1 52 ANNALS OF SCOTTISH NATURAL HISTORY 



GONIOMYIA TENELLA, Mg. Common on the moors at Dunachton, 

 Ballindalloch, and Carr Bridge. 



- C; MOLOPHILUS ATER. Mg. This was, to me, the most interesting 

 insect met with on the moors. It is a small species compared 

 with other members of the family, and remarkable for its 

 stunted wings, which, I should imagine, are perfectly useless 

 for flight. The fly is very common in certain of the marshy 

 areas around the sources of the rivulets, where, at the proper 

 season, it is to be seen climbing up and down the leaves of 

 grass and Juncus. Its white halteres are very conspicuous, 

 while the insect itself is curiously spider-like in appearance. 

 Hundreds of specimens were seen in one marsh at Dunachton 

 (many of them pairing) and a large number collected and 

 preserved both dry and in spirit. Of 26 chicks killed at 

 Dunachton no fewer than 14 were found to have been feeding 

 on this insect, and in 5 of these the crops contained over 100, 

 56, 50, 34 and 11 specimens respectively. 



~' I; RHYPHOLOPHUS NODULOSUS, Meg. Several specimens taken at 

 Dunachton. A single male found in a crop from the same 

 moor. 



ERIOPTERA TRIVIALIS, Mg. A common inhabitant of the moors. 

 Several examples taken at Dunachton, Ballindalloch, and Carr 

 Bridge. 



IDIOPTERA TRIMACULATA, Ztt. Of this rare and interesting fly I 

 took six males and one female at Dunachton. 



PCECILOSTOLA PUNCTATA, Schrk. - - One example of each sex, 

 Dunachton. 



LIMNOPHILA MEIGENII, Verr. A common species; many taken at 

 Dunachton. 



LIMNOPHILA LINEOLELLA, Verr. Females taken at Ballindalloch 

 and Carr Bridge. 



LIMNOPHILA BICOLOR, Mg. Common ; taken in numbers and in 

 both sexes at Dunachton and Ballindalloch. 



^DICRANOTA BIMACULATA, Schitm. One male of this rare species 

 captured at Dunachton. A male also taken from a crop from 

 the same locality. 



AMALOPIS IMMACULATA, Mg. 2 males and i female, Dunachton.

DOLICHOPEZA SYLVICOLA, Curt. A few examples of this extremely 

 beautiful fly were seen flying over a tiny stream at Dunachton, 

 and afterwards captured.
