350 TIPULLD.E. 



Macquart's remark that the metathorax is all yellow is probably 

 an error for nietanotum, which in one of the three specimens is 

 very conspicuously uniform lemon-yellow, in another bright lemon- 

 yellow with an orange hind border, and in the third orange with a 

 blackish lower margin. The scutellum also varies, being in two 

 specimens shining black, in the third shining brownish yellow. 

 Again the abdominal marks are very variable. The first example 

 has the basal segment black, a broad black band on hind margins of 

 the 2nd and 3rd segments, a narrow one on the 4th and 5th, the 

 6th being mainly blackish. In the second specimen the only 

 black is on the tips of the 2nd and 3rd segments, the whole of the 

 6th and the base of the 7th. In the third specimen the marks 

 are similar, but narrower, and rather less intense. The fore 

 femora have a broad blackish central band which is quite distinct 

 in one specimen, much less so in the second, the third having 

 these legs missing. This character has not been noted before. 

 In one specimen the pleurae are slightly marked with black, in 

 another they are entirely lemon-yellow, except for a rather large 

 pale orange spot below the wing-root. 



Macquart notes that the second posterior cell is nearly petiolate. 

 In two of the three examples before me it is quite distinctly so, 

 as much as in many species of Tipula in the third it is very 

 shortly, but still practically so, and slightly more in one wing than 

 the other. All these points prove the variability of the species in 

 many particulars, and the comparatively small size of the discal 

 cell, which is emphasized in the present specimens, is also a strong 

 specific character.

 black, or 1st joint yellow. Thorax : dorsum between the stripes 

 orange-yellow, the colour fading at the edges of the dorsum to paler

 towards the anterior margin. The dark marks on the prothorax

 outer stripes in front of them. Scutellum black or dark brown, 

 shining ; metanotum yellowish on upper half, with or without a 

 narrow dark median line, black on the lower half ; sides con-
