TABANID/E. 



129. Hccmatopota pluvialis, L., Inchnadamph (Verrall) — not met 



with by me ; Invershin, 13th August 1900. 



130. H. crassicornis, Wahlb., Lochinver, 8th July 191 1; Loch 



Assynt, 8th June and 19th July 191 1; Inchnadamph 

 (Verrall). This species was flying round me in countless 

 numbers during the few hot days of early July, and was a 

 terrible pest ; the following occasions may be particularly 

 cited, viz. — Kirkaig Valley, 12th July 191 1; shores of 

 Glencanisp Loch, nth and 13th July 191 1. 



131. Tabanus {Therioplectes) montanus, Mg., Lochinver, 1st to 



16th July 191 1, in great numbers; Kylesku, 5th July 191 1; 

 Loch Assynt, 19th July 191 1; Invershin, 19th July 191 1. 

 Verrall records it from Invershin and Sheil House, Ross. 

 This species was unpleasantly in evidence during early July 

 in the valley of the Inver ; it was comparatively rare at 

 Inchnadamph. The variation in the marking on the eyes of 

 this species is worthy of note. Some have three distinct 

 bands, others have either the upper or the lower band, or 

 both bands faint and indistinct, and sometimes quite absent. 



132. T. (Therioplectes) tropicus, Mg., The Mound (Verrall). 



133. T. {Therioplectes) luridus, Fallen., Golspie, 9th June 1904.
