374 TIPULID.I. 



quite colourless at base, and slightly but distinctly infuscated at 

 tips ; an oval, rather large and distinct brown stigma at tip of 

 2nd longitudinal vein. The 2nd longitudinal vein originates 

 beyond middle of wing ; the 3rd begins just before middle of 

 2nd, so that the veins appear crowded towards the tip of the 

 wing. Halteres pale with black knobs. 



Length 4 millim. 



Kedescribed from four males and one female in the Indian 

 Museum from Nedumangad, Travancore State, South India, 

 14. xi. 09 (Annandale). The species is also known from Java 

 and the Philippines, and is most probably generally distributed 

 throughout the East. 



Type. The location of this is unknown, and the probability is 

 that it is entirely lost. 



It seems to me that the Limnobia apicalis of Wiedemann is 

 probably identical with one of the more recently described species 

 with white tarsi, or else with D. saltans, Dol. If so, the name 

 will take precedence of all others. Mr. Edwards * calls the 

 species saltens instead of saltans (the former being the name 

 given by Doleschall), and places it in Thrypticomyia, Skuse, 

 but the stability of this latter genus appears doubtful, and the 

 emendation of DoleschalPs name seems legitimised by long usage.

" Head t : antenn* brownish, slightly longer than thorax ; 14- 

 jointed, last joint with the apical joint narrower, so that it has 

 the appearance of being divided. Joints of flagellum strikingly 

 pedicillate, the glabrous pedicels occupying from one-third to 

 one-half the length of the joint, and being only one-quarter as 

 broad as the broadest part ; broad portion more or less conical, 

 the apex of the cone being towards the base of the joint ; these 

 broad portions are provided with a verticel of fine hairs, three or 

 four shorter bristles and one longer dorsal bristle, the hairs being 

 two-thirds, the shorter bristles about one and a half and the longer 

 about two and a half times as long as the breadth of the conical 

 portion of the joint. Thorax ochreous, mesonotum with a rather 

 broad dark brown central stripe reaching back to the suture. 

 Abdomen only slightly constricted at base, brown, apical segments

t The order of placing the descriptions of the yarious parts of the body is 

 slightly altered for the sake of uniformity with the remainder of the present 

 work.
