segments 1 and 2 about coucolourous with head, 2 yellow at apex ; 3-6 lemon yellow, 

 6 iiifuscate in apical half ; 7 and 8 blackish brown. Mouth-cone broadly rounded, 

 attaining apical fourth of prosternum. 



Prothorax about 0-54 as long as head and (inclusive of coxse) about 2-7 times 

 as wide as median dorsal length ; surface smooth, with short median thickening ; all 

 usual bristles present, pointed, the outer posterior jjair longer than postoculais, the 

 inner posterior pair about equal in length to postoculars, other bristles less than half 

 as long. Wings long, broad, fore pair with about seventeen accessory hairs on posterior 

 margin and with the three subbasal bristles of the same size as postoculars ; liind 

 wings clouded along margins and with a dark median line. Fore tarsus unarmed. 



Abdoiuen of normal form and structure. Tube about equal in length to head. 

 Abdominal bristles long, pointed, dark brown in colour, those on segment 9 longer than 

 tube.

Described from three females taken by sweeping in jungle at Nelson, X.Q., 

 May 25, 1913, by Mr. A. A. Girault. 



A true Liothrips, easily known by the long tube and the colouration of the 

 wings and antennae. 



LIOTHRIPS TENUIS sp. nov. 



Female (niacropterous). — Lengtli about 2-7 mm. Colour dark blackish broT\ii 

 (almost black), with tarsi, apex and inner surface of fore tibiae, and mo.st of antennal 

 segments 3-6, lemon yellow ; fore wings darkly infuscate, particularly at base and 

 along median line. 



Head 1"8 times as long as wide, nearly smooth ; cheeks nearly parallel, con- 

 stricted near base ; vertex not produced ; postocular bristles sUghtly longer than 

 eyes, nearly pointed. Eyes about one-tliird as long as head, flattened at sides, pro- 

 truding at posterior angles, slightly narrower than their interval. Ocelli ecpial in size 

 and equidistant, the anterior ocellus directed upward and not overhanging. Antenna} 

 of normal structure, nearly 1-5 times as long as head ; segments 7 and 8 more closely 

 united than the others but not compactly joined ; sense-cones arranged as usual in 

 the genus ; segments 1,2,7, and 8 concolourous with head, 2 slightly paler at apex ; 

 3-6 lemon yellow, 4 and 5 lightly infuscate at apex, 6 dark browai in ajiical two-fifths. 

 Mouth-cone broadly rounded, reaching about halt across prosternum. 



Prothorax about 0-4 as long as head ; surface roughened, and with short 

 median thickening ; all usual bristles present, nearly pointed, dark brown in colour, 

 the two posterior pairs longest but decidedly shorter than postoculars, the others
