322 Mr. R. S. Bagiiall on new 2'hysanoptera. 



Family Phlceothripidae. 

 Docessissophothrips laliceps, sp. n. 



(J. — Length 3*0 mm. 



Apterous. 



Colour dark reddish-brown ; fore-tlbiEe and all tarsi 

 yellowish. 



Head much as in D. ampliceps, Bagn., smooth and shining, 

 about l'2o times as long as broad, and viewed laterally only 

 weakly arched compared with ampliceps and other species of 

 tlie genus. Eyes small and finely facetted, occupying about 

 0'2 length of head ; ocelli small and widely spaced, a long 

 biistle behind eacli posterior ocellus; two pairs of long post- 

 ocular bristles, the outer pair being the longer. Genal 

 spinelets few. 



Antennae black, about twice the length of head, joints 2-4 

 yellowish, 3 grey-brown at apex, and 4 shading to brown 

 apically ; 3—5 clavate. 



Prothorax strongly transverse, about 2'5 as broad as long 

 and 0'4 tlie length of head, all sette long, at least those on 

 hind margin as long as the prothorax. Pterothoiax transverse. 

 Legs long, fore-femora not very stout, with long setse at 

 outer edge near middle, all tibise with long setae near knee, 

 fore-tarsus with tooth. Abdomen broad, with segments 

 strongly transverse, laterally with reddish patches as far as 

 segment 7 ; 8 rounded sharply to 9, 9 only slightly nar- 

 rowed. Tube long and stout basal ly, 1*22 times tiie length 

 of head, narrowed to distal half, with a weak constriction 

 before apex ; surface smooth, but with a scale-like sculpturing, 

 almost aciculate ; apical hairs rather short, dark, only about 

 035 the length of the tube, those on 9 about 0"7 as long as 

 the tube, those on 6 and 7 longer than on 9, and on 8 shorter. 



Of the described species, D. ampliceps, Bagn. (Central 

 America), D. monstrosus, Bagn. (New Caledonia), D. mojuVj 

 Bagn. (no data), and Z^.//-y/<^a^/.<;, Bagn. (Japan), this S2)ecies 

 can only be compared with ampliceps, and is separated by its 

 broader and (viewed laterally) less strongly arched head, the 

 three pairs of long cephalic bristles, the longer setaj on fore- 

 margin of prothorax, etc. It is the least extreme species of 

 the genus, whilst monstrosus is t!ie most extreme. Only a 

 single examjile is known of each of these striking species, 

 which would seem to suggest extreme rarity or, perhaps, 

 specialized habitat; the fact that Mr. Bryant found the
