250 THE ENTOMOLOGIST. 



by a Nepticula which we suspect is the North European 

 species, tristis. 



We now come to a higher plateau, similar to the one we 

 have just left, and commence to search for Pachnobia. 

 Carefully inspecting stones is rather slow work when not 

 rewarded by finding anything, and the stones are legion (even 

 when the amusement is varied by getting an occasional 

 Psodos who comes to see what is going on), so we try tearing 

 up and examining the moss. This is a little more lively, as 

 an empty chrysalis-case (not to mention numbers of a bug 

 new to science, Orlhezia Signoreti) rewards our efforts, but 

 after a while we tire of that too. A herd of red-deer gallop- 

 ing past attracts our attention, and then, " Hi! mark that 

 thick body," and in half a minute more the net is over 

 PacJuiohia as he flies past. After a more or less (probably 

 very much less) successful search for more, we turn our faces 

 homewards, and finish up the day by sugaring the palings 

 and stones near the house, where, if fortunate, we may get 

 Crymodes exulis, and then go to our well-earned beds and 

 dream of all the new things we may get next day. 



In this slight sketch of the Lepidoptera of Glen Tilt, I have 

 merely mentioned the chief species that have been taken 

 within half a mile or so (as measured on the Ordnance map*) 

 of our head-quarters, and do not mean to say that we took 

 them all on one day, though I believe that that would be 

 quite possible. On another occasion 1 may describe a day's 

 collecting in another part of the glen.

ENTOMOLOGICAL NOTES, CAPTURES, &c. 



Absence of Colias P^dusa. — As for the "absence of 

 Colias Edusa in 1878" I can answer for its scarcity in 

 Swanage (Dorset), Weston-super-Mare (Somerset), Sheerness 

 (Kent); and, while in other years 1 have caught them in 

 some of the woods round Highgate, I have not seen one this 

 year. — M. B. H. Lane; 70, Junction Road, Highgate. 



Absence of Colias Edusa. — In reply to Mr. McRae, I 

 have not seen a single specimen of Colias Edusa this year 

 near Taunton, Somerset, where last year I saw it in great pro- 



* That is, on the level. The difference in altitude between our starting- 

 point and the Pachnobia plateau is very nearlj' :2000 feet, so the intelligent 

 reader can calculate what the working distance is. I make it about an hour 

 and a hall's steady walking up a very steep hill.
