slightly swollen at the base ; all flagellar joints except the 

 first and last with two moderately long hairs above, none 

 below. Thorax brownish ochreous ; the prsescutum with 

 three darker brown stripes, without dark borders, the middle 

 stripe divided posteriorly by a pale line. Scutal lobes each 

 with two separate dark brown spots. Scutellum and post- 

 notum with a dark brown median stripe, most conspicuous 

 when viewed from in front. Abdomen brown with rather 

 obscure darker brown median and lateral longitudinal 

 stripes ; apical corners of tergites pale. Ninth tergite very 

 long, longer than the anal valves, these of the normal form, 

 flattened, pointed, only slightly enlarged at tlie base, without 

 distirjct outer keels. Genital valves well-developed, just 

 reaching base of anal valves. Wings as in PI. X. fig. 17 ; note 

 the rather long fusion of Cui and M3. Halteres ochreous, 

 base of knob blackish. 



Length of body 13 mm. ; wing 14 mm.

I have not been able to trace a previous description of 

 this species. The wing-markings are very similar to those 

 of T. quasimarmoratipennis, Brun., which evidently belongs 

 to the same group.

The female agrees closely with a female in the British 

 Museum from Trincomali, Ceylon (Lt.-Col. Yerbury), and 

 also with Brunetti's rather imperfect description; the species 

 is one of a group which is rather numerous in the Oriental 

 region, distinguished by the unicolorous wings and very 

 narrow axillary cell. T. demarcata is distinguished from 

 the other species known to me by the grey thoracic pleurae, 

 contrasting noticeably with the brown dorsum. Other 

 nearly allied species are T. sulaica, Walk., T. vilis, Walk., 

 T. walkeri, Brun. {fulvipennis, Walk.), T. gedehicola, Alex., 

 T. kuriuchieusis, Edw., etc. Some of these show good 

 specific distinctions in the antennse. 



It may be noted here that Brunetti's Pachyrhina demarcata 

 is also a Tipula, and requires renaming. I suggest Tipula 

 sessilis, nom. nov., basing the name on a male and female 

 in the British Museum from the Nilgiri Hills, 6700 ft., 

 8. xii. 1887 {Sir G. F. Hampson).
