LIOTHRIPS CONNATUS sp. nov. 



Fenuile (macropterouc). — Length about 1-6 mm. Colour dark blackish brown, 

 with tarsi, distal ends of all tibiae, and at least the basal portion of antennal segments 

 3-6, lemon yellow ; wings almost clear, lightly infuscate at base. 



Head about 1-2 times as long as wide, entire dorsal surface rather deeply and 

 distinctly reticulate with anastomosing lines ; cheeks evenly rounded to eyes and to 

 base ; vertex .slightly produced ; postocular bristles blunt, slightly longer than eyes. 

 Ej'es slightly more than one-third as long as head, slightly if at all protruding, distinctly 

 narrower than their interval. Anterior ocellus overhanging and directed forward. 

 Antennae of nearly normal structure, about one and three-fourths times as long as 

 head, .segments 7 and 8 compactly united to form a single mass, 8 short, about 1-4 

 times as long as wide ; sense-cones disposed as usual in the genus ; segments 1, 2, 7, 

 and 8 conoolourous with head, 2 paler at apex ; 3-6 lemon yellow, 4 infuscate in distal 

 third, 5 in distal half, and 6 in distal three-fifths. Mouth-cone broadly rounded, 

 attaining middle of presternum. 



Prothorax two-thirds as long as head and (inclusive of coxaj) about 2-1 tijiies 

 as wide as long ; pronotum lightly reticulate with anastomosing lines, except at middle, 

 and with short median thickening ; all usual bristles present, cajiitate, the two 

 posterior pairs longest and about equal to postoculars ; mid-laterals slightly shorter ; 

 the two anterior pairs about half the length of postoculars. Wings long, broad ; fore 

 j)air with seven accessory hairs on posterior margin and with the three subbasal 

 bristles capitate, equal, and about the size of anterior laterals. Fore tarsus with a 

 long, stout, .slightlj' hooked tooth. 



Abdomen of normal form and structure. Tube about 0-73 as long as head, 

 sides straight, slightly constricted at apex ; abdominal bristles long, pale, capitate, 

 those on segment 9 nearly as long as tube.
