TIPULA. 309 



hyaline part continued through the discal 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 oth longitudinal veins, 

 and the posterior cross-vein connecting the 5th with the discal cell, 

 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 

 Museum collection from Ukhrul, Manipur State, 6400 ft., taken 

 by the Kev. W. Pettigrew in August 1908 ; also from a cotype 

 female from Central China in the Vienna Museum. 



210. Tipula serricornis, sp. nov. 



c? 5 . Head mainly brownish yellow, including palpi and 



antennae, the former distinctly brown; the vertex much lighter. 



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



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



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. Thorav: pronotum 



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 



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



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



in certain lights on the pleura? from the pronotum to just below 



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



upper one. Abdomen brownish yellow ; 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 joint being 



apparently in the form of two leaf-shaped oi'gans ; a ventral plate 



can be seen, completely withdrawn within the 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 ;
