504 MR. R. S. BAGNALL ON A COLLECTION OF 



Family Phlceothripid^ (s. L). 

 Genus Craniothrips, nov. 



Size small. Head twice as long as broad, arched dorsally. Mouth-cone 

 not reaching across prosternum, blunt, rounded at tip ; maxillary palpi long 

 and stout. Prothoracic setse stout, blunt ; the single long bristle on each 

 fore-coxa pointed. Fore-wings slightly constricted at about middle. 



Belongs to the Haplotlirips-Hindsiana group, but distinguished at once by 

 the shape o£ the head, which reminds one in a modest w^ay of the arched head 

 of that curious genus DocessissopJiothrips, Bagn. 



Type. C. uriclii, mihi. 



Craniothrips urichi, sp. n. 



Length 1*8-1"9 mm. 



General colour lemon-yellow to a richer yellow ; antennal joints 5-8 grey- 

 brown, and distal half of 4 lightly tinged with grey ; lower median margin 

 of mesonotum and corresponding upper portion of metanotum and the whole 

 of the tube grey-brown. Wings clear, wdth a grey-brown patch at bnse; 

 fore-wing with the second third (i. e. middle portion) grey-brown, and hind- 

 wing with corresponding portion slightly tinged with grey ; cilia dark. Tip 

 of mouth-cone and a spot at tip of each tarsus brown. 



Head twice as long as broad across eyes and 1"5 times as long as the 

 prothorax, dorsal surface arched and sides somewhat constricted near base. 

 Eyes coarsely facetted, occupying approximately 0*25 the length of head, 

 pigmentation deep black. Vertex raised in form of a hump ; ocelli large, 

 posterior pair on sides of raised part, almost contiguous with eyes and above 

 a line drawn across their centre ; the anterior one facing forwards ; pigmen- 

 tation crimson. Interocular bristles absent. Postocular bristles present, 

 placed well back and about the length of an eye, stout, practically parallel- 

 sided and broadened at tip. Mouth-cone reaching about 0-7 across pro- 

 sternum, blunt; tip rounded. Maxillary palpi long and stout, basal joint 

 very short; one sensory filament at tip longer than the others and than the 

 palp, an additional filament on the inner margin near apex. Antennse at 

 least 1*6 times the length of the head, approximate at base and seated 

 below the vertex ; relative length of joints:— 12 : 19 : 21 : 21 : 20 : 29 : 18 : 14. 

 Sense-cones normal ; last joint with an apical sense-bristle as long as 

 the joint. 



Prothorax about 1*25 times as broad across hind-angles as long, diverging 

 from base of head to about middle and thence practically parallel. Bristles 

 at anterior and posterior angles and postero-marginal and mid-lateral pairs 

 present, each of the latter pair being set just behind and close to the ones 

 at anterior angles ; those at posterior margin about 0"5 as long as the
