could get out after them, but the opportunities of collecting them 

 were very few, as scarcely a day passed without rain. In 

 Sutherlandshire a good many of the species occurred only 

 in the male sex (which appear about a week in advance of 

 the females); while as for larvae, scarcely any were to be seen. 

 Although then, as regards quantity, my journey did not yield 

 much, yet several things were found that well repaid the visit, 

 and indeed showed how much better I would have done if the 

 season had been more favourable. Around Bonar Bridge the 

 most interesting species met with was Cyphona geminata, Dbm., 

 of which one specimen turned up by sweeping on the banks of 

 the Carron; this insect is rare everywhere, and hitherto only 

 found in the South of England. At the same place I bagged 

 three males of Taxomis agrorum, Fall, {nitlda, KL), an insect which 

 I was well pleased to see, as I was doubtful of its British nativity, 

 which was thus placed beyond question. The male differs from the 

 female in having the neuration of the posterior wings formed as 

 in Perineural a difference which led Eversmann to describe it as a 

 new species under the name of Taxonus anomala. Near Lairg 

 I captured among the birch woods a Nemakis, which I have no 

 doubt is the N. canalmilatus of Hartig, not hitherto recorded 

 for Britain. Near the Falls of the Shin I fortunately came 

 across several larvae of Neraakis letulae, Eetz., this also being 

 new to the British fauna. Of known British species the most 

 noteworthy met with was Fenusa melanopoda, Cam., on Alder, a 

 circumstance which seems to show that it was its larvae and not 

 that of loumila which Zaddach and Goureau described under that 

 name. Neraatus faJlax occurred on Salix fusca, thus considerably 

 extending the northern range of this species in Scotland. N. 

 dorsatus, Cam., was captured not rarely; Athalia gldbricollu at the 

 mouth of the Dornoch Firth; and Nemakos apj^endiculcUus on the 

 banks of the Shin at Invershin, this form having only hitherto been 

 found in Braemar in Scotland. 



Towards the end of my stay I paid a visit to the interior, and 

 stayed at Altnaharra, where my best captures were made. On the 

 first day it poured, but the next was very fine, and an ascent was 

 made of Ben Clibrich, the second highest mountain in the county. 

 In ascending I found a dipterous gall (formed of thickened terminal 

 leaves), on Vaccinium vitis-idaea, which had been found previously by 

 Prof. Trail at Braemar, but the maker has never been bred. At an
