Note.— Varies a good deal, and hence has been repeatedly redescribed 

 under various synonyms, some of which are distinguished by Mr. 

 Theobald as varieties as below : — 



Variety 1, salimis, Ficalbi. Posterior three-fourths of the seg- 

 ments speckled with hazel scales, anterior fourth white. 

 Variety 2, stricticus, Meigen. Basal bands absent, white lateral 



spots only remaining. 

 Variety 3, luteovittatiis. Basal bands yellowish, expanded in the 



middle, lateral spots whitish. 



Variety 4, detritus, Halliday. A small variety, with the small 



scaled, lateral basal patches of the mesonotum very prominent. 



Habitat. — Common throughout Europe, from Lapland to Italy, as 



a sylvan species. Ficalbi's salinus breeds in salt marshes, and the 



larvae of others are found in all sorts of fresh water and even in large 



lakes.

 colour very dark, and without any distinct colour markings in the

 curved scales, and three lines of black bristles, the middle one 

 of which ends in a bare space in front of the scutellum. Abdo-

 rather deeper in the middle, but expanding laterally into distinct
