SCIOMYZID.E. 



492. Dichrochira glabricula, Fall., Loch Assynt, nth June and 20th 



July 191 1. On the first of these two dates two specimens were 

 taken running about on boulders in the bed of the Tarragii 

 River, when their strange shape and quaint gait at once 

 attracted attention ; while on the second occasion two 

 specimens were swept off a yellow flower abounding on the 

 limestone rocks (Mountain Saxifrage, sp. ? flower like Stone- 

 crop, but upright). 



493. Ectinocera borealis, Zett., Lochinver, 30th June 1911. A 



single specimen swept off the unarmed thistle growing in 

 abundance round the spring close to the boundary of the two 

 fishing-beats on the river Inver probably less than half a 

 dozen specimens in all of this rare dipteron have been taken 

 in the British Isles, and most if not all of these have occurred 

 in Scotland. 



494. Sciomyza (Ditanid) cinerella, F., Loch Assynt, iSth July 191 1 ; 



probably common. 



495. Sc. (Ditcenia) brunnipes, Mg., Lochinver, 9th July 191 1. 



496. Sc. griseola, Fall., Loch Assynt, 20th July 191 1. 



497. Sc. pallidiventris, Fall., Lochinver, 7th July 191 1, a pair in 



coitu. 



498. Sc. ventralis, Fall., Loch Assynt, iothjune 191 1; The Mound, 



24th June 1904. 



499. Sc. nana, Fall., Loch Assynt, June 191 1. This specimen was 



given to Mr Grimshaw, but I am under the impression that 

 the species was more abundant than this single record seems 

 to indicate. 



500. Tetanocera robusta, Lw., Loch Assynt, 10th and 12th June 



191 1 ; Lochinver, 9th July 191 1; common round Loch 

 Assynt. 



501. T. punctulata, Scop., Loch Assynt, 26th July 191 1; uncommon. 



502. T. umbrarum, L., Loch Assynt, 12th June 191 1; far more 



abundant than the preceding species. 



503. T. Icevifro/is, Lw., Lochinver, 23rd June 191 1. 



504. T. unicolor, Lw., Loch Assynt, 10th June 191 1 ; uncommon. 



505. Limnia unguicornis, Scop., Loch Assynt, 20th July 191 1; 



uncommon. 



506. Elgiva lineata, Fall., Lochinver, 24th June and 19th July 



191 1 ; common. 



507. E. dorsalis, F., Loch Assynt, 1st and 5th June and 26th July 



1911 ; common.
