250 DIPTERA NEMATOCERA. 



Ehipidia pictipennis sp. n. (Plate 9, fig. 4.) 



Resembles R. rostrifera Edw. (Malay Peninsula and Suma- 

 tra), differing as follows : — First antenna! segment entirely 

 dark, contrasting with the pale yellow second segment. 

 Thorax with no trace of a dark median line. Wings with small 

 hyaline spots included in the centres of the four main dark costal 

 spots (see figiu^e). Subcostal cross vein absent. Vein M^ quite 

 free, not connected with either M^ or M^ (Cui). In the female 

 the segments of the antennal fiagellum are nearly globular and 

 without distinct necks, quite unlike those of most other species 

 of the genus. 



Mt. Penrissen, 4500 feet— 2 cf ; Mt. Dulit, 3000 feet— 19. 



Ehipidia griseipennis sp. n. (Plate 9, fig. 5.) 



9 . Head dark brownish. Eyes separated by about the 

 width of two or three facets. Antennae and palpi blackish, 

 structure normal. Thorax brownish, praescutal stripes darker 

 brown, not very sharply defined ; anterior half of median stripe 

 represented by three dark lines with lighter spaces between 

 them. 



Pleurae somewhat darker than the dorsum, hut not distinctly 

 striped. Abdomen rather dark brown, venter lighter except on 

 the posterior margins of the sternites. Legs rather light 

 brownish, femora dark brown except towards the base. 

 Wings as figured ; the greyish markings very extensive and 

 almost obliterating the lighter areas, especially in cells M and 

 Cu. Plaltercs ochreous, base of knob darker. 



Length of body 6 mm. ; wing G mm. 



Mt. Penrissen, 4500 feet— 1 cf (tvpe) ; Mt. Poi, 5200 feet— 



49. 



In wing-markings this most nearly resembles R. demarcata 

 (Brun.), but the thoracic ornamentation is quite different. 



Ehipidia discreta sp. n. (Plate 9, fig. 6.) 



9 . Eesembles R. griseipennis, differing as follows 1— 

 Middle stripe of praescutum with its anterior half entirely dark. 

 Legs somewhat darker, but the femora more extensively liglit 

 brownish towards the base. Wings with the ground colour 

 tinged with yellow, the spots darker brown and all distinctly 

 separate, cells M and Cu largely pale, as shown in figure. 



Length of body 10 mm. ; wing 10.5 mm. 



Mt. Murud, top~l 9 .
