TIPULA. 309 



'hyaline part continued througli the cliscal and 1st posterior cells 

 to the wing-margin. A narrow, irregular clear streak trans- 

 •versely across the marginal cell, just beyond the barely obvious, 

 small blackish stigma, which clear streak joins the clear part of 

 the 1st basal cell. Veins brown, 3rd and 5th longitudinal veins, 

 and the posterior cross-vein coiuiecting the 5th with the discal celV^ 

 deeply but narrowly suffused with dark brown. Pedicle of fork of 

 upper branch of 4th vein nearly as long as discal cell. Halteres 

 brown. 



Length 15 millim. 



Described from two males and one female {types) in the Indian

-210. Tipula serricornis, sp. nov. 



S $ . Head mainly brownish yellow, including palpi and 

 antennae, the former distinctly brown ; the vertex much lio-hter 

 yellowish or yellowish grey, the frons being one-third the width 

 of the head. The 1st scapal joint long, 2nd quite short ; let 

 flagellar joint three-fourths as long as the 1st scapal joint, but 

 rather narrower, cylindrical, as is the scape; remainder of flagellar 

 joints subtriangular, one of the angles pointing downwards, so that 

 the upperside of the flagellum is practically level ; very short stiff 

 hairs along the dorsum of the flagellum, the joints below being 

 quite bare. The length of the antennae is distinctly less than 

 twice the length from the back of the head to the tip of the 

 proboscis. Nasus distinct, narrow, pointed. Thorcw. prouotum 

 rather well defined, brighter yellow than the rest of the thorax 

 which is brownish yellow, except the dorsum, this being occupied 

 by the usual three stripes and posterior pairs of spots, all of which 

 are contiguous to one another, greenish grey in colour, nearly 

 filling the dorsal surface. The colour extends to the scutellum and 

 metauotum, but is there a little lighter and more yellowish and 

 semi-translucent. A whitish band or streak is irregularly reflected 

 in certain lights on the pleurae from the pronotum to just below 

 the wing-roots, and a similar band at a short distance below the 

 upper one. Abdomen hvownhh yeWow, a short brown streak at 

 each side near the base ; two or three apical segments in the male 

 more or less blackish, the colour less conspicuous in the female 

 Genitalia inconspicuous, brownish yellow, not wider than the 

 abdomen; a small dorsal plate ending in two stout finger-like 

 appendages ; a large basal joint to the claspers, the 2nd join1} being 

 apparently in the form of two leaf-shaped organs ; a ventral plate 

 can be seen, completely withdrawn within tlie abdominal cavity. 

 In the female the genitalia reddish brown, shining ; two pairs of 

 stout valves, rather short. Legs uniformly brownish yellow 

 Wings yellowish or yellowish grey, stigma almost imperceptible •
