1913. Also a 

 single $ by general sweeping, near Enslow Bridge (Oxon), 21.ix.l3. 

 Both Mr. A. H. Hamm and Mr. Willoughby Ellis have assisted me in 

 securing further examples after my discovery of the species. 



Haplothrips cephalotes, sp. n. 



Length abovxt 1'2 mm. 



General colour as in R. aculeatus, head deep blackish-brown ; antennae with 

 3rd joint yellowish-brown, and the 4th and 5th a lighter grey-brown (or yellow- 

 ish-grey-brown) than the following ; wings clear. 



Head about 1-6 times as long as the prothorax, and I'l times as long as 

 broad behind eyes. Cheeks gently rounded and converging strongly posteriorly, 

 minutely spinose ; vertex raised in form of hump with the anterior ocellus at 

 apex, facing forwards. Eyes rather prominent, coarsely facetted ; post-oc\ilar 

 bristles only moderately long Posterior ocelli almost touching inner margins of 

 eyes on a line drawn below their anterior third. Antennas set below vertex, 

 about 1-5 times as long as the head ; joint 3 distinctly shorter than 4, and
