NEW GENERA AND SPECIES OF AUSTRALIAN TIIYSANOPTEFA—HOOD. Ul 



EUOPLOTHRIPS BAGNALLI sp. nov. 

 Fenude (macropiermi^). — Length a)wut 2-2 mm. Colour dark blackish Ijiown 

 (nearly black), with fore tibia3 and tarsi and bases of intermediate antennnl segments 

 3-ellowish ; wings fuliginous, darker at base, and with a dark median line. 



Head l-()4 times as long as wide, broadest across eyes, cheeks nearly straight, 

 slightly converging posteriorly and strongly con.stricted at base, which is 0-73 of the 

 width across eyes ; dorsal and lateral surfaces nearly smooth, the transverse anasto- 

 mosing hnes faint, three or four minute bristles visible in profile ; vertex conically 

 produced ; postocular bristles blunt, about half as long as eye. Eyes large and 

 prominent, about O-Sfi as long as head and about three-fourths as wide as their interval. 

 Ocelli cquidi.stant, the anterior oceUus overhanging and on a line with the base of the 

 first antennal segment. Antennae of normal structure, formed as in Mesothrips. 

 l-£ tunes as long as head ; .sense-cone formula : 3, 1-2 ; 4, 2-2 ; 5, 1-1 +i; 6, l-l + i; 

 7 with one on dorsum near apex ; segments 1,2, 7, and 8 concolourous with head, 2 

 paler at apex ; 3 and 4 with pedicels yellow, the remainder of these segments dark 

 fuliginous, paler at apex ; 5 yellow in basal third, fuliginous beyond ; 6 fuliginous, 

 j)edicel paler. Mouth-cone shorter than its basal width, broadly rounded. 



Prothorax large, heavy, and 0-61 as long as head, the breadth across coxse 1-84 

 times the length and about 2-3 times the apical breadth ; ijronotum smooth, with 

 short median thickening ; all usual bristles present, anterior marginals greatly reduced, 

 the others blunt and about as long as postoculars. Fore legs slightly if at aU enlarged, 

 the fore femora with a long, straight acute tooth near middle of inner surface ; fore 

 tibiai, near middle of inner surface, with a finger-like projection two-fifths as long as 

 femoral tooth bearing a minute bristle at its tip ; fore tarsi with a long, hooked 

 tooth. Fore wings slightly narrowed at middle, with about ten accessory hairs on 

 posterior margin, and with the three subbasal bristles bhnit and equal in length to 

 postoculars : wings of both pairs pale fuliginous, darker at base and in apical half, 

 and with dark median streak extending to near apex of both pairs. 



Abdomen slender, much narrower than pterothorax, broadest across segment 

 2. Tube about 0-62 as long as head. All bristles long, pointed, yellowish, those at apex 

 of segment 9 nearly as long as tube ; terminal bristles brown, about equal in length 

 to tube. 



Measurements of holotype : — Length 2-16 mm. ; head, length 0'336 mm., width 

 across eyes 0-204 mm., at base 0-148 mm. ; prothorax, length 0-200 mm., width 

 (inclusive of cox*) 0-380 mm. ; pterothorax, width 0-372 mm. ; abdomen, width 

 0-332 mm. ; tube, length 0-208 mm., width at base 0-082 mm., at a^x-x 0-039 nnn. 



Antennal segments : 12 3 4 5 



Length (p) 60 63 83 89 81 



Width (p.) 46 35 46 45 36 



Total length of antenna, 0-542 mm. 



Described from one female taken by sweeping in jungle at Nelson, N.Q., 

 May, 30, 1912, by Mi-. A. A. Girault. 



Named after Richard 8. Bagnall, Esq., of Penshaw, England, in recognition of 

 his work on the Thj^sanoptera and in appreciation of his many courtesies to the
