Notes.— The peculiar formation of the antennae in this genus 

 immediately distinguishes it from all others known from the East. 

 There is a resemblance in the antennal appendages to Westwood's 

 illustration of Ozodicera gracilis,^ Westw., but that genus belongs 

 to the subfamily Tipulinae. 



Ceratostephanus antennatus, mihi, sp. nov. 

 a' . Western Himalayas. Long. 4 mm- 



Head. — Back of head blackish, with a few bristles. Owing 

 to the construction of the eyes, which are absolutely contiguous 

 from the vertex downwards, there is no frons, but a row of 

 irregular-sized bristles set between the eyes shows the only line of 

 demarcation between them. Proboscis brown, palpi dark brown, 

 pubescent, first joint the shortest, the others comparatively 

 long. Antennae : ist scapal joint elongate, broader at tip, 2nd 

 enlarged considerably, oval, both with stiff hairs. The flagellum 

 is of twelve elongated cylindrical pale yellow joints, with a pair 

 of strong long diverging bristles on the upper side just beyond the 

 base. On the under side at about the same place are two dark 

 brown elongate palp-like processes, very conspicuous, pendant and 

 of considerable size, with whitish pubescence. 



Thorax brownish, darker on the dorsum ; scutellum and 

 metanotum of similar colour. 



Abdomen brownish yellow, sides of abdomen and posterior 

 margins of segments distinctly blackish ; belly similar. Genitalia 

 consisting of a pair of large linear fleshy claspers of two joints of 

 equal length and size, below which is a horny narrow elongate 

 style, apparently immovable. 



Legs brownish yellow ; tips of femora and tarsi barely 

 darker. 



Wings. — -Venation as in typical Limnobia, except that the 

 auxiliary vein ends just above the origin of the second longitudi- 

 nal vein, with the subcostal cross-vein at its tip. Colour of wing 

 almost clear, with very numerous very small pale grey spots and 

 short streaks covering the surface. A very slightly darker grey, 

 just sufficient to be perceptible, over the cross-veins, the origin of 

 the 2nd vein, tip of ist vein, tip of 7th vein, and at two places 

 on the costa, the first nearly basal, the second opposite the tip of 

 the 7th vein. In all the darker grey spots along the costa the ist 

 longitudinal vein is black. 



In the rest of the wing the veins are generally brownish, but 

 here and there for a short distance they are sometimes pale yellow, 

 sometimes black. Halteres pale yellowish, clubs barely darker. 



Described from a single & from Simla, 24-iv-07 [^Annandalel.
