The Scottish Naturalist. 197 



August 1872. I am not aware that it has been otherwise 

 observed here. 



Eupithecia pulchdlata. — Common some seasons near the food- 

 plant. Most of my specimens were taken at rest on, or disturbed 

 from, rocks or stones near beds of foxglove, at an altitude of 600 

 feet and upwards. Some specimens are dark and very richly 

 marked. 



E. ceiitaureata. — Not common, but fairly distributed. I have 

 taken it at night on wood-sage blossom ; and Mr Herd tells me 

 he has found it at rest on thistle and ragweed stems in the 

 daytime. 



E. subfuivata. — Not common. I have one very beautifully- 

 marked specimen, which Mr Guenee considers to be the variety 

 oxydata. The late Mr Doubleday's opinion (see ' Scottish 

 Naturalist,' vol. iii. p. 266) was at variance with Mr Guenee's \ 

 and if two such authorities differ, the less I say the better. 



E. pygmcEata. — Rare, though not uncommon in close proxi- 

 mity. 



E. satyrata. — Frequent at all times. Sometimes common. 

 The var. callimaria of Mr Stainton occurs most frequently ; but 

 I have taken specimens which approach very closely to the 

 English type in the same locality. 



E. castigata. — Common and generally distributed. This 

 genus is so difficult to determine that it is impossible to be 

 always quite certain as to the identity of wild specimens. Casti- 

 gata and lariciata are so closely allied that it is quite possible 

 there may be a third species here mixed up with them. I do 

 not in any way assert this to be the fact, but I confess to a diffi- 

 culty in separating all I take. 



E. lariciata. — This is a most variable species here, as men- 

 tioned above. Some freshly - emerged imagos have a most 

 beautiful rosy patch in the centre of the fore-wings, making them 

 appear as distinct from '■'■lariciata^'' as that insect is from '■'■ siib- 

 fiilvata!'' But, alas ! after a time it fades away, and in a few 

 months leaves little or no trace behind. Mr Harpur Crewe, 

 however, to whom I submitted most of my specimens for exam- 

 ination, does not appear to have the same difficulty in identify- 

 ing them, so I "cave in." 



E. indigata. — A very common insect amongst Scots fir. It is 

 disappointing that E. fraxinata has not turned up here, as the 

 food-plant (ash) is a perfect weed. 



E. iianata. — Fairly common. All the specimens I have seen
