214 Mr. R. S. Bagnall on new Thysanoptera. 



as long and 1*5 as broad as head; with a well-developed 

 accessory seta at each hind angle. Fore-tarsi (in male) 

 unarmed. Wings broad, with side3 subparallel. Tube 

 basally, in male, only shallowly and broadly einarginate. 

 Abdomen only moderately heavy. 



This genus is separated from Rhynchothrips by the last 

 and penultimate antennal joints not being short and closely 

 united, the convergent cheeks, the stouter mouth-cone, and 

 the shorter and transverse prothorax and more slender build. 



It should be here noted that the two Trichothripid species, 

 (Edemothrips brevicollis, Bagn., from Japan, and (Edemothrips 

 propinquus, Bagn.* (Australia), both described from female 

 examples, may be referable, on the discovery of the respective 

 males, to other genera. 



Type. Eurhynchothrips convergens, mihi. 



Eurhynchothrtps convergens, sp. n. 



£ . — Length about l"8mm., breadth of rnesothorax0"37mm. 



Colour chestnut-brown ; tube lighter in distal half; fore- 

 tibia? yellow, lightly shaded with brown on the outer margin 

 and near the base within ; all tarsi yellowish. Antenna? with 

 segment 1 brown, 2 brown shading to yellow, 3 to 6 yellow, 

 3 pale, 4 and 5 tinged lightly with brown distally, 6 with 

 distal half or thereabouts brownish, and 7 and 8 wholly light 

 brown. Wings clear, scale of fore-wing brown, cilia dusky. 



Head a little more than 0"8 as long as broad immediately 

 behind eyes ; cheeks faintly rounded, converging posteriorly, 

 about 0*85 as broad at neck as behind eyes. Eyes broadly 

 rounded, occupying in their greatest dorsal length approxi- 

 mately 0*4 the length of the head; space between them about 

 0"4 the greatest width of the head. Vertex not produced, 

 ocelli large, posterior pair above a line drawn through centre 

 of eves and contiguous to their inner margins, anterior 

 ocellus forwardly directed. Antenna? twice or a little more 

 than twice as long as the head, set below the vertex with the 

 basal joints subapproximate ; joint 4 broader than 3 or any 

 of the others. Relative lengths of joints 3 to 8 : — 20 : 22 : 

 20 : 23 : 22 : 16 ; 3 claviform, 4 and 5 broad and roundly 

 claviform, 6 to 8 narrower, elongated. One stout sense-cone 

 on outer side of segment 3, 1 + 2 similarly stout cones on 4, 



* This must not be confused wiili Trichotkrips propinguus, Bagn., an 

 English species.
