14 THE ENTOMOLOGIST S RECORD. 



small one, about 200y(lR. lon^ and 20y(lR. wide, being one side of a 

 steep valley, some l-JOOft. or lOOft. above sea level, and about a mile 

 inland ; there is a good growth of wild thyme here, and no doubt on 

 this plant the larvse feed ; there are probably other localities in the 

 district, but I could not find one, though careful search was made. 

 Judging from the nature of the country, however, I should be surprised 

 if the species is not widely distributed along the coast of Argyleshire, 

 and amongst the Inner Hebrides. 



Specimens of Anthwccya filipoidiilaevfeve well distributed, but were 

 nowhere common. Four fine large Setina irrorella were in the nature 

 of a surprise, but as one of them was an IVI aberration fab. sif/nata) 

 the surprise was a very pleasant one. No night work being done, the 

 Noctuids were, of course, hardly seen, and the only species that calls 

 for note was Vlmia inti'rnxjatwnh, which was scarce. Amongst the 

 Geometrids more species were observed. Buarinia ri'pcuulata, of the 

 Eannoch form, was not uncommon, sitting on the rocks, and the 

 same remark applies to Dast/dia uhfioicaia ; GnopluDi uhacurata, large and 

 dark specimens were obtained ; Acidalia ftnnata occurred freely amongst 

 ling ; Lanntia caedata was not common ; of L. salicata two specimens 

 were observed ; L. ulirata was common, but local ; L. viridaria, com- 

 mon, large and well marked ; a few specimens of Kttpithecia jJulcJidlata, 

 of a very light form, quite different from southern ones, were sitting 

 on the rocks, and the larvte were very common in the foxgloves ; one 

 I'j. cansttiitata and a few larvje occurred in the A. purpKraliH (minus) 

 locality; Mdanthia ocdlata were common in one valley; Melanippe 

 ijaliata, with a very broad and dark band, were not uncommon. 



One day spent on Ben Cruachan was the most fruitful in collect- 

 ing of the trip: Knhia cpiplimn, Larcntia cat'siata, I'JiiiJiidcKia utittarata, 

 K. adeqiiata, Scojntla alpinalia, Craiiihus iricdluK, and C. funatdlus 

 were amongst other species taken. I believe this is an unrecorded 

 locality for i^'. epiplirun, in any case it is an exceedingly good one, the 

 butterHy swarmed all over the mountain, south of the Cruachan Burn, 

 and from 1,000ft. to 3,000ft. Had I not been intent on attaining the 

 summit, and had I so desired, no doubt several hundreds could have 

 been netted. A walk across the Island of Mull, from Salen to Loch Ba, 

 was, from an entomological point of view, the most barren of my 

 experience. Only one moth was seen, although the country round 

 looked most promising ; as this, however, was a form of Caiiijito- 

 (jra)niiia hiUiuata, which I do not remember to have seen previously, 

 with a black fascia, divided transversely by a yellow bar, the quality 

 was decidedly better than the quantity. The only larva; obtained, 

 except those before-mentioned, were about two dozen of IHanthvecia 

 amspcrsa, and a few Kupitlu'da renosata, feeding in capsules of Silene 

 inaritima, from which I hope to breed some interesting specimens next 

 year. 



Migration and Dispersal of Insects: Orthoptera. 



By J. W. TUTT, F.E.S. 



Almost all the insects known in popular language as " locusts " are 

 members of the family Anidiodia, of which there are probably 2,000 

 species already known to exist in diii'ereut parts of the world, and to
