the Tipulid genus Styringomyia. 217 



the genitalia, are quite sufficient for the identification of 

 this species, so that it is unnecessary to redescribe it. 



Brunetti (1912) figures the hypopygium of this species. 

 His figure is not very accurate, but contrary to my previous 

 statement (1913) it evidently represents the true S. ceylonica 

 in dorsal view, as correctly stated by him; moreover, it 

 does not resemble that of S. didyma. However, although 

 Brunetti's figure does represent this species, his elaborate 

 redescription has proved to have been based on a mixed 

 series, consisting probably of four species.

 nate. I have confirmed the identification of all the above- 

 mentioned specimens; in none of them was there any 

 noticeable variation from the Ceylon type.

Figs. 23, 60, 61, 62 and 63. 

 Head brownish yellow with some darker patches and indications 

 of a more yellowish median line. First joint of antennae yellow, 

 brown beneath, second brown, rest yellow. Thorax brownish- 

 yellow with rather indistinct darker markings consisting of four 

 longitudinal lines, the outer pair being near but not at the margin 

 of the mesonotum. Pronotum, scutellum and postnotum are as 

 usual brown at the sides, yellow in the middle. Abdomen of male 

 yellowish, with a broad, continuous median dark stripe which 

 broadens out somewhat in the middle of each segment ; hind margins 

 of the segments darker brown; ninth tergite dark brown, rest of 

 hypopygium yellow. In the female, even when the abdomen is not 

 discoloured, the median dark stripe is much less distinct. Legs 

 yellow; the rings narrow, incomplete ventrally and sometimes 

 rather indistinct ; on the hind tibiae the median ring may be absent 

 altogether. Joints of tarsi of fore and mid legs slightly darker at 

 their tips, those of hind legs scarcely perceptibly so. Wings with 

 the veins yellow, except the ascending portion of Cuj, which is 

 mainly black ; a small black spot over the R-M cross-vein not extend- 

 ing into cell R2 + 3 5 other black spots as usual at the junction of
