vein. Tip of wing above 4th vein, a small oblong spot (distinct 

 but ill-defined) about the middle of the anal cell, and an irregular 

 suffusion before the posterior cross-vein (which suffusion con- 

 tinues along the 5th vein to the margin of the wing), blackish. 

 A clear streak over the 3rd vein extending forwards a little, and 

 posteriorly to the inner side of the discal cell. Halteres blackish. 



Length : tf 22 milliin. (including proboscis) ; $ 34 inillim. (in- 

 cluding proboscis and ovipositor). 



Described from a unique male and female taken by Dr. Annan-

207. Tipula dives, sp. nov. 



<5 . Head : frons and back of head blackish grey. Proboscis 

 brown, a little yellowish below; palpi brown. Antennae con- 

 spicuous ; the scape and basal joints of the flagellum brownish 

 yellow, remainder of flagellum dark brown ; 1st scapal joint long, 

 2nd very short ; 1st and 2nd flagellar joints cylindrical, 2nd rather 

 shorter ; remaining joints with their uppersides quite linear, the 

 underside of each almost semicircular, giving a distinct serrated 

 appearance. Thorax : dorsum rich dark olive-brown, the colour 

 having a velvety appearance towards the margins and extending 

 over the anterior margin, covering the prothorax. The usual 

 three stripes (the median one distinctly divided) obvious but 

 suppressed, rather dark greenish grey in colour. Behind the 

 suture on each side are two similarly coloured spots, nearly con- 

 tiguous, the first smaller and triangular, the hinder one nearly 

 oblong ; a small, almost bluish triangular mark behind the middle 

 of the mesonotal suture ; sides of thorax bright yellow ; a dark 

 brown line from the neck to below the base of the wing. Scu- 

 tellurn and metanotum concolorous with the ground-colour of the 

 thorax ; metanotum with greyish reflections. Abdomen blackish, 

 with microscopic golden pubescence; dorsum of 1st segment 

 rather broader, dark yellowish brown. Belly mainly black, but 

 the base of the abdomen both at sides and on belly yellowish. 

 Grenital organs robust, consisting of an upper oblong plate, brown 

 (blackish in middle), bifid posteriorly ; a pair of large bright 

 golden-brown claspers, minutely pubescent, the 2nd joint of which 

 is comparatively small, conical, and nearly bare ; the basal joint of 

 these claspers is very distinctly keeled on the underside, and 

 there appears to be no ventral plate. The claspers in the unique 

 example present are closely folded, so that no smaller appendages 

 are visible. Legs brownish yellow ; the upperside of the femora 

 distinctly blackish ; tips of femora with a moderately broad black 

 ring ; tips of tibiae and of each tarsal joint less conspicuously 

 blackish. Wings uniformly moderately deep brownish yellow; 

 the posterior cells and the whole wing posterior to the 5th vein,
